Data

This dataset contains environmental tracer data from surface water and groundwater samples collected by the U.S. Geological Survey in Redwell Basin, an alpine watershed in the Elk Mountains near the town of Crested Butte, Colorado. The basin is underlain by interbedded shale and sandstone that have been variably hydrothermally altered and silicified by local magmatic intrusions. Samples...

Land plays a critical role in both economic and environmental accounting. As an asset, it occupies a unique position at the intersection of the System of National Accounts (SNA), the System of Environmental-Economic Accounting Central Framework (SEEA-CF), and (as a spatial unit) SEEA Experimental Ecosystem Accounting (SEEA-EEA), making land a natural starting point for developing natural...

This data release provides inputs needed to run the LANDIS PRO forest landscape model and the LINKAGES 3.0 ecosystem process model for the area burned by the Black Dragon Fire in northeast China in 1987, and simulation results that underlie figures and analysis in the accompanying publication. The data release includes the fire perimeter of Great Dragon Fire; input data for LINKAGES...

This data product includes two datasets acquired for the study of northern Yellowstone mule deer seasonal movement and survival patterns. One data set "Point Locations of Radio-collared female northern Yellowstone mule deer" provides details about the date and time of relocations of radio-collared female northern Yellowstone mule deer along with location coordinates. Habitat types with...

Water provides society with economic benefits that increasingly involve tradeoffs, making accounting for water quality, quantity, and their corresponding economic productivity more relevant in our interconnected world. In the past, physical and economic data about water have been fragmented, but integration is becoming more widely adopted internationally through application of the System...

We created a probabilistic classification model using the nonparametric machine learning technique 'Random Forests' for oil and gas development potential from low (0) to high (1) across the western US. The six predictor variables used in the model were: geophysical data showing aeromagnetic, isostatic gravity, and Bouguer gravity anomalies, geology, topography and bedrock depth. Our...

The data release presents observations of riparian vegetation, topography, and ground cover in two river reaches of the Upper Colorado River within a river segment extending 208 river kilometers (rkm), from near the Colorado/Utah border to the confluence of the Green River. Methods included field observations and analysis of the plant community five times over eight years in the fall of...

Nocturnal visual encounter survey data conducted by 29 searchers over 17 transects obtained during a Brown Treesnake rapid response deployment to island of Saipan in 2016. Surveys took place in the vicinity of the Saipan airport and Dandan village (ca. 15.127°N, 145.735°E) from 06 January to 13 March 2016, 6-7 nights/week but with a break in surveying from 26 January through 21 February...

The data set consists of 2 spreadsheets from Airsoft Electric Gun (AEG) trials on brown treesnakes. AEG snake wound data contains AEG results from guns equipped with 0.39 gram ammunition (plastic pellets ) that were fired at dead and live snakes from distances of 4, 8, and 12 m to measure tissue-penetration depth, and noted if (a) the pellet was lodged inside the peritoneal cavity, (b)...

One of the largest conventional oil reservoirs in the United States, the Permian Basin, is becoming one of the world?s largest continuous oil and gas producing reservoirs. Continuous, or horizontal well drilling techniques extract oil and gas by directionally drilling and hydraulically fracturing the surrounding reservoir rock. The continuous extraction of oil and gas using hydraulic...

This dataset contains apatite and zircon U-Th(He)data, 4He/3He thermochronologic data, and apatite fission-track data from the southern Stillwater Range, Nevada

This dataset contains argon-argon and U-Pb geochronologic data collected from igneous rocks in the Stillwater Range, Clan Alpine, and Desatoya Mountains, western Nevada, USA.
