2004 Strategic Environmental Assessment SEA5 Sediment hydrocarbon analysis of seabed sediments collected in North of Scotland, August - October 2003
As part of the UK Department of Trade and Industry's (now Department of Energy and Climate Change) ongoing sectorial Strategic Environmental Assessment a seabed survey programme (SEA5) was undertaken between August and early October 2003 for the UKCS areas lying between Scotland and Orkney and Shetland. This report summarises the sediment total hydrocarbon and aromatic data generated from the analyses of selected samples from the study areas detailed: Fair Isle - 46 to 198m water depth; Outer Moray Firth A - 61 to 171m; Outer Moray Firth B - 57 to 100m; Sandy Riddle - 30 to 70m; Smith Bank - 39m; Southern Trench - 76 to 252m.

- The Strategic Environmental Assessment (SEA) data portal provides free access to available data and reports which have been produced through the UK Department of Energy and Climate Change SEA process. The site is run and managed by BGS on behalf of the Department of Energy and Climate Change (DECC). Many files can be downloaded directly from this website. Those that are too large to download can be ordered via the website for postal delivery from BGS.

Data Quality
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).
