Objectives1) To service three hydrographic monitoring moorings, one near the Stonehaven transect, and two in the Wee Bankie/Marr Bank study area.
2) To investigate the density distribution of sandeels buried in the sediment by carrying out a nocturnal stratified random Day grab survey across the Wee Bankie/Marr Bank study area. All sandeels caught will be measured, weighed and have their otoliths collected for age assessment.
3) To investigate variation in sandeel population age structure at different locations on the Wee Bankie and Marr Bank from samples collected using the Sandeel dredge.
4) To carry out a demersal trawl survey to determine the abundance and distribution of whiting, haddock and cod, the main fish predators of sandeels. At each trawl station the length frequency of all fish species caught will be determined. Sub-samples of the three gadoids will be weighed to determine length-weight relationships. Otoliths will be taken to determine age composition. Stomach samples will be collected to establish diet and food consumption rates, and livers and gonads will be removed to determine Hepato- and Gonado- Somatic Indices. (Any sandeels and clupeid fish caught during the demersal trawling will be worked up to determine length frequency distributions, length-weight relationships and age composition).
5) 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. The dual Bongo net may be deployed with the CTD to collect Zoo- and Phyto-plankton samples.
6) To undertake an acoustic survey of sandeels and clupeid fish in the water column using 38 and 120 kH. 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.
7) During the acoustic survey, Expendible Bathy-thermographs (XBTs) will be deployed to determine more precisely the locations of the boundaries between mixed and stratified water.
8) To conduct a RoxAnn survey of the substrate in the study area to investigate variation in the sandbank structure between this and previous cruises.
9) To conduct a survey of seabirds using the study area, to determine their abundance and distribution, using standard census methods.
10) To record all sightings of marine mammals (number of animals, species if possible, and their location) observed during the course of the cruise.
11) To conduct a hydrographic survey along a transect offshore of Stonehaven. At pre-selected locations the Seabird CTD sampler and the dual Bongo net will be deployed using a vertical dip. Water samples will be collected for salinity, nutrient and phytoplankton analysis. The 1 m plankton net will be deployed using a double oblique tow between selected stations along the transect.
