f Levelling Marine Potential Field and Bathymetry Data - a New Approach

The levelling of marine potential field and bathmetry data has been a difficult and often time consuming problem. As part of the Australian Geological Survey Organisation's (AGSO) Timor Sea Project, a major upgrade of the marine ship-track potential field and bathymetry data which have been acquired on the north-west Australian margin since 1963 has been undertaken. AGSO and Desmond Fitzgerald and Associates have developed new techniques for correcting crossover and other errors in these data, thereby enabling the production of high quality images for interpretation.
