Sediment community responses to marine versus terrigenous organic matter in the Whittard canyon, supplement to: Hunter, William Ross; Jamieson, Alan J; Huvenne, Veerle A I; Witte, Ursula (2013): Sediment community responses to marine vs. terrigenous organic matter in a submarine canyon. Biogeosciences, 10, 67-80


The Whittard canyon is a branching submarine canyon on the Celtic continental margin, which may act as a conduit for sediment and organic matter (OM) transport from the European continental slope to the abyssal sea floor. In situ stable-isotope labelling experiments (JC36-042-Spre01; JC36-100-Spre01) were conducted in the eastern and western branches of the Whittard canyon testing short term (3 - 7 day) responses of sediment communities to deposition of nitrogen-rich marine and nitrogen-poor terrigenous phytodetritus. Isotopic labels were traced into faunal biomass and bulk sediments, and the bacterial polar lipid fatty acids (PLFAs). These data files provide the data on macrofaunal and bacterial uptake of the isotopically-labelled organic carbon and nitrogen, and macrofaunal community composition at the two stations within the Whittard canyon
