I am currently working in Antarctica at the USA's smallest outpost, Palmer Station. AMA.
There have been a couple other AMA threads out there, but most were in the past tense, and all were from the "other" side of the continent, people working at the relatively large station of McMurdo, which can hold well over a thousand people. So I figure I'd give people some perspective from this side.
I'm currently working at Palmer Station, which is ~700 miles south of Chile and has a maximum capacity of just 44 people (we have 26 here currently).
Edit Because I'm getting the same questions many times:
-It's not as cold as you'd think, currently around 30f with some light snow falling. Winters are in the 0F range and summers are in the 50s. This station is so far north that we're not actually in the Antarctic Circle, and the ocean currents coming down from South America keep things pretty mild. The other US stations get WAY colder, South Pole was -98F a couple days ago.
-I'm a general building maintenance/make-broken-stuff-not-broken/carry-heavy-things-around guy. This place is pretty small so job descriptions are a bit loose.
-I got this job via dumb luck, I had applied years ago to work on the other side (McMurdo), but then my resume happened to be on top of the pile when the guy they had lined up for this job at Palmer decided not to show up for the airplane. They called me in a rush, asked if I could deploy in three weeks, and it went from there. This is my second season down here, I did a winter at this station a few years ago.
-Male/Female ratio is about 70/30, but it can vary drastically depending on how many science groups are here. Dating happens in roughly the same manner as any other population.
EDIT AGAIN OMFG replies. I've done another batch, but I'm going to start skipping the common/repetitive/boring/stupid questions.
FINAL EDIT Seems like this has mostly run it's course, but if anyone still has things they're curious about, feel free to post and I'll answer it in the next day or two. To everyone asking for a link to the job websites, I'm not going to link myself, as there may be some weird legal issues with me being employed currently. I don't know, but I will say that 30 seconds of googling will find you all of the information that you will need. In fact, someone in this thread has actually linked to one of the main pages directly
