Grand Bahama Bank, Atlantic Ocean

Near Florida and Cuba, the underwater terrain is hilly and the crests of many of these hills compose the islands of the Bahamas. A striking feature of this 2009 Aqua image is the Great Bahama Bank, a massive underwater hill underlying Andros Island in the west, Eleuthera Island in the east, and multiple islands in between. To the north, another bank underlies a set of islands, including Grand Bahama. The varied colors of these banks suggest that their surfaces are somewhat uneven. The banks’ distinct contours, sharply outlined in dark blue, indicate that the ocean floor drops dramatically around them. Over the banks, the water depth is often less than 10 meters, but the surrounding basin plunges to depths as low as 4,000 meters.
