NOAA will soon launch a fleet of 15 unmanned gliders in the Caribbean Sea and tropical Atlantic Ocean this hurricane season to collect important oceanic data that could prove useful to forecasters. “If you want to improve prediction of how hurricanes gain strength or weaken as they travel over the ocean, it’s critical to take the ocean’s temperature and measure how salty it is,” said Gustavo Goni, an oceanographer at NOAA’s Atlantic Oceanographic and Meteorological Laboratory who is helping lead the glider research. “Not just at the surface, which we measure with satellites, but down into deeper layers of ocean waters.”
