Irish River Isotopic Composition

This resource presents δ18O, δ2H and d-excess values of 40 Irish river surface water in eight sampling campaigns from 2018-2020. Samples were collected in 20 mL HDPE scintillation vials with no headspace for transport back to The Ohio State University, Columbus, Ohio, USA, where they were analyzed on a Picarro Wavelength Scanned-Cavity Ring Down Spectroscopy Analyzer Model L2130-i. Instrument precision was 0.016‰ for δ18O and 0.15‰ δ2H. In-run accuracy for samples was determined with sample duplicates and values were ≤0.83‰ and ≤2.5‰ δ18O and δ2H, apart from one run where the δ2H precision of March 2019 samples is ≤3.9‰. Sample location in the form of latitude and longitude is included for all samples except for two Connemara Bog locations.
