| Summary: | 1. Pelagic and benthic systems usually interact, but their dynamics and production rates differ. Such differences influence the distribution, reproductive cycles, growth rates, stability and productivity of the consumers they support. Consumer preferences for, and dependence on, pelagic or benthic production are governed by the availability of these sources of production and consumer life history, distribution, habitat, behavioural ecology, ontogenetic stage and morphology. 2. Diet studies may demonstrate the extent to which consumers feed on prey in pelagic or benthic environments. But they do not discriminate benthic production directly supported by phytoplankton from benthic production recycled through detrital pathways. The former will track the dynamics of phytoplankton production more closely than the latter. 3. We develop and apply a new analytical method that uses carbon (C) and sulfur (S) natural abundance stable isotope data to assess the relative contribution of pelagic and benthic pathways to ... : Sulphur stable isotope data for North Atlantic (North Sea) fishesSulphur stable isotope data were collected for the study of food webs and benthic-pelagic coupling in the North Sea. They comprise natural abundance stable isotope measurements of δ34S for 415 individuals from 15 species of fish sampled in 2006. Measurements of δ13C and δ15N for the same individuals were previously published by Jennings and Cogan (2015). A numeric code is included with the present data to allow the δ34S measurements to be matched to the δ13C and δ15N measurements by individual. Trophic level estimates for the same individuals, based on δ15N measurements, are provided in Supplementary Material supporting Jennings and van der Molen (2015).
