22 stations on and around the Brown Bank were selected to study local ecological variation and to link ecological with geomorphological data. Macrobenthos was collected with a box corer and identified to the lowest possible taxonomic level, in three replicates per station. Sediment characteristics (grain size, TOC, chlorophyll α etc.) were measured for each replicate. Geomorphological data (bathymetry, backscatter, BPI etc.) were derived from multibeam echosounding at each station.
