On satellite geoidal mapping over the Elan Bank, Antarctica

Satellite geoidal data over the Elan Bank region in Antarctica could be demarcated with the surroundings and confirmed as continental lithosphere. It has been obser­ved that the satellite geoidal map can well demarcate the continental margin region near the Indian coastal region using high-resolution geoid/gravity data. This also helps determine the nature of the lithospheric plate over the Elan Bank. A large portion of land got detached from the Indian plate during the transition processes between the continental and oceanic crust that were originally created by rifting. Satellite geoidal mapping is a comparatively new technique for crust delineation, offshore exploration and tectonics-related studies.
