Summary

Daily folders (17) of Simrad format (.raw) acoustic data. 17 Echoview format (EV) format analysis files. FSS format biological data for 33 pelagic hauls. CTD data for 32 vertical dips. Continual Thermosalinograph data. Continual AGDS data. continual hydrophone recordings for Cetaceans. 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 58º30’-62ºN and from 4ºW to 2ºE.To obtain biological samples for echosounder trace identification using a pelagic trawl.To test feasibility of using GoPro cameras mounted in the net and on a dropframe to further aid in species identification in the echogram scrutiny process.To obtain samples of herring for biological analysis, including age, length, weight, sex, maturity and ichthyophonus infection.To obtain hydrographic data for comparison with the horizontal and vertical distribution of herring. To obtain acoustic recordings of cetaceans during the survey using a towed hydrophone system.
