Samudrayaan Mission: India set to dive to explore marine biodiversity

Concept :

In order to explore the potential of the seabed, the National Institute of Ocean Technology’s (NIOT) MATSYA 6000 will dive 6,000-meter into the Indian Ocean under the Samudrayaan mission.

Samudrayaan Mission (India’s Deep Ocean Mission)

Samudrayaan, or the journey into the sea, is a mission launched in 2021 to unlock the mysteries of the deep ocean for mineral resources and develop deep sea technologies for sustainable use of ocean resources.
A sub-component of India’s Deep-Sea Mission, the Samudrayaan mission aimed at supporting the Blue Economy initiatives of the Indian government by developing niche technology, vehicles to carry out subsea activities.
The MoES is the nodal ministry to implement this multi-institutional ambitious mission.
The estimated cost of the mission will be Rs 4077 crore for a period of 5 years to be implemented in a phase-wise manner – cost for the first phase (2021-2024) would be Rs 2823.4 crore.
Indian Space Research Organization (ISRO), Indian Institute of Tropical Meteorology (Pune) and Defence Research and Development Organisation (DRDO) will actively participate in this mission.
It was conceptualised based on the forthcoming Gaganyaan mission – ISRO’s attempt at a crewed mission into space – expected in late 2024 or 2025.

MATSYA 6000

It is a manned submersible vehicle developed by NIOT under the Samudrayaan mission to facilitate humans in the deep ocean in exploring mineral resources like Nickel, Cobalt, Rare Earths, Manganese, etc.
Expected to be launched in 2024-25, it would make India only one among six countries (US, Russia, Japan, France, and China) to have piloted a crewed under-sea expedition beyond 5,000 metres.
MATSYA-6000 is a spherical, titanium hull (made by ISRO) equipped with life-support, capable of floating underwater and collecting soil and rock samples from the seabed with attached robotic arms.
Three navigators, over a fortnight and about 1,500 km away from Kanyakumari will undertake multiple trips – each lasting about 12 hours (descent and ascent will be 8 hours and rest is exploration, surveying and scientific activity).
At a depth of 6,000 metres, the weight of water would be nearly 600 times that at sea level which makes the pressurised hull the most important component of the submersible.
About 60% of the submersible was manufactured in India. Components such as cameras, sensors, and communication systems were bought from international vendors.
Over the years, NIOT has consulted with crewed-submersible experts from several countries – Japan, Russia, France and the know-how to ensure a safe ascent and descent.

National Institute of Ocean Technology

Established in 1993 as an autonomous society under the Ministry of Earth Sciences (MoES), NIOT is based in Chennai.
The major aim of starting NIOT was to develop reliable indigenous technologies to solve various engineering problems associated with harvesting of non-living and living resources in India’s exclusive economic zone (EEZ).

Significance

India’s seabed and the relevant zones with economic potential are not deeper than 6,000 metres.
India’s energy needs and increasing competition to harness ocean resources are the key thrust for the Samudrayaan mission.
The International Seabed Authority (ISA) has allocated about 75,0000 square kilometres in the Central Indian Ocean Basin (CIOB) to conduct exploratory mining (of polymetallic nodules).
Note :Just this month the UN passed the High Seas treaty (India too has committed to this) that seeks to protect 30% of the world’s ocean by 2030.
