    Abstract
    High-resolution seismic reflection profiling has revealed the occurrence of acoustic masking, pockmarks, gas seepages and plumes on the inner shelf, middle shelf and upper continental slope of western India, between 20 and 50 m, 60 and 75m, and 170 and 260 m water depths, respectively. A typical 40-km long seismic section trending in a NW-SE direction - from the upper slope is characterized by anticline-syncline structure and culminates toward the NW. In some place fluid or gas escape features and plumes appear 2-12 m above the seafloor. Active and relict-type pockmarks are noticed. Out of thirty well-recognized pockmarks along the section, six are buried. In general, the pockmarks, are 80-130 m in diameter and 0.75-2.5 m deep. Biogenic gas due to organic-rich sediments in the slope or thermogenic gas emanating from deep-seated faults, fractures and lineaments in the region may have given rise to these features.
