Abstract:
Swath sonar bathymetry data used for that dataset was recorded during RV SONNE during cruise SO286 using Kongsberg EM 122 multibeam echosounder. The cruise took place between 05.11.2021 - 08.12.2021 in the Atlanic Ocean. Data were recorded throughout the whole time spend outside EEZs. The approximate average depth of the entire dataset is around 4000m. To enhance MBES data accuracy, sound velocity profile casts were conducted in the vicinity of the working area prior to the survey using CTD rosette. During transits, sound velocity profile from the WOA13 were aplied via Sound Speed Manager Software. After processing, these data were directly imported into the MBES Acquisition software Kongsberg SIS Seafloor Information System. Data were manually edited for false measurements using Qimera. A raster was calculated and stored in GeoTIFF format with a 100m resolution (negative values), WGS84 as vertical datum and UTM as a projection. Data products include ungridded soundings, a bathymetric grid (100 m resolution) and an uncalibrated backscatter grid (200m resolution). The data processing and provision was accomplished within work package 2 of the EU Horizon 2020 project iAtlantic- Integrated Assessment of Atlantic Marine Ecosystem in Space and Time (https://www.iatlantic.eu/) IceAge project (https://www.iceage-project.org/).
