Ocean floor mapping

Why Aerial mapping UPSC in news

Recently INCOIS go for Aerial mapping of ocean floor. It will conduct bathymetric study with national remote sensing centre of Andaman and Lakshadweep islands.

Bathymetric study

Indian National Centre for Ocean Information Services (INCOIS) is planning to take the help of the National Remote Sensing Centre(NRSC) for aerial mapping of the Andaman and Nicobar Islands and Lakshadweep to get a better picture of ocean floor, also called ‘bathymetric’ study.

Bathymetric study

Work of national remote sensing centre

National remote sensing centre has already done asimilar high resolution topographic Airborne Laser Terrain Mapping (ALTM) for the entire coastal areas of the country and we are in the process of integrating the data for a 3D multi hazard mapping of both the east and west coastline for a more precise picture of the ocean floor.

Use of aerial mapping

This study has become imperative in view of the recent tsunamis of the Indonesian coasts. where more than the quake related highwaves, damage was due to landslides under the seabeds causing sudden wave surges. It also leading too much damage without giving sufficient time to alert people. The research institute, under the Ministry of Earth Sciences, had also identified ‘gaps’ across the coast of Andhra Pradesh and Odisha for installing more tide gauges for better monitoring of the sea and more accurate prediction of impending disasters like cyclones. These will be in addition to the 36 already in the Bay of Bengal. INCOIS scientists with their counterparts in the Chennai based National Institute of Ocean Technology and an United States independent scientific agency,Massachusetts based Woods Hole Oceanographic Institution, have been mining the data recorded by a unique ‘Flux Buoy’ retrieved from the Bay of Bengal off the Kolkota coast recently.
