Shrimp-Like Creature Discovered at Windless Bight, Antarctica - 600 Feet Beneath Ice Sheet
At a depth of 600 feet beneath the West Antarctic ice sheet, a small shrimp-like creature managed to brighten up an otherwise gray polar day in late November 2009. This critter is a three-inch long Lyssianasid amphipod found beneath the Ross Ice Shelf, about 12.5 miles away from open water in the region called Windless Bight. NASA scientists were using a borehole camera to look back up towards the ice surface when they spotted this pinkish-orange creature swimming beneath the ice.

and 14.3 miles south of Mount Erebus.
