Sulfur x-ray absorption spectroscopy data from bedrock shale, soil, and floodplain sediment from the East River, Colorado watershed.
This dataset includes sulfur x-ray absorption near edge spectroscopy (XANES) data collected on solid samples as a part of the Watershed Function Scientific Focus Area (SFA) located in the Upper Colorado River Basin. The data were collected in order to investigate the speciation of sulfur and degree
Stable isotopes of carbon dioxide (CO2), dissolved inorganic carbon (DIC), water and concentrations of greenhouse gases in a mountainous watershed (Crested Butte, Colorado).
Temperature and precipitation variability in response to climate change affects water cycling of watersheds and can potentially impact water quality, water availability, elemental and molecular fluxes, and biogeochemical processes. Here we report the measurements of light stable isotopes and greenho
SnowEx20 Grand Mesa Autumn 2019 Gravimetric Soil Moisture, Version 1
SnowEx20 Grand Mesa In Situ Dielectric Soil Moisture, Version 1
Data release for Surficial Geology of the Northern San Luis Valley, Saguache, Fremont, Custer, Alamosa, Rio Grande, Conejos, and Costilla Counties, Colorado
The San Luis Valley and associated underlying basin of south-central Colorado and north-central New Mexico is the largest structural and hydrologic basin of the Rio Grande Rift and fluvial system. The surrounding San Juan and Sangre de Cristo Mountains reveal evidence of widespread volcanism and tra

Effects of flowers on land surface albedo and soil microclimate
The phenology of vegetation, namely leaf-out and senescence, can influence the Earth’s climate over regional spatial scales and long time periods (e.g., over 30 years or more), in addition to microclimates over local spatial scales and shorter time periods (weeks to months). However, the effects of
Total metals & anion concentration data; Slate River floodplain, Crested Butte, CO; May 2020-September 2020
This data package includes processed and undiluted measurements for metal and anion concentrations from pore water (groundwater) samples from the Slate River floodplain of Crested Butte, CO, a focus field site for the SLAC Floodplain Hydro-Biogeochemistry SFA. The data was generated as part of the w
Specific conductivity, pH, dissolved oxygen, water temperature, alkalinity and sulfide in-situ data; Slate River floodplain, Crested Butte, CO; May 2020-October 2020
This data package includes a time-series of field measurements from May to October 2020 in groundwater and surface water from the Slate River floodplain in Crested Butte, CO, a focus field site for the SLAC Floodplain Hydro-Biogeochemistry SFA. The data was generated as part of the work targeting th
Biomass Inventories at Harvard Forest EMS Tower since 1993
In 1993, we installed 40 circular, 10 m radius biometric plots in the footprint of the EMS tower on Prospect Hill. We randomly placed the plots within 100 m increments along ten 500 m transects that extend from the tower in the northwest and southwest directions. In 2001, we removed three plots (G3,
Qinayan/Soil-thickness: Soil thickness estimation
This release includes Python codes and associated field sampling and remote sensing data for the estimation of the spatial distribution of soil thickness in two hillslopes in the Pump House area in the East River Watershed in the CO., the U.S.
The Relationship between Soil Properties and Variation in the Morphology and Phenology of non-native mustard plant <i>Thlaspi arvense</i> in Subalpine Meadows
The ability of soil to retain moisture can significantly impact the severity of droughts on plants. Deep, loamy soils retain moisture from snow melt into the dry season more efficiently than shallow, sandy soils that lose water to runoff and percolation. Soil depth and texture are thus significant i
Relationships between CO2, thermodynamic limits on silicate weathering, and the strength of the silicate weathering feedback
Multiple models and experiments underscore large uncertainty in soil carbon dynamics
Soils contain more carbon than plants or the atmosphere, and sensitivities of soil organic carbon (SOC) stocks to changing climate and plant productivity are a major uncertainty in global carbon cycle projections. Despite a consensus that microbial degradation and mineral stabilization processes con
Pocket gopher (<i>Thomomys talpoides</i>) soil disturbance peaks at mid-elevation and is associated with air temperature, forb cover, and plant diversity
Burrowing mammals can be ecosystem engineers by increasing soil aeration and erosion and altering the structure of plant communities. Studies that characterize the constraints on the distributions of fossorial mammal disturbances to soil can help predict changes in ecosystem engineering under future
A molecular investigation of soil organic carbon composition across a subalpine catchment
The dynamics of soil organic carbon (SOC) storage and turnover are a critical component of the global carbon cycle. Mechanistic models seeking to represent these complex dynamics require detailed SOC compositions, which are currently difficult to characterize quantitatively. Here, we address this ch
Gunnison County Planning Planning Commission Mapping Project
Tasks Construction of interpretative overlay maps for the private lands in Gunnison County from the Soil Con- servation Service's photographic detailed soil maps. These overlays are to be used with the available Ue. S- Forest Service overlay map set prepared for ; the draft Model Transportation Plan
