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.
