The ‘Samudrayaan’ is a part of the Ministry of
Earth Sciences’ pilot project for deep ocean mining for rare minerals.
The project proposes to send a submersible
vehicle with three persons to a depth of about 6000 metres to carry out deep
The project is being undertaken by National
Institute of Ocean Technology.
Recently, the Indian government has given
approval to the Deep Ocean Mission (DOM). The mission proposes to explore Deep
Ocean similar to space exploration started by ISRO.
Key areas of the mission are: a) Deep-sea
mining: exploitation of polymetallic nodules(PMN), b) Ocean climate change
advisory services, c) Underwater vehicles, d) Underwater robotics related
Two key projects have been planned under the
Mission: a) Desalination plant powered by tidal energy, b) Submersible vehicle
equipped to explore depths of at least 6,000 metres.
The mission will be led by the Union Earth
Sciences Ministry. It will be a five-year mission and is expected to commence
from October 31, 2019.
India has been allocated a site of 75,000 sq km
in the Central Indian Ocean Basin by the International Sea Bed Authority for
exploration of polymetallic nodules from seabed.
The estimated resource of polymetallic nodules
is about 380 million tonnes, containing 4.7 million tonnes of nickel, 4.29
million tonnes of copper and 0.55 million tonnes of cobalt and 92.59 million
tonnes of manganese.
