A Shift from Ocean Form ga to Real-time Data India’s 6th Wave Rider Buoy .eployed in Kodiakkarai Coast
MAKING THE INDIAN COASTLINE SAFE
India’s 7,500 km-long coastline will soon be equipped with security radars at vantage points to detect movement of suspicious vessels along the country’s maritime boundary. The first two radars will be formally commissioned in Porbandar in Gujarat and the Mumbal region. In all, 36 radars will be installed in the mainland, six in the Lakshadweep and Minicoy Islands and four in Andaman and Nicobar. The first phase of the coastal radar network, on both the west and east coasts is projected to complete in the next two months, The two-phase network, which will be a chain of radars all along India’s coastline, is a crucial component of the coastal security mechanism, which aims at monitoring and identification of maritime traffic. This step to strengthen the coastal security network was taken. in the wake of the 26/11 terror attacks in Mumbai in 2008.
Costal Security review meeting are held regularly between the Defense minister and
Navy chief to review the safety of the Indian coasts. -___ r
The wave rider buoy, jointly under the aegis of the M.S. Swaminathan Research Foundation and INCOIS, Hyderabad, deployed off the Kodiakkarai coast to provide satellite-enabled, real-time ocean state forecast to fisherfolk. It will mark a significant shift in the critical ocean state information from forecast to real-time data for stakeholders.
Wave rider buoy is a sea-monitoring system integrated with INSAT. The buoy will gauge sea conditions, from wave patterns, swells and depths to sea temperature, and transmit the data as real-time information via satellite to the earth stations. Here, INCOIS and MSSRF will be the receiving stations of the teal-time information from the buoys. The processed date will include ocean weather forecasts on high wave alerts and cyclonic surges.
The ocean state information involves an array of critical inputs on wave pattern and swell, sea temperature, wave speed, wind speed, water currents, including cyclone alerts, in three-hour intervals as real-time data. This is an upgraded departure from the forecast format to real-time reading of the ocean state by the Village Resource Center of the MSSRF for fisherfolk, as primary stakeholders.
The Village Resource Centre, MSSRF, said the buoy has been anchored by a moor on the seabed, and the sea wave data is gauged by an accelerometer mounted on the buoy. The upheavals of the buoy register the wave patterns.
The buoy will add value for the entire Palk Strait due to its location, providing better accuracy. Earlier, the radial coverage was 11.5 km per unit.
Now, the wave ride buoy is set to cover a radial distance of 1 km per unit, making it location specific, locally relevant owing to definitive information.
This also marks a significant shift from earlier forecasts for a six-hour period to real-time information based on minute by minute information transmission in local language. The buoy is equipped with two antennae, one as a receptor to transmit signals via INSAT to INCOIS and other to the local receiver station in VRC located at Vedaranyam. The buoy has been deployed 10 km off the Vedaranyam coast and at a depth of 10 metres.
Technical support and financial support for deployment has been provided by INCO1S; and deployment facilitated by the National Institute of Oceanography. INCOIS has also provided the strategic and training support io the MSSRF in real time forecast dissemination to fisherfolk. The Kodiakkarai buoy will be first in Tamil Nadu and sixth in the country after Port Blair, Kollam, Vishakapattinam, Ratnagiri, Puducherry, and Karwar.
The buoy presently deployed at Port Blair provides for lesser accuracy due to the gulf and bay-riddled shoreline of the Palk Strait. Kodiakkarai, with its open coast, will enable the wave rider buoy to transmit accurate information on wave forecasts for the entire Palk Bay region_ This is set to provide critical wave forecast and ocean state information for fisherfolk of Nagapattinarn, Pudukottai, Thanjav–w–, Tiruvarur, and Rameswaram.
The MSSRF will disseminate OSF (Ocean State Forecast) information through its Village Resource Centers and Village Knowledge Centers, and will be clubbed with its existing helpline on ocean state forecasts on 9282442312
