Smoke emitted from forest fires UCAR: Ocean on the move: Thermohaline circulation, University of California Museum of Paleontology. One big part of the oceans role is to soak up energy (heat) and distribute it more evenly around the Earth. Wind produces both waves and currents. Xie and his colleagues also realized that, in shallower layers, currents would naturally have to speed up: In effect, the winds were pushing the same amount of water through a narrower pipe. NASA/Goddard Space Flight Center Scientific Visualization Studio, Earth, Environmental, Ecological, and Space Sciences. surface oceanic circulation results most directly in the. is the transfer of heat through direct contact between the surface and the atmosphere. Since 86% of global evaporation and 78% of global precipitation occur over the ocean, ocean surface salinity is the key variable for understanding how fresh water input and output affects ocean dynamics.
