Multibeam bathymetry processed data (Atlas Hydrosweep DS 3 echo sounder entire dataset) of RV POLARSTERN during cruise PS127, Atlantic Ocean

Multibeam data were collected during RV Polarstern cruise PS127 (2021-12-04 to 2022-01-02). Multibeam sonar system was Atlas Hydrographic Hydrosweep DS 3 multibeam echo sounder. Data are processed with Caris HIPS, including sound velocity correction with SV data from SVPs, CTDs, UCTDs and World Ocean Atlas 13 (https://doi.org/10.7289/v5f769gt), tidal correction with TPXO9_atlas_v5 (https://www.tpxo.net), and manual cleaning. The soundings are combined in daily files, the format is XYZ ASCII (<Lon> <Lat> <Depth in meters, positive up, relative to mean sea level>). Additional blockmedian grids have been computed with depth dependent cell size to visualize the data. These grids are not meant for scientific analysis or navigation, but for overview purposes only.

Multibeam bathymetry processed data (NORBIT iWBMS entire dataset) from 2021, Laacher See, Germany

This dataset contains a processed bathymetric data of the volcanic crater lake Laacher See in Germany recorded on 13-14 September 2021, acquired for the purpose of describing the lake sedimentary infill and volcanic degassing processes occurring in the crater. It has a coverage of 2.81 km², which corresponds to ca. 84% of the total lake surface area. The nearshore zone was not mapped due to vegetation growth limiting the data quality. Depths are expressed in meters below lake level, ranging from 2.4 m to 50.5 m. The bathymetric data was acquired using a Norbit WBMSe Wideband Multibeam Sonar from the Flanders Marine Institute (Vlaams Instituut voor de Zee, VLIZ) and the system was operated at a source frequency of 400 kHz with a maximum swath angle of 150°, transmitting 512 beams with a beam width of 0.9° x 1.9°. Sound velocity profiles were collected throughout the survey to account for temporal variations in water-column sound velocity. Processing of the raw data was done using Qimera 2.5.1 (QPS) and included correction for pitch, roll and heading offsets during acquisition, and manual removal of artefacts such as gas bubbles, vegetation and inconsistent soundings in overlapping swaths. From the processed data, a bathymetric grid with a ~1m cell size was constructed.
