ABSTRACT:
Data were collected at variable frequencies between 2012 and 2022. Rain water was collected from 2013 to 2016 near the towns of Stanford, Moccasin, and Moore, MT using precipitation collectors and a mineral oil coating to limit evaporation (Product Alternatives, Inc.; Fergus Falls, MN). Snow water was collected in 2014 near Moore, MT and from 2019 to 2022 near Moccasin, MT using a 10 cm-diameter metal core inserted vertically in the snowpack to sample the entire snow column. Snow samples were sealed in Ziploc bags, weighed, and allowed to melt before thorough mixing and pouring an aliquot into 20 mL scintillation vials. A monthly precipitation composite sample was collected from 2021-2022 near Moccasin, MT. Terrace soil water was collected from 2013 to 2016 in a privately owned field near Moore, MT using porous cup tension lysimeters (PTFE/silica; Prenart Equipment; Frederiksberg, Denmark). Terrace groundwater was collected from 2013 to 2022 from wells and springs across the Moccasin terrace landform. Riparian groundwater and surface water were collected from 2020 to 2022 from three stream corridors on the Moccasin terrace. Stream water was collected from 2012 to 2022 from streams on the Moccasin terrace. All groundwater and surface water were sampled using a peristaltic pump (Geotech Environmental Equipment; Denver, CO) and pumped through a 0.45-μm capsule filter (Geotech Environmental Equipment; Denver, CO) into 20 mL glass scintillation vials. Data were collected to assess water isotopic compositions of precipitation and landscape water to understand soil, aquifer, and stream hydrological processes and integration of source waters in a semi-arid, non-irrigated agricultural landscape.
