ObjectivesObjectives

1. To undertake an acoustic survey of sandeels and clupeid fish in the water column using 38 and 120 kHz. Concentrations of fish will be sampled using the pelagic trawl. Species composition and length frequency distributions of fish caught will be determined. Sub samples will be weighed and their otoliths removed to establish length-weight relationships and age composition. Stomach samples will be collected for diet analysis

2. To conduct a RoxAnn survey of the substrate in the study area to investigate variation in the sandbank structure between this and previous cruises.

3. To conduct a survey of seabirds using the study area, to determine their abundance and distribution, using standard census methods.

4. To record all sightings of marine mammals (number of animals, species if possible, and their location) observed during the course of the cruise.

5. To carry out a demersal trawl survey to determine the abundance and distribution of piscivorous fish predators in the area. At each trawl station, the length frequency of all fish species caught will be determined. Sub-samples of cod, haddock, whiting, Norway pout, poor cod, common dab, long rough dab and grey gurnards will be weighed to determine length-weight relationships and stomach samples collected for diet and food consumption rate analysis.

6. To determine spatial variation in water temperature and salinity across the Wee Bankie/Marr Bank study area using a Seabird CTD sampler. Approximately 40 vertical dip stations will be sampled utilising the demersal trawl stations and additional locations mid-way between the trawl stations.

7. To undertake plankton sampling to determine spatial variation in the abundance of the potential prey of sandeels, herring and sprat.

Procedure

Scientific equipment will be loaded onto Alba na Mara on 28 May. Scientists will join the vessel by 1000 hours on the morning of Wednesday 2 June and the Alba na Mara will sail shortly thereafter, makin
