PurposeResearch
Objectives1. To undertake grab surveys at the Beatrice C platform, the Marcel and Bravo oilfield prospects, three single-well drilling sites and a control area located 20 kilometres to the southeast of the Beatrice C platform, to collect seabed sediment samples for physical and chemical analyses in the Marine Laboratory, Aberdeen (MLA).
2. To undertake trawl surveys at the Beatrice C platform, the Marcel and Bravo oilfield prospects, three single-well drilling sites and the Moray Firth control site, to collect samples of representative species for chemical analyses at MLA.
3. To undertake a grab survey of the Guillam Bank industrial waste disposal site, to collect seabed sediment samples for physical and chemical analyses at MLA. Where appropriate, core samples may be collected for Eh/pH analyses on FRV Clupea.
4. To undertake an underwater television survey at the Guillam Bank industrial waste disposal site, to confirm the levels of seabed debris and to identify the predominant benthic epifauna species.
5. To undertake Agassiz and beam trawl surveys at the Guillam Bank industrial waste disposal site, to collect samples of representative species for chemical analysis at MLA.
6. To undertake grab surveys at selected dredged material disposal sites around the Shetland Isles, Fair Isle and Orkney Isles, to collect seabed sediment samples for physical and chemical analyses at MLA.
7. To undertake underwater television surveys at selected dredged material disposal sites around the Shetland Isles, Fair Isle and Orkney Isles, to confirm the levels of seabed debris and to identify the predominant benthic epifauna species.
8. To undertake a grab survey at the Stromness fish processing waste disposal site to collect seabed sediment samples for physical and chemical analyses at MLA. Where appropriate, core samples may be collected for Eh/pH analyses on FRV Clupea. Cancelled due to time lost to bad weather.
9. To undertake an underwater television survey at the Stromness fish processing waste disposal site, to confirm whether there is evidence of accumulation of waste materials on the sea bed and to identify the predominant benthic epifauna species. Cancelled due to time lost to bad weather.
10. To undertake grab surveys at selected dredged material disposal sites off the north coast of Scotland, and in the Moray, Cromarty, Inverness and Beauly Firths, to collect seabed sediment samples for physical and chemical analyses at MLA.
11. To undertake additional grab surveys at the Sutors and Inverness (Beauly Basin) dredged material disposal sites, to collect seabed sediment samples for biological analyses. Where appropriate, core samples may be collected for Eh/pH analyses on FRV Clupea.
12. To undertake underwater television surveys at selected dredged material disposal sites off the north coast of Scotland, and in the Moray, Cromarty, Inverness and Beauly Firths, to confirm the levels of seabed debris and to identify the predominant epifauna species.
13. To undertake Agassiz trawl surveys at the Sutors and Beauly Basing dredged material disposal sites, to identify the predominant benthic epifauna species. Where appropriate, samples of representative species may be retained for chemical analysis at MLA.
