Abstract

Within the European AGMASCO project (Airborne Geoid Mapping System for Coastal Oceanography), cooperations with user groups from Oceanography, Geology and Geodesy have been arisen. The airplane based gravimetry/altimetry system provides a rapid surveying procedure which is specially employed in not easily available marine and land areas (e.g. coastal/shelf areas, polar regions). In Geodesy, it serves for the improvement and refinement of already existing geoids and of future satellite-only gravity field models. The availability of precise regional geoids allow the monitoring of the dynamic sea surface topography by satellite altimetry. For applications in geology and geotechnics, gravimetry is a pre-surveying method for exploration of energy resources.

The AGMASCO products such as gravity anomalies, sea surface heights and regional geoids (Skagerrak/1996, Fram Strait/1997, Azores/1997) will be discussed in this paper. The accuracy corresponds to the state-of-the-art of airborne gravimeuy/altimetry.
