Multibeam echosounder model SeaBat 7125 SV2
The r/v Oceanograf is equipped with a SeaBat 7125 multibeam echosounder (MBES) by Teledyne Reson. It can operate at two frequencies 200 and 400 kHz. The angular width of the transmitted beam for both frequencies, is 140°. The angular resolution of a single beam is 0.54°±0.03° x 1.1°±0.2° across and along the profile for 400 kHz and 1.1°±0.05° x 2.2°±0.5° for 200 kHz respectively. The maximum ping frequency reaches 50 Hz for both operating frequencies.
