Science Datasets

The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Acoustic Doppler current profiler velocity data collected in the approach channel of Brandon Road Lock and Dam in 2015

Water velocities were measured in the Des Plaines River from approximately river mile 286 to river mile 284 on October 19–21, 2015 using Teledyne Rio Grande 1200 kHz acoustic Doppler current profilers (ADCP). The data were georeferenced with differential GPS receivers with submeter accuracy. These velocity data were collected in support of the US Army Corps of Engineers Great Lakes...

Digital elevation models (DEMs) of the Elwha River delta, Washington, February 2016

This part of the data release presents a digital elevation model (DEM) derived from bathymetry and topography data of the Elwha River delta collected in February 2016. Two dams on the Elwha River, Washington State, USA trapped over 20 million m3 of sediment, reducing downstream sediment fluxes and contributing to erosion of the river's coastal delta. The removal of the Elwha and Glines Canyon...

Photographs from the Blue Ridge Parkway in Virginia (Snowden region)

This dataset contains photographs keyed to station points along the Blue Ridge Parkway in Virginia. Photographs are titled and arranged by 7.5-minute quadrangle, and station points are located in the "Detailed geologic mapping geodatabase for the Blue Ridge Parkway in Virginia." The first part of the photograph's filename corresponds to the FieldID attribute of the PhotoPoints entity in the...

WDM file, Meteorological Database, Argonne National Laboratory, Illinois, January 1, 1948 - September 30, 2015

ARGN15.WDM contains nine data sets: air temperature in degrees Fahrenheit (DSN 400), dewpoint temperature in degrees Fahrenheit (DSN 500), wind speed in miles per hour (DSN 300), solar radiation in Langleys (DSN 600), computed potential evapotranspiration in thousandths of an inch (DSN 200), and four data-source flag series for air temperature (DSN 410), dewpoint temperature (DSN 510...

Data in support of manuscript "Evaluation of Chemical Control for Invasive Crayfish at a Warmwater 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...

Gust Erosion Chamber Data, Yolo Bypass, CA (2015-16)

A Gust erosion chamber was used to apply horizontal shear stress to sediment cores obtained at selected locations within the Yolo Bypass near Sacramento, California. The locations correspond to different land uses; two cores were taken at each site. The shear stress was increased in stepwise fashion, and turbidity of the effluent monitored. From this, two quantities are calculated: 1) critical...

Borehole Nuclear Magnetic Resonance Data; Alaska, 2014

Fire can be a significant driver of permafrost change in boreal landscapes, altering the availability of soil carbon and nutrients that have important implications for future climate and ecological succession. However, not all landscapes are equally susceptible to fire-induced change. As fire frequency is expected to increase in the high latitudes, methods to understand the vulnerability and...

2-meter Swath interferometric backscatter data collected in 2014 by the U.S. Geological Survey along the Delmarva Peninsula, MD and VA (8-bit GeoTIFF, UTM Zone 18N, WGS 84)

The Delmarva Peninsula is a 220-kilometer-long headland, spit, and barrier island complex that was significantly affected by Hurricane Sandy. A U.S. Geological Survey cruise was conducted in the summer of 2014 to map the inner continental shelf of the Delmarva Peninsula using geophysical and sampling techniques to define the geologic framework that governs coastal system evolution at storm-...

Bathymetry and backscatter from 2013 interferometric swath bathymetry systems survey of Columbia River Mouth, Oregon and Washington

High-resolution swath bathymetry and backscatter were collected in the mouth of the Columbia River (MCR) as part of the Office of Naval Research (ONR) funded River and Inlet Dynamics Experiment in 2013. The goal of the U.S. Geological Survey’s component of the research was to evaluate the various hydrodynamic and sediment transport processes in the Columbia River estuary entrance using

Ozarkaquifer_2015waterlevelalt_contours

The regional Ozark aquifer potentiometric-surface map shows the altitude at which the water level would have risen in tightly cased wells and represents conditions during the period from November 2014 through January 2015. Water levels were measured during this period to ensure that wells had adequate time to recover from previous summer pumping and prior to the start of the 2015 summer...

This dataset shows the altitude at which the water level would have risen in tightly cased wells and represents conditions during the period from November 2014 through January 2015. Water levels were measured during this period to ensure that wells had adequate time to recover from previous summer pumping and prior to the start of the 2015 summer pumping season. Groundwater-level data from 178...

Evapotranspiration in the Upper Klamath Basin for the 2013 Growing Season (April - October)

The evapotranspiration (ET) datasets were created under contract for this study by the University of Idaho. A high-resolution remote sensing technique known as Mapping Evapotranspiration at High Resolution and Internalized Calibration (METRIC) was used to create estimates of the spatial distribution of ET.
