  • Ocean observation systems acquire specific ocean parameters on different spatial and temporal scales.
  • The equipment is of two types - drifters and moored. Examples include moored buoys, drifters, current meters, wave rider buoys, Cargo floats, tide gauges, coastal radars, and acoustic doppler current profilers (ADCP)
  • All the systems except Tide gauges and coastal Radar are deployed in the EEZ of India
  • Ocean observing systems primarily deployed, operated and maintained by four organizations:

    • National Institute of Ocean Technology (NIOT), Chennai
    • National Institute of Oceanography (NIO), Goa
    • Indian National Centre for Ocean Information Services (INCOIS), Hyderabad
    • Survey of India, Dehradun.

Applications

  • Accurate measurements of ocean parameters is used for
  • Research
  • Issue of issue of early warning to tsunami and storm surges
  • Ocean-atmospheric modelling
  • Validation of satellite data.

  • Most important kind of ocean observing system
  • It is a set of buoys at fixed locations in the Exclusive Economic Zone of India (EEZ) for obtaining long-term data.
  • Buoys capable of collecting data on 76 parameters and transmitting in real time through satellites.
  • Moored buoys network augmented to 19 buoy network, deployed in the Arabian Sea and Bay of Bengal.
