A manned submersible will be developed to carry three people to a depth of 6,000 metres in the ocean
In 2016, India was awarded a 15-year contract to explore an area of 75,000 square kilometres for mining polymetallic nodules from the Central Indian Ocean Basin at depths of 5,000-6,000 metres.
The other components of the mission include developing ocean climate change advisory services and designing offshore Ocean Thermal Energy Conversion (OTEC) powered desalination plants.

Oceans are storehouses of food, energy, minerals, and medicines.
It also modulates weather and climate.
Deep-sea mining involves extracting ores rich in cobalt, manganese, zinc and other rare metals from the sea floor.
They contain critical minerals needed to build batteries for electric vehicles and renewable energy capacity, smartphones and laptops.
