Long-term field observation of shrubland ecosystem in Wyoming, USA from 2008-2018 Long-term field observation of shrubland ecosystem in Wyoming, USA from 2008-2018
The importance of monitoring shrublands to detect and understand changes through time is increasingly recognized as critical to management. This dataset focuses on ecological change observation over ten years of field observation at 134 plots within two sites that are located in Southwestern of Wyoming, USA from 2008-2018. At sites 1 and 3, 134 long-term field observation plots were...
High Resolution Aeromagnetic Survey, Villa Grove, Colorado, USA, 2011 High Resolution Aeromagnetic Survey, Villa Grove, Colorado, USA, 2011
This data release includes data collected from the Villa Grove helicopter magnetic survey in northern San Luis Valley and Poncha Pass region in south-central Colorado, USA. The survey area extends over the northern part of Great Sand Dunes National Park, Poncha Pass and vicinity, and into the southern end of the Upper Arkansas Valley. It includes the communities of Crestone, Villa Grove...
Lumped parameter models of groundwater age from the Columbia Plateau Aquifer, Vertical Flowpath Study Network Lumped parameter models of groundwater age from the Columbia Plateau Aquifer, Vertical Flowpath Study Network
This data release documents two Microsoft Excel tables that contain data for understanding tracer concentrations and groundwater age in the Columbia Plateau aquifer system. Results for geochemical correction of carbon-14, and lumped parameter modeling of groundwater age for the sample network (VPFS, vertical flow path study) are described. Geochemical carbon-14 correction results (RFG)...
Lumped parameter models of groundwater age and noble gas models of recharge conditions in support of Groundwater and Surface-Water Resources near Red Fleet Reservoir, Uintah County, Utah Lumped parameter models of groundwater age and noble gas models of recharge conditions in support of Groundwater and Surface-Water Resources near Red Fleet Reservoir, Uintah County, Utah
This data release documents four Microsoft Excel tables; one contains data for understanding water ages, one contains noble gas model data, two that describe the data fields. Results described include environmental tracer concentrations (tritium, tritiogenic helium-3, choloroflourocarbons, and radiogenic helium-4), mean age and age distribution, noble gas concentrations, and groundwater...
Lumped parameter models of groundwater age, Spanish Valley Watershed, Grand and San Juan Counties, Utah Lumped parameter models of groundwater age, Spanish Valley Watershed, Grand and San Juan Counties, Utah
This data release documents two Microsoft Excel tables; one contains data for understanding groundwater ages in the Spanish Valley watershed, and one that describe the data fields. Mean ages and age distributions from 19 groundwater samples were estimated in support of an evaluation of the groundwater resources of the Spanish Valley watershed (Masbruch and others, 2019). Individual...
Noble gas isotopes and lumped parameter model results for environmental tracer based groundwater ages, South Rim Grand Canyon, Arizona, USA Noble gas isotopes and lumped parameter model results for environmental tracer based groundwater ages, South Rim Grand Canyon, Arizona, USA
This data release documents three Microsoft Excel tables; one contains noble gas isotopic data, one contains data for understanding groundwater ages in the South Rim of the Grand Canyon, and one that describe the data fields. Results described include raw noble gas concentrations, environmental tracer concentrations (tritium, tritiogenic helium-3, sulfur hexafluoride, carbon-14, and
