KP_250M_LCC_WGS84.TIF - Kingman Reef and Palmyra 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). 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.

1984年，美国地质调查局（U.S. Geological Survey, USGS）海洋地质办公室启动一项计划，采用地质远程倾斜声呐成像系统（Geological LOng-Range Inclined Asdic, GLORIA）侧扫声呐系统，对美国全域专属经济区（U.S. Exclusive Economic Zone, EEZ）开展系统性研究。1991年2月24日至3月25日的为期一个月内，美国地质调查局与IOS（英国海洋科学研究所，Institute of Oceanographic Sciences, U.K.）的科研人员在金曼礁（Kingman Reef）及帕尔米拉环礁（Palmyra Atoll）所属美国专属经济区内完成单次勘测。本次勘测聚焦金曼礁与帕尔米拉环礁周边的美国专属经济区，但遗憾的是，该区域西南三分之一的范围未能完成成像。本次单次勘测最终产出7幅像素分辨率为50米的数字镶嵌图。
