Multibeam bathymetry raw data was recorded in the North Pacific during cruise SO96/1 that took place between 1994-06-09 and 1994-06-27. The data was collected using the ship's own Atlas Hydrosweep DS echo sounder. ** For all details see the full metadata description at "https://doi.pangaea.de/10.1594/PANGAEA.944661"! ** File extension .dux was added to the file names during data curation. This file extension is necessary for data processing. These data should not be used for navigational purposes.
