Dataset for Alaska Marine Fish Ecology Catalog

This collection of GIS layers was prepared for the report Alaska Arctic Marine Fish Ecology Catalog (U.S. Geological Survey Scientific Investigations Report 20165038). The layers display geographic distribution and sampling locations for Arctic marine fish species in the region of United States sectors of the Chukchi and Beaufort Seas. Certain diadromous species (for example, Pacific salmon, char,

Groundwater-Quality Data in the Tule-Tulare-Highlands-Kaweah Shallow Aquifer Study Unit, 2014-2015

The U.S. Geological Survey collected groundwater samples from 95 domestic wells in Tulare and Kings Counties, California in 2014-2015. The wells were sampled for the Tulare Shallow Aquifer Study Unit of the California State Water Resources Control Board Groundwater Ambient Monitoring and Assessment (GAMA) Program Priority Basin Projects assessment of the quality of groundwater resources used for d

Continuous monitoring and discrete water-quality data from groundwater wells in the Edwards aquifer, Texas, 201415

In cooperation with the San Antonio Water System, continuous and discrete water-quality data were collected from groundwater wells completed in the Edwards aquifer, Texas, 2014-2015. Discrete measurements of nitrate were made by using a nitrate sensor. Precipitation data from two sites in the National Oceanic and Atmospheric Administration Global Historical Climatology Network are included in the

Data for projected impacts of climate, urbanization, water management, and wetland restoration on waterbird habitat in California's Central Valley

The Central Valley of California is one of the most important regions for wintering waterbirds in North America despite extensive anthropogenic landscape modification and decline of historical wetlands there. Like many other mediterranean-climate ecosystems across the globe, the Central Valley has been subject to a burgeoning human population and expansion and intensification of agricultural and

Fatty Acid Signature Data of Chukchi Sea Polar Bears, 2008-2015

These data were collected to gain insights into the diet composition of Chukchi Sea polar bears. These data were collected to gain insights into the diet composition of Chukchi Sea polar bears.

Storm-Impact Scenario XBeach Model Inputs and Results

The XBeach model input and output of topography and bathymetry resulting from simulation of storm-impact scenarios at the Chandeleur Islands, LA, as described in USGS Open-File Report 2017-1009 (, are provided here. For further information regarding model input generation and visualization of model output topography and bathymetry refer to USGS Open-File Report

Evaluation of Chemical Control for Nonnative Crayfish at a Warm-water Fish Production Hatchery

Invasive crayfish are known to displace native crayfish species, alter aquatic habitat and community structure and function, and are serious pests for fish hatcheries. White River Crawfish (WRC; Procambarus acutus) were inadvertently introduced to a warm-water fish hatchery in Missouri, USA, possibly in an incoming fish shipment. We evaluated the use of chemical control for crayfish to ensure inco

Soil chemistry adjacent to roads treated with dust control products at Loess Bluffs National Wildlife Refuge

The health of soils along roadways is critical for maximizing habitat quality and minimizing negative ecological effects of roads. Adjacent to unpaved roads, soil chemistry may be altered by the deposition of dust, as well as by road treatment with dust suppressants or soil stabilizer products. If present in roadside soils, these product residues may be available to plants, terrestrial invertebrat

Supplemental data from: Hydraulic Characterization of Volcanic Rocks in Pahute Mesa Using an Integrated Analysis of 16 Multiple-Well Aquifer Tests, Nevada National Security Site, 200914

An improved understanding of groundwater flow and radionuclide migration downgradient from underground nuclear-testing areas at Pahute Mesa, Nevada National Security Site, requires accurate subsurface hydraulic characterization. To improve conceptual models of flow and transport in the complex hydrogeologic system beneath Pahute Mesa, the U.S. Geological Survey characterized bulk hydraulic propert

Targeted-Organic-Chemical Analysis Concentration Data for Surface-Water Samples Collected from 38 Stream Sites across the USA during 2012-2014

Surface-water organic contaminant concentration data for targeted chemical analysis of over 800 organic analytes in surface water from 38 stream site representing national gradients in urban and agricultural land use in the USA during 2012-14. ScienceBase Data Release for journal article entitled, "Targeted-Chemical Analysis Reveals Extensive Mixed-Organic-Contamination in USA Streams".

Bathymetry and capacity of Shawnee Reservoir, Oklahoma, 2016

The U.S. Geological Survey (USGS), in cooperation with the City of Shawnee, performed a detailed bathymetric survey of Shawnee Reservoir in 2016. Shawnee Reservoir (locally known as Shawnee Twin Lakes) is a manmade reservoir on South Deer Creek in Pottawatomie County, Oklahoma. The reservoir consists of two lakes connected by an equilibrium channel. The southern lake (Shawnee City Lake Number 1) w
