NOAA again will launch four underwater gliders from Puerto Rico and the U.S. Virgin Islands to collect ocean data, and this summer the agency will expand its data pool by collaborating with universities and research institutions in the U.S. and Bermuda that have up to 20 their own gliders in the Gulf of Mexico and the Atlantic.
