Multibeam bathymetry processed data (Kongsberg EM 2040 working area dataset) of RV ALKOR during cruise AL628, west of Little Belt, Baltic Sea@en

Multibeam bathymetry processed data (EM 2040 multibeam echosounder) of RV ALKOR during cruise AL628 in the Baltic Sea. The raw data (.kmall) were processed using QPS Qimera software (v 2.6), based on the following workflow: 0.Raw data > 1.Apply correct Sound Velocity Profiles -> 2.Create dynamic surface (shallow Mode) -> 3.Apply Spline Filter (Medium/Strong) > 4. Finalize with manual 2D and 3D editing, -> 5.Export in GeoTIFF format and projected in the UTM32N coordinate system (EPSG:32632). The produced rasters are named AL628_EM2040_'working area'_'resolution in cm'. The bathymetry dataset here is gridded at 0.25 m and 0.50 m resolution. The data products were created in the context of the DAM (German Marine Research Alliance), CONMAR research project.波罗的海AL628航次期间，阿尔科号科考船（RV ALKOR）搭载EM 2040多波束测深仪（EM 2040 multibeam echosounder）获取的多波束水深处理数据。原始数据格式为.kmall，采用QPS Qimera软件（版本2.6）按照下述流程完成处理：0. 原始数据 → 1. 应用合规声速剖面 → 2. 创建动态海面（浅海模式） → 3. 应用样条滤波（中等/强滤波等级） → 4. 通过手动二维与三维编辑完成数据收尾 → 5. 导出为GeoTIFF格式，并投影至UTM32N坐标系（EPSG:32632）。生成的栅格数据命名规则为AL628_EM2040_‘作业区域’_‘分辨率（单位：厘米）’。本次提供的水深数据集网格分辨率为0.25米与0.50米。本数据集产品依托德国海洋研究联盟（DAM，German Marine Research Alliance）与CONMAR科研项目开发制作。
