Islands of the Bahamas and the Bahama Banks24.7N 78W
This image shows several islands in the Bahamas. Situated in the upper part of the image are Grand Bahama (left) and Great Abaco (right). In the lower part are Andros Island (left), New Providence (center) and Eleuthera Island (right).
The water around the islands appears lighter in color, then suddenly changes to dark blue, because the islands of the Bahamas sit atop submerged carbonate platforms with sudden drop-offs at their edges. These platforms are known as the Bahama Banks. The water above the platforms is shallower and thus appears lighter blue than the significantly deeper waters beyond the drop-offs.
