In May 2017, I accepted a job offer at the Wisconsin IceCube Particle Astrophysics Center (WIPAC) in Madison - a job that will send me to the bottom of Earth. IceCube is a giant Neutrino detector at South Pole, and it will be my job to keep its computers running. For an entire year (November 2017 to December 2018) I will live and work at the Amundson-Scott South Pole Station in Antarctica. Being an IceCube "Winterover" has been my dream job for years - und now the dream is real. This page is my journal of this once-in-a-lifetime adventure.
Most of the content will be in English, but I might write in German occasionally. The journal entries are sorted by date (latest first).
We broke another wind record today! You can hear the wind howling and feel the station shake in the gale. The weather has been a real a-hole the last couple of weeks, which turned any outside activity into an almost-suicide mission. All the outbuildings are connected to the station by flaglines that help you find your way in the dark - but these days you can't even see from one flag to the next, which makes working outside so dangerous that our safety engineer Ted installed sign-out boards at all the exists, so that if you really have to leave the station, people know where you are and when you're supposed to be back. Luckily, no incidents so far. Fingers crossed.
You know how being trapped inside makes me toasty, and on top of all this I beat the "Zelda" video game I've been playing over the last months - bored AND grumpy is a dangerous combination! So for the sake of occupation, Tribble and I decided to do a little photo tour around Amundsen-Scott. Also because mom and dad kept bugging me about it. <3
If you've been following this blog for a while, you've already encountered a few important places on station, like the big gym, the galley, the power plant or the communications office. Today I'm gonna show you some more corners of my home away from home.
Amundsen-Scott South Pole Station is built on giant adjustable pillars that currently hold it about 5 meters above the ground (that's why it's sometimes called the "elevated station"), so that the wind can blow underneath it and we don't get buried in eternal snow. It's symmetrically divided into A- and B-Pod, which each have four sub-pods. A1, A4, and B1 are the berthing pods, where A4 is only occupied in the summer and used as food storage during the winter. A1 has the biggest rooms so it's the preferred sleeping area, but some of us (me) choose a small B1 room over the crowded A1 - you basically have a whole hallway to yourself, and in my case I even have my own bathroom!
Together with the big gym that lives in B4, the berthing pods form the four finger-like station extensions that you can see in some of my photos, like this one. Among other things, A2 holds the galley, A3 is home to all the offices, the science lab is in B2 and comms and management live in B3. You enter the elevated station either through the main entrance "Destination Alpha" or short "DA" to the B3 pod; the cargo entrance "Destination Zulu" or short "DZ" between A1 and A4 pods; or through the Beercan - the staircase outside of A2 that is shielded from the wind by a round sheet metal structure that literally looks like a beercan, as you can see in this photo.
In case of a major disaster - let's say the complete A pod burns to the ground - the B1 pod (where I live) serves as a lifeboat. It has it's own little power plant, kitchen, laundry room and pool table, and is separated from the rest of the station by big-ass fireproof doors. Let's hope we never have to use them.
Once again the moon rises over Amundsen-Scott South Pole Station, and once again it brings with it some pretty peculiar weather. Peculiar in the sense of mayhem and madness, with 30 knot winds and zero visibility. Bleh. As you know, the weather has a non-insignificant influence on my mood - but even a storm can have unexpected surprises up it's sleeve.
So as I am shuffling down the tunnels for my daily fuel rounds on Sunday morning, I stumble over a pile of snow as tall as me in the VMF arch - a sastrugi that was pushed through the cracks in the doors by the storm. That guy was nothing compared to what we found in the logistics arch the next day! That stuff you can see in the pictures came through the closed doors a snowflake at a time - just to give you an idea of how windy it really was.
Anyway, we also had one nice day last week - that is, a couple of nice hours in an otherwise equally shitty day. Travis and I seized the opportunity for some aurora watching in the backyard.
A bunch of people I've never met have been writing me the nicest digital letters over the past months, to wish me all the best for my time on the Ice, to re-connect with the continent they visited many years ago or just out of curiosity. The question I've been asked in these letters a few times now is "do you get zapped a lot?" The answer is: Yes, only all. the. time.
I guess it's because of the low pressure and the insane dryness, that things just build up crazy electrostatics that, in the real world, would just slowly be discharged through the air. Not at South Pole! Here you get zapped basically every time you touch something metal. And sometimes it really hurts! The other day I walked up the station outside stairs and touched a hand rail which dumped so much charge through my bear mittens that you could see it spark. Autsch!
This really becomes a problem when you are working on electronic equipment, like your camera, or the over a hundred shit-expensive servers that we have in ICL. You can absolutely kill one of those by just touching it, that's why we wear ESD jackets (lab coats with wires woven into the fabric) and dissipative wrist bands in the server room at all times.
The human body needs sunlight to generate happy-vitamins. We don't get sunlight here, so most people take supplements. I do, too, but that's not all it takes. I go outside almost every day to look at the stars and get my dose of totally imaginary starlight-vitamins. ... But after two weeks of total shieet weather which made it impossible to stick your nose out, people could tell that I wasn't taking it too great. Grumpy, cynical and homesick me probably wasn't too fun to be around.
Two days ago, the sky finally *FINALLY* cleared up again, the wind died down, and people could watch me in my Big Red outside, lying on my stomach in the snow and embracing my sweet sweet -60° C with zero windchill, trying to get my starlight-tan back. What a time to be alive.
I guess everybody has their own way of keeping their peace of mind at the end of the world, and mine definitely lies outside in the night sky. That's why I spent every free minute I had these last couple of days all around Amundsen-Scott South Pole Station, taking pictures and being happy. And as if to apologize for the two-week long shitshow, mother nature gave me my favorite auroras when I went outside on Wednesday in the middle of my night: Gigantic purple and green pillars of light, just hanging there in the sky, seemingly motionless but constantly changing. Nobody else was out there, and I'd like to believe this was just for me. In case the weather will get bad again (very likely), that moment made my entire week.
Johannes and I also seized the opportunity to do some work on the roof of ICL. For that, the weather has to be just perfect - because for some reason, if it's stormy around station, it's that times a hundred out at ICL, and on the roof especially.
Mileage: 329.43 - Finally hit the 300! I kept taking it a little slow to give my knees and feet a break, but so does Ta-Lee. He's currently about two miles ahead.
Ice facts #13 South Pole weather (again!)
The weather has been so shitty that I was planning on dedicating this whole journal entry to ranting about it. But you can't really be mad for a long time when you get compensated with auroras, so I'm just gonna make this an informative one instead.
Two things go well together at South Pole: Warm and windy on the one hand, and cold-as-fuck and not-windy on the other. You almost never get cold-and-windy or warm-and-not-windy. You can see two examples for warm-and-windy from last week in the pictures below.
If you ask me what I prefer: I'd take -80° C without wind over -40° C and 25 knots anytime, and I'll bet every other winterover would say the same. No matter how many layers you wear and how windproof you think your cloth are - the wind will find you and it will hurt you. Goggles are not a thing in the winter, because the heat and humidity generated by your own face is enough to make them freeze over within seconds. So people usually go with the Eskimo-slit technique, where you cover up your whole face except a tiny portion where your eyes are. The air you breathe out through your gaiters usually is warm enough to keep that patch of exposed skin frostbite-free - unless it's windy, then your only chance is to either walk with your face faced away from the wind or cover it up with your mittens. Either way, you're not gonna be able to see. Wind sucks! :D
With my hands wrapped in three glove liners and bearpaws (the heaviest kind of mittens we have), chemical and electrical handwarmers in between, I sit on the ice watching the incredible light show above me. The display makes me almost forget my "scarfies" - when your hands hurt so bad that you want to scream and barf at the same time - which made me want to go back inside so desperately just a minute ago.
But right know I'm too busy not being able to decide which way to turn my head: To the swiftly dancing purple lights right above me or the slow moving green and red ribbons in the distance. The moon is still up, so it's probably light enough for people on the observation deck to see me running around like a chicken, trying to get the best possible view of the auroras. I don't think anybody could hear me howling at the moon though. ;)
There are times when South Pole is trying to kill you. Which is literally every second. But there are also times when South Pole is trying to kill you a little less, and those who endure the bitter cold just long enough, are occasionally being rewarded by an unforgettable display like this. Although the show lasted for hours, I consider myself less brave for withstanding the cold rather than extremely lucky - solar bombardments like this are rare even here at South Pole, and I am grateful for being one of the fortunate few to witness it.
It's finally boring enough down here so that I can start writing about science. ... Nah just kidding, this is gonna be awesome! Because science is awesome! Science yeah! SCIENCE!
As you might know, I was hired as an astroparticle physicist to watch over the IceCube Neutrino Telescope here at South Pole. The name itself poses a bunch of questions already: What are neutrinos? How is IceCube a telescope? And why at the South Pole?!
Let's tackle the first question today and learn about neutrinos. They are very fascinating little guys, that live in the lepton family of the Standard Model of Particle Physics which is visualized on the right. The model holds all elementary (that means indivisible, unlike neutrons and protons or whole atoms) particles that we know of today: The quarks, which are the building blocks for protons and neutrons and therefore all matter we see around us. The gauge bosons, which are the carriers of the four fundamental forces - gravity, electro-magnetism, strong force and weak force. The recently discovered Higgs boson which "gives" mass to other elementary particles in the model. And the leptons, which are, among other things, defined over their 1/2-integer spin. For each quark and lepton, there exists an antiparticle with identical mass but opposite electrical charge.
The best known lepton is probably the electron, which per definition has an electric charge of -1 and can form atoms together with protons and neutrons. The muon and the tau are pretty much just heavier electrons. For each of these three there exists an uncharged counterpart, the electron-, muon- and tau-neutrino, represented by the greek letter υ. We know about them only since they were postulated by Wolfgang Pauli in 1930. Why? Because they're incredibly hard to find. Elementary particles are so tiny that we can only "see" them when they interact with things, like an electron being pushed around in a magnetic field. Neutrinos however do not take part in electro-magnetism, because they do not carry electric charge, unlike their lepton brothers. They only reveal themselves in interactions of the weak force, which - you could say - is the "rarest" of the forces (also pretty complicated, so let's cover that in a different session). "What about gravity?" you might ask. Well, technically you're right, but the neutrino masses are so incredibly small that gravity basically has no impact at all, at least not on a scale we could measure. Fun fact: According to the Standard Model, the neutrinos should be completely massless. Nowadays we know they actually do have tiny masses, although the exact values are still a mistery. Their property of being a pain in the butt to find, and the fact that we still do not know a lot about them, awarded the neutrinos the nickname Ghost Particles.
