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 a Kongsberg EM122 during the transit from Montevideo (Uruguay) to Las Palmas (Canary Islands, Spain) in the Southern Atlantic Ocean. The deep-water MBES EM122 operates with an acoustic frequency of 12 kHz and a beam opening angle of 2° x 2° and up to 432 beams. The raw and unprocessed bathymetric and backscatter data is stored in Kongsberg format (*.all), each containing up to 30 min of data. The therein included 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 ...
