National institute of Oceanography has developed a robotic platform, Seabed Resident Event Profiler which is capable of being stationed at any water depth from 0 - 200 meters to track the oceanic processes. It has been made to regularly record the water column information at every 10 to 25 cm during every profile four times a day. The robot was tested during the recent voyage of RV Sindhu Sadhana, the latest state of the art research vessel of NIO.

What is the significance of the robot?

  • It has been designed to carry out studies related to the monsoon, global climate and upwelling.
  • Upwelling is a phenomenon associated with the monsoon that sees the migration of deep sea oxygen minimum zone (OMZ) towards the coast.
  • It brings the water which is nutrient rich to the surface and it enhances the biological productivity of the region
  • The sensors attached are able to detect the conditions with upwelling such as low temperature, low oxygen, high nutrients, and changes in density patterns etc.
  • This has been enabling the SREP to effectively track upwelling during June to September.
  • Upwelling is an important phenomenon for the ecosystem sustenance and fishery.
  • Since the south-west monsoon has been a backbone of the country’s economy, knowing the conditions for its onset forms one of the major goals of SREP.
  • It shall be able to track oceanic processes in the upcoming monsoon season.
