Abstract

The coastal regions of Antarctica, where substantial deposits of oil and (other minerals are reported, consist of a number of ice shelves. Such areas encounter severe weather conditions and flow of the ice shelf which severely affect the life of the structure/installations. The Indian Antarctic station Dakshin Gangotri located in east Antarcticaat 70 degrees S 12 degrees 05' E lies on one of such ice shelves. The paper brings out the criteria which should be kept in niind while selecting the site of a structure on an ice shelf and a case study for selection of site of Indian research station Diikshin Gangotri 'in December 1983 of which the author was the leader of the first wintering party.
