Abstract:

Hydroacoustic raw data from the M153 cruise aboard the RV Meteor in 2019 (15/02/2019 to 27/03/2019) to the Benguela Upwelling System. The hydroacoustics were used to observe the distribution of krill, zooplankton and pelagic fish up to the mesopelagic zone for the project TRAFFIC. We used a SIMRAD EK80 system with a transportable SIMRAD WBT Mini and combined transducer with 38 and 200 kHz. Data deeper than 750m has been identified as range limit and excluded.
