All Data

The collection of borehole geophysical logs and thermal imaging data was conducted by the U.S. Geological Survey South Atlantic Water Science Center in the vicinity of the Hemphill Road TCE National Priorities List Superfund site near Gastonia, North Carolina, during August 2014 through February 2015. In an effort to assist the U.S. Environmental Protection Agency in the development of a conceptua

The risks to wildlife and humans from uranium (U) mining to the Grand Canyon watershed are largely unknown. In addition to U, other co-occurring ore constituents contribute to risks to biological receptors depending on their toxicological profiles. This data was collected to characterize the pre-mining concentrations of total arsenic (As), cadmium (Cd), copper (Cu), lead (Pb), mercury (Hg), nicke

We illustrate the utility of expert elicitation, explicit recognition of uncertainty, and the value of information for directing management and research efforts for invasive species, using tegu lizards (Salvator merianae) in southern Florida as a case study. We posited a post-birth pulse, matrix model, which was parameterized using a 3-point process to elicit estimates of tegu demographic rates f

Between the years 2000 and 2016, scientists and technicians from the U.S. Geological Survey (USGS) Columbia Environmental Research Center (CERC) have collected over 400 field-days worth of acoustic Doppler current profiler (ADCP) measurements on the Missouri and Yellowstone Rivers, primarily for the purposes of assessing physical aquatic habitat for the pallid sturgeon. Scientists and technicians

Data for mercury concentrations in annual litterfall samples and associated litterfall mass will be released. The litterfall samples were collected at selected National Atmospheric Deposition Program sites in 2007-2009 and 2012-2014.

This point cloud was derived from low-altitude aerial images collected from an unmanned aerial system (UAS) flown in the Cape Cod National Seashore on 1 March, 2016. The objective of the project was to evaluate the quality and cost of mapping from UAS images. The point cloud contains 434,098,030 unclassifed and unedited geolocated points. The points have horizontal coordinates in NAD83(2011) UTM Z

Examination of food webs and trophic niches provide insight into organisms functional ecology, yet few studies have examined the trophodynamics within submarine canyons, where the interaction of morphology and oceanography influences food deposition. Stable isotope analysis and Bayesian ellipses documented deep-sea food web structure and trophic niches in Baltimore Canyon and the adjacent open slo

The current study was designed to provide critical information for resource managers (specifically the Bureau of Ocean Energy Management, henceforth BOEM, and the U.S. Fish and Wildlife Service, henceforth USFWS) about the spatial ecology, population status, and potential population threats to sea otters in Santa Barbara Channel, with particular reference to exposure to manmade structures and sour

The collection of borehole geophysical log was conducted by the U.S. Geological Survey South Atlantic Water Science Center in the vicinity of the Cristex Drum National Priorities List Superfund site near Oxford, North Carolina, during January and February 2016. In an effort to assist the U.S. Environmental Protection Agency in the development of a conceptual groundwater model for the assessment of

he data release consists of evapotranspiration measurements made at the USGS Starkey pasture climate station beginning January 1, 2010 and ending April 30, 2016. Annual ET rates corrected to a near-surface energy-budget for the 12 calendar years of record at this site (2004-2015) varied from 718 mm (2007) to 903 mm (2010). The eddy-covariance method was used, with high-frequency sensors installed

Diet contents of Deepwater Sculpin (Myoxocephalus thompsonii) were identified, enumerated, and measured to monitor the changes in the offshore benthic fish community within Lake Huron. Collections were made using a 21-m headrope with a 4.76mm square mesh cod-end with 10 minute contour trawl tows.. Deepwater Sculpin collected from the USGS fall forage (2003-2005 and 2010-2014) were counted and weig
