The Department of Ocean Development, Government of India took initiative towards the development and use of marine non-living resources for the socio-economic benefit of the society. Indian Oceanographic Vessel Gaveshni collected the first sample of polymetallic nodules from the Indian Ocean in 1981. A multidisciplinary team of experts participated in this endeavour. Indian efforts continued and as a recognisition of extensive work carried out by India, a site of 150,000 sq. km. was allotted in Central Indian Ocean Basin by PREPCOM. India was registered as first Pioneer Investor in August, 1987 along with Japan, France and the Soviet Union (now Russia). As on today, there are seven Pioneer Investors. India is the only country with the mine site allocated in Central Indian Ocean Basin while all others are in Pacific Ocean. Indian efforts are concentrated towards Survey & Exploration, technology development for mining and metallurgy and environmental impact analysis as a part of the developmental activities. An overview of the progress and the future plan in these areas is briefly presented. The Polymetallic Nodule programme is one of the major R&D efforts in India towards the development and use of Ocean Science & Technology for the exploration of the marine non-living resources for the socio-economic benefit of the society. This multi-disciplinary programme is being executed by multiinstitutional participation. on 26th January, 1981 the Indian Oceanographic Vessel "Gaveshni" collected the first sample of polymetallic nodule from Indian Ocean. Today India is the only country with the mine site allocated in Central Indian Ocean Basin while all others are in Pacific Ocean. In this programme, survey & exploration, mining technology, extractive metallurgy and environmental impact analysis are the four areas where the Indian efforts are directed. An overview of the progress and the future plan in these areas is briefly presented.
