Spatially-Explicit Predictive Maps of Greater Sage-Grouse Brood Selection Integrated with Brood Survival in Nevada and Northeastern California, USA Spatially-Explicit Predictive Maps of Greater Sage-Grouse Brood Selection Integrated with Brood Survival in Nevada and Northeastern California, USA
We used a hierarchical Bayesian modeling framework to estimate resource selection functions and survival for early and late brood-rearing stages of sage-grouse in relation to a broad suite of habitat characteristics evaluated at multiple spatial scales within the Great Basin from 2009 to 2019. Sage-grouse selected for greater perennial grass cover, higher relative elevations, and areas...
Ecological Data Mapper Ecological Data Mapper
This application was created to visualize and interact with the ecological data from the ongoing monitoring effort on two previously restored streams in Reston, Virginia - Snakeden Branch and The Glade. The “Reston monitoring program” includes the measurement of hydrologic, water-quality, and ecological data and evaluations of changes in these measurements over time. For more information...
Digital Database of the Previously Published Geologic and Structure Contour Map of the La Junta Quadrangle, Colorado and Kansas Digital Database of the Previously Published Geologic and Structure Contour Map of the La Junta Quadrangle, Colorado and Kansas
This digital dataset release of the La Junta, Colorado and Kansas quadrangle is composed of previously published elevation contours, structure contours on the limits of the Morrison, Dakota, and Purgatorie Formations, and geologic formational data. The digitizing of this map is to provide a more accessible dataset to be available for public usage. The original dataset was part of an...
Digital database of the previously published geologic map of the Scottsbluff 1° x 2° quadrangle, Nebraska and Colorado Digital database of the previously published geologic map of the Scottsbluff 1° x 2° quadrangle, Nebraska and Colorado
This data release contains a digital compilation of geologic data from the Scottsbluff 1° x 2° quadrangle of western Nebraska and northeastern Colorado, a region predominantly characterized by Quaternary and Tertiary sedimentary and extrusive igneous rocks. This geodatabase, digitized from published resources, includes the position of volcanic ash-bed localities, structural data of...
Mallnock, Wolfram Camp, and Andrew Curtis Scheelite and Wolframite U-Pb Isotope Data Mallnock, Wolfram Camp, and Andrew Curtis Scheelite and Wolframite U-Pb Isotope Data
Uranium and lead isotope ratios from (1) scheelite from ore deposits near Mallnock, Austria, (2) wolframite from the Wolfram Camp mine, Australia, and (3) scheelite from the Andrew Curtis mine near Los Angeles, California are provided in spreadsheet format. Data from four analysis sessions are included and separated according to both analysis data and mineral analyzed meaning 4...
Central Valley Hydrologic Model version 2 (CVHM2): Surface Water Network for Water Years 1922 - 2019 (ver. 2.1, June 2024) Central Valley Hydrologic Model version 2 (CVHM2): Surface Water Network for Water Years 1922 - 2019 (ver. 2.1, June 2024)
This digital dataset contains the monthly inflows and diversions to the surface-water network in the updated Central Valley Hydrologic Model (CVHM2) for water years 1922-2019. The surface-water network simulates the Central Valley’s complex conveyance network through the Streamflow Routing Package (SFR2) and the Farm-Process (FMP4) at 65 inflow locations with 271 stream segments and 13
Geomorphic Mapping for the lower Middle Fork Willamette River, Oregon in 2018 and 2020 Geomorphic Mapping for the lower Middle Fork Willamette River, Oregon in 2018 and 2020
Since 2008, large-scale restoration programs have been implemented along the Willamette River, Oregon, to address historical losses of floodplain habitats for native fish. For much of the Willamette River floodplain, direct enhancement of floodplain habitats through restoration activities is needed because the underlying hydrologic, geomorphic, and vegetation processes that historically...
Applying Simulated Treatments to Bat Populations Experiencing Severe White-nose Syndrome Mortality Applying Simulated Treatments to Bat Populations Experiencing Severe White-nose Syndrome Mortality
We developed a model allowing for the application of treatment strategies to bat populations at risk of severe mortality from WNS. The model allows the bat population to exist within a network of hibernacula and updates survival, reproduction, movement, treatment applications, and treatment related disturbance annually. For simplicity, the effects of WNS are experienced across all...
Probability of nitrate concentrations exceeding multiple thresholds in shallow groundwater, Mid-Atlantic Region of the United States Probability of nitrate concentrations exceeding multiple thresholds in shallow groundwater, Mid-Atlantic Region of the United States
This data release consists of rasters representing the probability of exceeding multiple thresholds of nitrate in shallow groundwater for the Mid-Atlantic region of the United States. Each raster represents the results from multiple spatial-probability models that were developed using U.S. Geological Survey water-quality data in conjunction with geographic data such as land cover...
Data from Decadal Change in Groundwater Quality Web Site, 1988-2021 Data from Decadal Change in Groundwater Quality Web Site, 1988-2021
Evaluating Decadal Changes in Groundwater Quality: Groundwater-quality data were collected from 5,000 wells between 1988-2001 (first decadal sampling event) by the National Water-Quality Assessment Project. Samples are collected in groups of 20-30 wells with similar characteristics called networks. About 1,500 of these wells in 67 networks were sampled again approximately 10 years later...
Central Valley Hydrologic Model version 2 (CVHM2): Model Setup Files Central Valley Hydrologic Model version 2 (CVHM2): Model Setup Files
The model setup of the updated Central Valley Hydrologic Model (CVHM2) is similar to the original Central Valley Hydrologic Model (CVHM). The differences in the model setup are described here as either model discretization, tidal influence, or drain flow. For model discretization, CVHM2 has 13 layers compared to 10 in CVHM. Tidal data for the San Francisco Bay and its influence on the...
Shapefiles of hydrogeologic unit extents and top-surface altitude contours used in the revised hydrogeologic framework for the Virginia Coastal Plain Southwest of the James River Shapefiles of hydrogeologic unit extents and top-surface altitude contours used in the revised hydrogeologic framework for the Virginia Coastal Plain Southwest of the James River
A revision to the hydrogeologic framework of the Virginia coastal plain southwest of the James River was developed by USGS during 2019-2021. This revision includes modifications to existing understanding of the groundwater system in Prince George, Surry, Sussex, Isle of Wight, and Southampton counties and the cities of Franklin and Suffolk in southeast Virginia. This USGS data release...
