Gulf Stream in the Atlantic
East Coast, United States
April 2003
A river of warm ocean water, the Gulf Stream has been made visible moving northward in the Atlantic Ocean. Color variations represent concentrations of chlorophyll found in microscopic marine plants called phytoplankton. These organisms thrive in cooler waters, so chlorophyll concentrations fall abruptly at the edge of the Gulf Stream. The bright red and yellow zones show areas of cooler water at the northern edge of the Gulf Stream.
