US, India team up to strengthen Indian Ocean observations

Scientists from India and the US have teamed up to strengthen their observation of the vast Indian Ocean, where the atmospheric development has a profound impact on the weather of not only India and the countries in the region, but also on America.

A team of 20 scientists from America's National Oceanic and Atmospheric Administration (NOAA) are landing in Goa next week to hold meeting with India's leading ocean, atmosphere, and fisheries scientists to review their collaboration in this field and decide on the future course of action.

The Madden Julian Oscillation is a phenomenon in the western tropical Indian Ocean which has the most impact on weather pattern of the US, said Craig McLean, NOAA Assistant Administrator for Oceanic and Atmospheric Research and acting NOAA Chief Scientist.

"There's some shallow water near the Seychelles Islands. It heats up, you get evaporation and you get this storm pattern that propagates across the Indian Ocean over Indonesia, across the Pacific and then to the United States," McLean, who is leading a high-powered US delegation to India for the meeting, said.

"In our NOAA climate prediction centre the most prominent data that they use for week two to week four forecasting is the Madden Julian Oscillation," he said. The Madden Julian Oscillation named for Rolland Madden and Paul Julian, two scientists who discovered it in the 1970s.

The Goa meeting of Indian and American scientists would mark a decade of productive collaboration on ocean and atmospheric observations, with life-saving economic benefits for both nations, he said.

A system of buoys deployed jointly by India and the US in the Indian Ocean is at the heart of detecting the Madden-Julian Oscillation, McLean said, adding that this is also key tool for early detection of monsoon in India.

"We are in the midst of an international level of coordination, a second Indian Ocean expedition," he said.

This is being called the International Indian Ocean Expedition Part-II.

As part of this NOAA Shop Ronald H Brown, a blue-water research vessel, is all set to arrive in Goa tomorrow which is part of the Indian Ocean expedition, where it will conduct two major research campaigns to advance ocean observing.

The first campaign will be to sample ocean and atmospheric conditions in the western Indian Ocean, which has not been sampled since 1995. This new data will help scientists better understand how environmental changes in the Indian Ocean may be contributing to sea level rise, expanding ocean dead zones and more intense monsoons in the region,
