Purpose
Abstract The onboard R/V MARIA S. MERIAN bathymetric swath system comprises of followingelements: Multibeam Echosounder: Kongsberg Simrad EM-120 12 kHz Beamsteering sound velocity probe: AML SV Probe (not functional) Motion compensation: Kongsberg Seatex SeaPath 200 Heading/gyro sensor: Kongsberg Seatex SeaPath 200 Positioning: Primary antenna of Kongsberg Seatex SeaPath 200 Sound velocity profiles were provided by the CTD casts carried out by the participating oceanographer. During this cruise the swath coverage sector was reduced to 60 degrees on either side during normal sea conditions and to 50 degrees on either side in sea states higher than 4. The beam spacing is normally equidistant with equiangular available (not used on this cruise).
