Geoid and gravity anomalies in the North Sea Area derived from SEASAT-altimeter data

As part of the work of the SEASAT user research group of Europe altimeter data of SEASAT-1, preprocessed by Jet Propulsion Laboratories, have been used to derive a high-precision geoid as well as gravity anomalies für the North Sea Area. The altimeter data have been corrected first for tidal effects; the tidal signal was computed at the Institute of Oceanographic Science, Bidston, using a high precision tidal model for the North Sea.
