... Currents play a huge role in marine productivity, through a process called upwelling. Sea life is concentrated in the sunlit waters near the surface, but most organic matter is far below, in deep waters and on the sea floor. When currents upwell, or flow up to the surface from beneath, they sweep vi ...

Deep Ocean Basins
... The oceans cover 71 per cent of the surface of the world, and have a volume of 1,370 million cubic kilometers. The average depth is 3,795 meters, four and one-half times the average height of dry land above sea level; 83 per cent of the sea bottom lies between 3,000 and 6,000 meters in depth. Only 1 ...

Another interesting property of the water that is affected by the dissolved salt is the temperature of maximum density. For fresh water this occurs at about 4˚C (40 ˚F) -- i.e., several degrees above ...

Physical oceanography
Physical oceanography is the study of physical conditions and physical processes within the ocean, especially the motions and physical properties of ocean waters.Physical oceanography is one of several sub-domains into which oceanography is divided. Others include biological, chemical and geological oceanographies.
