Brief Description (Abstract):

Snow accumulation/ablation on the ice shelf is being monitored through a network of stakes near Dakshin Gangotri Station, since 1986. This study is aimed at finding the changes at the surface of the shelf ice. During the 15th expedition, it was found that all the old stakes were uprooted, possibly due to blizzards. Because of this, the continuity of the observation was broken and it was necessary to set up a new set of stakes for monitoring of ice shelf. A systematic network of 25 stakes has been installed in Feb 96 and ten sets of observations were taken by the wintering team of GSI, to study pre-winter and post-winter patterns of deposition.

Status: Completed

Purpose: In the 5th expedition, Kaul et al. (1986) had fixed a network of 9 stakes on ice-shelf, about a km away from Dakshin Gangotri station. This network was upgraded during subsequent expeditions, as and when required, and a continuity of observations was maintained on the ice shelf, studying the various patterns of accumulation and ablation. In the summer of the 15th expedition, the GSI team found that each and every one of the old stakes was uprooted. This could be either due to human interference, or due an extraordinarily severe blizzard. Whatever the reason may be, it has broken the continuity of scientific observations on the shelf during the summer of 1996. During February 96, GSI team has fixed up a new set of 25 stakes, each separated by a distance of 50 m. Thus, a representative area of 200 m x200 m has been marked out on the shelf. The pattern of stakes fixation.
