India's Deep-Sea Exploration and Ocean Resource Development
Union Minister Dr. Jitendra Singh announced India's ambitious plans for deep-ocean exploration and research during the Indo-Pacific Regional Dialogue 2026. The National Institute of Ocean Technology (NIOT) in Chennai has developed capabilities to conduct trials at depths of 5,000 to 6,000 metres in the Central Indian Ocean Basin, using the Ocean Mineral Explorer for high-resolution exploration of hydrothermal sulphide deposits, several of which have already been identified.
The Samudrayaan Mission involves the Matsya submersible designed to carry three aquanauts to depths of 5,000–6,000 metres, with India targeting its first human deep-sea mission to reach 6,000 metres by 2028. This represents a significant milestone in India's indigenous deep-ocean exploration program, drawing parallels with the Gaganyaan human spaceflight mission to demonstrate the country's growing scientific and technological capabilities.
Integrated Scientific Approach and Economic Value
India's approach combines multiple scientific disciplines including ocean sciences, space technology, nuclear science, geology, electronics, and robotics. Space-based capabilities support ocean research through dedicated satellites monitoring ocean color, sea-surface temperature, and wind vectors. Nuclear technology contributes to seawater desalination, with examples including the Kalpakkam plant supported by Bhabha Atomic Research Centre and a low-temperature desalination facility in Lakshadweep developed by the Ministry of Earth Sciences.
Deep ocean resources are identified as a major source of economic value addition for achieving the Viksit Bharat 2047 vision. The government emphasizes that significant economic potential lies in unexplored or underexplored resources, particularly in the deep ocean.
Funding and International Cooperation
The government has established the Anusandhan National Research Foundation and announced a ₹1 lakh crore Research, Development and Innovation (RDI) Fund to accelerate private-sector participation. The RDI Fund operates on a 50:50 equity-based approach, encouraging private-sector stakeholders and investors to participate alongside government in emerging research areas.
International cooperation is emphasized through the principle of 'One Ocean, Shared Knowledge and Equitable Prosperity'. Key priorities include closing observational gaps, improving extreme event forecasting, establishing regional climate services partnerships, promoting accessible ocean technologies, advancing deep-ocean research, and strengthening conservation and equitable use of ocean resources.
Additional Initiatives and Future Directions
The government has initiated an annual ocean-cleanliness campaign involving coastal district administrations, Indian Navy, Indian Coast Guard, NGOs, and other stakeholders. For clean energy in maritime transport, India is exploring nuclear-powered vessels following the opening of the nuclear sector to private participation under the SHANTI Act, with a target of achieving 100 GW of nuclear energy capacity by 2047. The Deep Ocean Mission is also exploring renewable energy generation from oceans through solar panels, ocean winds, and temperature or energy gradients.
