/* DATA DESCRIPTION: Citation: Cornish, Natalie; Baumbusch, Clara; Dreutter, Simon; Dorschel, Boris (2026): Multibeam bathymetry processed data (Atlas Hydrosweep DS 3 echo sounder entire dataset) of RV POLARSTERN during cruise PS154/1, Atlantic Ocean [dataset]. PANGAEA, https://doi.pangaea.de/10.1594/PANGAEA.995440 (DOI registration in progress) Abstract: Multibeam data were collected during RV Polarstern cruise PS154/1 (2026-04-11 to 2026-04-30). 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 CTDs and World Ocean Atlas 23 (https://www.ncei.noaa.gov/archive/accession/NCEI-WOA23), 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 ( ). Additional 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.
