Seabed Resident Event Profiler

  • Scientists at CSIR-National Institute of Oceanography (NIO) have developed a robotic platform, Seabed Resident Event Profiler (SREP).
  • This is a platform that is capable of being stationed at any water depth from 0-200 metres to track the oceanic processes.
  • The robot has been designed 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.
  • The SREP robot has been designed particularly 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 also brings the nutrient-rich water to the surface and enhances the biological productivity of the region.
  • Several sensors attached to SREP is capable of detecting the conditions associated with upwelling such as low temperature, low oxygen, high nutrients, and changes in density patterns etc.
  • This enables SREP to effectively track upwelling during June to September.
  • Upwelling is an important phenomenon for the ecosystem sustenance and fishery.
  • Similarly, since south-west monsoon forms the backbone of the country’s economy, knowing the conditions for its onset forms one of the major goals of Seabed Resident Event Profiler.
  • The robot in its final configuration will be capable of sitting on the seabed for 100 days continuously to track the oceanic processes in the upcoming monsoon season.
