MODFLOW-NWT groundwater flow model used to evaluate groundwater availability with five forecast scenarios in the Northern High Plains Aquifer in Colorado, Kansas, Nebraska, South Dakota, and Wyoming MODFLOW-NWT groundwater flow model used to evaluate groundwater availability with five forecast scenarios in the Northern High Plains Aquifer in Colorado, Kansas, Nebraska, South Dakota, and Wyoming
This groundwater flow model used a previously developed three-dimensional groundwater flow model (https://doi.org/10.3133/sir20165153) was used to assess future groundwater availability in the Northern High Plains aquifer in Colorado, Kansas, Nebraska, South Dakota, and Wyoming. In this groundwater flow model, a modified version of a previously published soil-water-balance (SWB) model...
Re-Os Geochronologic Data for Porphyry Deposits in the Yukon-Tanana Upland, Eastern Alaska Re-Os Geochronologic Data for Porphyry Deposits in the Yukon-Tanana Upland, Eastern Alaska
Rhenium-osmium (Re-Os) geochronology of molybdenite provides a tool to directly date mineralizing events in hydrothermal systems. In the Yukon-Tanana upland of eastern Alaska, numerous molybdenite-bearing porphyry occurrences are recognized. The deposits are related to middle and Late Cretaceous granitoids (Kreiner and others, 2019; 2020). Some of the porphyry districts have multiple...
Simulation models for buffelgrass and alternative management strategies for Saguaro National Park, AZ Simulation models for buffelgrass and alternative management strategies for Saguaro National Park, AZ
This is a spatially-explicit state-and-transition simulation model of buffelgrass dynamics and alternative management actions in Saguaro National Park, AZ. Buffelgrass is an invasive grass spreading in the park. This work built on previous efforts that first developed a state and transition simulation model linked to FARSITE fire behavior model to describe buffelgrass dynamics in the...
Data and Code for Predicting Flood Damage Probability Across the Conterminous United States Data and Code for Predicting Flood Damage Probability Across the Conterminous United States
This data release contains the associated data described in the related primary publication, "Predicting Flood Damage Probability Across the Conterminous United States" (Collins et al. [2022], see Related External Resources section). Publicly available geospatial datasets and random forest algorithms were used to analyze the spatial distribution and underlying drivers of flood damage...
Status and Trends of North American Bats Summer Occupancy Analysis 2010-2019 Data Release Status and Trends of North American Bats Summer Occupancy Analysis 2010-2019 Data Release
This data release contains the results from the North American Bat Monitoring Program's report titled 'Status and Trends of North American Bats Summer Occupancy Analysis 2010-2019'. Specifically, these data include tabular data and geospatial data for the species-specific results related to the status and trends of 12 bat species at multiple spatial scales including: 10 km x 10 km grid...
Bridge-Site Study Data for Selected Highway Crossings in Mississippi, 2020 Bridge-Site Study Data for Selected Highway Crossings in Mississippi, 2020
The U.S. Geological Survey (USGS) works closely with the Mississippi Department of Transportation (MDOT) to provide information to be used by the MDOT for design of highway-drainage structures. MDOT spends millions of dollars annually for highway construction. Streamflow records, hydrologic analyses of basins, and hydraulic analyses of flooding potential at proposed highway crossings...
U-Pb and 40Ar/39Ar Geochronologic Data for Selected Rocks from the Western Alaska Range, Alaska U-Pb and 40Ar/39Ar Geochronologic Data for Selected Rocks from the Western Alaska Range, Alaska
This dataset includes four tables with isotopic data and ages for selected igneous bedrock samples collected in 2001 through 2003 from the Western Alaska Range, southcentral Alaska: (1) the concentration of uranium (U) and thorium (Th), ratios of multiple isotopes of lead (Pb) and U, and the age of multiple analytical aliquots, or fractions, of zircon for each sample; (2) the 40Ar/39Ar...
Data on Utah prairie dog body condition and reproductive success, Awapa Plateau, Utah, USA, 2013-2016 Data on Utah prairie dog body condition and reproductive success, Awapa Plateau, Utah, USA, 2013-2016
Data on body condition and reproduction of Utah prairie dogs at 5 colonies on the Awapa Plateau, Utah, USA, June-August 2013-2016. Utah prairie dogs were live-trapped and sampled on 5 colonies. We recorded the age (juvenile/adult) and mass (nearest 5 grams) of each prairie dog and marked its ears and body with metal tags and passive integrated transponders, respectively, for permanent
New Jersey StreamStats digital elevation, flow direction, and flow accumulation GIS data 2022 New Jersey StreamStats digital elevation, flow direction, and flow accumulation GIS data 2022
The U.S. Geological Survey (USGS), in cooperation with the New Jersey Department of Environmental Protection (NJDEP), prepared hydro-conditioned geographic information systems (GIS) data layers for use in the updated New Jersey StreamStats 2022 application (U.S. Geological Survey, 2022). This update features improvements in base-elevation resolution from 10 meters to 10 feet and stream...
Basin characteristics rasters for New Jersey StreamStats 2022 Basin characteristics rasters for New Jersey StreamStats 2022
The U.S. Geological Survey (USGS), in cooperation with the New Jersey Department of Environmental Protection (NJDEP), calculated several basin characteristics as part of the updated New Jersey StreamStats 2022 application (U.S. Geological Survey, 2022). These datasets are raster representations of various environmental, geological, and land use attributes within the New Jersey...
Sagebrush recovery analyzed with a dynamic reference approach in southwestern Wyoming, USA 1985-2018 Sagebrush recovery analyzed with a dynamic reference approach in southwestern Wyoming, USA 1985-2018
Identifying ecologically relevant reference sites is important for evaluating ecosystem recovery, but the relevance of references that are temporally static is unclear in the context of vast landscapes with disturbance and environmental contexts varying over space and time. This question is pertinent for landscapes dominated by sagebrush (Artemisia spp.) which face a suite of threats...
