Determination of Gravity Anomalies over the Arabian Sea

Ahmed Abdo Ali, Liu Jing Nan and Jiang Wei Peng

Abstract:
Gravity anomalies derived from satellite altimetry are progressively taking the place of ship-borne gravity for many marine geo-scientific investigations this paper compares the marine gravity anomalies-derived from multi-mission satellite altimetry-with gravity anomalies implied by the EGM96 global geopotential model. The results show some significant differences among these gravity data sources. Ocean satellite altimetry implied free-air gravity anomalies have had the shortest wavelength removed during the processing to generate the optimal solution between multiple radar altimeter missions. Compute gravity anomalies by LSC using along-track,differeced geoidal heights and height slopes. Gravity Anomalies over the Arabian Sea (latitudes: 0-25 °N and longitudes: 35-70 °E) is computed by using along track deflections of vertical and grid along track deflections of vertical using Shepard`s method of gridding procedure and finally the gravity anomalies were computed using the inverse Vening-Meinesz formula we used altimeter data from Topex/Poseidon, Jason1, Geosat, ERS1 and ERS2 missions.