So why do we care about neutrinos? First of all, because they're there (which, for a physicst, is an absolutely sufficient but not necessarily required condition :D)! Second of all, they are considered ideal cosmic messengers. What does that mean? Well, neutrinos are not influenced by cosmic magnetic fields, neither are they likely to interact with anything like dust clouds or radiation - so they basically travel through space in a straight line unimpressed by whatever may try to deflect them from their path. The highest-energy neutrinos originate in powerful cosmic objects like supermassive black holes or active galactic cores, so they carry precious information from the very inside of these objects with them. No other particle can do that. Neutrinos are the unicorns of space!
-18°! Nope, that's not the temperature, but the altitude of the sun below the horizon. That means astronomical twilight is over, and it's finally really dark at South Pole. On a calm day, the Milky Way is clearly visible, and the auroras are brighter than ever. But remember I mentioned how we can not see the snow beneath our feet? Yes, that became a real problem now. We are not allowed to use flashlights because of the sensitive aurora cameras on the roof, and the red headlamps we carry do not help an awful lot. So I eat it at every little sastrugi on my way out to IceCube. Fortunately we wear so many layers that it's really hard to get hurt, and the heavy snow boots prevent lots of sprained ankles. Although I'm less worried about falling on my face, but about breaking my beloved camera which I almost always have with me...
But not for the next one and a half weeks! The moon is up again, and it's so bright that it casts distinct shadows on the ice - which makes life at Pole so much easier right now.
There's only two options for the day after a big celebration: Wake up hungover, have Aspirin dissolved in mayonnaise for breakfast, go back to bed and feel sorry for yourself. OR you wake up hungover, let Mikey put a fresh mint julep in your hand and embrace the party-afterglow by watching the Kentucky Derby over satellite in the galley!
Apparently the Kentucky Derby horse race is a biiiiig deal in the United States. And by big deal I mean it's another excuse for people to get drunk and spend money on stupid things - hell yeah! So we spent all Sunday morning in the galley, being lazy, having leftover-brunch, knitting, and watching the Derby on DSCS. It took me till noon to find out that the actual race is only about two minutes long, but of course the Americans make an all-day TV event out of it. The satellite connection was great, right to the point when the jockeys saddled up; and funny enough, we spent the entire race staring at a two-minute buffering screen. That's South Pole :D
Sundays at Pole are usually pretty chill. It's most folk's only day off, which creates a lazy vibe all over the station. It's a day for relaxing in the greenhouse or the sauna, playing video games, watching movies or taking a walk. Or finally catching up with blog entries you were too busy writing during the week...
Another American holiday I didn't know was a thing: Cinco de Mayo! It's basically the same concept as St. Patrick's Day: A foreign nation's noble culture gets brutally reduced down to a few very stereotypical clothing items, and then everybody gets drunk. For some reason Cinco de Mayo is considered more offensive than it's Irish counterpart, so let me put together a little disclaimer just in case: We all had a ton of fun dressing up and decorating the lounge Mexican-style, had awesome Mexican food and just enjoyed the party - I very much hope nobody can find anything offensive in that; if there are any concerns with the contents of this journal entry please let me know.
The historical background of this holiday is the defeat of the French in Mexico some time ago, I don't really want to get into this. Fact is that for some weird reason we have a trizillion sombreros on station, and the 5th of May is the perfect day to get them all out. And to have home-made nachos and margaritas. Also, our supply specialist Steve (the guy with the cardboard T-Rex) made piñatas! In case you are not familiar with the concept: A piñata is a colorfully decorated cardboard structure resembling an animal, a geometric shape or in our case, a taco, which is usually filled with candy or some sort of treats. The lovingly designed object then gets beaten the shit out of by a blindfolded person with a baseball bat. Oh, Murica.
In case you wonder: No, it is not a terribly great idea to hand a baseball bat to a blindfolded adult that just had a margarita. But since we are all responsible human beings, the only incident was accidentally torn down paper decoration by our safety engineer Ted. Safety third, Teddy!
The sun is now about 14.5° below the horizon (remember, it only goes as low as 23.5° as explained in Science facts #5), so it's finally dark enough to enjoy the auroras in their full glory, even with the naked eye. I get asked a lot if they actually look like in the photographs - nope, they don't. It's less bright and the colors are less obvious (I'll try to take a photo that comes close to what the human eye can see for my next report). But on the other hand, a camera will never be able to capture the magic that happens if you just lie there on the ice and enjoy the gigantic glowing ribbons that appear out of nowhere and are then gone forever, sometimes just to make way for an even more impressive light show. It's important to remind yourself that the world shouldn't always be observed through a camera lens.
But yeah, sometimes me and my beloved Sony Alpha 7II just get carried away. So today I'm just gonna show off a little bit - enjoy!
Mileage: 248.70 - Ta-Lee finally got me. But my feet and knees definitely needed a break. Man I miss running outside. Treadmills suck.
Ice facts #12 Where the Internet comes from
To most people in the western world nowadays, communication is an abstract, invisible, self-evident matter of fact. The only time you notice it's there, is when it's not. And that happens a lot at South Pole.
Amundsen-Scott South Pole Station is so remote from the rest of the world, that the only way of communication is - through space. Only downside: Most communication satellites don't fly over the poles, because nobody freakin' lives there :D So we are currently piggybacking on three different systems that barely touch the South Pole horizon: DSCS, Skynet, and SPTR2 (explained in the picture on the right). All three of them are visible for only a few hours each day, and provide very different bandwidths. DSCS is by far the nicest of the three, and the connection of choice for things like YouTube, Facebook, online banking, phone calls, etc. SPTR is okay-ish but requires a little bit of planning sometimes. It's super patchy and not very fast, but if you pre-cached all your websites on DSCS, you can still use them on SPTR. The network is also used to upload all the science data, including pretty IceCube events. Skynet (or "Sucknet" as the winterovers call it) provides barely enough bandwidth to ping the Google servers. It's slower than Christmas, but better than nothing (I guess). The overall daily satellite coverage is roughly 12 hours, with about 8 hours of actually usable bandwidth.
The station has a 24 hour Iridium coverage for emergencies - you technically CAN make a phonecall on the Iridium line, but it's not pretty. Email works.
What we really absolutely do not have is Wifi and cellphone reception. So guys, please stop whatsapping me, IT WON'T GET HERE :D
Our two satellite communication (satcom) engineers, Tony and Josh, track the different satellites with gigantic dishes in the so-called raydomes - the domes protect the equipment from wind and weather. Earlier this week, the guys took me out there to show me around. It's quite the walk, but totally worth it, especially if your way is lit up by the prettiest auroras!
The first Aurora Australis of the year! At least the first ones I've been lucky enough to capture with my camera. People have been spotting auroras throughout the entire last week, but I always happened to be too slow or too busy to catch them. Today, my original plan was to get a photograph of the flare of IRIDIUM 81, but I got a lot more than I asked for. If you take a close look you see that there's so much stuff going on in that photo! (Fun fact: IRIDIUM satellites are not made out of iridium at all. The name comes from the initial plan to launch 77 of those satellites, where 77 is the atomic number of Iridium. Yes, that's the whole reason. Also, they ended up only launching 66 so they should be called Dysprosium satellites. I learned that in Robert's astronomy class!)
Remember when I went out to MAPO to winter-proof my camera equipment a couple of weeks ago? It came a long way since then! Over the last few days I've been crafting and optimizing a sweet windproof camera sleeve from scrap outdoor fabrics I found in the arts-and-crafts room. It has two layers of fleece, one layer of waterproof nylon and one layer of windproof fabric. And it works! It's shielding my equipment from the -90 °C winds long enough that I can take my time with finding the right spot, angle and settings and still take pictures for at least 30 minutes before the battery runs out and the LCD freezes - and that's way longer than my own hands last in the weather! And certainly long enough to take a few pictures like the one above.
Mileage: 217.30 - Over a quarter there already! I'm currently still 14 miles ahead of Ta-Lee, but he's catching up... Gotta watch out for my knees a little bit.
On April 12th 1961, Yuri Gagarin's spacecraft completed an orbit around Earth which made him the first human ever in outer space. The anniversary of this event obviously has to be celebrated at Amundsen-Scott South Pole Station! Robert organizes the party every year and invites the crew to dress up as spacey as possible - and people delivered! See for yourself in the picture above. We had a cosmonaut with a giant head, Space Trash, at least three Arthur Dents and a Space Wolf. And yes, I wore my Starfleet uniform with pride! I always do! Everybody who showed up without a costume got a brain slug smonched on their head. That's what you get for not dressing up.
Besides Yuri's Night, the whole week was all about cardboard. I helped Ta-Lee to unwrap the aurora cameras on the roof of the station - which officially heralds the aurora season, but also requires all station windows to be covered with wood or cardboard, so that the sensitive cameras are not disturbed by stray light. Since it's super lame to stare on plain cardboard for six months, people decorate the window covers. This season, in order to get rid of the old, torn-up covers that have been used for years, but also to keep people busy and happy, our station manager Marco organized a cover-art-contest: Whoever comes up with the nicest design, will have his or her next dishpit duty covered by Marco himself! We don't have a winner yet, but some of the submissions are shown in the picture below. Also, window covers are not the only thing you can make out of cardboard: Our supply specialist Steve gathered some minions to construct a gigantic T-Rex and put it up in the corner of the galley. Pretty impressive!
There's nothing more uncomfortable than not seeing the ground beneath your feet. The twilight we are experiencing right now is still bright enough to see distinct shapes like flags and buildings, but small shadows cast by minor snow drifts - not a chance. So the ground looks perfectly plane and smooth, which it is, of course, not. On my way to the Dark Sector the other day I ate it at least five times, including rolling down the slope that surrounds the MAPO building which started way earlier than I expected. The only advantage of the low light conditions: Nobody can see you falling on your stupid face :D
What was I doing at MAPO anyway? Robert Schwarz, who is doing his 14th (!) winter at South Pole and basically lives at MAPO, has offered to help me with my photography equipment, so I gathered all my gear and ventured out there. Even though all that stuff costs a fortune and is high-end technology, it is in no way whatsoever designed to be used in -70 °C. Plastic and rubber parts crumble upon the slightest touch, cables break like uncooked spagetthi, and the grease that is supposed to smoothen the moveable parts of your tripod "turnes into super glue", as Robert calls it, within seconds. Also, the LCD freezes after a few minutes, but unfortunately there's really not a lot you can do about that. So together we replaced the grease in my tripod and swapped the plastic cable of my remote shutter for a Teflon cable. After all, I want to be prepared for the first auroras!
