| Abstract | During the P336 cruise, the ELAC SEABEAM 1050 multibeam echosounder was used for a continuous mapping of the seafloor. The SEABEAM 1050 uses a frequency of about 12 KHz with a whole angular coverage sector of up to 150° (75° per port-/starboard-side). One ping is sent and the receiving signal is formed into 191 beams by the transducer unit through the hydrophones in the receiver unit. The beam spacing can be defined as equidistant or equiangular, or a mix of both. Running the system in full 150°-configuration the system maps a swath of roughly 4-5 times the water depth. The ping-rate depends on the water depth and the runtime of the signal through the water column. Depending on the state of the sea, an opening angle of 60-70° was used, restricting the coverage to a max.14 km wide swath to gain a more continuous spacing of beams on the ocean floor. The spacing within these limits was controlled automatically by the echosounder system. |
