Objectives1) To undertake a grab survey in the vicinity of the former sewage sludge disposal sites off Garroch Head, to collect seabed sediment samples for microbiological analyses on FRV Clupea and physical and chemical analyses at the FRS Marine Laboratory, Aberdeen.
2) To undertake a Craib corer survey in the vicinity of the former sewage sludge disposal sites off Garroch Head, to collect seabed sediment samples for Eh/pH analyses on FRV Clupea.
3) To undertake an Agassiz trawl survey in the vicinity of the former sewage sludge disposal sites off Garroch Head to identify the predominant benthic epifauna species and, if possible, to collect representative species for chemical analysis at FRS ML.
4) To undertake an underwater television survey in the vicinity of the former sewage sludge disposal sites off Garroch Head, to assess the distribution of man-made debris and to supplement the Agassiz trawl surveys.
5) To undertake beam trawl surveys at selected locations in the Firth of Clyde, to collect Buccinum and Neptunia spp. For TBT and DBT analyses at FRS ML.
6) To undertake grab surveys at selected dredged material disposal sites in the Firth of Clyde, the North Channel, the Sea of Hebrides and the Minch, to collect seabed sediment samples for physical and chemical analyses at FRS ML.
7) To undertake underwater television surveys at selected dredged material disposal sites in the Firth of Clyde, the North Channel, the Sea of Hebrides and the Minch, to confirm the levels of man-made debris and to identify the predominant benthic epifauna species.
8) To undertake grab surveys at selected dredged material disposal sites around the Shetland Isles and Fair Isle, 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 Shetland Isles and Fair Isle, to confirm the levels of man-made debris and to identify the predominant benthic epifauna species.
10) To undertake underwater television surveys at the Helmsdale and Fraserburgh dredged material disposal sites, to confirm the levels of surface debris and to identify the predominant benthic epifauna species.