Another upside of visiting Robert at MAPO: He has all kinds of treats from home out there (he's from Germany, too)! Nothing compares to breathing in the fumes from your soldering iron while eating Rosinen-Marzipan-Stollen and listening to recorded Bayern3 radio. I also got to practice my German a little bit - I am shocked by how hard a time I have by now talking in my native tongue.
Oh I almost forgot: We had some lunar activity last week - if you paid attention earlier, you know that Earth's biggest satellite doesn't set for two weeks in a row at South Pole. The rise of the full moon last Sunday simply blew my mind away: It is huge! None of the pictures are photoshopped. South Pole keeps surprising me over and over again.
Anyways, thanks again Robert for the free telescope ride and for making South Pole feel a little bit more like home :)
The area around Amundsen-Scott South Pole Station is divided into a bunch of sectors; a few of them you can see in the picture on the right. Those sectors are mostly for protecting the science experiments that are going on down here.
The Dark Sector is home of the IceCube Laboratory (ICL), the Dark Sector Laboratory (DSL) which hosts the South Pole Telescope and BICEP, and the Martin A. Pomerantz Observatory (MAPO) building which hosts the KECK experiment. In terms of visible light, the Dark Sector is as dark as any other sector - in terms of other frequencies, however, special rules apply to this sector to avoid interference with the very sensitive experiments. For example, your radio has to be off at all times, your phone has to be in airplane mode, and all bluetooth and WIFI devices should better be left at home. You are allowed to use your radio in case of an emergency, of course.
The Clean Air Sector is home of the Atmospheric Research Observatory (ARO), which is where the two NOAA (National Oceanic and Atmospheric Administration) winterovers spend most of their time. As the name implies, the air in that sector is the cleanest on Earth. The air is pretty neat at South Pole in general, but the wind usually blows from ARO's direction which prevents exhaust from the station or vehicles to drift over NOAA's sensitive atmosphere experiments. Also, please don't fart when you're out there.
Deep underneath the ice sheet, there are buried some seismic detectors which are part of the South Pole Remote Earth Science Observatory (SPRESO) in the Quiet Sector. They monitor shockwaves in our planet, like earthquakes or nuclear explosions. They even detect the slightest vibrations on the surface of South Pole, which is why vehicles are prohibited in this sector.
All the aircrafts usually land in the Downwind Sector (if they don't overshoot the skiway for thousands of feet, chrmmchrm :D). In the winter, not a lot happens here, except the occasional meteorology balloon launch.
Sometimes, when all hope seems to be lost, a single sunbeam can restore a winterover's faith in the universe. Literally. The few days after winter equinox at South Pole are said to be the prettiest - unless they are shadowed by the biggest snow storm of the season so far. Wind speeds of 36 knots mean instant frostbite to any tiny little patch of exposed skin; they also mean zero visibility due to blowing ice crystals everywhere. Normally, I like this kind of weather, when you can not tell the difference between right and left, up and down; and the Japanese flag at the Ceremonial Pole marker appears as a single red dot floating in the air. But this week, I very much don't like to be in a "giant pingpong ball" as our meteorologists call it. It's the week of sunset, and that's really not something you want to miss. After all, it's gonna be the first and last for my entire stay here.
So yeah, of course the weather was shitty during the entire week. The storm raged non-stop for five days after the winter equinox, so everybody basically gave up hope on seeing the sunset. The sun is visible at Pole for several days AFTER it set - or rather it's reflection in the atmosphere, so you can not really predict when the sun will be visible for the last time. Also, if you're lucky, you can witness a phenomena called the green flash - a line of green light right above the setting sun generated by refraction in the atmosphere, usually visible for a glimpse of a second if at all, but which at South Pole can last for several minutes or even hours. Anyways, after five days, it was pretty unlikely that the sun would show up again even if the sky would clear up. Which it, in fact, did. I woke up on Sunday morning to the most beautiful play of colors across the sky - the pictures you can see below don't come even close.
So I grabbed my camera and my ECW and basically spent the whole morning outside, once again realizing that coming down here was the rightest decision I've ever made. Just sitting there and enjoying the breathtakingly beautiful display - until I frostnipped my butt. Again. Totally worth it.
All disappointment about our "short" sunset immediately vanished upon being seated to the most amazing South Pole Sunset Dinner. A fantastic seven-course meal, prepared by the best galley crew ever, accompanied by a selection of our finest wines, totally made up for everything spectacular that we might have missed out on. After all, we will get another chance - at sunrise in eight months.
Over the course of the last months, I was being introduced to all kinds of American culture. By now I think it's fair to say that most of it is about food and booze - like in every other country. And the Americans have a special history in deep-frying things. All kinds of things. If, however, a particular holiday does not, for some reason, dictate the consumption of deep-fried food, they come up with other sorts of crazy things, like brutally over-sugared beverages, hopelessly over-frosted cake or a ridiculous-inflationary usage of food dye. But don't get me wrong - I love it! Except maybe the sugary drinks, I really can't warm up to that stuff. Burghs.
Anyways, Saint Patrick's Day is no exception. I've never had green beer ever before in my life - and now I know why! :D In our bartender's defence: They did not have particularly great beer to begin with, so dying it green wasn't gonna make it A LOT worse.
It may sound like I am making fun of my American friends - and that's absolutely not wrong. But only because I love them so much! :) Honestly I think Amundsen-Scott South Pole Station has not seen a winterover crew like this ever before. Everyone knows wintering at South Pole is my dream - but this particular bunch of crazy individuals makes it so much better than I expected! Speaking of great people: Our machinist Steele (oh yes, that's really his name) made me the most awesome mute for my fiddle! I started self-learning last Wednesday, and ever since I was horribly afraid of being lynched by basically everybody who lives in B1 (if that actually happens, the suspects are Travis, Ta-Lee, and Josh). But now that I have my mute I can safely practice in my room whenever I want. Sadly I wasn't able to perform at Paddie's Day, but be prepared for a big concert at Midwinter! Tickets are free!
Last time I told you about what the moon is up to - I figured this time you might be interested in what the sun is doing at South Pole right now. And let me tell you, it's all kinds of shenanigans! Official equinox is next Wednesday, around 5 am local time. That means the sun is pretty low already, and it's noticeably darker around here. Sunset comes with all kinds of pretty sights, and I started to drag my camera around with me wherever I go. And that's rewarded with some pretty neat shots! These are my favorites :)
If you're curious about how the sun works here at South Pole: I picked a few things up in Robert Schwarz's last week's astronomy class. Click this: Science facts #5.
To understand what's going on in this week's science facts, you need the following vocabulary:
Solstices happen twice a year; they are defined as the days the sun reaches it's respectively highest (in the summer) or lowest (in the winter) altitudes in the sky.
Equinoxes are the two days of the year when day and night are of exactly the same length. At the poles, the equinoxes are the moments of sunrise and sunset.
Earth's rotation axis is tilted about 23.5° relative to the perpendicular to its plane of movement around the sun. That's the reason for seasons on our planet! It's also the reason for night and day at South Pole - if the axis wasn't tilted, Amundsen-Scott South Pole Station would be at the edge of dawn year round. But because things are how they are, we get one long day and one long night. The ostensible movement of the sun across the South Pole sky is illustrated in the picture below: It basically draws big circles seemingly without change in altitude every "day", with those circles slowly moving towards or away from the horizon. The sun's highest point in the sky is at summer solstice and measures 23.5° from the horizon, which equals the tilt of Earth's rotation axis - makes sense, doesn't it? It's hard to wrap your head around it at first, but maybe it helps to look at how the sun "moves" right at the equator: It rises and sets exactly perpendicular to the horizon every day of the year, with its highest altitude at the zenith straight above your head on the equinoxes, and its lowest altitude about 66.5° (= 90° - 23.5°) either from the north or south horizon on the solstices.
The polar day therefore is equivalent to the polar summer, as the polar night is to the polar winter. The nicest consequence of all this: Sunrise and sunset both seem to take about a week! If the weather is not shitty (which it might be according to our meteorologist Janelle) I'll show you some awesome photos next week.
Fun fact: The average time of daylight per 24 hours is exactly 12 hours for EVERY place on Earth, even the Poles. It makes sense if you think about it! :)
The moon is up! For those who never thought about it or missed Robert Schwarz's last Tuesday's astronomy class: Here, the moon is down for two weeks and then up for two weeks in a row, and it's really pretty in South Pole's clear air - except when it's not. Winter comes with more frequent whiteouts, and temperatures have been dropping significantly lately. -100° F (-73° C) with windchill are not uncommon any more.
As working outside becomes more uncomfortable with every day closer to sunset, the winterovers try to make their station as cozy as possible. The galley is now basically a big lounge, people started to put up hammocks in the B2 science lab, and Carhardt overalls are slowly but steady swapped for pyjama pants. Most outside activities, like frozen kickball and frisbee golf, are replaced by Trivia nights and station-wide games of Assassins and Werewolf, where a mysterious murderer - or "Thingatourwolf" - kills a person every night and watches people turn on each other in oblivion as population is slowly shrinking. Fun times.
"Comms, comms, this is flight deck: Otter CKB is off deck. Again: Charlie-Kilo-Bravo is off deck!"
That's it. We're alone. The last aircraft of the season, a Twinotter on its way home to Canada, departed Amundsen-Scott South Pole Station airfield. We sent them off with 700 gallons of jet fuel and a doggie bag full of cookies - hoping for them not to return for the next nine months. Because if they would, that would mean we're in big trouble.
South Pole is isolated for the winter season which lasts from Mid-February till beginning of November. During this time, nobody can get here, and nobody can leave. Period. However, it happened a few times in the past that someone on station was diagnosed with a bad-enough condition so that they had to be "med-evac'd" (evacuated for medical reasons). That's an endeavour that not only costs a fortune, but also takes several weeks, depends on perfect weather conditions, and requires everybody on station to work together flawlessly - and there is no guarantee for success. But don't worry: Every winterover underwent very thourough medical screenings prior to deployment to make the event of a med-evac as unlikely as possible. Also, we have a very capable crew in the sickbay - I trust my life to our doctor Malcolm and his assistant Brent.
