PR_Q05.TIF - Puerto Rico U.S. EEZ GLORIA sidescan-sonar data mosaic (5 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.

波多黎各美国专属经济区（Exclusive Economic Zone, EEZ）研究区域涵盖波多黎各岛与波多黎各海沟床之间的海底范围，西至莫纳峡谷、东至美属维尔京群岛。在群岛以南区域，该研究区覆盖了穆埃托斯海槽（Muertos Trough）与委内瑞拉盆地的部分海域。与早期专属经济区勘察测绘工作一致，美国地质调查局（United States Geological Survey, USGS）采用GLORIA（地质长程倾斜侧扫声呐系统，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数据经处理与数字镶嵌后，生成了连续的海底影像。针对波多黎各美国专属经济区，共计完成9幅面积约2°×2°（或更小）、像素分辨率为50米的数字镶嵌影像。
