Summary of measurements |
- -Systematic echo integration from the coast to the open sea (speed = 8 knots) and spaced 12 miles out) with MOVIE and 38 and 120 kHz SIMRAD EK500 and 12 and 200 kHz OSSIAN.
-Trawl hauls to identify echoes (27, 5 of which done with 4FF). - Biometry of pelagic species. -Bathymetric (T, S) profiles done at the end of each trawl haul (23 CTD casts). -Continuous T (Temperature) and S (Salinity) recorded at subsurface (1,274MN). -Continuous recording of echograms sent by sounders 38, 120, 12 et 200 kHz (1745 MN). -Anchovy and sardine samples taken (1100 samples for otolith collection, taken in 16 hauls). -Anchovy and sardine samples taken (1700 samples collected for genetic studies by EPHE Perpignan). -Hake (191) samples to collect otoliths and stomach contents.
