Most of the sampling was conducted aboard the RV *Cefas Endeavour* using a variety of methods deemed compatible with the sedimentary habitat being targeted. At each station three replicate samples was collected, all within close proximity of each other. From each sample, a sub-sample of sediment was removed for sediment particle size distribution analysis. Macrofauna were extracted by sieving the collected sediments and viewing the residue under light magnification. Animals were identified to the lowest possible taxonomic level and each taxon enumerated and weighed. Tidal parameters were generated using a 3D hydrodynamic model (Davies and Aldridge, 1993), run in depth-integrated form on an approximately 3.5 km resolution grid covering the European continental shelf. Average and peak wave stress were calculated from a one-year model run covering the period September 1999 to September 2000, on an approximately 12km grid, using the WAM spectral wave model run at the Proudman Oceanographic Laboratory. Surface chlorophyll a concentration images, derived from MERIS satellite ocean colour data using the ‘Chlorophyll-II’ algorithm for case-II waters (Doerffer and Schiller, 2007), were used to derive mean surface chlorophyll a concentrations between 2002 and 07 Productivity estimates (i.e., P:B ratio (yr ... ) and total production (kJ m ... yr ... )) were derived in a stepwise approach from the raw abundance and biomass data (for Objective 5). Firstly, standardised biomass records were converted to energy values using published conversion factors. Energy values were then converted to production values using a spreadsheet freely available on the Internet ( `http://www.awi-bremerhaven.de/benthic/ecosystem/foodweb/handbook/`_ ) (Brey, 2001). .. _`http://www.awi-bremerhaven.de/benthic/ecosystem/foodweb/handbook/`: http://www.awi-bremerhaven.de/benthic/ecosystem/foodweb/handbook/
