It sounds like you either are or were formerly posted in the Antarctic — any advice about how to get involved, and maybe get a shift working there, as a civilian with a technical background but without much in the way of a research background? Or is it just totally off the table?
Used to be pretty easy to sign up as a dishwasher or that kind of thing. If you are in interested in science, find a PI looking for grad students. Edit: I read more closely. There are technical grantee groups as well, like UNAVCO and IRIS PASSCAL. Not too hard to get a job with one of those.
Lots of ways in... Everybody I know who has really tried has made it down there.
