| Cruise identifier | 1105S | ||||||||
| Cruise period | 2005-08-16 — 2005-08-30 | ||||||||
| Status | Completed | ||||||||
| Port of departure | Aberdeen, United Kingdom | ||||||||
| Port of return | Aberdeen, United Kingdom | ||||||||
| Purpose | Research | ||||||||
| Objectives | 1. To undertake the Garroch Head post cessation survey in collaboration with Scottish Water. Survey will include: fishing, grabbing, water sampling, coring and underwater TV (UTV).
2. To undertake swathe bathymetric and ROV television surveys within the Minches, east of Mingulay. 3. To undertake a grabbing survey to investigate potential new NMMP sites in the vicinity of Shetland to give a greater coverage to enable assessments of the quality of the Scottish marine environment to be made. 4. To undertake standard check monitoring duties, seabed sampling and underwater television, at dredged material disposal sites in the Clyde, Shetland and Small Isles. 5. To undertake bathymetric surveys of selected dredged spoil disposal sites and the Lismore artificial reef, up to a maximum of eight sites on the route from Aberdeen to Garroch Head calling at: Aberdeen, Shetland, Garroch Head, Firth of Lorne and Cloch Point. To map the seabed and to ascertain the usefulness of this technique as a check monitoring tool for the future. 6. To identify potential new sea disposal sites off Shetland. Survey will include grabbing, small beam trawl (agassiz) and underwater TV (dropped from programme). 7. To collect flatfish from the Firth of Clyde for the measurement of DNA Damage; samples to be taken from scheduled trawls and analysis partly undertaken on board. 8. To collect field samples to assist in estimating the biochemical availability of organic contaminants in selected sediments containing apparently high concentrations of PAH, CBs, or PBDE's. Samples to be collected during other operations described above. 9. To collect swathe bathymetry and UTV data from the disused explosives ground in Aberdeen Bay. (Additional Work) 10. To collect seawater for radio-caesium analysis at five locations on route. | ||||||||
