Weekly evolution of ocean surface currents from January 1993 to December 2011. Strong currents such as the Gulf Stream in the Atlantic Ocean, the Kuroshio in the Pacific Ocean and the Agulhas Current along the east coast of Africa are visible. The Antarctic Circumpolar Current and Equatorial currents are also evident, with speeds reaching up to 1.5 m/s. Gravity data from the GOCE mission together with 20 years of satellite altimetry measurements and information from drifters were combined to create this animation of our moving oceans.
