Arctic geodynamics: Continental shelf and deep ocean geophysics. ERS-1 satellite altimetry: A first look
An overall review of the Arctic Geodynamics project is presented. A composite gravity field model of the region based upon altimetry data from ERS-1, Geosat, and Seasat is made. ERS-1 altimetry covers unique Arctic and Antarctic latitudes above 72 deg. Both areas contain large continental shelf area...
