A still image showing the Gulf Stream around North America taken from Perpetual Ocean, a visualization of some of the world's surface ocean currents from June 2005 through December 2007, supplied in this handout photo by NASA March 27, 2012. The visualization was produced using NASA/JPL's computational model called Estimating the Circulation and Climate of the Ocean, Phase II or ECC02, a high resolution model of the global ocean and sea-ice.
