Summary of measurements |
- -Systematic echointegration (done at 8 knots on legs from coast to offshore, perpendicular to the coast and 12 nm apart) using MOVIES+ and SIMRAD EK500-38 and 120 kHz and OSSIAN 12 and 200 kHz echosounders.
-Trawl hauls to identify echoes (33, 6 of which done with 4FF). -Biometry of pelagic species. -Bathymetric (T, S) profiles done at the end of each trawl haul (26 CTD). -Continuous T (Temperature) and S (Salinity) recorded at subsurface (NM). -Continuous recording of echograms sent by sounders 38, 120, 12 and 200 kHz (1,462 NM). -Anchovy and sardine samples taken (862 samples for otolith collection, taken in 15 hauls). -Hake (91) samples to collect otoliths and stomach contents.
