Deep Ocean Mission

The Cabinet Committee on Economic Affairs has approved the proposal of the Ministry of Earth Sciences (MoES) on the Deep Ocean Mission (DOM).
The blueprint of the DOM to explore the deep recesses of the ocean was unveiled in 2018. Earlier, MoES had also rolled out the draft Blue Economy Policy.

The cost of the Mission has been estimated at Rs. 4,077 crore over a five-year period and will be implemented in phases. MoES will be the nodal ministry implementing this multi-institutional ambitious mission.
It will be a mission mode project to support the Blue Economy Initiatives of the Government of India.
Blue Economy is the sustainable use of ocean resources for economic growth, improved livelihoods and jobs, and ocean ecosystem health.
The technology and expertise needed in such missions is now available with only five countries – US, Russia, France, Japan and China.
India will now be the sixth country to have it. Major Components of mission:

A manned submersible will be developed to carry three people to a depth of 6,000 metres in the ocean with a suite of scientific sensors and tools.
An Integrated Mining System will be also developed for mining polymetallic nodules at those depths in the central Indian Ocean.
Polymetallic nodules are rocks scattered on the seabed containing iron, manganese, nickel and cobalt.
The exploration studies of minerals will pave the way for commercial exploitation in the near future, as and when commercial exploitation code is evolved by the International Seabed Authority, an United Nations (UN) organization.

It entails developing a suite of observations and models to understand and provide future projections of important climate variables on seasonal to decadal time scales.
Technological Innovations for Exploration and Conservation of Deep-sea Biodiversity:
Bio-prospecting of deep sea flora and fauna including microbes and studies on sustainable utilization of deep sea bio-resources will be the main focus.

It will explore and identify potential sites of multi-metal Hydrothermal Sulphides mineralization along the Indian Ocean mid-oceanic ridges.

Studies and detailed engineering design for offshore Ocean Thermal Energy Conversion (OTEC) powered desalination plants are envisaged in this proof of concept proposal.
OTEC is a technology which uses ocean temperature differences from the surface to depths lower than 1,000 meters, to extract energy.

It is aimed at the development of human capacity and enterprise in ocean biology and engineering.
It will translate research into industrial application and product development through on-site business incubator facilities.

Oceans, which cover 70% of the globe, remain a key part of our life. About 95% of the Deep Ocean remains unexplored.
Three sides of India are surrounded by the oceans and around 30% of the country’s population living in coastal areas, the ocean is a major economic factor supporting fisheries and aquaculture, tourism, livelihoods and blue trade.
India has a unique maritime position. Its 7517 km long coastline is home to nine coastal states and 1382 islands.
The Government of India’s Vision of New India by 2030 announced in February 2019 highlighted the Blue Economy as one of the ten core dimensions of growth.
Oceans are also a storehouse of food, energy, minerals, medicines, modulator of weather and climate and underpin life on Earth.
Considering the importance of the oceans on sustainability, the UN has declared the decade, 2021-2030 as the Decade of Ocean Science for Sustainable Development.
