Eleuthera Island, Bahamas seen from STS-66. The striking views provided by the Bahama Islands lend insights into the important problems of limestone (CaCO3) production and transport. This photograph includes the southern part of Eleuthera Island in the northern Bahamas. The hook-shaped island encloses a relatively shallow platform (light blue) which is surrounded by deep water (dark blue). The feathery pattern along the western edge of Eleuthera's platform are sand bars and sand channels created by tidal currents sweeping on and off the platform. The channels serve to funnel large amounts of CaCO3 off the platform and into the deeper water.
