| Abstract: | A high resolution satellite gravity and bathymetry data along two N-S trending profiles have been interpreted using gravity forward modeling technique off Prydz Bay, East Antarctica. The crustal density model indicates the oceanic crust has a distinctive character with a smooth upper surface and the Moho depth varies from ~20 km shoreward to <12 km offshore. The Moho shallows from~19 km to 15 km in between 60 and 80 km along the pfofile A-A’. It occurs around
13 km further offshore. The present study infers the presence of ~8 km thick sediments on the southern side while in the north the thickness is about 2 km. The shelf break occurs between 120-130 km from the beginning of the profile A-A’ and between 40 and 70 km along the profile B-B’. |
