UKOA measurements of the stable isotope composition of dissolved inorganic carbon in the Northeastern Atlantic and Nordic Seas during summer 2012.

This dataset contains 227 measurements of the stable isotope composition of dissolved inorganic carbon in seawater in samples collected during cruise JR20120601 in the Northeastern Atlantic and Nordic Seas in June 2012. Sample analysis was carried out at the Scottish Universities Environmental Research Centre - Isotope Community Support Facility in East Kilbride, UK. The results fall in a range from -0.58 to +2.37 per mille, relative to the Vienna Peedee Belemnite internation standard. The measurement precision, calculated from measurements of samples collected in duplicate, is 0.07 per mille.
