Climate scientists are teaming up with the U.S. and Australian navies to deploy weather-tracking probes in areas of the Indian Ocean where pirates are active. The scientists have asked the navies to release six-foot-long robotic Argo probes, which each cost around $19,000, to gather information on salinity and water temperatures. The devices help predict weather patterns and track climate change in the Indian Ocean, information critical to Australian meteorologists as they estimate the country's rainfall and flood risks. In the past, scientists have used chartered ships and commercial vessels to deploy the probes, but the threat of pirate attacks have left unarmed carries vulnerable to attack in the northwest Indian Ocean. Worldwide, about 3,000 Argos are already at sea.
