Bathymetry, topography, and sediment grain size data from the Elwha River delta, Washington, January 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
Bathymetry, topography, and sediment grain size data from the Elwha River delta, Washington, July 2016
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
USGS National and Global Oil and Gas Assessment Project-Permian Basin Province, Val Verde Basin, Canyon Sandstones Assessment Units
The Assessment Unit is the fundamental unit used in the National Assessment Project for the assessment of undiscovered oil and gas resources. The Assessment Unit is defined within the context of the higher-level Total Petroleum System. The Assessment Unit is shown herein as a geographic boundary interpreted, defined, and mapped by the geologist responsible for the province and incorporates a set o
ATRIS Seafloor Images-West Turtle Shoal Patch Reef, Rawa Patch Reef, Dustan Rocks Patch Reef, and Thor Patch Reef, Florida, 2011
The U.S. Geological Survey St. Petersburg Coastal and Marine Science Center developed the Along-Track Reef Imaging System (ATRIS) in order to capture high-resolution, geo-located images of the seafloor. The images in this data release were collected September 29-30, 2011 at West Turtle Shoal, Rawa, Dustan Rocks, and Thor patch reefs near Marathon, Florida. The transects below show the path of imag
Input data and results of WRTDS models and seasonal rank-sum tests to determine trends in the quality of water in New Jersey streams, water years 1971-2011
This USGS data release represents the input data used to identify trends in New Jersey streams, water years 1971-2011 and the results of Weighted Regression on Time, Discharge, and Season (WRTDS) models and seasonal rank-sum tests. The data set consists of CSV tables and Excel workbooks of:
trends_InputData_NJ_1971_2011: Reviewed water-quality values and qualifiers at selected stream stations
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

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
