EK80 raw broadband (18, 35 to 260 kHz) stationary observations during RV Sarmiento de Gamboa cruise 'Sustainable Management of Mesopelagic Resources' (SUMMER) in 2020 to the Mediterranean


EK80 raw broadband stationary observations were made during the 2020 SUMMER (Sustainable Management of Mesopelagic Resources) Mediterranean cruise (30 September 2020 to 18 October 2020) aboard the RV Sarmiento de Gamboa. A hull-mounted EK80 system (with nominal frequencies of 18, 38, 70, 120, 200 kHz) was operated on frequency modulated (FM) mode with specific settings. In total, 22 deployments were collected along with the wideband autonomous transceiver (WBAT) observations to maximise the frequency band range and compare to the WBAT data. A maximum volume of 100 MB per individual raw file was used. The recording depth for 5 frequencies was set to 500 m. The transmitted power for 5 frequencies from 18 to 200 kHz were set to 2000, 1000, 750, 250, 150 W according to the published papers. Raw power (W), number of transducer segments and transceiver impedance (Ohm) were stored in raw proprietary Simrad format (.raw). The raw files were all recorded according to the UTC+00:00 time zone. Data format and calibrations are the same as for the EK80 underway narrowband data.
