BS_Q11.TIF - Bering Sea U.S. EEZ GLORIA sidescan-sonar data mosaic (11 of 30) (LCC, 50 m, Clarke1866)

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 1986 through 1989, the USGS and IOS (Institute of Oceanographic Sciences, U.K.) scientists conducted several surveys within the U.S. EEZ off Alaska. Four surveys during that time period (1986-1987) focused on the Bering Sea region. The results of these surveys were 30 digital mosaics of a 3 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计划，采用地质远程倾斜旁扫声呐（Geological LOng-Range Inclined Asdic, GLORIA）旁扫声呐系统，对美国全境专属经济区（Exclusive Economic Zone, EEZ）开展研究。1986年至1989年间，美国地质调查局与英国海洋科学研究所（Institute of Oceanographic Sciences, U.K., IOS）的科研人员在美国阿拉斯加外海专属经济区内开展多轮勘测。其中1986年至1987年间实施的4轮勘测聚焦白令海区域。本次勘测成果包含30幅覆盖3°×2°区域、像素分辨率为50米的数字镶嵌图。
