ObjectivesObjectives

1. To conduct an acoustic survey to estimate the abundance and distribution of herring in the northwestern North Sea and north of Scotland between 58º30'-62ºN and from the shelf edge to 2ºE, 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 and ichthyophonus infection.
4. To obtain hydrographic data for comparison with the horizontal and vertical distribution of herring.
5. To deploy Stonehaven hydrographic mooring.

Procedure

All gear will be loaded in Aberdeen on Monday 4 July. Access will be required to the drop keel area to allow removal of the Reson swathe transducer used on the previous cruise and installation of the multi sampler transducers. It is hoped that this can be done on 4 July. The vessel will depart Aberdeen on Wednesday 6 July and make passage for Stonehaven Bay to deploy the hydrographic mooring, after which two staff members will be disembarked and transported ashore by RHIB. The vessel will then head for Scapa Flow, Orkney Islands, where a calibration of all echosounders will take place (approximately 8 12 hours at anchor). Crew training and trial deployments of fishing gear will take place en route as convenient for the fishing master.

The survey will commence after calibration and follow a pattern of parallel transects running east/west, at normal steaming speed (approximately 10.5 knots), progressing northwards, along the east side of Orkney/Shetland, and southwards along the west side. The survey area is bounded by 58º30'-62ºN and 02ºE to the 250 m contour. This survey differs from previous ones in the series in that it will include an additional area previously surveyed by the West Coast charter. In order to cover the additional area, transect spacing has been increased to a minimum of 15 nm for the
