PR_Q01.TIF - Puerto Rico U.S. EEZ GLORIA sidescan-sonar data mosaic (1 of 9) (ACEA, 50 m, Clarke1866)

The Puerto Rico U.S. EEZ study area includes the seafloor between the island of Puerto Rico and the Puerto Rico Trench floor and extends west to Mona Canyon and east to the U.S. Virgin Islands. South of the islands, it covers parts of the Muertos Trough and the Venezuelan Basin. The study area includes the seafloor between the island of Puerto Rico and the Puerto Rico Trench floor and extends west to Mona Canyon and east to the U.S. Virgin Islands. South of the islands, it covers parts of the Muertos Trough and the Venezuelan Basin. As in earlier EEZ reconnaissance surveys, the USGS utilized the GLORIA (Geological LOng-Range Inclined Asdic) sidescan-sonar system to complete the geologic mapping. The collected GLORIA data were processed and digitally mosaicked to produce continuous imagery of the seafloor. A total of 9 digital mosaics of approximately a 2 degree by 2 degree (or smaller) area with a 50-meter pixel resolution were completed for the Puerto Rico U.S. EEZ.

美国专属经济区（Exclusive Economic Zone, EEZ）波多黎各研究区域涵盖波多黎各岛与波多黎各海沟床之间的海底区域，其范围西至莫纳峡谷（Mona Canyon），东至美属维尔京群岛。在群岛以南区域，该研究区涵盖穆埃托斯海槽（Muertos Trough）与委内瑞拉盆地（Venezuelan Basin）的部分区域。美国专属经济区波多黎各研究区域涵盖波多黎各岛与波多黎各海沟床之间的海底区域，其范围西至莫纳峡谷，东至美属维尔京群岛。在群岛以南区域，该研究区涵盖穆埃托斯海槽与委内瑞拉盆地的部分区域。与此前的专属经济区普查勘测工作一致，美国地质调查局（United States Geological Survey, USGS）采用GLORIA（地质远程倾斜声呐成像系统，Geological LOng-Range Inclined Asdic）侧扫声呐系统完成了本次地质填图工作。所采集的GLORIA数据经过处理与数字镶嵌作业，生成了连续的海底全景影像。针对美国专属经济区波多黎各海域，美国地质调查局共完成9幅数字镶嵌影像，单幅影像覆盖面积约为2°×2°（或更小），像素分辨率为50米。
