World’s first locomotion trials of the Deep-Sea Mining System in the Central Indian Ocean

In News 
  • Union Minister of State (Independent Charge) Science & Technology;Dr Jitendra Singh presented National Science Awards and lauded India's "Deep Sea" initiatives.
  • He also complimented the scientists for conducting world’s first locomotion trials of the Deep-Sea Mining System in the Central Indian Ocean at depth of 5270 meters.
Fully Automated Coastal observation System 
  • Dr Jitendra Singh launched a first-of-its-kind and state-of-art fully automated buoy-based coastal observation and water quality nowcasting system for the Indian Ocean developed by Indian National Centre for Ocean Information Services (INCOIS), Hyderabad.
  • The system includes high-end sensors onboard an automated buoy integrated to a coastal observatory located in Kochi.
  • The system will benefit various stakeholders, including coastal dwellers, fisherfolk, maritime industry, researchers and agencies dealing with pollution, tourism, fisheries, and the coastal environment.
  • It will provide real-time data of 19 water quality-related measurements such as temperature, salinity, dissolved oxygen, turbidity, etc., which will help generate accurate nowcasts about coastal water quality, improve indices of coastal ecosystems’ health, and calibrate and validate sensors onboard satellites such as Oceansat-III.
  • INCOIS will provide this data free of cost to the public through a dedicated website. Another such observatory in Vishakhapatnam is imminent.
Deep Ocean Mission 
  • The focus of the mission will be on deep-sea mining, ocean climate change advisory services, underwater vehicles and underwater robotics related technologies.
  • The Ministry of Earth Sciences (MoES) will be the nodal Ministry implementing this multi-institutional 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 developed for mining polymetallic nodules at those depths in the central Indian Ocean.
  • Development of Ocean Climate Change Advisory Services.
  • Development of a component for searching deep sea flora and fauna, including microbes, and studying ways to sustainably utilise them.
  • It will also have a component to explore and identify potential sources of hydrothermal minerals that are sources of precious metals formed from the earth’s crust along the Indian Ocean mid-oceanic ridges.
