| dc.description.abstract | Ecosystem cruise with abundance estimation and biological sampling of Northeast Atlantic (NEA) mackerel, Norwegian spring-spawning (NSS) herring and North Sea herring. Predetermined station net for systematic biological sampling with the standardized Multpelt 832 pelagic sampling trawl with acoustic position sensors (SIMRAD) and video capture. Oceanographical measurements with ADCP (Teledyne RDI) and CTD (SAIV and SeaBird) cast 0-500 m depth. Zooplankton sampling with WP2 vertical net hauls 0-200 m depth.
Acoustic mapping of pelagic fish and plankton with multi-frequency echo sounders (SIMRAD EK60:18kHz, 38kHz, 120kHz, 200kHz and 333kHz) and multibeam sonar
(SIMRAD SX), Opportunistic marine mammal observations. Total survey length: 4395 nmi | |
