Re: Poor sods?
Depends on your nationality. If you're from the UK, then you should be checking the British Antarctic Survey jobs page regularly.
Otherwise, the US bases are managed by
Raytheon (yep, that Raytheon, the ones who make missiles and stuff) (not any more), Leidos (a different US defence contractor). They have their own jobs pages.
If you're not from the US or UK, your home country might have their own Antarctic bases, or you might be able to get a job with the yanks.
Bare in mind though, there's many more people who want a job on the ice than there are open positions, so don't get your hopes up.
