Bathymetric Terrain Model of the Puerto Rico Trench and Northeastern Caribbean Region Compiled by the U.S. Geological Survey From Multibeam Bathymetric Data Collected Between 2002 and 2013 (PRBATHOFR150, Esri Binary Grid, UTM19, WGS 84).

Bathymetric terrain models (BTMs) of seafloor morphology are an important component of marine geological investigations. Advances in technologies of acquiring and processing bathymetric data have facilitated the creation of high-resolution bathymetric surfaces that approach the resolution of those available for onshore investigations. These bathymetric terrain models provide a detailed representation of the Earth's subaqueous surface and when combined with other geophysical and geologic datasets, allow for interpretation of modern and ancient geologic processes.

海底地貌水深地形模型（Bathymetric terrain models，BTMs）是海洋地质调查工作的重要组成部分。伴随水深数据采集与处理技术的迭代升级，高分辨率海底地形曲面的构建技术已日趋成熟，其分辨率已可与陆上地质调查所获取的地形数据精度相媲美。此类水深地形模型能够精细还原地球水下地表的形态特征，若与其他地球物理及地质数据集结合使用，可为现代与古地质作用过程的解译分析提供有力支撑。关于本网格所依托的各份美国地质调查局（United States Geological Survey，USGS）源调查数据（若有USGS科研人员参与相关调查工作）的更多详情，可通过伍兹霍尔海岸与海洋科学中心野外活动网页查询：
