Digital 3-D Geologic Framework data for the Rio Grande Transboundary region of New Mexico, Texas, USA and Northern Chihuahua, Mexico
This digital dataset of a three-dimensional hydrogeologic framework for the Rio Grande Transboundary region of New Mexico, Texas, USA and Northern Chihuahua, Mexico defines the geometry, extent, and character of aquifers of the region and is intended as the digital hydrogeologic input data for numerical simulation of the groundwater system.
The data consist of a single GeoDatabase (RGTIHM_3DHFM
Geochemical and geochronologic data from the Hall Creek caldera, Toiyabe Range, Nevada
The magmatic, tectonic, and topographic evolution of what is now the northern Great Basin remains controversial, notably the temporal and spatial relation between magmatism and extensional faulting. This controversy is exemplified in the northern Toiyabe Range of central Nevada, where previous geologic mapping suggested the presence of a caldera that sourced the late Eocene (34.0 mega-annum [Ma])
Stratigraphic, geochemical, and hydrologic data for the Boston Peak wetland, Larimer County, CO, USA
Comprehensive sampling of peat, underlying lakebed sediments, and coexisting waters of a naturally uraniferous montane wetland are combined with hydrologic measurements to define the important controls on uranium (U) supply and uptake. The major source of U to the wetland is groundwater flowing through locally fractured and faulted granite gneiss of Proterozoic age. Dissolved U concentrations in f
Data for a Comprehensive Survey of Fault Zones, Breccias, and Fractures in and Flanking the Eastern Espanola Basin, Rio Grande Rift, New Mexico
This release provides the data for a comprehensive survey of geologic structures in the eastern Espaola Basin of the Rio Grande rift, New Mexico. The release includes data and analyses from 53 individual fault zones and 22 other brittle structures, such as breccia zones, joints, and veins, investigated at a total of just over 100 sites. Structures were examined and compared from poorly lithified T
Statistically-downscaled monthly historical (1901-2000) CRU TS 2.1 and projected future (2001-2099) CMIP3 A2 and A1B simulated temperature, precipitation, and sunshine data on a 30-second grid of the northwest United States and southwest Canada, version 1
This data set consists of monthly mean temperature (degrees C), total precipitation (mm), and possible sunshine (%) data statistically downscaled onto a 30-second grid of the northwest United States and southwest Canada. Historical climate data for 1901-2000 were developed from the CRU CL 1.0, CRU CL 2.0, and CRU TS 2.1 data sets (http://www.cru.uea.ac.uk/cru/data/hrg/). Projected future climate d
Bioclimatic variables calculated from statistically-downscaled historical (1901-2000) CRU TS 2.1 climate data and projected future (2001-2099) CMIP3 A2 and A1B simulated climate data on a 30-second grid of the northwest United States and southwest Canada,

LPJ biomes (30-year mean) simulated using monthly historical (1901-2000) CRU TS 2.1 climate data and projected future (2001-2099) CMIP3 A2 and A1B simulated climate data on a 30-second grid of the northwest United States and southwest Canada, version 1.0
This data set consists of biomes (30-year mean) simulated using LPJ, a dynamic global vegetation model (Sitch et al. 2003, Global Change Biology 9:161-185), for a 30-second grid of the northwest United States and southwest Canada. Shafer et al. (2015, PLoS ONE 10: e0138759) describe the methods used to create the biome data. LPJ was run for 1901-2000 using historical climate data developed from th
