Statement

This report was compiled by Harwell Scientifics under contract to Geotek Ltd as part of the UK Department of Energy and Climate Change's Offshore Energy Strategic Environmental Assessment programme. Sediment samples were collected between August and early October 2003. Sediments were extracted by ultrasonification and the extracts cleaned up using column chromatography. The resulting extracts were analysed for n-alkane content (nC12-nC36) using gas chromatography with flame ionisation detection, and for selected PAH content using gas chromatography/mass spectrometry. The concentrations of n-alkanes was determined by measuring the response of each component (nC12-nC36) against a series of internal standards and summed to give a total n-alkane value for each sediment sample. A total figure was also calculated for the UCM (unresolved complex material).
