Underwater mountains help ocean water rise from abyss At high latitudes, such as near Antarctica and the Arctic Circle, the ocean's surface waters are cooled by frigid temperatures and become so dense that they sink a few thousand meters into the ocean's abyss. Scientists have now identified a mechanism by which waters may rise from the ocean's depths to its uppermost layers. https://www.sciencedaily.com/releases/2017/03/170306092725.htm
