Abstract:
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). For a one month period beginning 24 February 1991 and finishing on 25 March 1991, USGS and IOS (Institute of Oceanographic Sciences, U.K.) scientists conducted a single survey within the Kingman Reef and Palmyra Atoll U.S. EEZ. The survey focused on the U.S. Exclusive Economic Zone surrounding the Kingman Reef and Palmyra Atoll. Unfortunately, the southwestern third of this EEZ was not imaged. The results of this single survey was 7 digital mosaics with a 50-meter pixel resolution.
Purpose:
This remote sensing image of the sea-floor is a reduced-resolution (250-meter) composite mosaic of the 7 mosaics created from the Kingman Reef and Palmyra Atoll U.S. EEZ GLORIA sidescan-sonar data.
