Turquoise Waters Over Bahama Banks25.0N 77.3W
The waters around the islands of the Bahamas appear bright turquoise that suddenly changes to dark blue due to the Bahama Banks. The Bahama Banks are submerged carbonate platforms that make up much of the Bahama Archipelago. Since the platforms suddenly drop off to great depths, the water above them is shallow and appears lighter in color before suddenly changing to dark blue.
Also visible in the full image are the island-nation of Cuba (below) and the Florida Peninsula, belonging to the USA (above). Both areas are covered by dotted white popcorn clouds, probably due to an increase in photosynthetic activity in the vegetation in the region.
