A Factor of 2-4 Improvement in Marine Gravity and Predicted Bathymetry from CryoSat, Jason-1, and Envisat Radar Altimetry: Arctic and Coastal Regions

Abstract

LONG-TERM GOALS: *Improve our understanding of the ocean basins for scientific research and Naval operations. OBJECTIVES: *Improve global marine gravity maps by a factor of 2 in deep ocean areas and a factor of 4 in the Arctic areas and on shallow continental margins. *Use these improved gravity maps along with a global compilation of soundings to refine a 30-arcsecond bathymetry model (SRTM30_PLUS). *Prepare the next generation of scientists for ocean research.
