| Objectives | Objectives
1. To complete an internationally coordinated demersal trawling survey in the North Sea in ICES areas IVa and IVb. 2. In case of additional available survey time, to undertake experimental tows in water depths of 250 to 300 m or conduct tows around Shetland to increase resolution in perceived areas of high cod abundance. 3. To obtain temperature, salinity and dissolved oxygen concentration data from the water column at each trawling station using a RBR CTD. 4. To sample surface and bottom water for Nutrients, Chlorophyll and dissolved oxygen calibration samples from 34 stations (Lower freezer to be kept free of fish for samples). 5. On Part 1, undertake opportunistic MIK sampling for pre-metamorphosed clupeoid larvae during the hours of darkness within the trawl survey area. 6. To collect additional biological data in connection with the Data Collection Framework (DCF) and UK Work Plan. 7. To identify and quantify all gelatinous zooplankton caught during trawling. 8. To collect and quantify all marine litter encountered on the survey for MSFD. 9. To identify and quantify the presence of non-indigenous species observed. 10. To collect low nutrient sea water from for the MSS chemistry department. 11. To collect stomach samples from Whiting, Anglers and Megrim for an EU pilot into international stomach sampling on fisheries surveys. 12. To obtain data and frozen samples for pelagic fish (Herring, Mackerel and Blue Whiting) for weight loss analysis. 13. To collect a retained marine molluscs and gastropod shells for distribution mapping. 14. To obtain data and Whiting samples for an AFBI-NI study into genetic differences in populations between areas. 15. To collect and freeze juvenile Mackerel for an IMR Bergan study on the myxozoan parasite Kudoa thyrsites. |