Rather than the fear of getting sick, there is another paranoia that has been spreading among the 40 winterovers lately: Rumor has it that The Thing is back on station - an ancient alien creature that has been waiting for its awakening in the ice; to infect, imitate, and kill the station population. Slowly, silently. One by one. Luckily, we still have 24 hours of sunlight every day, which keeps the my-fellow-winterover-is-possessed-by-alien-parasites-panic down a little. For now.
Station Closing comes with another important event: The start of the Run to McMurdo, which is explained below. You can keep track of my progress in all my posts from now on. Run Raffi run!
The distance from South Pole to McMurdo is 835 miles, measured on the way of the Traverse. The Run to McMurdo challenges you to cover this distance within the 9 winter months - virtually on the treadmill, the stationary bike, on skies, the unicycle or whatever weird form of mobility you can come up with.
Now the fun part. I have a little bet going with our research associate Ta-Lee: Whoever makes it to McMurdo first, gets to dress the other person for a week. Yes, FOR A WHOLE WEEK. Everything faster than 5 miles per hour on the treadmill counts.
By the way, running at 3300 m elevation and zero humidity is a lot harder than you think. The extra air you need for exercise: Just not there.
Fighting the immediate urge to stumble backwards, I wave my arms towards the approaching monstrum in front of me, signalling it to keep going, as I try to hold my current position just a little longer. The spinning propellers could easily atomize a snowmobile, not to mention a tiny fuelie in a big red. I can feel the low BRRRRRRRRMMMMMMM of the throttling engines in my stomach as I draw a big X in the air, signalling the pilot to halt.
"Comms comms, this is flight deck: Skier 93 is parked in fuel pit one!"
I am pressing the headphones against my ears as I yell the words into my radio, over the sound of the four idling rotors of the LC-130 that is now sitting no 20 meters away from me in the fuel pit. The ice-cold wind that is blowing in my face does not make it easier to write down the Hercule's arrival time in the log book. Now: Get the nozzle, connect it to the hose, grab the bonding cable and wait for the loadmaster to wave you over! I've done this a dozen times, but I am still repeating the steps in my head to not forget anything. As the Air Guard officer finally gives me the sign, I start walking slowly towards him; the bonding cable in my one hand and the nozzle with the green hose over my shoulder. This is the most exciting part, but at the same time very exhausting and sort of horrifying - the hose is heavy and awkward as shit, and hauling it under the Herc's wing, where the propellers blow their exhaust directly in your face, is really scary. Although admittedly, I might be a few inches too short to actually get decapitated by the spinning razor blades, but god knows I'm not gonna take my chances with this one!
And now we wait. Pumping 3000 gallons of fuel off a Hercules takes quite some time, in which you merely stand on the windy flight deck to wait for the loadmaster's hand signals, and to overlook the situation - a leaky pipe or spill during the procedure can have devastating consequences!
Amundsen-Scott South Pole Station relies on the tanker flights - most our fuel get's here with the overland Traverse, but nowhere near all of it. Now, towards the end of the summer season, we get up to five Hercules full of AN-8 every 24 hours - and my fellow fuelie Justin and I have been working the night shifts in the last couple of weeks. My pocket watch says: Almost 3 in the morning. Sunlight is reflecting off the aircraft's cockpit windows.
"Comms comms, this is fuels: Skier 93 is preparing to taxi. Total gallons received is 2907. Again: 2-9-0-7. Do you copy?"
Finally, the last tanker of the day is successfully defueled and about to depart South Pole Station airfield. Tired and kind of sore I am falling on the couch in the fuel barn - also called the fuel chapel, where we are gonna celebrate the nearing end of the summer fueling season tomorrow. The Tanker Toast is a tradition among the McMurdo fuelies, and was adapted at South Pole as the Tanker Flight Toast - in which the fuels chapel gets doused with Champagne.
I've been a lot more involved in fuels activities than I expected. When I first volunteered for the job, I thought I was gonna marshall the last Herc and test a fuel sample every now and then - and look where I am now! I fueled and defueled over 20 aircrafts, did tank transfers, helped with offloading the Traverse, and became winter fuels team lead! It's a lot of work, but I am incredibly happy about this opportunity - where else in the world would I ever have the chance of doing all that? I love South Pole!
Science facts #4 The IceCube Laboratory
I guess it's about time to talk about my actual job a little bit again. But before I tell you what exactly it is that I do (because I like messing with people who keep asking me that exact question ;)), let me show you my workspace! The IceCube Laboratory, or short ICL, is located in the dark sector* (I know, right?!) about a kilometer away from Amundsen-Scott South Pole Station. It marks the center point of the IceCube detector which is buried under 1.5 km of ice. All the hundreds of miles of cables that IceCube consists of come together in this little building. Those arm-thick cables enter the ICL through the two large cable towers you can see in the picture above, and are split up inside into smaller red quad cables which each are connected to four DOMs deep down in the ice; their other ends are connected to the DOMHubs, custom-made computers that feed high voltage to the sensors and read their data in return. We've got 97 of those! All the other machines (we've got a total of about 200!) are data processing or infrastructure machines, that means they filter and pre-analyse the data, they host important resources like repositories, mail accounts, or the detector monitoring system, or are responsible for the Iridium connection that lets the winterovers communicate with the North during satellite outages.
So yes, the essence of IceCube is housed in the little blue building in the middle of nowhere - it's cozy, and the noise of all the machines has a somewhat soothing effect on me by now. The dog house, the little blue cube on the roof, is a perfect get-away when you need a break from life on station. I'd spend way more time out there, if the ICL would feature a bathroom with running water...
Fun fact: The ICL is THE ONLY building at South Pole that has to be actively cooled. For that purpose the outside air is sucked in, heated up (yes, we're at South Pole), and blown into the server room. If the air conditioning shuts down for only 20 minutes, the exhaust heat of our computers heats the server room up to almost 60° C - which can be fatal for all kinds of expensive equipment in there! That's why we monitor the temperature very closely with dozens of sensors.
* I will explain South Pole's sectors in a later post, promise :)
You thought South Pole was a place most hostile to life in every way? Not at all! After all those McMurdo wildlife pictures I showed you earlier last month, I think it's time now to present what Pole has to offer. Because if you look close enough, you find all kinds of fauna lurking and creeping in and around South Pole Station. This journal entry is dedicated to the creatures that only those with a keen eye can see.
Admittedly, most of the animals found here are most likely not native to South Pole. Allan the sock monkey, for example, is believed to live a nomadic life with the Traverse people. Legend says that the sturgeon in the ice tunnels is originally from Russia, and the creepy monkey in the office obviously crashed its UFO at South Pole at some point. The T-Rex magically showed up this very season, and nobody knows who is behind his sudden appearance (chrmchrrm, Zane). There also is one species that visits South Pole quite frequently, and in contrast to all the other creatures, you don't have to try hard to find it - in fact, sometimes it's really difficult NOT to run into at least one specimen of this kind on your way from the lab to the bathroom: Tourists. They come back every summer season when it apparently gets so hot in the Northern hemisphere, that it's worth about 75 grant to breath ice-cold South Pole air for literally one day. Anyways, occasionally you get to meet a famous person in Amundsen-Scott's hallways (because those are usually the ones with that kind of money).
The story behind the sturgeon in the ice tunnels has as many versions as there are people telling it, and every single one of them is probably true. So far, I think this is what happened: A long, long time ago, the Russian station Vostok located at about 72° South on the Antarctic Plateau, presented the sturgeon to McMurdo station as a gift. The McTownies, suspicious as they are, did not dare to eat it - so it ended up in one of their cold storage buildings where it slept for years and years. But then, one lucky day, a McMurdo supply worker found it and thought it was funny to guard-mail it down to South Pole station in one of the last aircrafts of the season, so that the Polies would not have a chance to send it back. After all those years the poor fish did not meet the galley safety standards any more, so that season's winterovers decided to honor it's endurances with the highest (or lowest) of all graves: A shrine in the ice tunnels.
I want to dedicate this week's journal entry to my IceCube team at the Westfälische Wilhelms-Universität (WWU) in Münster, who helped me so much in fulfilling my dream of going to the South Pole. You guys rock!
Before I came here, I worked on the mDOM, the Multi-PMT Digital Optical Module for the future IceCube-Gen2 experiment, together with the guys from AG Kappes which was newly founded in 2016 and soon developed to be the best work group in the world! Those guys made me the most awesome going-away gift: A calendar with a page for every month I'll be here, each holding a picture of them re-enacting a funny scene from all my favorite movies. Maybe I'll share some of those with you over the next months! :D
Ice facts #9 Skua
skuˑa /'skyo͡oə/, noun: A large brownish predatory seabird related to the gulls, pursuing other birds to make them disgorge fish they have caught. [Google Dictionary]
skuˑa /'skyo͡oə/, noun: An abstract phenomenon describing the donation and repossession of everyday items predominantly on research stations in Antarctica; as well as the site of its implementation. [Poptart's Dictionary of Amusing and Inappropriate American Colloquial]
Or, let me put this differently: If you have stuff you don't want anymore or you have to get rid of excess luggage for your way home, you put it in Skua. Be it an old towel, an open box of Ibuprofen, smelly sportswear or that tacky multicolored chain of Christmas lights that someone installed in your room before you moved in - Skua takes it all. At Amundsen-Scott South Pole Station, Skua is a little shack right outside the side entrance, where people put their old stuff for happy finders to take. And this system works - it works so extraordinarily good, that some bold summer people come down here without any extra clothes of their own, with Skua as their wardrobe for the entire stay.
Skua got its name from the famous Antarctic seabird, which is known for its tendency to 'borrow' food from other animals or unsuspecting residents of McMurdo Station who dare to step outside with a tray full of pizza and Frosty Boy.
I went on a 7-day vacation to McMurdo! Nothing to report, all I did was hanging out in our dorm eating pizza for a week. Also the occasional shower-beer.
... Just kidding! :D
Although I have done the above things in a certainly unhealthy extent, I did go on a bunch of awesome adventures with my South Pole friends Luis, Tony, Ta-Lee and Cherisa; of which I want to narrate in this week's journal entry. R&R stands for Rest and Recuperation and is basically a little beach vacation at the coast of Antarctica granted to everybody who winters at South Pole, as their last chance to see something else than the sterile interiour of Amundsen-Scott South Pole Station and the big white nothingness it sits in. The destination of choice (or not-choice) is McMurdo Station - if you were following my blog for a while, you know I've already spend a couple of days there since it's the transit harbour for everybody on their way to Pole.
