Based on in situ microprofiles, chamber incubations and eddy covariance measurements, we investigated the benthic carbon mineralization and nutrient regeneration in a ~65-m-deep sedimentation basin of Loch Etive, UK. The sediment hosted a considerable amount of infauna that was dominated by the brittle star . The numerous burrows were intensively irrigated enhancing the benthic in situ O uptake by ~50 %, and inducing highly variable redox conditions and O distribution in the surface sediment as also documented by complementary laboratory-based planar optode measurements.
