GRAVSAT: Regional Gravity Anomaly Surveys from Satellite Altimetry
Entry ID: SATOBSYS_GRAVSAT

[ Update this Record ]

Summary
Abstract: GRAVSAT provides gravity survey information for the offshore
oil and gas exploration industry. Based on the analysis of
radar altimetry from the ERS-1 Geodetic Phase, completed
in March 1995, high resolution gravity information is derived
from the along track sea surface slopes measured by the
satellite. At the equator, tracks are approximately 8km apart,
reducing to 4km at 60 degrees of latitude, thus providing
similar sampling to many conventional ship surveys. GRAVSAT
gravity anomaly data have been validated against ship
measurements over several areas of the United Kingdom
Continental Shelf, for which the British Geological Survey
have comprehensive datasets.
