Amphibian acoustic data from the Arizona 1, Pinenut, and Canyon breccia pipe uranium mines in Arizona.

USGS is currently conducting biological surveys associated with uranium mines on federal lands in Arizona. These surveys include determining the composition of the local amphibian community at Canyon, Arizona 1, and Pinenut mines near the Grand Canyon. To aid in determining the amphibian species present at each mine site, we used acoustic monitoring recorded with a SM3Song Meter (Wildlife Acoustic

Runtimes for Tests of Array-Processing Speed -- Factorial Tests Using C and C++ Under Windows and Linux

The dataset is provided as a .zip archive containing two .csv data files. These two data files contain the results of a series of timing runs made with a suite of 28 C test programs and 20 C++ test programs using three different computers and two operating systems (Windows and Linux). All 48 test programs carry out processing of two-dimensional arrays. One of the files, "C_CppTimeTestsAllRecords.c

Gridded bathymetry data of Clear Creek Reservoir, Chaffee County, Colorado, 2016

To better characterize the water supply capacity of Clear Creek Reservoir, Chaffee County, Colorado, the U.S. Geological Survey, in cooperation with the Pueblo Board of Water Works and Colorado Mountain College, carried out a bathymetry survey of Clear Creek Reservoir. The bathymetry data of the reservoir is presented here in a 1-foot grid. The bathymetry survey was carried out June 69, 2016, usin

Dynamic Parameter, Water-Use, Stream and Lake Flow Routing, and Two Summary Output Modules and Updates to Surface-Depression Storage Simulation and Initial Conditions Specification Options for the Precipitation-Runoff Modeling System (PRMS)

This data release documents seven enhancements to the U.S. Geological Survey (USGS) Precipitation-Runoff Modeling System (PRMS) hydrologic simulation code: two time-series input options, two new output options, and three updates of existing capabilities. The enhancements are (1) new dynamic parameter module, (2) new water-use module, (3) new Hydrologic Response Unit (HRU) summary output module, (4

San Francisco Bay Delta Bathymetric/Topographic digital elevation model (DEM) - 2016 SF Bay Delta DEM 10-m

A high-resolution (10-meter per pixel) digital elevation model (DEM) was created for the Sacramento-San Joaquin Delta using both bathymetry and topography data. This DEM is the result of collaborative efforts of the U.S. Geological Survey (USGS) and the California Department of Water Resources (DWR). The base of the DEM is from a 10-m DEM released in 2004 and updated in 2005 (Foxgrover and others,

Elevation Data Collected in 2010 from Sabine National Wildlife Refuge, Louisiana

This data release serves as an archive of elevation data collected in August 2010 from Sabine National Wildlife Refuge (SNWR), Louisiana. Point (xyz) elevations were collected from historically formed open-water bodies and the surrounding emergent marsh using a combination of stop-and-go (semi-kinematic) and kinematic differential Global Positioning System (DGPS) surveying techniques. These data w

Nebraska Natural Resources Districts Wells on Groundwater Watch

Groundwater well networks for Natural Resources Districts in Nebraska. Real-time, continuous, and periodic data are available.

Concentrations of Bioactive Organic Contaminants in Water and Sediment and Rates of Contaminant Biodegradation in Sediment at Congaree National Park, USA 2013-15

Data release including concentrations of bioactive organic contaminants in water and sediment and biodegradation rates of select model contaminants in sediment from Congaree National Park during 2013-15. Chemical analyses for targeted organic analytes include, human-use pharmaceuticals, degradates and metabolites and hormones and organic wastewater indicator compounds. Samples were collected betwe

Analysis of the effect of Hurricane Sandy on New Jersey Atlantic coastal marshes based on landsat thematic mapper and operational land imager data: 2000-2015

This USGS Data Release represents geospatial data sets that were created for the analysis of the effect of Hurricane Sandy on New Jersey Atlantic Coastal Marshes. The following listed image products were generated: 1) Fifteen marsh surface condition index (MSCI) data sets were calculated from yearly summer collections of ETM+ image data from 2000 to 2015. Three classes described the results of

Volcanic Gas Measurements at Mount Cleveland, 14-15 August 2015

Helicopter-based, upward-looking differential optical absorption spectroscopy (DOAS) measurements of scattered solar ultraviolet radiation and Multi-Component Gas Analyzer System (Multi-GAS) measurements of trace gas concentrations were made while traversing beneath and through the gas plume emitted from Mount Cleveland volcano on 14-15 August, 2016. Radiance spectra and gas compositions were reco

2017 One-Year Seismic Hazard Forecast for the Central and Eastern United States from Induced and Natural Earthquakes

We produced a one-year 2017 seismic hazard forecast for the central and eastern United States from induced and natural earthquakes that replaces the one-year 2016 forecast, and evaluated the 2016 seismic hazard forecast to improve future assessments. The 2016 forecast indicated high seismic hazard (greater than 1% probability of damaging ground shaking in 1 year) in portions of Oklahoma/Kansas, th

Earthquake catalogs for the 2017 Central and Eastern U.S. short-term seismic hazard model

The U. S. Geological Survey (USGS) makes long-term seismic hazard forecasts that are used in building codes. The hazard models usually consider only natural seismicity; non-tectonic (man-made) earthquakes are excluded because they are transitory or too small. In the past decade, however, thousands of earthquakes related to underground fluid injection have occurred in the central and eastern U.S. (
