Deep Ocean Mission (informally known as Samudrayaan

polymetallic nodules, which are composed of minerals like manganese, nickel, cobalt, copper and iron hydroxide.[12] The metals can be used in the manufacturing of electronic devices, smartphones, batteries and solar panels.[12]

India has been allocated a 75,000 km2 (29,000 sq mi) site in the Central Indian Ocean Basin by the

₹4077 crore for a of 5-year period and this will be implemented in a phase-wise process.[14] The first phase of the project is from 2021 to 2024.[15] Under its sub-project informally dubbed Samudrayaan, India has aims to send three people into deep sea up to a depth of 6 km (3.7 mi) in Indian Ocean in an indigenous deep sea submersible having an endurance of 72 hours.[16]

History

The study of the ocean in

polymetallic nodules (PMN) initiated at CSIR-NIO with the collection of the first nodule sample from Arabian Sea
on board the first research vessel Gaveshani on 26 January 1981.

The International Seabed Authority (ISA), an autonomous international organisation established under the 1982 United Nations Convention on the Law of the Sea, allotted the area for deep-sea mining. India was the first country to receive the status of a 'Pioneer Investor' in 1987 and was given an area of about 1.5 lakh km2 in the Central Indian Ocean Basin (CIOB) for nodule exploration.

This was based on the extensive survey carried out by the scientists of CSIR-NIO on several research ships leading to the allocation of an area of 150,000 km2 (58,000 sq mi) to the country with exclusive right under the UN law of the sea.

India was the first country in the world, to have sponsored the exploration of deep sea mineral viz polymetallic nodules, in the central Indian Ocean basin in 1987.

In 2002, India signed a contract with the ISA and after complete resource analysis of the seabed 50% was surrendered and the country retained an area of 75,000 km2.

Further studies have helped narrow the mining area to 18,000 km2 which will be the ‘First Generation Mine-site’.

Background

India has an Exclusive Economic Zone allocated 2,200,000 km2 (850,000 sq mi) which is unexplored and unutilised.

Exclusive Economic zones are boundaries prescribed by the United Nations Convention on the law of the sea which give the rights to a state regarding the exploration and use of marine resources.

India has been allocated a site of 75,000 km2 (29,000 sq mi) in Central Indian Ocean Basin (CIOB) by the

manganese hydroxide
.

It has been estimated that 380 million metric tonnes of PMN are available at the bottom of the seas in the central Indian Ocean.

It is estimated that 10% of recovery of that can meet India's energy requirement for next 100 years.

Goal and objectives

The centre has drawn up a five-year plan, with a cost of ₹4,077 crore, to mine, research and study about the ocean floor.

The objectives of the plan include research work that can result in formation of a roadmap on climate change and help in developing a desalination plant powered by OTEC energy.

One of the key projects which can enable the above said research is the creation of a submersible vehicle that can explore depths of at least 6,000 m (20,000 ft).

Progress made

Indian Space Research Organisation developed the design of a crewed submersible capsule capable of travelling 6,000 m deep for the mission. The development was announced on the sidelines of the silver jubilee celebrations of the National Institute of Ocean Technology.[17] A deep-submergence vehicle named Matsya 6000 is under development. The first uncrewed trial of the vehicle was conducted on 27 October 2021 where the personnel sphere was lowered up to a depth of 600 m, off the coast of Chennai. The trial was successful and received the certification for further development. Following the success of the trial, the Samudrayaan program was formally launched on 29 October 2021.[18][19]
