Sandwell satellite gravity data.

Get ascii xyz topography at 1 minute. Send me an e mail dsandwell ucsd edu. Marine gravity from satellite altimetr. Each dataset contains documentation including source contributor.

White paper in support of a high resolution ocean altimeter mission. If you would like to contribute data to the next version of the global topography grid we would be pleased to use it. Stacked global satellite gravity profiles. Note that odd values of topography e g 2001m are constrained by actual soundings while even values e g 2000m are predicted from gravity.

Topography is v19 1 and gravity is v28 1. The view is towards the west. The gravity field of the indian ocean west of australia based on the new satellite derived gravity model. Yale mm sandwell dt.

Ftp digital gridded topography data at 1 minute. Sandwell global seafloor topography from satellite altimetry and ship depth soundings science v. The research is discussed in a related paper in science. The maps below have been sectioned into 16 clickable regions.

Data parameters include latitude longitude observed gravity and elevation bouguer gravity anomaly land and free air anomaly ocean. Any format is welcome even raw multibeam formats. We also incorporated data from the following missions. Ftp plots for 36 hp plotter.

All marine bathymetry data are welcome. Ftp the raw gravity data 1 minute grid 540mbytes exploring the ocean basins with satellite altimeter data. In 2008 we generated a version of satellite gravity we termed the trident solution by stacking three independently derived solutions of free air gravity from the geosat and ers 1 satellites. Our 2004 solution the dnsc08 solution from the danish national space centre 2008 and sandwell smith v16 1 2004.

Envisat esa ers 1 2 esa and geosat us navy. This satellite altimeter data base contains precise geoid and gravity anomaly profiles which were constructed from the average of 66 repeat cycles of geosat. The satellite altimetry data from cryosat 2 is being provided by esa while data from the jason 1 mission was provided by the national aeronautics and space administration nasa and the centre national d études spatiales cnes. Satellite data reveal formerly unknown tectonics structures.
