SUBSAINTES AUV AsterX Bathymetry and backscatter (1m resolution)

Near-bottom multibeam bathymetry acquired at the French Antilles volcanic arc between Les Saintes et Dominica islands. High-resolution bathymetry data (1 m/pixel) were acquired by the autonomous underwater vehicle (AUV) AsterX, deployed during the 2017 Subsaintes cruise (https://doi.org/10.17600/17001000. The dataset consists of dives #394 through #404, after renavigation of the veichile. This dataset includes both grids of individual dives (bathymetry and backscatter, in GRD format), and mosaics combining these dives in 3 larger grids (GEOTIFF). All grids are provided in WGS 84 projection.

本数据集为采集于莱斯桑特群岛与多米尼克岛之间的法属安的列斯火山弧区域的近海底多波束测深数据。本次高分辨率测深数据（分辨率为1米/像素）由自主水下航行器（AUV）AsterX采集，该设备部署于2017年Subsaintes航次期间（数据DOI：https://doi.org/10.17600/17001000）。本数据集涵盖经航行器航迹重导航处理后的第394至404号下潜任务数据，包含两类数据产品：一是单次下潜任务对应的测深与反向散射网格数据（格式为GRD）；二是将多批次下潜数据拼接而成的3幅大型拼接网格（格式为GEOTIFF）。所有网格数据均采用WGS 84坐标系投影。
