Global Bathymetry Model


DTU10 Bathymetry derived from satellite has been mapped with a resolution of 1 minute by 1 minute corresponding to 2 minute by 2 minute resolution at Equator.

Bathymetric information is traditionally obtained from echo soundings during ship surveys. Naturally, most information exists along common ship routes. In poorly surveyed regions with little or any ship traffic, the bathymetry is not well known.Satellite altimetry can provide valuable information about the bathymetry from the measured changes in gravity. With its very dense geographical distribution, the altimeter data from the ERS-1 and GEOSAT Geodetic Missions has a high potential for recovering even small seamounts.
