Journal ArticleDOI
Global Sea Floor Topography from Satellite Altimetry and Ship Depth Soundings
TL;DR: In this paper, a digital bathymetric map of the oceans with a horizontal resolution of 1 to 12 kilometers was derived by combining available depth soundings with high-resolution marine gravity information from the Geosat and ERS-1 spacecraft.
Journal ArticleDOI
Marine gravity anomaly from Geosat and ERS 1 satellite altimetry
TL;DR: In this article, a combination of high-density data from the dense mapping phases of Geosat and ERS 1 along with lower-density but higher-accuracy profiles from their repeat orbit phases is used to construct gravity anomalies from the two vertical deflection grids.
Journal ArticleDOI
Global Bathymetry and Elevation Data at 30 Arc Seconds Resolution: SRTM30_PLUS
J. J. Becker,David T. Sandwell,Walter H. F. Smith,J. Braud,B. Binder,J. Depner,D. Fabre,J. Factor,S. Ingalls,S-H. Kim,R. Ladner,Karen M. Marks,S. Nelson,A. Pharaoh,R. Trimmer,J. Von Rosenberg,G. Wallace,Pauline Weatherall +17 more
TL;DR: A 30-arc second resolution global topography/bathymetry grid (SRTM30_PLUS) has been developed from a wide variety of data sources as discussed by the authors, which is based on a new satellite-gravity model where the gravity-to-topography ratio is calibrated using 298 million edited soundings.
Journal ArticleDOI
New global marine gravity model from CryoSat-2 and Jason-1 reveals buried tectonic structure
David T. Sandwell,R. Dietmar Müller,Walter H. F. Smith,Emmanuel Soliman M Garcia,Richard Francis +4 more
TL;DR: An extinct spreading ridge in the Gulf of Mexico, a major propagating rift in the South Atlantic Ocean, abyssal hill fabric on slow-spreading ridges, and thousands of previously uncharted seamounts are found.
Journal ArticleDOI
Biharmonic spline interpolation of geos-3 and seasat altimeter data
TL;DR: In this paper, the amplitudes of the Green functions are found by solving a linear system of equations and the interpolating curve is a linear combination of Green functions centered at each data point.
