India’s First Manned Deep-Sea Mission Set to Unlock Ocean’s Deepest Secrets

Kochi (The Uttam Hindu News): India’s first manned deep-sea mission is set to explore the mysteries of the ocean at depths reaching 6,000 meters. Balaji Ramakrishnan, Director of the National Institute of Ocean Technology (NIOT), announced that the submersible could be launched by the end of 2026. Speaking at the ICAR-Central Marine Fisheries Research Institute (CMFRI), he stated that the mission aims to delve into the secrets of the deep ocean.

Journey to the Deep Sea
The mission will carry three scientists on a deep-sea voyage. NIOT, under the Ministry of Earth Sciences, is the nodal agency for this Deep Ocean Mission. Developed using indigenous technology, the 25-ton, fourth-generation submersible is specially designed to withstand the extreme pressure and temperature of deep-sea environments. It features a titanium hull for enhanced durability. Ramakrishnan called it a potential game-changer for India’s deep-sea research.

Collecting Samples from the Deep

The mission will open new avenues for assessing oceanic resources and exploring the potential for marine tourism. It will also help in collecting crucial samples from the deep-sea zone, allowing scientists to study unique marine life and water characteristics. The launch will follow a phased process.

Testing at 500 Meters by Year-End

A test dive up to 500 meters is planned by the end of this year. The descent will take about four hours, and resurfacing will require the same amount of time.

Innovative Ocean Farming Technology

A new technology is also being developed to support large-scale, open-ocean farming. Currently in the demonstration phase, this system involves electronically monitored fish cages designed for offshore deployment. By leveraging the nutrient-rich deep-sea environment, it aims to optimize fish growth. Equipped with various sensors, the system can remotely monitor fish biomass, growth, movement, and water quality. This technology could play a significant role in ensuring India’s future food security.