McMurdo Station in the summer time has everything you can possibly wish for when you just spent over 2 months at South Pole: A set of equally crazy, but different faces, a sea-level air pressure so you can actually hike without passing out, humidity, fauna, 24/7 pizza, and HUMIDITY. Also your face doesn't hurt when you go outside; the temperatures sometimes reach to a few degrees above freezing here! If you compare the above picture to the one I took in October, you can see that most of the snow in town has made way for a brownish-red combination of dirt and volcano ashes. How refreshing!
Speaking of fauna: There are actual living animals at the coast of Antarctica; and I am not talking about that poor little moth they once found in a box of broccoli. See the photos below for all the species we encountered! :) You might think penguins are a natural thing to be around in Antarctica, but at this time of year, when the sea ice is not completely broken up yet, you actually have to be pretty lucky to see them! So I am particularly proud of the picture on the right: Ta-Lee and I spotted 10 Adelie penguins on the sea ice in Winter Quarters Bay that wandered off pretty soon after we arrived, to mess with the seals you can see chillin' on their lazy butts in the background. For all the winterovers who did not get to see them: Don't be too sad; when penguins walk around on land, they are pretty much just drunk human adults, of which you can find one or two in McMurdo without having to go out to the ice shelf.
Visiting McMurdo is not only worth it for stalking wildlife, though. You can go on plenty of beautfiul hikes in the area - because in contrast to the plain white oblivion of South Pole, the coast has some actual landscape going on. Together with my R&R crew and fellow IceCuber Matt, I ventured to climb the famous mesa of Castle Rock - quite an advanced hike, but the view from up there is so breathtakingly beautiful, it makes you forget that you are sweating and freezing at the same time. Almost six hours full of amazing sceneries (some of which part of some serious bonding experiences) we spent hiking the icy wilderness of Ross Island; quietly shadowed by the magestic Mount Erebus, the southernmost active volcano on Earth.
Wait what? Active volcano?? ... Calm down. Erebus has an open lava lake at its top, which means enough pressure in form of little eruptions is released every now and then to prevent a massive eruption of enough power to wipe out Winter Quarters Bay. So no need to evacuate McMurdo Station any time soon. ;)
McMurdo is a crowded place: Almost 800 people at this time of year (in contrast to about 150 at Pole)! Most of them live in two- or four-bed dorm rooms, which makes it feel a little bit like a school trip (thanks Cherisa for being such an awesome room mate!). Although that's a little scary at first, a big population comes with conveniences like a barber shop, a coffee house, bars, a variety of community activities, even a radio station! R&R people from South Pole seem to be a big hit in McMurdo - we got shout-outs on IceRadio at least four times! DJ Dennis, if you read this: You're awesome! :D If you want to get away from the crowd, Hut Point right outside of town is the spot of choice. Not only does it feature a great view over Winter Quarters Bay, it's also home of Scott's Hut: An exact replica of the shelter that was built for Scott's expedition over a 100 years ago. Most of the exhibits in there are originals!
The ice breaker arrived in McMurdo this week. Very soon, the sea ice will be broken up completely, the bay will be alive with all kinds of sea animals, and the big cargo vessel will dock in McMurdo - the busiest time of the season. I will not be there to witness this; by the time hell breaks loose in McTown, I will be snuggled up in my own cozy, tiny set of walls, at the place I call home now - South Pole.
There is a lot of exciting things going on at South Pole, I learn new things and make new friends every single day. But today, something so breathtakingly beautiful happened that reminded me why I really wanted to come down here in the first place: To watch the sky. Today I got to be the proud witness of a display that reveals itself only once, maybe twice a year, and only at a handful of the coldest of all places around the world.
What you can see in the photos (that I took with my new wide-angle lens that came in with the mail after Christmas) is a combination of rare atmospheric halos, produced by ice crystals in Earth's upper atmosphere that reflect the sunlight in a very special way. Let's dig into this a little bit with the help of a book I found in the meteorology department; Atmospheric Halos by Walter Tape. The most basic sundogs - or parhelia - are formed by plate crystals as shown in the figure above. Although the crystals have very different orientations, the refracted rays of light behind them are nearly parallel, so that we see a concentration of light in the opposite direction. The more fancy halos are formed in a similar way by differently shaped crystals. The photos I took show two parhelia, a 22 ° and 46 ° halo, the upper tangent arc, the supralateral and circumzenith arcs, infralateral arcs and my favorite, the parthelic circle, which at one point during the show went aaaaall the way around the sky. Crucial for this kind of display is the number and size of the ice crystals, their orientation and alignment, and the density of the crystal cloud. All these factors have to work together perfectly - that's why these halos are so incredibly rare!
In order to take decent photographs of such solar phenomenons, you need to block off the sun itself - otherwise its brightness would overshine everything else. In my case, I used human sunblocks which turned out to work pretty well ;).
Information and drawings taken from:
 Walter Tape: Atmospheric Halos, American Geophysical Union, Washington D.C., 1994.
If you know me, you know my love for science and the joy I find in explaining things (which I tried above). And I don't think science diminishes the beauty of the moment at all - but this day again reminded me to take off science's safety goggles every once in a while, and to just sit there unspoiled, watch, and humbly appreciate the rare moments mother nature shares such gems with her children.
The turn of the year is kinda arbitrary here, since all time zones of Earth come together at South Pole. Nonetheless, since Amundsen-Scott South Pole Station runs on New Zealand time, we celebrate New Year's Eve at UTC +13. Yes, we are a day ahead of most of you guys!
New Year's Eve party was held in the big gym. No need to go outside, since we are not allowed to burn any fireworks (which would probably not be very impressive in bright sunlight anyway). You think New Year's is boring without burning or melting stuff? Not at all! Two very special guests made an appearance that totally made up for not being able to play with flammables. One is the ancient, all-knowing Trotterdamus, who would tell you your 2018 fortune at almost no cost (but your soul, dohh). The other is the mysterious inflatable T-Rex, who makes unpredictable appearances every once in a while - no one knows when and where it will happen, and no one knows who he is in the real world. Some things are just meant to remain a mystery forever.
South Pole Station is built on a gigantic glacier, which sloooowy makes its way towards the coast of Antarctica - about a couple of meters every year. That means it is moving away from the geographic South Pole inch by inch. As demanded by yearlong tradition, the geographic South Pole marker is relocated to it's new position relative to the station every January 1st. This is done in a big ceremony to which everybody is invited - not only station population, but everyone on site; including tourists camping out in the nearby tourist camp. The marker is not only moved, but also replaced by a new design every year. Martin Wolf, one of last season's IceCube winterovers, came up with this year's design, and it's pretty awesome!
Ice facts #8 South Pole markers
There are two South Pole markers near Amundsen Scott South Pole Station. One is the ceremonial Pole marker, which moves along with the glacier and therefore remains at it's place relative to the station at all times. It is surrounded by 12 flags representing the founding members of the Antarctic Treaty: South Africa, Belgium, Japan, France, the United Kingdom, the USA, Norway, New Zealand, Russia, Chile, Australia, and Argentina. Since it is the sexier of the two Pole markers, it is more commonly seen in pictures. The other marker, as you've probably correctly guessed, is the geographic South Pole marker, which marks the actual geographic South Pole. Since the glacier moves away beneath it, its position has to be re-calculated every year. The marker is replaced by a new design and moved to its new location every January 1st in a big ceremony. The old marker goes into a little marker museum here on station, where it remains for all future generations of Polies to see. Usually, all winterovers sign their season's marker, so that their names remain a part of South Pole forever.
Both markers used to be right next to each other; but due to the constant moving of the ice cap, their current distance is about a 100 m.
"Attention South Pole Station, attention South Pole Station! This is Comms wishing everybody a Merry Christmas!"
Yes, it's Christmas at South Pole! I can't believe I have been here for 55 days now - the weeks go by so fast when you are having the time of your life. Here's a little bit on how to celebrate the southernmost Christmas in the world: First of all, a white Christmas is not a thing to be worried about here. Also I can say with at least 100% certainty that Easter, Halloween and my birthday will be white, too! On the other hand, we are missing a bunch of other christmassy things here; like candles (fire hazard), open fire places (guess what hazard), real Christmas trees (contamination hazard), and a relaxed attitude towards eating raw cookie dough (after being publicly shamed for cross-contaminating the gluten-free cookie dough with the dairy-free ginger bread cookie cutter, they made me stand in the corner where I had nothing else to do but snitching dough, so they eventually kicked me out of the galley. Pff). However, the one thing everybody, including myself, is missing the most around this time of year is their families and loved ones. I love you Mom & Dad (I promise to watch "Little Lord Fauntleroy" while getting drunk on Glüwein on the sofa like we always do :))!
South Pole population has it's own little old and new traditions, though. Besides an A-MAZ-ING Christmas Eve dinner, we sang carols in Comms with McMurdo station, Shackleton field camp and WAIS Divide field camp over radio. We even had a little handmade-Secret-Santa ("Wichteln" for my German-speaking friends) going on! The ARFF (Aircraft Rescue and Firefighting) guys organised a little afternoon-Christmas party for us on the 23th (pardon me, 23rd), and we had another one in the gym on the 24th. In the middle of the night before Christmas, someone had the glorious idea to transform the big pile of snowdrift behind the station into a gigantic sledding slope. It was actually a lot steeper than it looks on the pictures; it's a Christmas miracle that nobody NPQ'd (aka physically disqualified themselves from the program) that night...
Another highlight of Christmas celebrations at South Pole is the "Race around the World": 2.27 miles across all time zones of Earth, be it on foot, with skies, in a handcrafted cardboard sled, in a pink bunny costume on a unicycle or on top the party-barge towed by a bulldozer - everybody can participate. Only the runners are competing though; and the price for the fastest male and female finisher were 10 extra shower minutes to use at their convenience (not necessarily together)! Stupidest Christmas present ever, you think? Well, if you live at a place where you're allowed to take two two-minute showers per week only (to save water and energy), shower minutes pretty quickly develop to be the new inofficial currency, which can be traded for all kinds of candy on the South Pole black market. And now guess who won the race as South Pole's fastest woman? :)
With this in mind, I wish all of you a jolly little holiday time. For my friends and family at home: I've never missed you more than now at the Christmas holidays; reminding me of the coziness and comfort of your company. But know that I have found a new makeshift little family here at South Pole, consisting of wonderful and amazing people I can count on at all times, and who are there for me whenever I get homesick. I love you guys! Merry Christmas.
PS: So far I have charged my cellphone twice since I got here. TWICE. No kidding.
