2003 Strategic Environmental Assessment SEA4 Analysis of macroinvertebrate samples from the Northern Triangle area (north UKCS)

This report is a contribution to the Strategic Environmental Assessment (SEA4) conducted by the Department of Trade and Industry (now Department of Energy and Climate Change) and it presents results from the macrofaunal analysis of sixty-three macrobenthos samples. The samples were from a range of depths in the SEA4 Northern Triangle area, at the northernmost extent of British waters. Most of the samples were rich in terms of numbers of taxa and individuals and all major benthic invertebrate phyla were represented in the survey. The fauna included several taxa that are likely to be undescribed species and many have been recorded by nominal names. Several groups have also been left at higher taxonomic levels. Data analysis was not included for this part of the project. A preliminary literature list for deep-sea taxonomy was compiled for the project and provided in the report. A spreadsheet of data is also available.
