Sampling took place in April and May 1993, and in February and May 1994. Samples of benthic macrofauna were collected from MAFF research vessels at each of 25 'intermediate' and 'offshore' stations around England and Wales coastline, following the guidelines of the National Monitoring Program. One station in the south west Approaches was samples in 1992, i.e. outside the recommended February to May sampling window, but this offshore, deep-water environment was included as a clean-water reference point. At each location, five sediment samples for macrofauna analysis were collected using a 0.1 m2 day grab from the central point of a 500 m grid of 9 stations, the latter being sampled for contaminant analyses only.were also obtained by MAFF research vessels from 69 stations between 1992 and 1996. A standard 2 m Lowesoft beam trawl with a 3 mm mesh codend liner was deployed for 5-10 min across each station at a speed of about 0.5 m/s. Samples provide unambiguously quantitative data which can be easily linked with sediment type within the small unit area of the sample. Trawls provided integrated samples of the fauna over a much larger area.infaunal assemblages were encountered on both the eastern and western UK coasts in comparable environmental conditions. Tidal current velocity and sediment characteristics account for a significant amount of the observed variability in species richness and densities. There was no evidence of any adverse effects on these measures of assemblage structure arising from trace metal contamination of sediments. A single station representative of coarser deposits off the Humber estuary supported a rich and distinctive fauna characterized by the presence of the reef-building polychaete Sabellaria spinulosa. This survey was collated by MarLIN as part of a data collation contract for species on the provisional list of Nationally Important Marine Features.