Ice facts #7 South Pole weather
Gather 'round folks, it's time to talk about the weather. Well, actually there's not much to say except that it's cold as f*ck. Anyway, here we differentiate between two different kinds of cold-as-f*ck: The actual temperature and the windchill. The first one tells the temperature as it is taken by the outside thermometers; the latter tells you how it actually feels like when you go outside and stand in the wind. Those two can have veeeery different values sometimes! In summer, the (actual) temperature does not climb higher than -20 °C; in winter, it can drop down to almost -80 °C! The daily weather board, one of which you can see below, also tells you the current "experienced" altitude calculated from the air pressure. This sometimes goes up to 10,800 ft, compared to the "actual" 9,301 ft. And believe me, you can really feel the difference when working out in the gym and the extra air you need is JUST NOT THERE. Phew.
The humidity at South Pole is absolute 0 - always, everywhere. Except in the greenhouse and sometimes the sauna, which makes these rooms very frequently visited places on station. Some people, including me, have their own humidifiers in their rooms, but due to the constantly running air conditioning they don't work really well except when you seal your vents shut (which you are very much not supposed to) or let the humidifier blow directly in your face when you're asleep. It sometimes helps to air-dry your laundry on the clothesline in your room - it will drip dry in notime and adds a little bit of water to the air for at least a few hours.
Man, am I glad I brought my big bear mittens with me! With one hand I am shielding my face from the ice cold wind, with the other I try to keep the camera warm that is sitting in it's case on my lab. The snowmobile is speeding with 30 miles an hour through the icy desert that lies beyond the perimeter of South Pole Station. The ARA (Askaryan Radio Array) drill camp is out here - and that is where I am going today.
It is a long snowmobile ride, almost 25 minutes - especially when the wind is blowing like it is today. I can see the camp in the distance, although I can barely make out a couple of rectangular shapes that are reflecting the sunlight near the horizon. The way to the camp is marked by green flags every 50 meters; I am watching them fly by one by one as I am pushing my snowmobile to its limits. It's a ton of fun, but the faster you go, the more unforgiving is the airstream that painfully reminds you of every single exposed millimeter of your skin.
Having reached the camp around 9 in the morning, I am welcomed by the drillers who already have been out here for hours. I am just in time to witness the genesis of a new ARA hole - the hot-water drill head is ready to carve it's way 200 meters deep into the Antarctic ice cap. I am not here to help with drilling though, but with deploying the first ARA string at this drill site, which is also super interesting - and most of all warm, because they set up a little shack around the hole that has already been completed earlier this week. The little hut is pretty packed with us six people, and I am trying my very best not to stand in the way and being as ingenious as possible. It's a big honor for me to be here - Since I wasn't there for IceCube drilling back in the construction days, the ARA people were so nice to let me come out here today to have a look and help out a little. Very slowly the ARA string is lowered into the icy darkness beneath our feet. Four very sensitive radio antennas are about to be buried forever - together with one or two sharpies that someone might have accidentally dropped into the hole. Totally not my fault.
Lucky as I am, ARA is not the only super-exciting thing I got to witness today. In the pictures above you can see the awesome cloud formation I spotted on my way back to station. It almost looks like snow is falling at South Pole! I showed these pictures to the meteorology department - according to them, snow showers are not supposed to happen here ever, but they could not come up with a better explanation for the phenomenon. A Christmas miracle!
Science facts #3 Askaryan Radio Array (ARA)
The Askaryan Radio Arrary ... pardon me, the Askaryan Radio ARRAY is a sister project of IceCube. Like the Cube, it is also looking for high energy Neutrinos, but instead of optical sensors it utilizes radio antennas to detect our favorite particles. The measurement principle of ARA is based upon the Askaryan effect, which describes the generation of charge anisotropies in bulk media (such as ice) caused by high-energy neutrino induced particle cascades. The anisotropy emits coherent radio waves which can be detected by the ARA antennas.
At the end of this summer season, the experiment will consist of six stations with four holes each, where every hole is holding 4 antennas. Once completed, ARA will cover an area far bigger than IceCube, although with a far smaller detector density. It's neutrino detection sweetspot is at energies even higher than IceCube's, which makes it an important addition to the South Pole Neutrino Club.
Sometimes even I need a break from everything, so today I ventured out to the berms - a huge, mysterious area near station where all the forgotten and lost things of Antarctica end up. It stretches out for miles - and it's the only place at South Pole where you can ever truly be alone.
If you take a close enough look, you find all kinds of interesting items out here, most of them half or completely buried beneath the snow. And if you're not careful, you will find yourself in one of the many crevasses that open up between pieces of furniture, cable spools, Christmas trees and scrap metal, and you will eventually become a forgotten piece of South Pole history as well. Luckily, this tragic fate passed me by, so I could continue my lone Sunday afternoon roam through this peaceful, yet nostalgic little world of its own. Whenever things trouble me or I am feeling sad, I come out here to regain perspective. It reminds me where I am: South Pole, the bottom of the world.
A lot of people that follow my blog requested images of station interior - and I take fan mail very seriously! So today's journal entry is about one of the most important places inside Amundsen-Scott South Pole station: The power plant.
Normally, people are not allowed in the power plant unless they are staff or have some serious business to do there - and my business is pretty serious! As a member of South Pole Station fire brigade, I need to know every last corner of the station in my sleep, especially the power plant as a fire-hazardous area. So Rob, our fire brigade team lead, gave us a tour: South Pole Station entirely depends on jet fuel which is brought here by plane and the South Pole Traverses. Below you can see the "fuel bladders" that are towed all the way from McMurdo to South Pole on a sled! At Pole, the fuel is stored in gigantic cylinders in the fuel arch, and converted into power and heat by four bigass yellow engines. Those are supposed not to catch on fire - but IF shit would hit the fan, there is an emergency power plant on the other side of the station, which could keep the winterovers alive for the rest of the year. Let's hope that won't be necessary...
Speaking of fuel: Since last week, I am a proud member of the winterover fuelie team! Together with Rob, who is also one of our research associates (RAs) besides fire team lead, and Justin, our facilities engineer, I am responsible for fueling the last plane that leaves Pole (because the summer fuelies will be on it), and the first plane that gets here next year. The job also includes testing our fuel for sediments and water; it might get used to refuel some of the aircrafts during the summer. The most awesome part of the job though: Marshalling the last Herc. Isn't that exciting?! I've been studying marshalling signs all month! :)
Ice facts #6 The South Pole Traverse
Imagine a caravane in a desert - but instead of camels, you've got heavy bigass bulldozers; instead of tents, you've got containers on gigantic sleds; and instead of sand, you've got ice as far as the eyes can see. That's the South Pole Traverse. Three times a summer season, 10 intrepid heroes go on this incredible journey, towing fuel bladders all the way from McMurdo to South Pole to provide the station with liquid power for the winter.
There obviously is no paved road to Pole - so the Traverse has to make its way through more than 1600 km of ice and snow. The first vehicle in the caravane carries a ground-penetrating radar (GPR) to detect the many crevasses in the glacier, which can be fatal to mission and life.
The journey of the Traverse takes about three weeks with 12 hours of driving every day. Our 10 heroes have to spent their leisure time in very close quarters: There is a cargo-container sized module for sleeping, and another one that servers as kitchen and bathroom.
Okay okay, I'm up! What is it now? Does baby need a diaper change? In fact it does, except that the baby is IceCube, and the diaper is some part of its system that misbehaves. And if IceCube becomes very unhappy, it wakes up one of its winterovers over the radio to get some attention. And tonight is my turn. At a place that has brightest sunlight 24 hours a day, it's sometimes hard to tell the time by peaking through a window. But you can tell by the people you meet in the hallways. At night, the normally very busy station is fairly quiet, and the only people I run into are our breakfast chef Denise, and Josh, one of our satellite engineers, who is getting his first coffee of the work day. Having reached the B2 lab, I can quickly identify tonight's problem as a crash of the Data Processing and Filtering (PnF) system. This happens quite frequently, so I know exactly what to do. Nonetheless, I sit by my computer for a while to wait till baby IceCube calms down slowly.
Yes, that's right - As an IceCube winterover, you work whenever IceCube needs you, be it in the middle of the night or in the middle of your bi-weekly two-minute shower. Johannes and I work in alternating 7-day shifts, in which we have to pay very close attention to our radios in case IceCube gives us an emergency call.
Even though my ongoing shift has been extremely page-intensive so far, I am still having a blast at South Pole - especially now that I have officially celebrated my first Thanksgiving ever! I learned that nowadays, this American holiday is mostly about food, of which I had plenty - and vegetarian turkey really can be super tasty! The galley staff does an absolutely amazing job to keep us all happy.
A not-so-busy week at South Pole! It's my third week here, and we already set a new absolute record-low of air crafts arriving. We only had four planes so far, all of them in my first week - basically every department on station is behind schedule now, either waiting for people or cargo or both to finally arrive at Pole. There is a ton of summer workers sitting in McMurdo who already hit their RETURN date from Pole without having been able to even get here.
On Sunday, we finally got an aircraft coming in - unfortunately one that wasn't going to land here. The conditions only allowed for the annual air drop, which means a big C-17, or Globemaster, approaching station, circling above for a couple of times, then dropping some cargo near station site, and returns to Christchurch, leaving behind a hand full of crying still-on-station 2017 winterovers - or leftovers, how they are nowadays called - who desperately want to get out of here.
Since work for most departments here is basically frozen (chrchr) until cargo arrives, the station population killed their time with allerlei Unfug; e.g. sliding down the snow drifts on kitchen equipment (see picture below) or telling comforting lies about the weather situation to the leftovers.
After another week of anxiously watching the weather forecasts and listening to Comms announcements about flight updates, we finally, FINALLY got a Hercules coming in today, which was a big relief for almost everybody on station, especially the leftovers. I am a little sad they're leaving though, I really got to like them despite their tetchyness about being stuck here. But I guess I have to accept the sad truth that everybody has to leave South Pole at some point. ;) My boss Ralf also arrived on the Hercules, which means we finally can get started on IceCube summer upgrades!
Ice facts #5 South Pole air crafts
South Pole aviation is a particularly tricky business. A mission's success depends on many different factors - mostly weather, which is pretty much unpredictable in McMurdo, at Pole and in between. For a plane to fly, the weather has to be just perfect. It can changes within minutes though, and it happens quite frequently that planes take off in McMurdo, fly all the way Pole just to discover that the weather has changed so severely that they aren't able to land safely, and fly all the way back. This is called "boomeranging".
