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

DOI

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.

These data should not be used for navigational purposes.
