HW2_Q50.TIF - Hawaii II - Central Hawaii U.S. EEZ GLORIA sidescan-sonar data mosaic (21 of 24) (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 1988 through 1991, the USGS and IOS (Institute of Oceanographic Sciences, U.K.) scientists conducted several surveys within the U.S. EEZ off Hawaii. Nine surveys during that time period focused on the central Hawaii region. The results of these surveys were 24 digital mosaics 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一项研究项目，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，对全美专属经济区（U.S. Exclusive Economic Zone, EEZ）开展全域调研。1988年至1991年期间，USGS与英国海洋科学研究所（Institute of Oceanographic Sciences, U.K., IOS）的科研人员在美国夏威夷外海专属经济区内完成多轮勘测，其中9轮勘测聚焦夏威夷中部海域。本次勘测的最终成果为24幅数字镶嵌图，单幅覆盖范围约为2°×2°，像素分辨率达50米。
