The National Undersea Research Program (NURP) is a U.S. government program that operates six facilities for undersea research, including the world's only permanent undersea research facility, Aquarius. The program is operated under the auspices of the Office of Oceanic and Atmospheric Research, a division of the National Oceanic and Atmospheric Administration (NOAA). Each center is funded by a grant from NOAA. Projects are chosen based upon peer review.
