U.S., Australian navies help Climate Scientists with Research in Pirate-infested Waters


SINGAPORE — Climate scientists have turned to the United States and Australian navies to deploy robotic measuring devices in the Indian Ocean where pirates have made the area too dangerous for researchers.

About one-quarter of the Indian Ocean is now off limits to climate scientists trying to complete a global network of deep ocean devices that gather data crucial to climate change studies and weather forecasts.

"We can't send anybody in that area. Research voyages have been cancelled and I know there's a report of at least one ship that hired an armed escort," said Ann Thresher, an oceanographer with Australia's Commonwealth Scientific and Industrial Research Organization.

"That's pretty extreme when you're talking about climate research," she told Reuters from Hobart.

Thresher said the northwest Indian Ocean played a crucial role in weather patterns in Australia and South Asia, where droughts or floods can cause major disruption to global food prices and trigger large insurance losses.

In particular, data from the Indian Ocean such as salinity and water temperatures and weather observations from ships were crucial for long-range forecasts. It was crucial to fill the gap, otherwise climate scientists were flying blind, she said.

"Without those observations, we can't monitor that as accurately, which means the predictions that scientists make that tell farmers how much rain they are going to get or if there is going to be flooding in Queensland is not as accurate," she said.

The robotic measuring devices, called Argos, are about two metres long and drift between the ocean surface to a depth of about 2,000 metres, before resurfacing to send data via satellite.

About 3,000 Argos have been deployed globally and about 30 countries contribute to the multi-million dollar program that deploys the $19,000 floats.

The Argos measure salinity and temperature and the network monitors how the world's oceans, which soak up large amounts of heat, are responding to a warming world. Oceans shift heat around the globe and drive the world's weather.

The program is heavily reliant on commercial shipping and chartered vessels to deploy Argos globally, but the threat from Somali pirates meant navies were the only option this time.

The devices will be deployed over the next few months in parts of the northwest Indian Ocean.
