The sverdrup (symbol: Sv) is a non-SI unit of volume transport. It is used almost exclusively in oceanography to measure the volumetric rate of transport of ocean currents. It is named after Harald Sverdrup. It is equivalent to 1 million cubic metres per second (264,000,000 USgal/s).The entire global input of fresh water from rivers to the ocean is equal to about 1.2 sverdrup.
