EK80 raw multi-frequency (18, 38, 70, 120, 200 kHz) acoustic data collected during RV Sarmiento de Gamboa cruise 'Sustainable Management of Mesopelagic Resources' (SUMMER) in 2020 to the Mediterranean


EK80 raw data were collected during the 2020 SUMMER (Sustainable Management of Mesopelagic Resources) Mediterranean cruise (30 September 2020 to 18 October 2020) carried out by RV Sarmiento de Gamboa. Five frequencies (18, 38, 70, 120, 200 kHz) were operated on continuous wave (CW) mode with specific settings by the hull-mounted EK80. A maximum volume of 100 MB of individual raw file was used. The recording depths for 5 frequencies from 18 to 200 kHz were 1000, 1000, 750, 500, and 200 m. The transmitted power for 5 frequencies from 18 to 200 kHz were set to 2000, 1000, 750, 250 and 150 W. Calibrations were carried out on the 1st of October 2020 using a 33 mm tungsten sphere, and the calibration results were applied to the EK80. Raw power (W), number of transducer segments and transceiver impedance (Ohm) were stored in raw proprietary Simrad format (.raw, .idx). The raw files were all recorded according to the UTC+00:00 time zone.
