Data

A bathymetric survey of Nimrod Lake, Arkansas, was conducted in late April to mid-May, 2016, by the Lower Mississippi-Gulf Water Science Center (LMG WSC) of the U.S. Geological Survey (USGS) using methodologies for sonar surveys similar to those described by Wilson and Richards (2006) and Richards and Huizinga (2018). Point data from the bathymetric survey were merged with point data from an aeria

Groundwater withdrawal estimates from 1913-2010 for the Death Valley regional groundwater flow system (DVRFS) are compiled in a Microsoft Access database. This database updates two previously published databases (Moreo and others, 2003; Moreo and Justet, 2008). A total of about 38,000 acre-feet of groundwater was withdrawn from the DVRFS in 2010, of which 47 percent was used for irrigation, 22 per

These data sets present results for analyses of the fraction of total and organic carbon in samples of rock core collected from boreholes 83BR, 84BR, 85BR, 86BR, 87BR, 88BR, and 89BR in the Lockatong Formation (mudstone) underlying the former Naval Air Warfare Center, West Trenton, New Jersey.

Individual measurements of toxicity and water quality data used to calculate means reported in the associated publication. The objectives of the present study were to (1) refine test conditions for improving mussel survival and growth in a long-term feeding study, (2) evaluate chronic toxicity of NaCl and KCl to fatmucket under traditional test conditions outlined in ASTM (ASTM 2017) and the refin

These data represent a set of capture histories of rainbow trout (Oncorhynchus mykiss or RBT) captured in the Colorado River (CR) and(or) detected on the multiplexer array in the Little Colorado River (LCR). Capture trips to the Colorado River occurred in April 2012, July 2012, September 2012, January 2013, April 2013, July 2013, September 2013, January 2014, April 2014, July 2014, and September 2

Temperature loggers were placed on the ground (n=4) and hung in the air (n=2) near the upstream connection point of four Willamette River off-channel features (side channels and alcoves) to assess timing and discharge conditions when these four off-channel features were inundated at the upstream end with flow from the main channel. Temperature readings indicate that the upstream end of an off-chan

Water quality point measurements were collected by the U.S. Geological Survey along the lower Willamette River near the cities of Lake Oswego and Wilsonville, Oregon, as well as the lowest two kilometers of the Clackamas River, Molalla River, and Johnson Creek. These measurements were collected in the main channel and off-channel features on discreet dates from April through October of 2017. All m

The Delft3D model inputs and outputs of bed levels resulting from the simulations of proposed navigation channel deepening and widening in Mobile Harbor, Alabama, as described in USGS Open-File Report 2018-1123, are provided here. For further information regarding model input generation and visualization of model output elevations, refer to USGS Open-File Report 2018-1123.

In this study, we create and evaluate a protocol to estimate the density, which can be used to estimate the abundance of terrestrial sound-producing animals from single automatic sound recorders. The protocol uses cue rates from the target species as well as sampling conditions and an estimate of the distance of the individual to the recorder based on the power of the sound. We applied our protoco

Annual estimates of road salt application were developed for the conterminous United States for the calendar years 1992 through 2015. The final estimates (in pounds) were derived from several data sources, which include road density and proportion of developed land use, depth and spatial extent of long-term snowfall, and the production and distribution of salt sources by state. The extent is the c

These data were compiled for monitoring and analyzing the amount of windblown (aeolian) sediment at 100 cm height near Moab, UT. Big Springs Number Eight (BSNE) field aeolian passive sediment traps are summarized by location and time period in shapefiles. Shapefiles also include attributes used to analyze patterns in the aeolian transport. Three different BSNE shapefiles represent 1) a network of

These data are comprised of measurements of aluminum, iron, cobalt, nickel, copper, zinc, arsenic, selenium, molybdenum, silver, cadmium, thallium, lead, bismuth, thorium, uranium, and mercury in soil, vegetation, and small rodents. Gross alpha activity, gross beta activity, and radionuclide activities (isotopic U, isotopic Th) are also presented for vegetation and soil. Radioactivities for small
