'Primary productivity, biomass yields and fish capture rates have undergone large changes within the ECS  over the past decades .' 'Changing sea temperatures have influenced the abundance of phytoplankton, benthic biomass, cephalopod fisheries and the size of demersal trawl catches in the northern SCS  observed over the period 1976-2004 .' 'Concurrent with the retreat of the 'cold pool'  on the northern Bering Sea shelf,  bottom trawl surveys of fish and invertebrates show a significant community-wide northward distributional shift and a colonisation of the former cold pool areas by sub-Arctic fauna .' 'Observed changes in the phenology of plankton groups in the North Sea over the past 50 years are driven by climate forcing, in particular regional warming .'
