JI_250M_LCC_WGS84.TIF - Johnston Atoll U.S. EEZ GLORIA sidescan-sonar composite mosaic (LCC, 250 m, WGS84)

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 surveys during that time period, and conducted in succession from 6 December 1990 to 21 February 1991, focused on the U.S. Exclusive Economic Zone surrounding the Johnston Atoll. The results of these surveys were 16 digital mosaics of approximately a 2 degree by 2 degree area with a 50-meter pixel resolution.
