A fitting addition to his interactive global windmap, Cameron Beccario‘s interactive map of Earth’s ocean currents takes near-realtime data-mapping to the seas – and the results are mesmerizing.

The first thing to keep in mind is that ocean currents are very thin compared to the diameter of Earth. They’re only about four kilometers (13,000 feet) deep at most, and surface currents can be just ...

The radio waves sent out by the 78 transmitters in the network are reflected back by the ocean's waves, giving scientists a 24-hour-a-day map of coastal currents.

Scientists say data from satellites have allowed them to create one of the most detailed maps of the globe's ocean currents, along with their movements, ever produced.
