Brief Description (Abstract):
Snow accumulation and ablation studies are being carried out in Antarctica since 1982. The accumulation studies being done through monitoring of a stake net work positioned on the ice shelf near the Dakshin Gangotri station site has shown a net accumulation of 62.7 cm during 1999-2001 period. Besides this, polar ice sheet protruding into the Schirmacher Oasis and named as Dakshin Gangotri glacier is being monitored continuously since 1982. This polar ice sheet and land interface is considered sensitive to the ongoing global climate change. This glacier tongue is retreating continuously.
Status: Completed
Purpose: Glaciological observations in Antarctica have attained importance and relevance in understanding the ongoing global climatic changes. The snow accumulation/ablation pattern on the ice shelf and the changes occurring at the land-polar ice sheet interface are considered sensitive to the ongoing climatic changes. The long term program for monitoring the snow accumulation pattern on the Ice shelf near Dakshin Gangotri station is proving to be fruitful in understanding the accumulation pattern. The second program of monitoring the changes occurring at the polar ice sheet land interface is visibly dwindling and is reflecting the ongoing climate change.
