Subglacial precipitate

Caption

A subglacial precipitate from from the Pensacola basin that formed 200,000 years ago. Combined with data from other samples, the age and uranium isotopic composition of this sample suggests that parts of the East Antarctic ice sheet were deglaciated during a warm interglacial period about 400,000 years ago.
