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 58.15-61.45 N and 4 W to 2 E, excluding Faroese waters.

2. To obtain biological samples for echosounder trace identification using a pelagic trawl.

3. To obtain samples of herring for biological analysis, including age, length, weight, sex, maturity, ichthyophonus infection and fat content.

4. To obtain hydrographic data for comparison with the horizontal and vertical distribution of herring.

5. To obtain plankton samples map the distribution and abundance of zooplankton.

6. To obtain in-situ target strength data on herring using the autonomous echosounder mounted in a drop frame.

7. To obtain live herring and live juvenile haddock for transport back to the laboratory.


A half landing took place on 9 July in Lerwick in accordance with rest provision for the Working Time Directive and for the exchange of personnel, (P Fernandes and Jane Mills left and Dave Reid and Owen Goudie joined). The vessel resumed surveying at 1100 on 10 July. West of the Shetland Isles, transects extended from the coast to the shelf edge or longitude 4 W. The survey was completed on 17 July at around 1800. Three of the four transducers were calibrated successfully in Scapa Flow between 2100 on 17 July and 1500 on 18 July. The vessel returned to Aberdeen on the morning of 19 July.
