EXAMINATION OF BULK SOIL/DETRITAL CHARCOAL AND AMS RADIOCARBON AGE DETERMINATION OF MATERIAL FROM SITES TRCR1, TRCR2, TRCR4, TRCR5, AND TRCR6 ALONG TAYLOR RIVER, COLORADO.
Six bulk soil samples and seventeen detrital charcoal samples from sites TRCR1, TRCR2, TRCR4, TRCR5, and TRCR6 along Taylor River in Gunnison County, central Colorado, were analyzed to recover organic remains suitable for radiocarbon age determination. Samples were collected from Holocene terraces a
Phenology of selected cavity-nesting Hymenoptera and flowering plant taxa in the Colorado Rocky Mountains from 2008 to 2010.
Data come from fourteen sites in the West Elk Mountains of Colorado, USA. The study aimed to identify the factors regulating phenology of plants and cavity-nesting insects, and to determine the likelihood of asynchrony between flowering and pollinator emergence under climate change. Numbers of flowe

Estimated Darcy Velocities Using Temperature Time Series for Meander A of East River, Colorado.
Heat was used as a tracer to quantify seasonal changes in vertical Darcy velocity through the streambed at three different locations about Meander A of East River, Colorado. The file Raw_Temp.csv represents raw temperature data (in degrees Celsius) collected from the three locations, A, B, and C, at
Depth-resolved seasonal porewater chemistry measurements from 3 locations around Meander A of the East River, Colorado
Depth-resolved pore water samples were recovered from 3 locations around Meander A in the East River near Crested Butte, CO, USA for a suite of physiochemical analyses. Supplemental_Information.csv contains water quality measurements including pH, conductivity, temperature, ORP, TDS, O2 concentratio
Distributed hydrological, chemical, and microbiological measurements around Meander A of East River, Colorado.
In July-August 2018, we collected 88 filtered pore water samples at 20 cm depth and analyzed them for anions, cations, dissolved organic carbon, dissolved organic matter (DOM) quality, and standard water quality parameters. Vertical hydraulic head gradients were measured to assess the potential for
Geochemical exports to river from the intrameander hyporheic zone under transient hydrologic conditions, Water Resources Research: Dataset.
To understand how redox processes influence carbon, nitrogen, and iron cycling within the intrameander hyporheic zone, we developed a biotic and abiotic reaction network and incorporated it into the reactive transport simulator PFLOTRAN. Two dimensional reactive flow and transport simulations were p
Distinct Source Water Chemistry Shapes Contrasting Concentration Discharge Patterns, Water Resources Research: Dataset.
This data package contains discharge and water quality data and model results at Coal Creek Watershed in the central Rocky Mountains of Colorado, USA. Files include high-frequency stream chemistry data collected during the period of Dec 2015 to Jun 2018, and model results of water storage and flux.
Sub-Basin Delineation for the Upper East River, Colorado, United States.
Upper East sub-basins are delineated as area contributing flow to SFA 2016 stream gage locations. Shapefile attributes include sub-basin ID, name, area (m2 and km2) and codes for spatial contributions to EBC and PH used by Carroll et al. (2018). Geospatial reference is UTM 1983 zone 13.

Annual floodplain sediment deposition recorded using feldspar clay marker horizons along the East River, Colorado, 2015-2017.
White feldspar clay was placed along 24 transects defining a ~9-km long study reach along the meandering snowmelt-dominated East River in Colorado, USA. Feldspar markers horizons were placed in the fall of 2015 and 2016 along transects with the space between them increasing with distance from the ch
Sample Collection Metadata for Soil Cores from the East River Watershed, Colorado collected in 2017.
This data package contains sample collection metadata for soil cores from the East River Watershed in Colorado used in biogeochemical analyses by the Watershed Function SFA. Soil cores were collected seasonally during autumn, winter, snowmelt, and spring at a predominately montane meadow, high altit
Depth and elevation of floodplain fine sediment along the East River near Crested Butte, Colorado measured in 2016 and 2017.
The depth of floodplain fine sediment was measured at 1,601 points along the East River near Crested Butte, Colorado spanning a study reach approximately 800 m in length in 2016 and 2017. These depths are being used to estimate the volume of floodplain sediment present along the study reach, convert
