Brief Description (Abstract):

Dakshin Gangotri glacier in Schirmacher range is being monitored by the GSI since 1983. It was being monitored on an yearly basis from two survey stations. In the 15th expedition, 19 reference points were marked all along the periphery of the glacier and observations were taken on a monthly basis, for one full year. The cycle of advancing, bulging, calving and retreating of the glacial front were recorded. It is conclusively proved that the polar glaciers are also markedly retreating.

Status: Completed

Purpose: The movement of a polar glacier tongue, named Dakshin Gangotri (70? 4520 S lat. and 10? 35 05 E long.) in Schirmacher range, is being constantly monitored since 1983 (Kaul et al., 1985), to understand the dynamic changes in the continental ice front of Antarctica. This polar tongue (Fig.1) is a remnant of an earlier glacier, which was overriding the Schirmacher range and crossing it at this point towards north. Glacial striations on the rock surfaces display the palaeo- movement directions of the glacier. Two permanent survey stations G and H had been established earlier and the observations of the snout were taken from these points. The snout was monitored every year in the months of polar summer, (Jan or Feb). The resultant comparative profiles were drawn to record the advance/retreat during the year. One such profile, comparing the outlines of 1995 and 1996.
