  <dc:description xmlns:dc="http://purl.org/dc/elements/1.1/">Daily folders (18) of Simrad format (.raw) acoustic data. 18 Echoview format (EV) format analysis files. Excel biological data for 28 pelagic hauls. 31 deployments of OCEAN sampler for plankton and CTD sampling. 21 camera stations. 56 sediment grab samples. Continual Thermosalinograph data. Continual AGDS data.
Objectives: To conduct an acoustic survey to estimate the abundance and distribution of herring in the north western North Sea and north of Scotland between 58&#xBA;30&#x2019;-62&#xBA;N and 4&#xBA;W to 2&#xBA;E, excluding Faroese waters.To obtain biological samples for echosounder trace identification using a pelagic trawl.	To obtain samples of herring for biological analysis, including age, length, weight, sex, maturity, fat content and ichthyophonus infection.To obtain hydrographic data for comparison with the horizontal and vertical distribution of herring.To obtain plankton samples to map the distribution and abundance of zooplankton.To obtain information on seabed habitats using grab sampling and drop frame TV.</dc:description>
