The National Institute of Ocean Technology (NIOT) was established in November 1993 as an autonomous society under the Ministry of Earth Sciences, Government of India

• Major aim is to develop reliable indigenous technologies to solve the various engineering problems associated with harvesting of non-living and living resources in the Indian Exclusive Economic Zone (EEZ).
• NIOT has developed niche technologies to mine manganese nodules from deep sea, has developed several deep sea systems like remotely operable vehicles, etc.
• NIOT will be the nodal institution for implementing the proposed Deep Ocean Mission, which encompasses all the areas of Ocean technology like development of manned submersible, offshore large scale desalination, Ocean Thermal Energy Conversion (OTEC), extensive survey of the oceans, acquisition of new ships etc.

NIOT is working towards developing a deep-sea mining system and other technologies for harnessing resources from the ocean to meet India's growing mineral needs and increase self-sufficiency in the near future.
