Brief Description (Abstract):

During Indian Antarctic Expeditions, monitoring of iceberg is an important programme of GSI since very beginning. These icebergs originate from the ice shelf, formed during the last glacial maxima. Iceberg monitoring in the Antarctic Waters during onward voyage of XXIV Indian Antarctica Expedition has revealed concentration of icebergs in two well-defined zones separated by an iceberg free zone. Distribution pattern and the analyses of size, shape parameters of these icebergs have shown that the majority of large size (> 500 m) tabular icebergs are concentrated in the area close to the Antarctic shelf line whereas the non-tabular such as pinnacled, domed, wedge shaped and other types disintegrating icebergs (of <500 M class) are mostly concentrated in the area away from the shelf.

Status: Completed

Purpose: The Antarctic water and Southern Ocean encircling Antarctica are marked by the presence of varieties of icebergs with characteristic features. These are formed by calving of ice blocks from ice shelves or glacier tongue floating into Antarctic Waters. In the route of Indian Antarctic Expedition, the icebergs are mainly formed from the ice shelf. The icebergs are carried away from the place of their origin by the prevailing ocean currents of Southern Ocean. Monitoring of icebergs has been a continuous programme of Geological Survey of India (GSI).
