Most of the Western Bahama Banks, the Tongue of the Ocean and Andros Island (24.0N, 77.0W) as well as north central Cuba with its fringing reefs can be seen in this one view. The green water over the banks is less than 3 meters deep but the dark blue of the Tongue is 2000 meters deep. All the sediment on the banks, including the material that forms the islands, is calcium carbonate precipitated from sea water by animals and plants.
