Improving bathymetry

Gravity field over the Pacific Ocean’s Emperor Seamounts based on CryoSat, ERS and Geosat satellite altimeter measurements of ocean-surface height. At this scale, the gravity field of the ocean reflects seafloor topography, called bathymetry. The improved radar measurements from CryoSat will be used to improve bathymetry. The measurements will be used in the next generation of the seafloor maps in Google Earth.
