Sandwell, D. T., and K. A. Poehls, A Compensation Mechanism for the Central Pacific, J., 85, , Sandwell, D. T., and G. Schubert, Geoid. Abstract. GEOS-3/SEASAT radar altimeter images were used to detect major uncharted seamounts in the southwest Pacific. Verification of the predicted seamounts was undertaken during research cruises of HMNZS Tui and R/V Moana Wave during – Four large seamounts were located and mapped by a variety of shipboard recording systems including kHz and kHz echo sounders, seismic Cited by: 1. Using the spherical harmonic representations of the earth's disturbing potential and its functionals, we derive the inverse Vening Meinesz formula, which converts deflection of the vertical to Author: Cheinway Hwang.

A nonlinear filter with outlier rejection is applied to along-track data. We used altimeter data from Seasat, Geosat, ERS-1, ERS-2 and TOPEX/POSEDION missions. Retracked ERS-1 waveforms are shown to improve the accuracy of estimated gravity by: Sep 17,  · The contribution of each altimeter to gravity field recovery is determined using two approaches. In the first approach we compare north and east grids of vertical deflection derived in a variety of data exclusion scenarios. We presume that the most accurate vertical deflection grids are produced when all the GM altimeter data are David T. Sandwell, Hugh Harper, Brook Tozer, Walter H.F. Smith.

SeaBeam uses a 7 msec long transmit pulse. At a water depth of 5 km, the beam width gives along-track and cross-track bathymetry resolution from m beneath the ship to m in the outer beams. The SeaBeam bathymetry has 1 m vertical resolution. This will involve incorporating the latest orbits and tide corrections into the raw satellite altimeter measurements as well as averaging profiles along repeat tracklines to improve accuracy and resolution. Cross-track geoid gradients from global vertical deflection grids will be used to correct the repeat profiles to a common trackline. Correlation of these surveys are able to recover synthetic displacements in the across-track (range) direction accurate to within 1m and in the along-track (azimuth) direction accurate to within m. We attribute these accuracies to the inherent resolution of sidescan data being better in the range dimension than the azimuth dimension.
