Summary of measurements

-Systematic echo-integration (done at 8 knots on video legs perpendicular to the coast and 12 NM apart) using MOVIES+ with a SIMRAD EK500 38 kHz echosounder.
-Trawl hauls to identify echoes (23 performed, 10 of which using the 4FF).
-Biometry of pelagic species.
-Bathymetric (T, S per thousand) profiles done at the end of each trawl haul (16 CTD).
-Continuous T (Temperature) and S per thousand (Salinity) recorded at subsurface (1,700 NM).
-Continuous recording of demersal echograms sent by 38, 49, and 12 kHz sounders (1,621 NM).
-Anchovy maturity stages (2,234 samples made in 17 trawl hauls).
