Marine gravity anomaly from Geosat and ERS 1 satellite altimetry
Closely spaced satellite altimeter profiles collected during the Geosat Geodetic Mission (-6 km) and the ERS 1 Geodetic Phase (8 km) are easily converted to grids of vertical gravity gradient and gravity anomaly. The long-wavelength radial orbit error is suppressed below the noise level of the altimeter by taking the along-track derivative of each profile. Ascending and descending slope profile...
متن کاملComparison of Marine Gravity from Shipboard and High-density Satellite Altimetry along the Mid-atlantic Ridge, 30.5ø-35.5øs
We compare new marine gravity fields derived from satellite altimetry with shipboard measurements over a region of more than 120,000 square kilometers in the central South Atlantic. Newly declassified satellite data were employed to construct free-air anomaly maps on 0.05 degree grids [Sandwell and Smith, 1992; Marks et al., 1993]. An extensive gravity and bathymetry dataset from four cruises a...
متن کاملGravity acceleration at the sea surface derived from satellite altimetry data using harmonic splines
Gravity acceleration data have grand pursuit for marine applications. Due to environmental effects, marine gravity observations always hold a high noise level. In this paper, we propose an approach to produce marine gravity data using satellite altimetry, high-resolution geopotential models and harmonic splines. On the one hand, harmonic spline functions have great capability for local gravity ...
متن کاملa suggestion on determining field gravity in sea through satellite altimetry observations, case study; field gravity in oman sea
measuring field gravity in sea due to the accelerations introduced via waves and movements to the gravity measuring systems has a low accuracy since according to einstein's equalent principle, gravimeter isn't able to separate the gravity acceleration from another acceleration. ship borne gravimetery observations by means of like oscillations and accelerations of the ship motion, and ...
متن کاملObserving ocean heat content using satellite gravity and altimetry
[1] A method for combining satellite altimetry observations with satellite measurements of the Earth’s time-varying gravity to give improved estimates of the ocean’s heat storage is presented. Over the ocean the time-variable component of the geoid can be related to the time-varying bottom pressure. The methodology of estimating the ocean’s time-varying heat storage using altimetric observation...
