National 1-km resolution rasters of selected Census of Agriculture statistics allocated to land use for the period 1950-2012
This dataset consists of a series of rasters covering the conterminous United States. Each raster is a one kilometer (km) grid for 18 selected Census of Agriculture statistics mapped to land use pixels for the time period 1950 to 2012. A supplemental set of 9 statistics mapped at the entire county level are also provided as 1-km rasters. The rasters are posted as ArcGIS grids. The statistics repre
Microhabitat and Vegetation Selection by Giant Gartersnakes Associated with a Restored Marsh in California
Studies of habitat selection can reveal important patterns to guide habitat restoration and management for species of conservation concern. Giant gartersnakes (Thamnophis gigas) are endemic to the Central Valley of California, where more than 90% of their historic wetland habitat has been converted to agricultural and other uses. Information about the selection of habitats by individual giant gart
Global temperate drylands climate change vulnerability
Drylands cover 40% of the global terrestrial surface and provide important ecosystem services. While drylands as a whole are expected to increase in distribution and aridity in coming decades, temperature and precipitation forecasts vary by latitude and geographic region suggesting different trajectories for tropical, subtropical, and temperate drylands. Uncertainty in the future of tropical and s
Bathymetric survey of the Brandon Road Dam Spillway, Joliet, Illinois
Bathymetric survey data of the Brandon Road Dam spillway was collected on May 27 and May 28, 2015 by the US Geological Survey (USGS) using Trimble Real-Time Kinematic Global Positioning System (RTK-GPS) equipment. The base station was set up over a temporarily installed survey pin on both days. This pin was surveyed into existing NGS benchmarks within the Brandon Road Lock property. In wadeable se
Bathymetry, topography, and sediment grain-size data from the Elwha River delta, Washington, July 2015
Two dams on the Elwha River, Washington State, USA trapped over 20 million cubic meters of sediment, reducing downstream sediment fluxes and contributing to erosion of the river's coastal delta. The removal of the Elwha and Glines Canyon dams between 2011 and 2014 induced massive increases in river sediment supply and provided an unprecedented opportunity to examine the response of a delta system
GDGT and Alkenone Flux in the Northern Gulf of Mexico
This dataset is a weekly to bi-weekly resolution 4-year time series (2010-2014) of GDGT and alkenone flux in the northern Gulf of Mexico. The TEX86 and U indices are also included, which are sea surface temperature proxies based on the distribution of GDGTs and alkenones, respectively. For further information regarding data collection and/or processing methods refer to Richey and Tierney (2016).
Susceptibility and antibody response of the laboratory model zebra finch
The data set contains the results of experimental challenge of captive
zebra finches with an American crow isolate of West Nile virus. Data include infectivity, mortality,
viremia, oral shedding of virus, and serology for anti- WNV antibodies. Australian and Timor zebra
finches were used in this study and both are useful as a laboratory model of an avian species with
moderate susceptib
St. Joseph River at Elkhart, Indiana, Flood-Inundation HEC-RAS Model
Flood profiles were computed for the USGS streamgage 04101000, St. Joseph River at Elkhart, Ind., reach by means of a one-dimensional, step-backwater hydraulic modeling software developed by the U.S. Army Corps of Engineers. The hydraulic model was calibrated using the current stage-discharge rating at the USGS streamgage 04101000, St. Joseph River at Elkhart, Ind., and the documented high-water m
Thermoelectric power plant water withdrawals and associated attributes for three Federal datasets in the United States, 2010
This dataset combines three Federal datasets of thermoelectric, non-industrial, power plant water withdrawals and associated plant information for the United States in 2010, excluding Puerto Rico and the U.S. Virgin Islands. Historically, thermoelectric water withdrawal has been estimated by the Department of Energy's Energy Information Administration (EIA) through surveys of plant operator-report
USGS Measurements of Water Quality in San Francisco Bay (CA), 1969-2015 (ver. 4.0, March 2023)
The U.S. Geological Survey maintains a program of water-quality studies in San Francisco Bay (CA) that began in 1969. We plan a USGS Data Release to archive and make available all measurements made from 1969 through 2015. Water-quality constituents include salinity, temperature, light attenuation coefficient, and concentrations of chlorophyll-a, dissolved oxygen, suspended particulate matter, nitr
Fire Patterns among Ecological Zones in the California Desert, 1984-2013
The California desert occupies the southeastern 27 percent of California (11,028,300 ha, 110,283 km2 or 27,251,610 ac). It includes two ecoregional provinces comprised of five desert regions ("ecological sections"; Miles and Goudy 1997). The American Semi-Desert and Desert Province (warm deserts) includes the Mojave Desert, Sonoran Desert, and Colorado Desert sections in the southern 83 percent of
Mean tidal range in salt marsh units of Edwin B. Forsythe National Wildlife Refuge, New Jersey
This dataset displays the spatial variation mean tidal range (i.e. Mean Range of Tides, MN) in the Edwin B. Forsythe National Wildlife Refuge (EBFNWR), which spans over Great Bay, Little Egg Harbor, and Barnegat Bay in New Jersey, USA. MN was calculated as the difference in height between mean high water (MHW) and mean low water (MLW) using the VDatum (v3.5) software (http://vdatum.noaa.gov/). The
