DEEP OCEAN MISSION – SCI & TECH

News: Inside India’s ‘Deep Ocean Mission’, a challenge harder than going to space

 

What's in the news?

       The Deep Ocean Mission (DOM) is India’s ambitious quest to explore and harness the depths of the ocean.

 

Key takeaways:

       As part of this initiative, India will, for the first time, embark on a journey to a depth of 6,000 metres in the ocean using an indigenously developed submersible with a three-member crew.

       The mission will require technologies to access and transport tonnes of valuable minerals from the ocean-bed in an environmentally safe manner.

 

MISSION SAMUDRAYAAN - India’s 1st Manned Ocean Mission:

       The project proposes to send a submersible vehicle with 3 persons to a depth of about 6000m to carry out deep underwater studies.

       It is a pilot project of the Ministry of Earth Sciences for deep ocean mining for rare minerals.

       The project is undertaken by the National Institute of Ocean Technology (NIOT), and is in line with ISRO's ambitious 'Gaganyaan' mission.

 

Deep Ocean Mission:

       Deep Ocean Mission aims to explore the deep ocean for resources.

       It also aims to develop deep-sea technologies for sustainable use of ocean resources.

 

Nodal Ministry: Ministry of Earth Sciences (MoES).

 

Duration: 2021-25 (5 years)

 

Components of the Mission:

The Deep Ocean Mission consists of the following six major components such as

1. Development of Technologies for Deep Sea Mining and Manned Submersible:

       A manned submersible will be developed to carry three people to a depth of 6000 metres in the ocean with a suite of scientific sensors and tools.

       For mining Polymetallic Nodules from 6000 m depth in the central Indian Ocean, an Integrated Mining System will also be developed.

2. Development of Ocean Climate Change Advisory Services:

       Models will be developed to understand and provide future projections of important climate variables on seasonal to decadal time scales.

3. 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 under this component.

       Bio-prospecting is defined as a systematic and organized search for useful products derived from bio-resources. It includes plants, microorganisms, animals that can be developed further for commercialization and overall benefits of the society.

4. Deep Ocean Survey and Exploration:

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

5. Energy and freshwater from the Ocean:

       Studies and detailed engineering design for offshore Ocean Thermal Energy Conversion (OTEC) powered desalination plants are being planned under this component.

       OTEC is a processor technology for producing energy by harnessing the temperature differences (thermal gradients) between ocean surface waters and deep ocean waters.

6. Advanced Marine Station for Ocean Biology:

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

 

Significance of the mission:

       Deep Ocean Mission will be a mission mode project to support the Blue Economy Initiatives of the Government of India.

       The technology and expertise needed in such missions are now available in only five countries – US, Russia, France, Japan and China. India will be the sixth country to have it.

 

Significance of the Mission for Indian economy:

1. Capabilities development:

       The ‘Deep Ocean Mission’ plan will enable India to develop capabilities to exploit resources in the Indian Ocean Basin. IOB reserves contain deposits of metals like iron, manganese, nickel and cobalt.

2. Minerals:

       Indian Ocean contain vast amount of minerals, including the cobalt, zinc, manganese and rare earth materials.

       These minerals are needed for electronic industry to make smart phones, laptops and car components etc. This can help Make in India initiative.

3. Energy resources:

       The main energy resources present in Indian Ocean are petroleum and gas hydrates. Petroleum products mainly includes the oil produced from offshore regions.

       Gas hydrates are unusually compact chemical structures made of water and natural gas.

       Deep ocean mission along with these resources would help in exploiting tidal energy and resources.

4. Manganese Nodules and Crusts:

       Manganese nodules contain significant concentrations of manganese, iron and copper, nickel, and cobalt all of which have numerous economic uses.

5. Sustainable development:

       Marine resources from the Indian Ocean would serve as the backbone of India’s economic growth and can help India to become a 5trillion dollar economy by 2022.

       Blue economy, through sustainable use of oceans, has great potential for boosting the economic growth.

6. Employment generation:

       It will provide jobs, improved livelihoods to many. This will help in inclusive growth.

 

7. Climate Change:

       It will help in study Impact of climate change on ocean. This would help India to prepare for any disaster due to climate change.

       Also, Oceans provide an alternate and more cleaner source of energy. It also acts as an important carbon sink. This will help in mitigating climate change.

8. Disaster preparedness:

       Information from deep-ocean exploration can help predict earthquakes and tsunamis.

9. Nation’s security:

       It will play a significant role in the security of the nation as many critical military technologies rely heavily on rare earth elements which are abundant in Ocean.

10. Technological advancements:

       It can also help us in innovating technologies from underwater vehicles to underwater robotics.

11. Health industry:

       Unlocking the mysteries of deep-sea ecosystems can reveal new sources for medical drugs, food, and other products.

 

Sustainable Development Goal (SDG 14), calls to conserve and sustainably use the oceans, seas and marine resources for sustainable development. Thus deep ocean mission is a right step in this direction.
