Coastal Community Programmes

Island Development

The emphasis of this programme is on building up of infrastructure and expertise in Ocean Science and Technology for Islands through development and transfer of technology in the area of marine living resources, which will bring in socio-economic benefits to the island community. Several experiments have been carried out under the programme being implemented by National Institute of Ocean Technology in the following areas:

  1. Fattening of spiny lobsters and mud crabs
  2. Biochemical analysis of lobsters and live feeds
  3. Water quality and disease management
  4. Spawning and larval rearing
  5. Survey of lobster resources in Gulf of Mannar and Andaman Islands.

Various infrastructure facilities were also developed at the Andaman and Nicobar Centre for Ocean Science and Technology, National Institute of Ocean Technology, Port Blair.

Marine Archaeological Findings in the Gulf of Cambay

Detailed underwater surveys carried out in the Gulf of Cambay, about 20 km west of Hazira, brought to light, the presence of a submerged palaeochannel traceable to a length of 9 km. Associated with this on either side are basement like features found in a grid pattern at water depths of 20-40 m. Sub-surface sampling revealed stone artifacts, potsherds, hearth pieces, animal bones and human teeth embedded in fluvial sands and silts. A carbonised wooden log was found and dated to around 9500 years BP by 14C method at laboratories in India and abroad. Marine magnetic survey carried out does not indicate the presence of any major metallic debris/objects. This appears to be one of the early records of prehistoric human activity of early Holocene age in the marine environment of India.

Under a national programme involving over a dozen laboratories and institutions, detailed surveys sampling, mapping and analysing is in progress. T.L. dating of pottery is consistent with 14C results. Submergence of structures in Cambay appears to be a combination of sea-level rise and tectonic disturbance. The existence of Cambay in the north-west and Poompuhar in the south-east – both existing some 7500 BC, open many vistas of prehistory.
