The benthic biomass values of various trophic groups were studied for the first time at the scale of the entire Bay of Seine (50 x 100 km) in the eastern English Channel. Sampling was carried out before and after the winter of 1999. In both cruises the suspension feeders dominated (66% of the 12 gAFDW m(-2) in 1998 and 56% of the 10 gAFDW m(-2) in 1999).The common European ophiuroid Ophiothrix fragilis was the most important contributor to total biomass. The repartition of its patches (sometimes > 20 gAFDW m(-2) cannot be explained by the environmental parameters recorded (viz., granulometry, organic matter and pigment content).
