Multibeam bathymetry processed data (Atlas Hydrosweep DS 3 echo sounder entire dataset) of RV POLARSTERN during cruise PS128, Southern Ocean


Multibeam data were collected during RV Polarstern cruise PS128 (2022-01-06 to 2022-02-28). 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 and World Ocean Atlas 13 (, tidal correction with TPXO9_atlas_v5 (, and manual cleaning. The soundings are combined in daily files, the format is XYZ ASCII ( ). 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.

These data should not be used for navigational purposes.
