Abstract | During cruise MSM 30, system settings below were used for EM122 multibeam surveys: - (Runtime Parameters - Sounder Main) - Max. angle: 2*65° - Max coverage: depending on water depth, usually higher than angular limit - Angular coverage mode: AUTO (MANUAL results in less beams being used) - Beam spacing: EQDIST - Ping mode: AUTO - Pitch stabilization: On - Heading filter: MEDIUM Additional to the bathymetry water columne data was recorded. The water columne was stored as wcd-files. During cruise MSM30, sound velocity and temperature profiles were measured at nine locations whenever the water depths were changing noticeably. |
