There are a lot of results simply in a Youtube search on "antarctica" + "circumnavigation". [+] There are some new researchers who are making the rounds lately too. I'm not up to speed on all of it so I'll just inlude this playlist by jeranism who is known in the community now. Some of the videos may not have much to do with circumnavigating Antarctica directly. I haven't watched them all. I post the playlist here as raw data to be watched and chosen from for my future work on the actual circumnavigation that I like to focus on.
