Chennai:
Seven scientists from the city’s National Institute of
Ocean Technology (NIOT), an autonomous organization under Ministry of Earth
Sciences, won prestigious National Geo Science Award for the successful
development of a Remotely Operable Vehicle (ROV) to unravel many mysteries of
ocean basins in India.
NIOT director Dr M A Atmanand, project director Dr G A
Ramadass, Dr S Ramesh, AN Subramanian, Dr D Sathianarayanan, R Ramesh, and G
Harikrishnan were honoured by the
Ministry of Mines under Oil and Natural Gas Exploration and Disaster
Management categories.
The scientists are brain behind the Remotely Operated
Vehicle (ROV), a remotely controlled underwater vehicle, that can move in the
sea with the help of thrusters and hosts scientific payload like sonars, cameras,
chemical and physical oceanographic sensors.
NIOT spokesman said the technology was deployed at
potential Gas Hydrate site in Krishna Godavari basin of Bay of Bengal with
scientific payload at a depth of 1019 metres during 2009 and at a depth of 5289
m in Poly-metallic Manganese Nodule site in Central Indian Ocean Basin during
April 2010. “India joined a select club of a few nations to own the technology
of this kind,” the spokesman added.
Similarly, two more scientists of NIOT Dr M V
Ramanamurthy and Tata Sudhakar won the award for their work on Tsunami Early
Warning Systems.
The scientists were instrumental in development of
observation network by way of deploying Bottom Pressure Recorders (BPR) in Deep
Ocean and development of numerical model for prediction of Tsunami impact on
coast.
Constant efforts are being made at NIOT to augment the
warning system to cater needs of Regional Advisory Services to Indian Ocean
Countries like inversion of Tsunami data collected by BPR’s to accurately
estimate earthquake source potential, improving of BPR technology to suit
Indian ocean region and development of far field numerical models to predict
the Tsunami propagation across the globe.
