PurposeResearch
Objectives1. To undertake a drop frame television survey of the Fraserburgh dredged material disposal site to assess the condition of the seabed, identify the predominant benthic epifauna species, and the distribution of man-made debris.
2. To undertake Agassiz, craib/gravity corer, grab and underwater television (UWT) surveys of the Peterhead or MacDuff and Aberdeen dredged material disposal sites. Samples will be returned to Aberdeen by 26 May.
3. To undertake grab surveys to collect seabed sediment samples from the Bell Rock and St. Abb's Head sewage sludge disposal sites, and from areas adjacent to both sites, for microbiological analysis on FRV Clupea, and for physical, chemical and biological analyses in the Marine Laboratory, Aberdeen (MLA). Where appropriate, core samples will be collected to supplement the grab samples, and Eh/pH analyses undertaken on FRV Clupea.
4. To undertake Agassiz trawl surveys to collect benthic epifauna samples from the areas outlined above, for biological analysis, and possible chemical analysis, in MLA.
5. To undertake underwater television surveys to investigate the benthic epifauna in the areas outlined above, for identification and enumeration of the predominant species in MLA.
6. To undertake grab surveys at selected dredged material disposal sites in the Firth of Forth to collect seabed sediment samples for physical and chemical analyses at ML.
7. To undertake underwater television surveys at selected dredged material disposal sites in the Firth of Forth, to confirm the levels of man-made debris and to identify the predominant benthic epifauna species.
8. To map the seabed bathymetry and sediment types on the sewage sludge disposal, dredged material and potential shellfish disposal sites, using RoxAnn.
9. To undertake a transmissometer survey and collect water samples in the Middle Bank and Blae Rock areas, to investigate the levels of turbidity in the water column.
10. To undertake grab and craib corer surveys at potential shellfish waste disposal sites off Eyemouth to collect seabed sediment samples for physical and chemical analyses at ML.
11. To undertake underwater television at potential shellfish waste disposal sites off Eyemouth, to confirm the levels of man-made debris and to identify the predominant benthic epifauna species.
