James Delgado, director of NOAA\u2019s Maritime Heritage program, added his expertise gathered from years of discovering and documenting wrecks. Vitad Pradith, a physical scientist with NOAA\u2019s Office of Coast Survey, provided technical expertise in using NOAA\u2019s multibeam and sidescan sonar systems &#8212; onboard the NOAA Ship <em>Thomas Jefferson<\/em> &#8212; to locate and image underwater structures.
