However, shelf ice is fluctuating in nature, due to direct contact with the sea. Changes in the extent of shelf ice with varying climatic conditions can be interpreted using various remote sensing satellites; but these satellites do not yet have the capability to retrieve depth information. Radio-echo sounding provides an efficient tool to measure ice depth. The survey results show that the shelf ice thickness varies between 20 and 60 m. 3-D map of the surveyed area was prepared using the latitude and longitude information from the GPS and the depth information from the GPR. After combining various GPR profiles, it is observed that the shelf ice thickness decreases while moving towards the sea in the north direction and it increases away from the sea edge towards the south. Sharp reflections of radio waves from two different levels (depth) were observed at few locations in radargram, although these reflections are from very limited area but their interpretation is a further area of research.
