PurposeResearch
Objectives1. To deploy caged mussels and absorbent traps on moorings in the vicinity of two offshore oil installations.
2. To sample fish and shellfish by trawl along gradients from known discharge points for sensory assessment and tissue PAH determination.
3. To sample fish by trawl along gradients from known discharge points for biomarker determinations and organ-specific histopathological analyses.
4. To sample sediments, in the same areas as the trawls are taken, for hydrocarbon concentrations.
5. To sample nephrops from the Burra Haaf, and a reference site, in relation to the on-going Braer monitoring programme.
6. To sample fish and shellfish by trawl on the western shelf to extend our knowledge of the distribution of petrogenic hydrocarbons in biota and sediments in this area.
7. To collect and maintain live samples of fish and shellfish for processing by NCIMB.
8. To facilitate the production of video and still photography describing the use of scientific sampling equipment and subsequent processing of samples aboard Scotia.
