WHAT ARE OCEAN GLIDERS

  • Autonomous, unmanned underwater vehicle used for ocean science
  • Require little or no human assistance while traveling
  • Uniquely suited for collecting data in remote locations, safely
  • Relatively low cost
  • May be equipped with a wide variety of sensors
  • Monitor temperature, salinity, currents, and other ocean conditions
  • Information creates a more complete picture of what is happening in the ocean, as well as trends

WHAT TYPE OF GLIDERS ARE PROPOSED

  • Having 6-12 months endurance
  • Able to Travel from 3,000 km to 4,500 km
  • About 48 deep Argo floats at 6,000-metre depth at 24 locations and another 150 wave drifters

WHAT IS DEEP OCEAN MISSION

  • Undertaken by the National Institute of Ocean Technology (NIOT)
  • Under Ministry of Earth Sciences
  • Approved in 2021
  • India’s first unique manned ocean mission
  • Aims to send men into the deep sea in a submersible vehicle for deep-sea ocean exploration and mining of rare minerals
  • Resources such as polymetallic manganese nodules, Gas hydrates, hydrothermal sulfides, and cobalt crusts will be explored which are usually located at a depth between 1000 to 5500 meters.
  • India has been allocated a site of 75,000sq km in the Central Indian Ocean Basin by the International Sea Bed Authority (ISA) for the exploration of polymetallic nodules from the seabed in a 15-year contract.
  • The estimated resource potential of polymetallic nodules is 380 million tonnes through preliminary studies. Major components in these nodules are manganese, nickel, copper, and cobalt.