There are four planes to fly missions to Pole: Most cargo and people come in on a LC-130 or Hercules, the biggest ski-equipped air craft to land here. Backup missions are flown in the much smaller Baslers. Their cabin is not pressurized, so they have to fly very low, which means you get a beautiful view of Antarctica! The tiniest planes to fly to Pole are the Twinotters. Tourists or important people often arrive in those. Their engines are small enough to be heated up externally, so they can actually be parked at Pole for several days - in contrast to the Hercules machines, whose engines have to run the whole time they're here. The by far biggest Antarctic air crafts are the C-17s or Globemasters. Those are not equipped with skies and are way too heavy to land on the snowy South Pole ski way, so they are used to get people from Christchurch to McMurdo's Phoenix air field, which is located on the ice shelf and can carry more load, until it melts in the summer. The annual South Pole air drop is also flown by these gigantic machines, because it does not require landing.
Fun fact: For each of the South Pole air crafts, there is a server with the same name in ICL! Globemaster takes care of syslog and serves as an NSF mount, hercules hosts the IceCube wiki and SVN, basler is our backup server and twinotter is home of our monitoring system.
"Attention South Pole Station, attention South Pole Station!"
My well-deserved sleep is being ended abruptly by the announcement over the radio.
"Flight SK-21 from McMurdo is canceled. I repeat: Flight SK-21 from McMurdo is CANCELED."
Listening closely, I can hear a mumbled expression of disappointment rolling through South Pole Station. The radio all-call that just woke me up is not unfamiliar at all: It means that today's flight from McMurdo to South Pole Station is canceled again - like all the flights in the last week. It also means that no cargo and no new summer workers are coming in today, and, most importantly, no winterovers of last season can get out. There is still a handfull of them on station, and being delayed over and over again has made them a little tetchy. Most of them are missing out on their well-deserved vacations, others are just understandably fed up with being stuck here. I may or may not be in their situation in a year from now; but so far, every day here is another day in paradise for me!
My IceCube driver seat duties still leave me enough time to explore the station and see what everybody else is doing. This week's mission: Annoy the weather people! The meteorology department is in the B2 lab, right next to my own workplace. So from time to time I go over there, visit my new friends JJ and Janelle to see what they're up to. If you get on their nerves long enough, they let you launch one of their weather balloons (see picture to the right)! :)
Science facts #2 IceTop Snow Measurements
If you paid attention in my IceCube facts #1, you might have noticed that IceCube does not only have in-ice optical sensors to measure the neutrinos, but also features some modules right beneath the surface - these are called IceTop stations. Each of the 86 strings that are deployed in the ice has one of them on top. All together, the IceTop stations are used to measure lower-energy neutrinos, and they also serve as a veto-mechanism for the in-ice DOMs. The problem with stuff that is set up at the surface of South Pole ice plateau: It does not stay at the surface for very long. Things are being burried in snow drift faster than you can say "penguin". Since the amount of snow that covers IceTop has an affect on the measurements, every once in a while the IceCube winterovers have to go out and estimate the snow level on every single IceTop station. This can be a long and cold adventure, depending on the windchill and how many people can be motivated to help. Fortunately, the old winterovers Martin and James were still here (they belong to the handfull of toasty people who are still waiting for a plane to take them back to the real world) to help Johannes and me, so it took us only two afternoons.
ICL, the IceCube Lab, is located about a kilometer North from Amundsen-Scott South Pole Station - which is quite a walk, considering you have to wear your whole ECW (Extreme Cold Weather) gear, you are walking on snow, and icy wind might be blowing in your face depending on which direction you walk. So yeah, this is very much not a walk in the park, especially when you are being an idiot - like myself - and take off your outer-layer-mittens in -60 °C windchill for a few seconds to adjust your neck gaiter. Once your hands are cold, in this environment there is no way of getting them warm again with pure blood circulation. I had to walk back the whole way from ICL thinking my hands would gonna fall off (which is a legit reason for NPQ btw). The bad thing: It hurts even more once you're back on station and they start getting warm again. Seriously, that's incredibly painful. Luckily it turned out to not be a real frostbite quite yet. Lesson learned.
Despite this frosty experience, I have been very much enjoying every minute of life on Amundsen-Scott South Pole Station so far, even though I was not able to sleep yet, most likely because of my altitude symptoms and because I am just too excited to be here. This is so very much the right place on earth for me that I am already considering coming back. The station is all neat and clean, the food is amazing, and I feel very much at home. They assigned me a windowless room at first which I was quite unhappy about, but luckily one of my co-Winterovers switched rooms with me - apparently there are people who do not like 24 hours of sunlight in their room ;).
Martin and James, the last season's IceCube winterovers, are turning their duties over to us during the next two weeks. We are taking it easy though while we are still adjusting to the elevation. So there is some free time to kill, which I sometimes spend helping out my new friend Grant in the dishpit - I like it there, and the community very much appreciates people who pitch in, which gives me my daily dose of good-deed-afterglow :)
Ice facts #4 ECW
ECWG stands for Extreme Cold Weather Gear and includes all kinds of clothes to protect you from South Pole's harsh environment. The most important ECW item is the "Big Red": The red Canada goose parka which does a perfect job to shield you from the wind and cold, has a trizillian pockets to store (and loose) all your stuff in, and even has your name printed on it so that people know who you are when they meet you outside and are not yet familiarized with the way you walk ;) Then, of course, there are the "Bunny Boots": Big white boots made out of rubber to keep the warm air inside and isolate your feet from the icy ground they are walking on. All your ECW comes in big orange bags which further contain three kinds of mittens, a neck gaiter, a hat, goggles, wind-shield pants, and a bunch of other stuff. Everything that's in there has to be returned upon your re-deployment to the real world.
South Pole. I made it to South Pole. The dream is real! This is the happiest day of my life. I can not find enough words to describe how breathtakingly beautiful this place is. I am still overwhelmed by happieness, astonishment and all the new impressions that are flooding my brain right now, it almost feels like flying. ... Or, well, I could still be suffering from altitude sickness which has about the same effect; I feel about 20 lbs lighter and the station seems to move around a little like on a boat. I felt it very heavy the first day, and of course you are supposed to take it seriously, but I actually kinda liked it ;).
The temperature at Pole is a negative 45 °C right now (that's kinda chilly). The sun is high up in the sky as it will be for the next months. The picture you can see above is taken around 10 pm. Settling in on station, being handed over my new job and processing all the amazing stuff that is happening on top of that keeps me very busy, but you will hear from me shortly!
My stomach begins to feel funny as the pilot starts to accelerate the big C-17 "globemaster" airplane on the runway. Without my earplugs, the noise of the engine is almost unbearable. I can not see what is going on, because we are strapped to our jumper seats on both sides of the cargo hold, facing big containers between us. From here, it is impossible to see through one of the few tiny circular windows. It takes almost forever until the massive structure of steel and khaki has gained enough speed to finally take off - on its way to Antarctica!
Flying in a C-17 is an adventure by itself. No commercial airline flies to Antarctica, so you get to fly with one of these badass military planes of the American Air Force - not exactly the most comfortable experience in the world, but definitely exciting!
Almost everybody who is on transit to South Pole has to go through McMurdo station. It is the biggest of the Antarctic stations; in summer it can hold up to 1200 people. I only spent one night here, so I did not get to see all the facilities except my quarters, the galley and both bars. The gateway to South Pole is William's airfield, which is located about 30 minutes away from McMurdo station by "Ivan the Terra Bus", a terribly slow vehicle that used to shuttle passengers in McMurdo for generations. People get to wait around at the airfield a lot, because it happens quite occasionally that flights get canceled at last minute due to bad weather in McMurdo, at South Pole or in between - luckily, we were able to take off after about 2 hours. The big C-17s can not land on the snowy skiway at South Pole, so the aircrafts flying the primary missions to the bottom of the world are the LC-130s, aka "hercules". They are smaller, lighter and equipped with skis instead of wheels.
"IC to Team Alpha: Report your situation!" "Team Alpha to -bbrrzzz IC: Large fire ... second floor of B building - brrzzzzzzz zz of smoke ... one person missing. I repeat: One person missing. Requesting backup. Over -brrzzzzz." "IC copies. Sending in Team Bravo."
But there's no time waiting for Team Bravo. The visibility is literally zero, black smoke everywhere. With one hand I feel the ground in front of me, my other hand is sliding the wall; slowly crawling forward inch by inch. My team mate is crawling behind me, carefully following the dim glow of my oxygen tank. Suddenly my hand runs into something that feels like a human foot - the missing person is unconsciously leaning against the wall in front of me! Screaming our encounter over the coms system, I make a desperate attempt to tie my rope around the victim's chest, in pitch black darkness and with heavy fire fighter's gloves on my hands. Icecold sweat runs down my face as the regulator on my SCBA mask starts vibrating - an indicator for my tank being almost empty. "I am low on air - let's get him the f*ck out of here!"
When we finally close the door of the smoky corridor in building B behind us, both my team mate and me rip off our SCBA masks to inhale a chunk of fresh air. Sean, the fire chief of the Aurora Public Safety Training Center, declares the scenario successful - what a relief! As we check on the victim, he is not breathing - which is probably because he does not have a head. And is made out of lead and plastic. He's also not wearing clothes, but that's a whole different story.
You're wondering what is going on? Fire fighter training in Denver, CO is going on! Since there will be no professional fire fighters on South Pole station during winter, a certain amount of people has to be trained accordingly; to become the southernmost fire brigade on earth! Juan, Sean and Jessie are the three professional fire fighters who's lucky job it is to get us in shape - us, a mixed bunch of scientists, technicians, cooks, plumbers, electricians, machinists. We all met each other just this week, and now we are supposed to fight fires together. Exciting!
Becoming a fire fighter is tough. The full gear, including helmet, hood, coat, pants, boots, gloves and air pack, weighs almost 30 kg. They make us crawl through mazes, fully bunkered up, in complete darkness and while breathing off a tank. I am actually pretty good at the maze because I am tiny, with a record time of 5:15 minutes! What I am not good at is dragging unconscious people around, let alone up a flight of stairs. I have a hard enough time carrying my own extra weight of gear! Every night I get home with sore muscles, dirty clothes and outright utterly exhausted. At this point I want to acknowledge my sister Claudia, who happens to be an actual professional fire fighter: You are my hero! :) Despite the physical inconveniences the fire training might bring along, I am having the time of my life right now. If you ever get the chance to winter at Pole, sign up for fire training - trust me, that's what you want. Not only because the lieutenant is really cute.
