Status | Completed |
Port of departure | Fraserburgh, United Kingdom |
Port of return | Fraserburgh, United Kingdom |
Purpose | Research |
Objectives | To carry out an echo-integrator survey to determine the biomass and distribution of pelagic fish in the Moray Firth and to determine fish species and size composition through trawl sampling. To assess the abundance and distribution of predatory fish by demersal trawl sampling and to collect stomach samples for dietary and food consumption analysis. To determine the numbers and distribution of mammalian and avian predators using transect census methods and to collect observation data regarding diet. To determine spatial variation in water temperature and salinity depth profiles using CTD recorders and reverser bottle sampling. To determine the abundance distribution of phytoplankton and zooplankton using reverser bottle and GULF III sampling. To map seabed sediment type using ROXANN and grab sampling. |
