India to explore deep sea technologies for sustainable use of ocean resources

The Cabinet Committee on Economic Affairs (CCEA) has approved a proposal of the ministry of earth sciences on a "Deep Ocean Mission", with a view to explore deep ocean for resources and develop deep sea technologies for sustainable use of ocean resources. 

The estimated cost of the mission will be Rs4,077 crore for a period of 5 years to be implemented in a phase-wise manner. The estimated cost for the first phase for the 3 years (2021-2024) would be Rs2,823.4 crore. Deep Ocean Mission will be a mission mode project to support the Blue Economy Initiatives of the Government of India. Ministry of earth sciences (MoES) will be the nodal ministry implementing this multi-institutional ambitious mission.
The Deep Ocean Mission will aim at development of technologies for deep sea mining, and manned submersible. A manned submersible will be developed to carry three people to a depth of 6,000 metres in the ocean with suite of scientific sensors and tools. Only a very few countries have acquired this capability. An integrated mining system will be also developed for mining polymetallic nodules from 6,000 m depth in the central Indian Ocean. The exploration studies of minerals will pave way for the commercial exploitation in the near future, as and when commercial exploitation code is evolved by the International Seabed Authority, an UN organisation. This component will help the Blue Economy priority area of exploring and harnessing of deep sea minerals and energy.
A suite of observations and models will be developed to understand and provide future projections of important climate variables on seasonal to decadal time scales under this proof of concept component. This component will support the Blue Economy priority area of coastal tourism.
Bio-prospecting of deep sea flora and fauna, including microbes and studies on sustainable utilisation of deep sea bio-resources will be the main focus. This component will support the Blue Economy priority area of marine fisheries and allied services.
The objective of deep ocean survey and exploration is to explore and identify potential sites of multi-metal hydrothermal sulphides mineralisation along the Indian Ocean mid-oceanic ridges. This component will additionally support the Blue Economy priority area of deep sea exploration of ocean resources.
Studies and detailed engineering design for offshore Ocean Thermal Energy Conversion (OTEC) powered desalination plant are envisaged in this proof of concept proposal. This component will support the Blue Economy priority area of off-shore energy development.
The proposed advanced marine station for ocean biology is aimed as development of human capacity and enterprise in ocean biology and engineering. This component will translate research into industrial application and product development through on-site business incubator facilities. This component will support the Blue Economy priority area of marine biology, blue trade and blue manufacturing.
The technologies required for deep sea mining have strategic implications and are not commercially available. Hence, attempts will be made to indigenise technologies by collaborating with leading institutes and private industries. A research vessel for deep ocean exploration would be built in an Indian shipyard which would create employment opportunities. This mission is also directed towards capacity development in marine biology, which will provide job opportunities in Indian industries. In addition, design, development and fabrication of specialised equipment, ships and setting up of required infrastructure are expected to spur the growth of the Indian industry, especially the MSME and start-ups.
Oceans, which cover 70 per cent of the globe, remain a key part of our life. About 95 per cent of the deep ocean remains unexplored. For India, with its three sides surrounded by the oceans and around 30 per cent of the country's population living in coastal areas, ocean is a major economic factor supporting fisheries and aquaculture, tourism, livelihoods and blue trade. Oceans are also storehouse of food, energy, minerals, medicines, modulator of weather and climate and underpin life on Earth. Considering importance of the oceans on sustainability, the United Nations (UN) has declared the decade 2021-2030 as the Decade of Ocean Science for Sustainable Development. 
India has a unique maritime position. Its 7,517 km long coastline is home to nine coastal states and 1,382 islands. The Government of India's Vision of New India by 2030 enunciated in February 2019 highlighted the blue economy as one of the ten core dimensions of growth.
