This image of black water off the coast of Florida was acquired on January 9, 2002, by the Sea-viewing Wide Field-of-view Sensor (SeaWiFS). Scientists and local fishermen are not sure what is coloring this typically turquoise water black. Amid growing concern, scientists are now trying to determine the source of the black water.
