Multibeam bathymetry processed data (Kongsberg EM 122 entire dataset) of RV SONNE during cruise SO261, Atacama Trench, South Pacific Ocean

Multibeam data were collected during RV Sonne cruise SO261 (2018-03-03 to 2018-04-02). Multibeam sonar system was Kongsberg EM 122 multibeam echosounder. Data are processed with Caris HIPS, including sound velocity correction with SV data from CTDs and World Ocean Atlas 18 (https://www.ncei.noaa.gov/archive/accession/NCEI-WOA18), tidal correction with TPXO9_atlas_v5 (https://www.tpxo.net/global/tpxo9-atlas), 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.
