HW3_Q57.TIF - Hawaii III - Northwestern Hawaii U.S. EEZ GLORIA sidescan-sonar data mosaic (5 of 22) (LCC, 50 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 1989 through 1991, the USGS and IOS (Institute of Oceanographic Sciences, U.K.) scientists conducted several surveys within the EEZ off Hawaii. Six surveys during that time period focused on the northwestern Hawaii region. The results of these surveys were 22 digital mosaics of approximately of approximately a 2 degree by 2 degree area 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了一项研究项目，采用地质远程倾斜侧扫声呐（Geological LOng-Range Inclined Asdic, GLORIA）系统，对美国全境专属经济区（Exclusive Economic Zone, EEZ）开展系统性研究。1989年至1991年间，USGS与英国海洋科学研究所（Institute of Oceanographic Sciences, U.K., IOS）的科研人员在夏威夷外海的专属经济区内完成了多次勘测，其中6次勘测的研究区域聚焦夏威夷西北部海域。本次系列勘测的成果为22幅数字镶嵌图，单幅覆盖面积约为2度×2度，像素分辨率达50米。
