Perpetual Ocean -- Ocean Surface Currents Animation

Last year, a group of NASA scientists and animators put together this animation of the world’s ocean surface currents, based on ocean flow data for June 2005 to December 2007. The video starts over the Atlantic, and as the globe rotates, you can see the whorls and waves dancing across the ocean, the relative calm of the Pacific, and the stillness around Antarctica. [...] The tool NASA used to make the visualization — ECCO2 or Estimating the Circulation and Climate of the Ocean

ECCO2 Home Page

To increase understanding and predictive capability for the ocean's role in future climate change scenarios, the NASA Modeling, Analysis, and Prediction (MAP) program is funding a project called Estimating the Circulation and Climate of the Ocean, Phase II (ECCO2): High-Resolution Global-Ocean and Sea-Ice Data Synthesis. ECCO2 aims to produce increasingly accurate syntheses of all available global-scale ocean and sea-ice data at resolutions that start to resolve ocean eddies and other narrow current systems, which transport heat, carbon, and other properties within the ocean.
