According SSC Shenoi, director, Indian National Centre for Ocean Information Services (INCOIS), the system will become functional by April this year and the cost of the project is estimated to be at Rs 100 crore.
INCOIS is an autonomous body under the Ministry of Earth Sciences.
Mr Shenoi said that the new ocean data acquisition system, called automated moorings, will do away with the present practice of collecting water samples from sea and studying their pollution levels thereafter.
"This is for the first time India will have such kind of system. In the US you will find it. This is a very effective system in getting the data about the ocean pollution. We will use those data to understand the quality of water," Mr Shenoi told news agency PTI.
He added that the new system will be foolproof.
The project will begin from April once it gets a final nod from the government, he said.
Mr Shenoi said the new system will help in monitoring the pollution level of the ocean water and the impact of climate change.
Anoxic waters are areas of sea water that are depleted of dissolved oxygen.
It will also provide data that will help scientists to understand how the marine system is changing.
Mr Shenoi said sensor-equipped buoys will be placed in six coastal areas of the country. The sensors, placed at the bottom of the buoys, will be attached to the sea bed so that they are not washed away.
The moored ocean buoys will be placed in coastal areas of Digha (West Bengal), Goa, Mumbai, Kochi, Vishakapatanam and Chennai, he said.
"We have already completed our background work. We hope to deploy two buoys by December 2018. We will monitor the reading and functioning and then will place other buoys," he said adding the reading will be observed and decoded using a mathematical model.
It is estimated that more than 80 per cent of the pollution in the ocean is from lands with marine debris, especially plastics, killing thousands of seabirds, mammals and sea turtles every year.
