Re: Non-scientific jobs in Antarctica
Yes there are jobs for cooks, all but the very smallest bases (of just a handful of people) have a cook. Your problem is your nationality however, many countries only consider their own nationals. Of those who will interview and take others, they will want you to go for interview in their own country which may be problematic.
Given the potential personality conflicts on an Antarctic base, you will almost never get a job (i.e. never so far, but maybe one day in the future?!) by applying remotely. Face to face interviews are a requirement.
