dc.description.abstractBathymetric, side scan sonar and seismic studies were conducted in shallow waters of 11-18 m off Redi along central west coast of India to understand the stratigraphy and structural features. Bathymetric contours suggest the existence of a palaeochannel running across the region in ENE-WSW direction. Shallow seismic surveys indicate a pseudo escapment of more than 7 m deep between 12-14 m water depths. Eastern part (11-14 m) of the escarpment indicate the existence of gas-charged sediments (silty clays) within 3 m of sea floor. In the west (14-18 m), the subsurface layer (silty sand?) observed at 10-12 m from sea floor is breached and pushed upwards into surface layer indicating inverted U-like and cylindrical features. These features reaching within 4-5 m of sea floor suggest the continuation of gas-charged sediments in the west. Isopach and gas-charged sediment maps of the region lead to the demarcation of the areas that should be avoided by any offshore engineering activities.
