    Biogeochemical responses of intertidal sediments to simulated warming and epi-faunal loss: a mescosm experiment (2018)
    PANGAEA
    In:  Supplement to: Hunter, William Ross; Ogle, Neil; O'Connor, Nessa (2019): Warming affects predatory faunal impacts upon microbial carbon cycling. Functional Ecology, https://doi.org/10.1111/1365-2435.13304

    Description: Ocean warming and the disproportionate loss of larger (often predatory) fauna are major threats to seabed (benthic) ecosystem functioning. In a mescosm study we tested how faunal species loss affects microbial carbon sequestration and retention in intertidal sediments, under both ambient and predicted warming conditions (ambient + 2 deg C), whilst manipulating the presence/absence of the shore crab Carcinus maenas. We used stable isotope pulse-chase techniques to trace the fixation and retention of a fixed dose of 13C-labelled sodium bicarbonate within sediment organic matter and microbial biomass. These datasets include the environmental conditions (Temperature, Salinity, Oxygen Concentrations and pH) within the mesocosms and the biogeochemical responses of the surfical (00-0.5 cm) sediment layer. This includes changes in chlorophyll a concentrations and chlorophyll a patchiness over time, differences in concentrations and 13C-enrichment of the sediment Total Organic Carbon (TOC) and microbial Polar Lipid Fatty Acid (PLFA) between treatments, and profiles of the relative abundance of the individual PLFAs and 13C-labelled PLFAs (in molar %).

    Sediment community responses to marine versus terrigenous organic matter in the Whittard canyon (2013)
    PANGAEA

    Description: 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
