These waters make up about 10% of all the water in the ocean. These waters are the upper 400 meters of the ocean. 2. Deep Water Currents -- Thermohaline Circulation. These waters make up the other 90% of the ocean. These waters move around the ocean basins by density driven forces and gravity. WebFurthermore, wind-driven surface currents only affect the top 100-200m of water, meaning surface currents only involve about 10% of the world’s ocean water.
