In 2016, India signed a 15-year contract with the International Seabed Authority (ISA) for the exploration of polymetallic sulphides at the bottom of the Indian Ocean.
On Tuesday the Indian Government announced that it's developing a manned submersible capable of diving to depths of 600 metres. Delhi is also working on technologies for deep-sea mining and exploration missions to analyse marine biodiversity – a total of $549 million will be spent on the project – called Deep Ocean Mission – over five years.
"The scientists will also develop technologies for deep-sea mining, exploration of deep-sea mineral resources and marine biodiversity, acquisition of a research vessel for ocean exploration, deep-sea observations, and capacity building in marine biology," a government minister stated.
In June, the government approved Deep Ocean Mission to explore the ocean beds for precious minerals and explore flora and fauna. The project has been pending since 2018 and will also involve India's ocean climate change advisory services.

India Gives Nod to Build More Conventional Submarines Amid Power Battle With China in Indian Ocean
The United Nation's International Sea Bed Authority has allotted an area of 75,000 square kilometres in the Central Indian Ocean Basin (CIOB) for the exploitation of polymetallic nodules (PMN). Reportedly, approximately 380 million metric tonnes of polymetallic nodules are present at the bottom of the Central Indian Ocean. These nodules contain precious minerals like manganese, iron, nickel, copper, and cobalt. Currently, the technology required to mine these nodules is not commercially available. 
Around 40 years ago, the Indian research vessel "Gaveshani" recovered the first polymetallic nodule samples from the Indian ocean, becoming a pioneer in the exploration of deep-sea minerals in the process. 
The likes of China, France, Germany, Japan, South Korea, and Russia are also developing their own technology to mine the ocean's depths, and many nations are reportedly testing equipment is shallow waters. 
This type of mining, however, has been flagged by environmentalists, who say it will damage marine biodiversity. According to the International Union for Conservation of Nature (IUCN), species such as whales, tuna, and sharks could be affected by noise, vibrations, and light pollution caused by mining equipment.
