Watch this NASA film showing surface currents circulating in a high-resolution, 3D model ofthe Earth's oceans. Driven by wind and other forces, currents on the ocean surface cover our planet. Some span hundreds to thousands of miles across vast ocean basins in well-defined flows. Others are confined to particular regions and form slow-moving, circular pools. Seen from space, the circulating waters offer a study in both chaos and order. Mesmerizing.
