Princess of whales: How a naked female scientist tries to tame belugas in the freezing Arctic, article.
This Russian scientist has some kind of balls: these are arctic waters, and she swims underwater with the whales up to ten minutes! OMG.
Update: A said:
the photographer has a very nice flickr page with many more underwater images.
btw, the story about the whales not liking swim suits is nonsense (see the flickr stream ..)
Short video in Russian.
