PurposeResearch
Objectives1. To undertake grab surveys at a proposed artificial reef site off Lismore and at proposed dredged material disposal sites off Islay, to collect seabed sediment samples for physical and chemical analyses at the FRS Marine Laboratory, Aberdeen (FRS ML).
2. To undertake underwater television surveys at the proposed artificial reef site off Lismore and at the proposed dredged material disposal sites off Islay, to identify the predominant benthic epifauna species.
3. To undertake grab surveys at selected dredged material disposal sites in the Sea of Hebrides and the Minch, to collect seabed sediment samples for physical and chemical analyses at FRS ML.
4. To undertake an underwater television survey in the designated mooring area adjacent to the proposed Kishorn Decommissioning and Supply Base, to confirm the levels of surface debris and to identify the predominant benthic epifauna species (to supplement surveys undertaken during FRV Clupea Cruise 0100C).
5. To undertake grab surveys at two fish procesing waste disposal sites off the Orkney Isles, to collect seabed sediment samples for physical and chemical analyses at FRS ML. Where appropriate, core samples may be collected to supplement the grab samples, and Eh/pH analyses undertaken on FRV Clupea.
6. To undertake underwater television surveys at the Orkney Isles fish processing waste disposal sites, to identify the predominant benthic epifauna species and to confirm whether there is any evidence of an accumulation of shellfish processing waste.
7. To undertake Agassiz trawl surveys at the Orkney Isles fish processing waste disposal sites, to supplement the Agassiz trawl surveys and, if possible, to collect representative species for chemical analysis at FRS ML.
8. To undertake grab surveys at selected dredged material disposal sites around the Orkney Isles, Fair Isle and the Shetland Isles, to collect seabed sediment samples for physical and chemical analyses at FRS ML.
9. To undertake underwater television surveys at selected dredged material disposal sites around the Orkney Isles, Fair Isle and the Shetland Isles, to identify the predominant benthic epifauna species and to confirm the levels of man-made debris.
10. To undertake grab surveys at selected dredged material disposal sites off the north coast of Scotland, and in the Moray and Cromarty Firths, to collect seabed sediment samples for physical and chemical analyses at FRS ML.
11. To undertake underwater television surveys at selected dredged material disposal sites off the north coast of Scotland, and in the Moray and Cromarty Firths, to identify the predominant benthic epifauna species and to confirm the levels of man-made debris. Where appropriate, Agassiz trawls may be undertaken to supplement the underwater television surveys.
