  • National Institute of Ocean Technology (NIOT), an autonomous institute under MoES, is entrusted with the responsibility to develop various technologies related to the Samudrayaan Mission.

MATSYA 6000

  • It is an indigenously developed manned submersible vehicle.
  • It will facilitate the MoES in conducting deep ocean exploration of resources such as gas hydrates, polymetallic manganese nodules, hydro-thermal sulfides, and cobalt crusts which are located at an approximate depth between 1000 and 5500 metres.
  • Polymetallic Nodules, also called manganese nodules, are mineral concretions on the sea bottom formed of concentric layers of iron and manganese hydroxides around a core.
