Pack Ice in Baffin Bay Between Baffin Island and Greenland
The ice melts from above and below so forming an indentation at the water line and the occasional small melt pool on top which ends up reaching through to the sea below. The good thing about pack ice is that it kills any swell and so calms the sea.
