δ15N-PN, δ13C-PC, particulate organic nitrogen and particulate organic carbon measurements from CTD niskin-collected water column profiles obtained in the Barents Sea during NERC CAO cruise JR16006, July-August 2017.

This dataset contains δ15N-PN and δ13C-PC data, together with PON and POC concentrations collected at 23 stations in the Barents Sea during cruise JR16006 (RSS James Clark Ross, 7th July to 7th August 2017). This cruise was part of the National Environment Research Council funded Changing Arctic Ocean Programme (www.changing-arctic-ocean.ac.uk). δ15N-PN (o/oo) and PON (μg/L) were collected using CTD-mounted Niskin bottles from the top 300 m of the water column and δ13C-PC (o/oo) and POC (μg/L) from surface samples (upper 15 m). Samples were analysed using an Elemental Analyser - Isotope Ratio Mass Spectrometer (EA-IRMS) at the University of Liverpool.
