Over the next four months, NOAA scientists will launch unmanned ocean vehicles, called Saildrones, from the Arctic to the tropical Pacific Ocean to help better understand how changes in the ocean are affecting weather, climate, fisheries and marine mammals. The wind and solar-powered research vehicles that resemble a sailboat will travel thousands of miles across the ocean, reaching some areas never before surveyed with such specialized technology.
