Re: Diving Jobs?
There aren't any commercial diving jobs at the moment in the way I assume that you mean.
There are diving operations however and these are run by professional divers on contracts, usually running and supporting biological research programmes. The jobs are advertised by the National Antarctic Programmes on their websites and also in dive magazines.
In the first place you might try contacting the National programmes as they might be able to alert you more readily to job vacancies.
