Sverdrup

From Free net encyclopedia

The sverdrup, named in honour of the pioneering oceanographer Harald Sverdrup, is a unit of measure of volume transport. It is used almost exclusively in oceanography, to measure the transport of ocean currents. It is equivalent to 106 cubic meters per second or 0.001 km³/s. Its symbol is Sv. Note that the sverdrup is not an SI unit, and that its symbol conflicts with the sievert's.

Recent studies suggest that the water transport in the Gulf Stream steadily increases from 30 Sv in the Florida Current to a maximum of 150 Sv at 55°W longitude. The entire global input of fresh water from rivers to the ocean is equal to about 1 Sv.
