  <dc:description xmlns:dc="http://purl.org/dc/elements/1.1/">Daily folders (22) of Simrad format (.ek5) acoustic data. 22 Echoview format (EV) format analysis files. Excel biological data for 40 pelagic hauls. CTD data for 18 vertical dips. SVP data for 18 deployments. Data for 40 minilogger deployments. Continual Thermosalinograph data. Continual AGDS data.
Objectives:
1.	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&#xB0;15-61.45'N and 4&#xB0;W to 2&#xB0;E, excluding Faroese waters.
2.	To obtain echosounder trace identification using pelagic trawl.
3.	To obtain samples of herring for biological analysis, including age, length, weight, sex, maturity and ichthyophonus infection.
4.	To obtain photographic records for fish maturity analysis.
5.	To obtain hydrographic data for comparison with the horizontal and vertical distribution of herring.
6.	To obtain plankton samples for acoustic identification work.
7.	To obtain plankton data using Utow.
8.	To conduct SAT (Sea Acceptance Trial) on new EK60 echo sounder system.</dc:description>
