This satellite image of the Sargasso Sea shows warmer water in red and orange, cooler water in blue and purple, and land and clouds in black. The legend on the left shows sea surface temperatures in degrees Celsius. The Gulf Stream is visible as a "river" of warm (red) water flowing along the east coast of the United States and then bending seaward at Cape Hatteras in North Carolina. Three cold core rings can be seen between the Gulf Stream and Cape Cod.
