''Combined, the north and south polar ice caps are believed to hold the equivalent of two to three million cubic kilometers (0.47-0.72 million cu. miles) of ice, making it roughly 100 times more than the total volume of North America's Great Lakes, which is 22,684 cu. kms (5,439 miles). The study was done by researchers at France's National Institute of Sciences of the Universe (Insu), using the Italian built SHARAD radar sounder on the US built MRO.'' [source]
