I realize this thread a bit on the old side, but not so much relative to some of the others. I was unable to find out from the NSF website who had taken over as the support contractor. This thread led me in the right direction.
However, I'm not able to find any job postings on the link Paul posted above. Here's a site I found through a subsequent Google search, listing the positions available:
ANTARCTIC SUPPORT CONTRACT
While I don't personally qualify for any of those listed, Lockheed-Martin also lists several "partners" in the contract, one or two of which aren't to be found on the NSF's page for support opportunities, here
I hope this list is comprehensive and that I've helped a bit. Now perhaps you can help me. What sorts of jobs does someone with relatively little work experience qualify for? Assume, for the sake of simplicity (and being conservative), that I am fresh out of high school with only some volunteer experience under my belt (this is not the case). Would this inexperience disqualify me for pretty much all jobs on the ice? What if my work experience is a bit longer; three years of college and two years job experience? I don't really care if it's menial.
It seems that this "Balkanization" of support contractors to different firms holding the contract for different things is going to make the application and job search process significantly more difficult.
