An Assessment of Geo-Scientific Investigation in the Antarctic Region

During the initial period of about 25 years (1981-2006), systematic geological mapping covering an area of about 19,000 sq. km, continuous monitoring of Dakshin Gangotri (DG) snout, ice core drilling, and limnological investigations are some of the significant achievements of GSI in the field of Antarctic geoscience. For the first time, ground penetrating radar (GPR) survey for lake bathymetry has been introduced in Schirmacher Oasis. Collaborative work has resulted in quantifying the annual vector movement of the ice sheet in the Schirmacher region.
