Purpose
Abstract The EM 710 KONGSBERG multibeam echosounder operates was switched on only at shallower areas, with depths up to max. 1200 m. The swath coverage during bathymetric surveys was kept around 110-130°.The swath width for bathymetric mapping was 90° due to insufficient data quality of the outer beams at wider opening angles. The swath was regularly reduced to 70° for water column flare mapping. Data of the water column and the seafloor were recorded in one *.all file.
