Moho depth or simply, Moho, in general, describes the boundary between the earth’s crust and the mantle and is a very important geophysical parameter. It is also related to the earth’s crustal thickness at any point. Geoid and gravity anomalies derived from satellite altimetry are gradually gaining importance in marine geo-scientific investigations. However, satellite gravity technique is not working over land/continent. So, we need to develop technique like the VMM model which is equally working over land. In addition of generating crustal thickness, it also saves energy to generate Bouguer anomaly over land and ocean.

Abstract


Moho depth or simply, Moho, in general, describes the boundary between the earth’s crust and the mantle and is a very important geophysical parameter. It is also related to the earth’s crustal thickness at any point. Geoid and gravity anomalies derived from satellite altimetry are gradually gaining importance in marine geo-scientific investigations. However, satellite gravity technique is not working over land/continent. So, we need to develop technique like the VMM model which is equally working over land. In addition of generating crustal thickness, it also saves energy to generate Bouguer anomaly over land and ocean.
