Cruise Inventory Information
| Long name | FRV Clupea (74CU) cruise 1798C |
|---|---|
| Short name | 1798C |
| Objectives and Narrative | To carry out a night time grab survey, over sediments previously determined as suitable sandeel habitat, to assess sandeel abundance and distribution. Length and age frequency distribution data were collected. The sediment samples collected during this survey will also be used to assess the RoxAnn derived sandeel habitat map. To 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 Forth which included the Wee Bankie and Marr Bank. Again data to examine age and length frequency distribution of pelagic fish were collected. To assess the abundance and distribution of seabirds in the area using standard transect census techniques and to locate the feeding site of de-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. |
