The light blue shallow water platforms of the Bahamas, (24.0N, 77.0W) which are separated by very deep dark blue channels make for a striking scene. In the foreground is Andros Island and in the background are the Tongue of the Ocean, the Exuma Islands, Exuma Sound and the Atlantic Ocean. The Bahamas are one of the few regions where calcium carbonate precipitates directly out of the water, as the mineral aragonite, to form islands.
