The dataset includes water content, total nitrogen (TN), total carbon (TC), total organic carbon (TOC), total inorganic carbon (TIC), and carbon and nitrogen isotopic signatures (d13C, d15N) in marine sediments. Samples were collected during the Nansen Legacy Joint Cruise 2-2 in August/September in the northern Barents Sea; cruise 2021710 (JC2-2). Short sediment cores were subsampled from three replicate deployments of a giant box corer at stations P7, P8, P9 and P11. At P10, only two deployments were completed. The sediment cores were sliced into 1cm-layers (0 - 6 cm) and immediately stored at -20°C onboard. All samples were freeze-dried in the laboratory of the Department of Geosciences (University of Oslo). Subsequently, approximately 1g of homogenised, freeze-dried sediment from each core interval was ground for total carbon (TC), total organic carbon (TOC), total nitrogen (TN), and their stable carbon (δ13C) and nitrogen (δ15N) isotopic signature measures. Elemental analysis was undertaken with an ...
