Swath sonar bathymetry data used for that dataset was recorded during RV METEOR cruises M79/2 (26.8.-21.9. 2009) using Kongsberg EM 120 multibeam echosounder and M113/1 (29.12.2014-22.1.2015) and M128 (2.-27.7.2016) using Kongsberg EM 122 multibeam echosounder. The water depth ranges from 14 to 4974 m. The data set stretches W-E from -29.9396°W to -22.9648°W and N-S from 39.3084°N to 36.5185°N. To enhance MBES data accuracy, several sound velocity profile casts were conducted in the vicinity of the working area prior and during the surveys. Raw data were converted to MB-System format. Data were manually edited for false measurements. No further artificial sound velocity profiles were used during further processing. A raster was calculated and stored in GeoTIFF format with a 50m resolution. In addition, the full resolution of available ASCII data and used for grid calculation are also archived in this dataset. To obtain a continuous grid, we recommend combining it with EMODNet data.
