Dataset abstract This dataset contains particulate organic carbon and particulate organic nitrogen concentrations and stable isotope composition (delta 13C and delta 15N) sampled during the Antarctic Circumnavigation Expedition (ACE) Leg 1-3. Water samples were collected from the underway seawater supply every 3 hours, filtered onto pre-combusted glass fibre filters, acidified to remove inorganic compounds and analysed for both elements on the same filter using an elemental analyser. These samples provide an estimate of the organic carbon and organic nitrogen concentration and carbon and nitrogen stable isotope composition of living and detrital particles > 0.7 micrometres in size.

This research was partially supported by the Australian Government through the Australian Research Council's Discovery Projects funding scheme (project DP160103387), a South African CSIR Parliamentary Grant (SNA2011112600001) and the CSIR Southern Ocean Carbon and Climate Observatory (SOCCO) programme. Sample analysis was performed by the Stable and Light Isotope Laboratory, Department of Archaeology, University of Cape Town.
