The sverdrup, named in honour of the pioneering oceanographersHarald and Otto Sverdrup, is an unit of measure of volume transport. It is used almost exclusively in oceanography, to measure the transport of ocean currents. It is equivalent to 106m3/s or 0.001 km³/s. Its symbol, when it is granted one, is either Sv or S, which conflicts with the sievert or the siemens, respectively.
Sverdrup was one of Vilhelm Bjerknes's original collaborators in the Bergen School of Meteorology and then focused on oceanography.
Harald Ulrik Sverdrup (November 15, 1888 – August 21, 1957) was a Norwegian oceanographer and meteorologist who made a number of important theoretical discoveries in these fields.
The sverdrup, a unit of volume flux, bears his name.
