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 <sup style="box-sizing:
border-box; font-size: 75%; line-height: 0; position: relative; top: -0.5em;
vertical-align: baseline;">...</sup> ) and total production (kJ m <sup
style="box-sizing: border-box; font-size: 75%; line-height: 0; position:
relative; top: -0.5em; vertical-align: baseline;">...</sup> yr <sup
style="box-sizing: border-box; font-size: 75%; line-height: 0; position:
relative; top: -0.5em; vertical-align: baseline;">...</sup> )) 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).
