Last Remaining Palaeocrystic Ice (IMAGE) University of Massachusetts Amherst Caption One of the last remains of the formerly extensive ice off the coast of Ellesmere Island, Arctic Canada, pictured in July 2002. At the end of the last Ice Age, ice such as this would have covered large parts of the Arctic Ocean and been up to 164 feet (50 meters) thick in places, creating an enormous reservoir of fresh water independent from land-based lakes and ice sheets, say Raymond Bradley of UMass Amherst and Alan Condron of Woods Hole Oceanographic Institute in a new paper on past climate.
