Scientific paper

The gravity field in the Norwegian-Greenland Sea is analyzed and mapped using new 35-day ERS-1 altimeter data. Spectral analysis indicates that the time varying parts of the sea surface heights dominate the signal at a level of about 7 cm at frequencies higher than 3 cy/deg. At lower frequencies, there is a prominent stationary signal in the northern region. The recovered gravity field correlates exclusively with major geological structures.