One last thing: It never gets old to see people in full gear wiggling their butts to prevent their fire-fighter-is-not-moving-alarm-device from going off all the time... :D
For my German-speaking friends:
Herzliche Einladung zum Astroseminar der Uni Münster! Als alter winterover-Hase wird mein Kumpel Emanuel dieses Jahr einen Vortrag mit dem Titel "Von Neutrinos und Erdbeeren am Südpol" über sein Jahr in der Eiswüste halten. Dazu gibt es wie immer jede Menge andere spannende Vorträge rund um das Thema Astrophysik; eingeladen ist jeder, der Bock drauf hat (kein Physik-Vorwissen erforderlich).
The most important lesson I learned in the last couple of months: NEVER provoke your own luck at the airport with a carelessly spoken jings. "I never lost a bag at the airport before" is NOT a smart thing to say when baggage claim is about to start. So yeah, my vacation started with a couple of hours of unintended idle time at the airport, in which I was waiting for my luggage that apparently decided to board a different plane than myself. Anyway, in the end I was happily reunited with my bag, my boyfriend Simon and my parents at exit 5 of Düsseldorf airport, ready for my 10-days of home vacation.
These 10 days unfortunately went by in notime. I tried to spend as much quality time with Simon and my friends as possible, visit all my favorite Münster bars and restaurants, have a little coffee party with the guys from AG Kappes - my workgroup at the Münster physics department - and I even had another little going-away party just for my family! I have not yet fully realized I won't be seeing those folks for over a year. I am afraid that's about to hit me very soon... Luckily Simon made me the most awesome going-away present: A virtual 360 °Cpanorama tour of all my favorite places in the "real world". This is where I will be going when I become homesick.
Ice facts #3 Packing for Pole
So how does a winterover's packing list look like? First of all, you need a year's supply of EVERYTHING. This is more difficult than it sounds - or do you know exactly how much toothpaste you use up in 13 months? Or what kind of medication you might need? You can not just pack everything "just in case", since every winterover has a total baggage allowance of 46 kg. Next to toiletries and all that everyday stuff, you need things that keep you entertained. I packed a shitload of yarn - maybe by the end of winter everybody on station will have a silly handmade sweater they didn't ask for! :D The more nostalgic winterovers also should pack a buncha' photographs of their loved ones - there's no seeing them in a looooong time.
The most expensive and spacially demanding items in a winterover's bag: Warm clothes. Lot's of it. That includes heavy socks, hats, scarfs, balaclavas and long underwear. And of course you want the fancy Merino stuff, so plan on spending quite some money (for what I know it's worth every penny though; I got to try some of it during some cold Madison days already). And that's only the base layer of what you will be wearing at Pole. The ECW (Extreme Cold Weather) gear will luckily be issued to you right before you go - you have to give it back upon re-deployment when your year is over though.
The good thing is: During the austral summer, people can send you stuff. So if you forgot to pack your underpants, it's not the end of the world - at least not if you notice before the end of summer ;)
The electric screwdriver utters a tiny bzzzzzzzd, as I affix the last bolt into the heavy lid of the IceCube cargo crate. I am now sitting on top of two metric tons of shit-expensive technical IceCube gear! Packing up all that stuff was a lot of fun - unpacking it at Pole in freezing -30 °C at an elevation of almost 3000 m: Probably not so much. The crate will leave for Pole this week, but will arrive about three weeks later than ourselves 'round the end of November.
While we've been busy packing up the crate, summer has returned to the city of Madison. As we step outside, we get struck by 30 °C and the mid-Wisconsin typical oppressive humidity. Time for a swim in lake Mendota! The water is pleasantly cool and so crystal clear that I can see the giant carps swimming around my feet. I close my eyes for a second to enjoy the moment... until suddenly someone nearby fires up a lawn mower the size of a pickup truck. Besides the fact you can't buy decent bread here, the one thing that bugs me about Madison is the CONSTANT NOISE. The lawn around the Capitol gets mowed daily (no kidding), and as soon as the mowers are gone, leaf blowers shovel fallen foliage from one pile to another and back again for several hours. There are always truck engines running everywhere, and the few seconds in between all of this are filled with the sirens of an ambulance. But yeah, this really is complaining at the highest possible level - but sometimes I forget how privileged I get to be for the awesome job I have in this amazing city, and for the kickass company of my WO buddy Johannes.
Although winterover training has been getting tougher since the focus shifted from hardware to software, there still is enough time to explore the wild Midwest of America. The wildest thing we encountered so far is the "original Chicago deep dish pizza" - a 2 mm thin pizza crust topped with marinara sauce and 4 cm (!) of cheese. Yes, really. There are no regrets.
The sun does not always shine over Madison. In fact, it has been getting quite autumnal around here lately. A perfect opportunity to to get a little exercise in handling my new camera! Trust me though, for a fully-trained perfectionist like me it's not easy to pick up a new hobby just like that. But with a little help from all-time photography expert Johannes, I do manage to take a not-so-bad picture from time to time. My new favorite Madison photograph is also quite a luckshot I guess:
Ice facts #2 WO training
Here's to all the people who keep asking me: "Are you getting locked in freezers a lot for winterover training?" The answer is: No. We have giant freezers here, but those are for DOM (Digital Optical Module) testing rather than for winterover natural selection. But luckily, deep-freezing winterover trainees still SEEMS to have a certain fascination on some WIPAC scientists, so I get to try the freezers out from time to time - and -40 °C is really not as bad as I thought. Until the cold starts creeping up your pants and sleeves. Then it's bad.
So what AM I doing all day? There is a lot of things winterover-to-bes have to learn before being released to the ice. They have to know the IT infrastructure of IceCube like the back of their hands - every single server and switch, all the power supplies, each cable. Ralf has us stripping down each machine to its pieces and putting it back together again - not in the actual IceCube data center obviously, but at the SPTS, the South Pole Test System. That means most of our time we spend between SPTS server racks. It's noisy, but also full of exciting sophisticated technical Schnickschnack! :)
Another winterover trainee task is to load the big IceCube cargo crate, which leaves for South Pole mid September. So far, we packed it up with roughly 1.5 metric tons of UPS batteries and spare hard drives - almost good to go!
Life as a winterover trainee is no walk in the park - except when it is.
Last week, Johannes and I were roaming the State Capitol front yard, when suddenly we found ourselves in the middle of the Madison Outreach Pride Parade. Shiny clothes, rainbow flags, candy-coloured wigs and lots of exposed skin everywhere. Once we made our way through the marching bands and dancing people, we decided to get some pizza and enjoy the show from a distance - equipped with our cameras. I managed to catch the scenery in my favorite Madison-photograph so far - I decided to go with monochrome for this one, because the vivid colours would blind you for the true beauty of this moment.
For my 27th birthday, we enjoyed a couple of beers at the Union Terrace with Sarah and Khan, two other researchers from Germany we met in our VISA orientation class. We went to something called "Dane Dances" - and holy cannoli, when it comes to open air disco, the Madison folks are ON FIRE! Speaking of beers, Madison has quite a selection of local brews. Take a look at the picture below, maybe you can figure out why I chose that particular one ;)
The first two weeks of winterover Training have gone by in notime, and I have been very much enjoying every little piece of it so far. Well that's not entirely true, there were some organisational issues to get over with (like getting an American bank account, American Health insurance, a VISA orientation class, all of which came with a load full of paperwork. And let me tell you, getting an American Social Security Number is particularly nasty ;)). But apart from that, it's a lot of fun. Everyone here at WIPAC (Wisconsin Particle Astrophysics Center) is excited to work with us, which makes me feel at home already. Besides, Johannes and I get along great, and I have no doubt we will make a good winterover team.
Having used the words "IceCube" and "Winterover" a lot already, I figured this second entry of my journal might be a good opportunity to explain a little (see below). I will try to drop an IceCube or winterover fact every once in a while throughout my journal, so if you think I'm boring you might at least learn something ;).
Science facts #1 The IceCube detector
The IceCube South Pole Neutrino Observatory is a huge particle detector burried in the almost 3000 m thick Antarctic ice sheet at South Pole. IceCube is looking for ultra-high-energy neutrinos. Upon colliding with the atoms of the ice, these tiny particles produce a little flash of blue light. This is called the "Cherenkov effect". The light can be seen by IceCube's thousands of optical sensors, which have been deployed on long chains by drilling deep holes in the ice. The data collected by these sensors is sent to the surface, where it is recorded and forwarded to the Northern hemisphere for analysis.
To get a better idea of IceCube, you can have a look at the picture below (courtesy of the IceCube collaboration) or visit icecube.wisc.edu.
Ice facts #1 South Pole seasons
South Pole works a little differently than what we are used to. There only is one long day (the austral summer) in which the sun never sets, and one long night (the austral winter) in which it never rises. Most people at South Pole only work there in the summer. However, there are a handful of crazy people called winterovers, who stay at South Pole station all year long. This is a demanding and also dangerous job for many reasons. During the long Antarctic night, there is no way of leaving Pole (because the weather is too bad and too cold for planes to land). There is limited internet and NO FREAKIN SUNLIGHT.
Every year, IceCube sends two winterovers who stay at Pole for 13 months. Their job is to keep the detector running at all time.
"Passengers BUSSE and WERTHEBACH, please report to the Delta personnel at gate A75!"
The announcement echoes from the marble walls of the airport toilet. That's me! I rush outside, where Johannes, my workmate for the upcoming 16 months, is waiting for me, already having grabbed our bags to follow the tinny instructions. It's not late at all, so what could they possibly want from us? Could they have mistaken the electronics kit in my luggage for a dangerous device? Am I being arrested?? "Congratulations, Ms. Busse, Mr. Werthebach. You have been upgraded to our Delta Business Class!" says the lady at the Delta desk to us, smiling over both ears. Phew. Not what I had expected. Well I call that a fabulous start to my dreamjob!
After having enjoyed the comforts of a nine-hour overbooked flight to the very fullest (including a bed, free socks, cocktails and a gourmet lunch), we set foot to the lobby area of Madison Wisconsin airport, slightly hungover. Our supervisor Ralf is waiting for us. Both Johannes and I have been here before, when we were being interviewed in April for the very job we will start tomorrow. So Ralf's baseball cap already looks quite familiar to us, which makes him easy to spot in the crowd.
After grabbing some dinner in the "Great Dane", Ralf drops us off at our hotel. I am tired despite my ridiculously comfortable flight experience, so I drop into bed right away. The nightly glow of the State Capitol falls into my hotel room window, making sure everybody gets their well deserved slumber.
