Near-bottom bathymetry and back-scatter data acquired with AUV IDEFX during the AMORGOS-22 cruise

near-bottom multibeam bathymetry and back-scatter data acquired along the amorgos and santorini-amorgos faults, in the aegean sea. high-resolution bathymetry data (1 m/pixel) were acquired by the autonomous underwater vehicle (auv) idefx, deployed during the amorgos-22 cruise (https://doi.org/10.17600/18001479) with the mbes em2040. the dataset consists of six dems as well as fourteen back-scatter mosaics (i.e. two versions for each dives, raw and processed (compention of the antenna diagram)). in addition, a dem extracted from dive 2 is provided. the bathymetric data were processed with globe, while the back-scatter data were processed with sonarscope. renavigation of the vehicule was necessary during processing and is applied to both the bathymetric grids and backscatter mosaics. files are provided in tif format, projected in utm 35 n (wgs 84).

在海滨地区，沿爱琴海的阿摩戈斯断层和桑托里尼-阿摩戈斯断层采集了近底多波束测深和回波散射数据。通过在阿摩戈斯-22巡航期间（https://doi.org/10.17600/18001479）部署的自主水下航行器（AUV）iDEFX，利用MBES EM2040获取了高分辨率测深数据（1米/像素）。该数据集包括六个数字高程模型（DEM）以及十四个回波散射镶嵌图（即每个潜水作业的两种版本，原始和经过处理（天线图案的对比度））。此外，还提供了一个从潜水2提取的DEM。测深数据使用Globe进行处理，而回波散射数据使用SonarScope进行处理。在处理过程中，需要对航行器进行重导航，并应用于测深网格和回波散射镶嵌图。文件以tif格式提供，投影在UTM 35 N（WGS 84）上。
