Brief Description (Abstract):

During the 2nd Indian Antarctic Expedition, Dakshin Gangotri glacier snout was identified in the Schirmacher Oasis, East Antarctica. Since then, the monitoring of the snout is a regular annual observation. Analysis of the recorded data shows that from 1996 onwards there is a recession of 65 to 70 cm per annum. During 2007 and 2008, there is a yearly average recession of 110 cm. Detailed analysis shows that there is variable amount of recession at different parts of the snout. In the year 2001, additional measurement points were set up along the Western Wall of the glacier. In 2008, accumulation/ ablation studies in India Bay region show an average accumulation of 5.9 cm on the Ice Shelf, but ablation is recorded at few stakes.

Status: Completed

Purpose: The study involves the measurement of DG Glacier Snout and its western flank with respect to fixed observation points. The permanent markers were fixed in 1996, from where the distance of the projected points along a marked direction are measured every year. The accumulation and ablation pattern on the ice shelf area near former Dakshin Gangotri station in India Bay region was obtained using a network of 16 stakes, fixed over the ice shelf in a grid of 4 stakes in each row, separated 50 m ? 50 m, encompassing an area of 22500 square meters.
