Distribution of strontium in sediments of the Minicoy atoll, Lakshadweep
Sr content in 67 sediment samples collected from the Minicoy reef and lagoon varies from 3960 to 7000 ppm (av. 5630 ppm). The concentration increases from the reef (c 4,000 ppm) in the north and west to the centre of the ...
Superficial mineral resources of the Indian Ocean
The sea floor of the Indian Ocean and the continental margins bordering the ocean are covered by a wide variety of terrigenous, biogenous and anthigenic mineral deposits. The biogenous deposits in the Indian Ocean comprise ...
A note on the occurrence of ortho-amphibolites on the inner shelf off Bhatkal, west coast of India
(Geological Society of India, 1987)
The total magnetic intensity map of the area shows that the inner shelf to a depth of 50m is marked by a zone of magnetic closures. The occurrence of offshore orthoamphibolites and the qualitative interpretation of the ...

In mid 1970's the National Institute of Oceanography, Goa, India prepared a plan for systematic regional, geological and geophysical surveys of the continental margins of India. This involved over 75,000 km of underway ...
Acoustic masking due to gases in shallow seismic profiling on the shelf off Bombay
Shallow seismic profiling on the inner shelf off Bombay indicates 25-35 m thick acoustically transparent clays covering the seabed. At depth of 22 to 30 m and 50 m the profiles and echograms are marked by turbidity resembling ...
