Multibeam bathymetry processed data (Kongsberg EM 122 working area dataset, Generic sensor format) of RV MARIA S. MERIAN during cruise MSM82/2, South Atlantic Ocean ...

The multibeam echo sounder (MBES) data was collected from the 28.04.2019 (23:19 UTC) to the 07.05.2019 (16:42 UTC) with the Kongsberg EM122 on RV Maria S. Merian during the transit from Montevideo (Uruguay) to Las Palmas (Canary Islands, Spain) in the Southern Atlantic Ocean (MSM82/2). The deep-wate...

Description
Summary:The multibeam echo sounder (MBES) data was collected from the 28.04.2019 (23:19 UTC) to the 07.05.2019 (16:42 UTC) with the Kongsberg EM122 on RV Maria S. Merian during the transit from Montevideo (Uruguay) to Las Palmas (Canary Islands, Spain) in the Southern Atlantic Ocean (MSM82/2). The deep-water MBES EM122 operates with an acoustic frequency of 12 kHz and a beam opening angle of 2° x 2°. The time, motion and position data (WGS84, geographic) was measured by the Kongsberg Seapath system on board. During the acquisition the echo sounder was monitored as well as settings and filter adjusted according to the environment. The swath opening angle was set between 65° and 70°. As the data was collected during transit, no specific survey was performed.Sound velocity profiles (SVP) were measured on the 01.05.2019 (XSV probe) and 04.05.2019 (with CTD) and applied in the MBES acquisition software SIS. To improve the bathymetric data before the first SVP measurement, an synthetic SVP extracted from the World Ocean ...
