Field and laboratory data collected for fishes sampled by boat electrofishing in the Sacramento-San Joaquin delta, CA. This data release includes all measured environmental parameters, body composition analyses, otoliths, and fish taxa included in the analysis.
Sample collection information and whole genome data for Greater and Gunnison Sage-grouse range generated in the Molecular Ecology Lab during 2015-2018 Sample collection information and whole genome data for Greater and Gunnison Sage-grouse range generated in the Molecular Ecology Lab during 2015-2018
This dataset contains sample collection information for whole genome sequences of Gunnison and Greater Sage-grouse. These data were collected in order to examine patterns of adaptive genetic variation in Greater and Gunnison Sage-grouse. The data is archived in GenBank at the following URL https://www.ncbi.nlm.nih.gov/bioproject/531321.
Genetic data and genetic network attributes for rangewide Greater Sage-grouse network constructed in 2018 (ver. 2.0, December 2022) Genetic data and genetic network attributes for rangewide Greater Sage-grouse network constructed in 2018 (ver. 2.0, December 2022)
Genetic networks can characterize complex genetic relationships among groups of individuals, which can be used to rank nodes most important to the overall connectivity of the system. Ranking allows scarce resources to be guided towards nodes integral to connectivity. The greater sage-grouse (Centrocercus urophasianus) is a species of conservation concern that breeds on spatially discrete...
Data maps of predicted raven density and areas of potential impact to nesting sage-grouse within sagebrush ecosystems of the North American Great Basin Data maps of predicted raven density and areas of potential impact to nesting sage-grouse within sagebrush ecosystems of the North American Great Basin
These data represent predicted common raven (Corvus corax) density (ravens/square-km) derived from random forest models given field site unit-specific estimates of raven density that were obtained from hierarchical distance sampling models at 43 field site units within the Great Basin region, USA. Fifteen landscape-level predictors summarizing climate, vegetation, topography and...
Success Dam Spillway seismic refraction survey, Porterville, California, December 2018 and July 2019 Success Dam Spillway seismic refraction survey, Porterville, California, December 2018 and July 2019
Compressional- (P-) wave seismic refraction data were acquired in December 2018 and July 2019 along fourteen profiles within the spillway of Success Dam in Porterville, California. A new concrete ogee weir is planned for construction within the existing spillway, and the P-wave seismic velocity models will be used to inform further geotechnical investigations, including siting new...
U-Pb Isotopic Data and Ages of Detrital Zircon Grains, Whole Rock Major and Trace-element Geochemistry, and Whole Rock Isotopic Data from Selected Rocks from the Western Alaska Range, Medfra area, and Livengood area, Alaska U-Pb Isotopic Data and Ages of Detrital Zircon Grains, Whole Rock Major and Trace-element Geochemistry, and Whole Rock Isotopic Data from Selected Rocks from the Western Alaska Range, Medfra area, and Livengood area, Alaska
This data release contains 3 datasets, U-Pb isotopic data and associated ages of detrital zircon grains for 27 sedimentary rocks, whole rock major and trace-element geochemistry for 15 igneous or phosphatic rock samples, and whole rock Sr, Nd, and Pb isotopic data for 6 igneous rock samples. The samples were collected from multiple localities across Alaska as part of geological mapping...
Flood regions and annual exceedance probability flows for Alabama streams, data through 2015 Flood regions and annual exceedance probability flows for Alabama streams, data through 2015
To improve flood-frequency estimates at rural streams in Alabama, annual exceedance probability (AEP) flows at gaged streams in Alabama and regional-regression equations, used to estimate AEP flows for ungaged streams in Alabama, were developed using current geospatial data, additional statistical methods, and annual peak-flow data through the 2015 water year. The regional-regression...
Aquifer test data for multiple-well monitoring site LHSP, Kern County, California Aquifer test data for multiple-well monitoring site LHSP, Kern County, California
To determine aquifer characteristics, pneumatic slug tests were performed on selected zones and aquifers at a monitoring site near the Lost Hills oil field in the Southern San Joaquin Valley in Kern County. On May 30th and 31st, 2018, pneumatic slug tests were performed at five monitoring wells located at the multiple-well groundwater-monitoring site LHSP (26S/21E-07J1 through ?J5) near...
Shore Proximal Sediment Deposition, Elevation, Turbidity, and Water Level Data for Four Sites in the Coastal Marsh at Grand Bay National Estuarine Research Reserve, Mississippi, From October 2016 Through October 2017 Shore Proximal Sediment Deposition, Elevation, Turbidity, and Water Level Data for Four Sites in the Coastal Marsh at Grand Bay National Estuarine Research Reserve, Mississippi, From October 2016 Through October 2017
To understand sediment deposition in marsh environments, scientists from the U.S. Geological Survey, St. Petersburg Coastal and Marine Science Center (USGS-SPCMSC) selected four study sites in the Grand Bay National Estuarine Research Reserve, Mississippi (GNDNERR). Each site consisted of four plots located along a transect perpendicular to the marsh-estuary shoreline at 5-meter (m)...
Lotic vs. Lentic Water: a U.S. national 30-meter raster classification of water areas by velocity Lotic vs. Lentic Water: a U.S. national 30-meter raster classification of water areas by velocity
This dataset consists of a national 30-meter raster which classifies pixels representing water from the National Land Cover Database 2016 (NLCD 2016) according to their estimated velocity regime. At the broadest classification, the data are mapped into two groups: "Lentic", representing water bodies such as lakes, ponds, oceans, and bays, and "Lotic", representing flowing water, such as...
Data Release for Toward ecosystem accounts for Rwanda: Tracking 25 years of change in ecosystem service potential and flows Data Release for Toward ecosystem accounts for Rwanda: Tracking 25 years of change in ecosystem service potential and flows
Ecosystem accounts link national-scale environmental and economic trends, offering an internationally standardized approach to tracking sustainability. We compile ecosystem accounts for Rwanda over a 25-year period, and demonstrate that despite strong economic growth, social development, and high-level commitment to environmental goals, ecosystem services fundamental to Rwanda's well...
MODFLOW-2005 model used to Simulate the Evolution of Fluid Underpressures in the Great Plains, by Incorporation of Tectonic Uplift and Tilting MODFLOW-2005 model used to Simulate the Evolution of Fluid Underpressures in the Great Plains, by Incorporation of Tectonic Uplift and Tilting
A sequence of nine groundwater models was created to study whether underpressures (subhydrostatic heads) in the Paleozoic units underlying the Great Plains of North America are a consequence of Cenozoic uplift of the area. Based on tectonostratigraphic data, we have incorporated into these nine models a cumulative uplift history with superimposed periods of deposition and erosion for the...
