Samples for the assessment of total organic carbon and total nitrogen (TOC and TN) content in the sediment on the Northeast Greenland shelf have been collected with R/V Polarstern during PS109 between September and October 2017 using a camera-equipped multiple corer (TV-MUC; core area 0.007 m²). Upon arrival on deck, the upper 5 cm of three MUC cores were sliced into 1cm intervals, using a cut-off syringe, and then stored at -20°C. The samples were dried at 60°C, subsequently treated with hydrochloric acid in order to remove the inorganic carbon until the sediment was not bubbling anymore, and then dried again at 60°C. Finally, percent TOC and TN were determined using an ELTRA CS2000 Carbon Analyzer.
