| Purpose | During Cruise M84/2 multibeam surveys were made using the vessel mounted echosounders. Since one aim of this cruise was related to hydroacoustic water column investigations. |
| Abstract | The deep sea KONGSBERG EM122 echosounder was used at all surveys during the whole cruise, meaning either designated bathymetry surveys or flare imaging-surveys. the maximum swath width used during this cruise was 110°. The multibeam system settings were optimized for the different purposes of bathymetric mapping and flare imaging. Data of the water column and the seafloor were recorded in one *.all file. |
