ObjectivesTo carry out an acoustic survey, backed up by pelagic trawling, to determine the biomass and distribution of pelagic fish in an area off the Firth of Froth which included the Wee Bankie and Marr Bank. To assess the abundance and distribution of seabirds in the area using standard transect census techniques and to locate the feeding sites of dye-marked kittiwakes breeding on the Isle of May. To record the location of all marine mammals observed at sea. To map seabed sediment type using the acoustic system RoxAnn and to collect sediment samples to "groundtruth" the RoxAnn data. To determine spatial variation in the water temperature and salinity profile within the study area. To carry out a bottom trawl survey to determine the abundance, distribution and length composition of piscivorous demersal fish species and to collect stomach samples from these fish to determine spatial variation in their diet. To determine weight-length relationships for each fish predator species, and examine spatial variation in fish condition. To carry out a night-time grab survey, over sediments previously determined as suitable sandeel habitat, to assess sandeel abundance and distribution. The sediment samples collected during this survey will also be used to assess the RoxAnn derived sandeel habitat map.
