ABSTRACT:

This dataset includes inorganic chemistry and stable water isotope measurements of the Olentangy River and two subsurface pipe networks that drain The Ohio State University campus in Columbus, Ohio. Data were collected from November 2021 - November 2022 on a weekly or biweekly basis. Samples were collected for major cation (Na, K, Ca, Mg), anion (F, Cl, Br, SO4), nutrient (N-NO3, soluble reactive phosphorus) and dissolved silica. Additional samples were collected with no headspace for δ18O and δ2H measurements. All samples were collected with a sample poll device that was rinsed 3 times with sample water prior to collection. Samples for ion, nutrient, and dissolved silica analysis were filtered within 12 hours.

These data were originally published in the following reference, and further information may be found within:

ABSTRACT:

This resource presents δ18O, δ2H and d-excess values of the samples collected along the transect of the Scioto River in Ohio, USA. Samples were collected on weekly, bi-weekly, and monthly scales depending on time of year and location. We also present δ18O, δ2H and d-excess data from samples collected from 26 Ohio Rivers during five sampling campaigns from 2019 – 2021. Samples were collected in by hand in 20 mL HDPE scintillation vials or with a 1 L HDPE Bottle attached to a 1 m PVC pole. Samples were stored 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 ≤0.52‰ and ≤1.1‰ δ18O and δ2H, apart from one run where the δ2H expect for 2020 Ohio River samples where in-run accuracy was ≤3.4‰. All data are published in Supplementary Table 1 in the initial resource:

ABSTRACT:

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.

Data are published as Table S1 and Table S2 in initial resource:

ABSTRACT:

This resource presents δ18O, δ2H and d-excess values of central Ohio precipitation from 2012 – 2018. Samples were collected in open bucket collectors at Mansfield (40.7639°, -82.5039°), Galena (40.2151°, -82.8799°); and Columbus (40.0522°, -83.0093°). Collectors were placed in uncovered locations and sample was collected immediately after the precipitation event to minimize evaporation. Samples were analyzed on a Picarro Wavelength Scanned-Cavity Ring Down Spectroscopy Analyzer Model L1102-i or Model L2130-i. Measurement accuracy for samples was ≤3.4% and ≤4.2% for δ18O and δ2H, respectively (Leslie et al., 2014). When available, the corresponding precipitation amount, daily average air temperature, relative humidity, ground wind speed, ground wind direction are presented for samples collected in Columbus. Climate data were retrieved from the Ohio Agricultural Research and Development Center in Columbus Ohio [OARDC Weather System http://www.oardc.ohio-state.edu].
