WebUsing climatological atlas data and historical hydrographic data, the relationship between dynamic height anomaly ΔD and acoustic round-trip travel time τ in the Pacific Ocean is investigated. A tight, linear relation is found in a region centered on the Kuroshio and Kuroshio Extension. In this region, the slopem of the relation is approximately −50 dyn m …

WebAbstract Dynamic height is calculated from XBT and surface salinity data in the central Pacific using a mean temperature–salinity (T–S) relation in the usual way below the thermocline but assuming isohaline water in the upper layer where the temperatures are isothermal. This scheme produces a better estimate of dynamic height than the use of a … 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 ...
