Subject: Economy

Context: India will soon launch an ambitious ‘Deep Ocean Mission’ that envisages exploration of minerals, energy and marine diversity of the underwater world, a vast part of which still remains unexplored.

Concept:

  • The focus of the mission will be on deep-sea mining, ocean climate change advisory services, underwater vehicles and underwater robotics related technologies.
  • Two key projects planned in the ‘Deep Ocean Mission’ report include a desalination plant powered by tidal energy and a submersible vehicle that can explore depths of at least 6,000 metres.

Significance of the Mission:

  • The ‘Deep Ocean Mission’ plan will enable India to develop capabilities to exploit resources in the Central Indian Ocean Basin (CIOB).
  • India has been allotted 75,000 square kilometres in the Central Indian Ocean Basin (CIOB) by UN International Sea Bed Authority for exploration of poly-metallic nodules. CIOB reserves contain deposits of metals like iron, manganese, nickel and cobalt.

Potential:

  • It is envisaged that 10% of recovery of that large reserve can meet the energy requirement of India for the next 100 years. It has been estimated that 380 million metric tonnes of polymetallic nodules are available at the bottom of the seas in the Central Indian Ocean.

Polymetallic nodules

  • Polymetallic nodules (also known as manganese nodules) are potato-shaped, largely porous nodules found in abundance carpeting the sea floor of world oceans in deep sea.
  • Composition: Besides manganese and iron, they contain nickel, copper, cobalt, lead, molybdenum, cadmium, vanadium, titanium, of which nickel, cobalt and copper are considered to be of economic and strategic importance.
