Digital subsurface data of Paleozoic rocks in the Upper Colorado River Basin in Wyoming, Utah, Colorado, Arizona, and New Mexico from USGS Regional Aquifer System Analysis

The Upper Colorado River Basin has a drainage area of about 113,500 square miles in western Colorado, eastern Utah, southwestern Wyoming, northeastern Arizona, and northwestern New Mexico. In the 1980’s and 1990’s, the Upper Colorado River Basin was a study area under of the U.S. Geological Survey's Regional Aquifer-System Analysis (RASA) program (Sun and Johns

Data from a sequential selective dissolution method to quantify storage and stability of organic carbon associated with Al and Fe hydroxide phases

Stabilization of SOM (soil organic matter) is regulated in part by sorption and desorption reactions happening at mineral surfaces, as well as precipitation and dissolution of organo-metal complexes. Fe and Al hydroxides play a particularly significant role in SOM stabilization in soils due to their ubiquitous distribution and their highly reactive surface properties. Iron and Al hydroxides...

Data release for Linking land and sea through an ecological-economic model of coral reef recreation

Coastal zones are popular recreational areas that substantially contribute to social welfare. Managers can use information about specific environmental features that people appreciate, and how these might change under different management scenarios, to spatially target actions to areas of high current or potential value. We explored how snorkelers’ experience would be affected by sepa

Tracking disturbance and inundation to identify wetland loss

Global trends in wetland degradation and loss have created an urgency to monitor wetland extent, as well as track the distribution and causes of wetland loss. Satellite imagery can be used to monitor wetlands over time, but few efforts have attempted to distinguish anthropogenic wetland loss from climate-driven variability in wetland extent. We present an approach to concurrently track land c...

Modeling bird species richness for the southeastern United States (2001, 2006, and 2011)

These datasets are the inputs, script, and output of bird species richness modeling for the southeastern United States in the years 2001, 2006, and 2011 using general joint attribute modeling (GJAM). Inputs include environmental predictor variables for Breeding Bird Survey routes, bird counts from Breeding Bird Survey observations, and environmental predictor variables on a half-

Supply of and demand for wild pollinator habitat in the Southeast United States

Wild insect pollination has significant positive effects on pollinator-dependent crop production. To assess the spatial distribution of potential wild insect pollination, we mapped the supply of potential wild pollinator habitat (forest, grassland, wetland, and shrubland land cover types) and the demand for pollination (directly pollinator-dependent crops). A foraging travel

Supply of and demand for water purification of nonpoint source pollutants in the Southeast United States

Natural land cover can remove pollutants from runoff water by slowing water flow and physically trapping suspended particles. We identified natural land cover in the Southeast US potentially contributing to water purification due to its location in the flowpath between sources of nonpoint-source pollution and waterways.

Recreational birding in the Southeast United States

Total recreational birding activity (by state and year) estimated by the National Survey for Fishing, Hunting, and WIldlife-Associated Recreation was spatially distributed using birding observations reported through the eBird citizen science database and summarized by land cover type for each analysis year (2001, 2006, and 2011).

Total ecosystem carbon storage in the Southeast United States

Carbon storage by ecosystem type and protection status was derived from total ecosystem carbon estimates provided by Sleeter et al. 2018 and used to estimate terrestrial carbon storage in developed, forested, shrub/scrub, grassland/herbaceous, and agricultural land in the Southeast United States. It does not include estimates for wetland carbon storage.

Data release for Geologic Map of the Homestake Reservoir 7.5' quadrangle, Lake, Pitkin, and Eagle Counties, Colorado

The Homestake Reservoir 7.5' quadrangle lies at the northwestern end of the Upper Arkansas Valley, and headwaters of the Arkansas River, and the Roaring Fork, Fryingpan, and Eagle Rivers of the Colorado River system. The quadrangle lies within tectonic provinces of the 1.4 Ga Picuris Orogeny, the late Paleozoic Ancestral Rockies, Late Cretaceous-Paleocene Laramide orogeny, Oligo
