Section 3 <strong>Environmental</strong> Baseline<br />

Polychaete dominance can be considered typical of North Sea sediments, <strong>and</strong> they are generally<br />

found to account for approximately 50% (Eleftheriou <strong>and</strong> Basford, 1989). This pattern of polychaete<br />

dominance was also recorded in previous surveys of the area (Gardline 2007; 2009).<br />

The results of the macrofaunal survey suggest this community within the proposed development area<br />

is highly diverse with 289 taxa being represented in the samples collected along the proposed pipeline<br />

route. The 289 taxa were made up of 124 Polychaeta, 69 Crustacea, 63 Mollusca, 15 Echinodermata<br />

<strong>and</strong> 18 others including sea pens <strong>and</strong> anemones (Gardline, 2011). The variation in the faunal<br />

community recorded over the pipeline route survey appeared to correlate with changes in sediment<br />

characteristics, most notably the proportions of finer sediments (
