Dissolved rhenium and other dissolved ions in Alpine catchments of the Erlenbach and Vogelbach (Switzerland) and the East River (Colorado, USA) (NERC Grant NE/I001719/1)

The measurements and data contained here were obtained to study the chemical weathering of sedimentary rocks, and more specifically the oxidation of rock organic carbon and the associated release of CO2. The primary aim was to better understand the production and mobility of the trace element rhenium during weathering, because this element has been proposed as a proxy for rock organic carbon oxidation. The study focused on three Alpine catchments that drain sedimentary rocks, which all experience moderate to high erosion rates where oxidative weathering rates are thought to operate faster. Two catchments were located in Switzerland - the Erlenbach and Vogelbach, and one catchment in Colorado, USA - the East River. To study chemical weathering and the production and mobility of rhenium, a suite of samples were collected to capture the source and products of weathering reactions. These focused on stream and river water, river sediments and weathering profiles collected on sedimentary rocks. The Swiss catchments, water samples were collected from 2011 and 2012 to capture changes in river flow and seasonal changes in hydro-climate. Samples were collected from a gauging station operated by the Swiss Federal Institute for Forest, Snow and Landscape Research - WSL. In the East River, samples were collected from the gauging station operated by the Lawrence Berkeley National Laboratory Watershed Function Scientific Focus Area from 2015 and 2016. Additional samples included snow samples collected from the Erlenbach. All water samples were analysed for their major dissolved ion content by Ion Chromatography. Dissolved rhenium concentrations were determined by High Resolution and Quadrupole Inductively Coupled Plasma Mass Spectrometry. Solid samples were digested and analysed for Re content by ICP-MS. These geochemical measurements were paired with water discharge data to quantify the flux of dissolved elements, using rating curves and flux-weighted average methods, and interpret the hydrological context of ion production and mobility through the landscape. This new data acquisition was funded by a European Research Council Starting Grant to Robert Hilton (ROC-CO2 project, grant 678779) and a Natural Environment Research Council (NERC), UK, Standard Grant (NE/I001719/1). Further details of subsequent data analysis and interpretation can be found in Hilton, R.G., et al., 2021, Concentration-discharge relationships of dissolved rhenium in Alpine catchments reveal its use as a tracer of oxidative weathering, Water Resources Research

Statement
Water samples were collected and filtered through 0.2micron filters and refrigerated prior to analysis. Major ion concentrations were determined by Ion Chromatography and rhenium concentrations by ICP-MS. Solid samples (river bed loads, weathered shale) were ground and digested using HF and HNO3. Rhenium concentrations were determined by ICP-MS. Precision and accuracy assessed by parallel digestion and analysis of a number of in-house and international certified standards, which included standards with similar matrix to those analysed here (sedimentary rocks). Dissolved ion data was plotted with water discharge and power law fits were used as rating curves. Fitting was done in Origin Pro using least squares regression. Power law fits and uncertainties on pre-factor and exponents were applied to water discharge records to quantify flux. A flux-weighted average method was also used.
