Ross Ice Shelf
The Bay of Whales was a natural ice harbour, or iceport, indenting the front of the Ross Ice Shelf just north of Roosevelt Island, Antarctica. It is the southernmost point of open ocean not only of the Ross Sea, but worldwide. The Ross Sea extends much further south – as far as the Gould Coast, some from the South Pole – but most of that area is covered by the Ross Ice Shelf rather than open sea.
