Abstract

GEOMORPHOMETIC ANALYSIS OF SUBMARINE SLUMPS USING GIS
Track: Ocean and Maritime
Authors: Andrew Menezes, Bishwajit Chakraborthy, Mahender Kotha

Use of GIS in oceanography and the availability of high resolution bathymetry have given new impetus for seafloor mapping and analysis. This presentation gives our experience in multibeam data acquisition(WCM of India)and GIS tools for processing for DEM creation & derive geo-morphometric parameters to evaluate submarine slumps & slope stability. Traces of fluid flows (pockmark seepages) are identified and slump areas are visualized by analysis of the surface morphology of the continental slope.
