Marine gravity data in the Weddell Sea (Antarctica), 1987/1989/1992/1995 (projects ANT-VI/3, ANT-VIII/5, ANT-X/2, ANT-XII/2)
Listed in NASA Earthdata CMR
The aim of the marine gravity surveys in the Weddel Sea are: a) to develop a model on the break-up of this part of Gondwana, b) to map the ocean-continent boundary c) to develop an idea about the evolution of the area since the break-up of Gondwana.
Description
Sample rate was 10 s, corresponding to 25 m to 150 m depending on ship's speed. Since the data have been collected over a long period of time, they are in various stages of processing.
The following instrument was used: KSS 31/25 sea gravity meter. The geographical coverage is as follows: For ANT-VI/3, ANT-VIII/5, ANT-X/2: about 20000 km of gravity data have been collected in the Weddell Sea, Antarctica. These data cover the entire region from shelf to deep sea.
