Dynamic height oceanography
WebThe calculated dynamic heights are plotted and contoured. Current directions are obtained by application of the geostrophic principle; current velocities are computed from the slopes of the surface topography. A table of specific volume anomalies, necessary for the height computation, has been developed. WebThe sea surface height relative to the geoid (the mean ocean surface of the Earth if the ocean is at rest) is derived from TOPEX/Poseidon, Envisat, Jason-1, and OSTM/Jason-2 altimetry measurements. Altimetry is a technique for measuring height. Satellite altimetry measures the time taken by a radar pulse to travel from the satellite antenna to ...
