Description In 1984, the U.S. Geological Survey (USGS), Office of Marine Geology, launched a program using the Geological LOng-Range Inclined Asdic (GLORIA) sidescan-sonar system to study the entire U.S. Exclusive Economic Zone (EEZ). From December 1990 through February 1991, the USGS and IOS (Institute of Oceanographic Sciences, U.K.) scientists conducted three surveys within the Johnston Atoll U.S. EEZ surrounding Johnston Island. The results of these surveys were 16 digital mosaics of a 2 degree by 2 degree area with a 50-meter pixel resolution. [More]
