PR_Q07.TIF - Puerto Rico U.S. EEZ GLORIA sidescan-sonar data mosaic (7 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. 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.

美属波多黎各专属经济区（Exclusive Economic Zone, EEZ）研究范围涵盖波多黎各岛与波多黎各海沟床之间的海底区域，西延至莫纳峡谷，东至美属维尔京群岛。在群岛以南区域，该范围涵盖穆埃托斯海槽与委内瑞拉海盆的部分区域。与早期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（地质远程倾斜声呐探测器，Geological LOng-Range Inclined Asdic）侧扫声呐系统完成了地质填图。采集得到的GLORIA数据经过处理与数字镶嵌处理，生成了连续的海底影像。本次研究共为美属波多黎各专属经济区生成9幅像素分辨率为50米、覆盖面积约2°×2°（或更小）的数字镶嵌影像。
