Global surface currents 2005-2007. Computer visualisation showing ocean surface currents around North and Central America, centred on the Caribbean Sea and Atlantic Ocean, during the period from June 2005 to December 2007. The main current system operating in this area is known as the Gulf Stream (dense, white, upper centre). This visualisation was produced using model output from the joint MIT/JPL project: 'Estimating the Circulation and Climate of the Ocean, Phase II' (ECCO2). ECCO2 uses the MIT (Massachusetts Institute of Technology) general circulation model (MITgcm) to synthesise satellite and in-situ data of the global ocean and sea-ice at resolutions that begin to resolve ocean eddies and other narrow current systems, which transport heat and
