1007S HERAS North sea herring acoustic survey-Scotia cruise 1007S dataset https://portal.medin.org.uk/portal/start.php?tpc=012_Marine_Scotland_FishDAC_1726 Daily folders (19) of Simrad format (.raw) acoustic data. 15 daily folders of acoustic data (.ek5 format) from autonomous echo-sounder. 19 Echoview format (EV) format analysis files. Excel biological data for 38 pelagic hauls. CTD data for 45 oblique deployments. NO Excel data for 45 plankton dips. 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 58º15-61.45’N and 4ºW to 2ºE, excluding Faroese waters. • To obtain biological samples for echo-sounder trace identification using a pelagic trawl. • To obtain samples of herring for biological analysis, including age, length, weight, sex, maturity, ichthyophonus infection and fat content. • To obtain hydrographic data for comparison with the horizontal and vertical distribution of herring. • To obtain plankton samples map the distribution and abundance of zooplankton. • To obtain in-situ target strength data on herring using the autonomous echo-sounder mounted in a drop frame. • To obtain live herring and live juvenile haddock for transport back to the laboratory. 20160407
