Gravity, Geoid, Isostasy and Moho Depth in the Ross Sea, Antarctica.

In the framework of several international research projects performed in Ross Sea (Antarctica) in the last years marine gravity data, high resolution reflection seismic line sand deep seismic sounding profiles have been acquired. The gravity data set has been used to compute maps of Bouguer anomaly,...

Description
Summary:In the framework of several international research projects performed in Ross Sea (Antarctica) in the last years marine gravity data, high resolution reflection seismic line sand deep seismic sounding profiles have been acquired. The gravity data set has been used to compute maps of Bouguer anomaly, isostatic anomaly, isostatic correction and local geoid undulations. Forward modelling of seismic and gravity data has been also used to compute the depths of the Crust-Mantle discontinuity.
