Data

Hydraulic testing and long-term monitoring have revealed significant overpressures and dramatic underpressures in Paleozoic shales and carbonates at the Bruce nuclear site on the eastern flank of the Michigan basin near Tiverton, Ontario. Although several lines of evidence from both laboratory and field studies suggest that a small amount of gas phase methane could be present in the shale, previo

This dataset consists of data collected at Badlands National Park (Interior, SD) that were used in the analysis in support of the article titled "Conserving all the pollinators: Variation in probability of pollen transport among insect taxa," which has been submitted to "Natural Areas Journal." Data collected between May-October, 2010 and 2011, and June-July 2012 included insects found in contact

In 2015-2016, the Ohio Division of Wildlife's undercover law enforcement purchased 1,200 grass carp (Ctenopharyngodon idella). Fish heads and eyeballs were sent overnight to U.S. Geological Survey Wetland and Aquatic Research Center for ploidy analysis. Field and laboratory standard operating procedures were established and followed. Fish lengths, fish weights, and eyeball weights were obtained fr

This Data Release provides hourly records of air and water temperature within 5 watersheds (Beaver Creek, Dry River, Mossy Creek, Passage Creek & Spout Run) in the Shenandoah Valley, VA in the summer of 2017. Data loggers were deployed and retrieved by Trout Unlimited personnel and volunteers.

Fish muscle tissue was analyzed for stable carbon and nitrogen isotope values (delta 13C and delta 15N) for two filter-feeding fishes native to China, silver carp (Hypophthalmichthys molitrix) and bighead carp (Hypophthalmichthys nobilis), and three native filter-feeding fish including bigmouth buffalo (Ictiobus cyprinellus), gizzard shad (Dorosoma cepedianum) and paddlefish (Polyodon spathula) in

This field activity is part of an effort to map geologic substrates of the Stellwagen Bank National Marine Sanctuary region off Boston, Massachusetts. The overall goal is to develop high-resolution (1-25,000-scale) interpretive maps, based on multibeam sonar data and seabed sampling, showing surficial geology and seabed sediment dynamics. The data collected in this study will aid research on the e

Data are contained in a comma-separated spreadsheet files (.csv) that describe vegetation characteristics of high- and low-use areas, nest tree sites, and individual nest trees used by western gray squirrels in the North Cascades as determined through live-trapping and radiotelemetry at two study sites: Stehekin, and the southern Methow Valley (Squaw Creek drainage), Washington. Squirrels were liv

Laboratory bioassays were conducted at Wayne State University in cooperation with USGS to determine if different species of cyanobacteria influence quagga mussel spawning and fertilization success. The data describes the algal cultures tested and their density/concentration, the number of individuals tested, and the spawning and fertilization success of quagga mussels exposed to the cyanobacteria

This U.S. Geological Survey (USGS) Data Release provides spatial water-quality data collected from John Redmond Reservoir in Coffey County, Kansas, on October 7, 2014, August 13, 2015, and April 25, 2016. All data are reported as raw measured values and are not rounded to USGS significant figures. Continuous water-quality monitors were used to measure water temperature, specific conductance, turbi

Woody encroachment and its effects on biodiversity in fens and grasslands has become an increasing concern in the conservation and management of plant communities. These data were collected to examine the effects of spring and summer prescribed burns on the plant community, cover, and structure in open and partially wooded fens at Seney National Wildlife Refuge, Michigan, using a before-after-cont

These data are nutrient concentrations of seven key forage-plant species in the ranges of three caribou herds, in northern Alaska. During the growing seasons of 2011-2014, we collected forage samples from 21 plots within the ranges of three caribou herds: Central Arctic Herd (2011-2013), Teshekpuk (2011-2013), Western Arctic (2013-2014). We also analyzed stable isotopes of carbon (13C), nitrogen (

These data were simulated using the SOILWAT model and were intended to characterize soil-water conditions at different ecological sites on the Southern Colorado Plateau. SOILWAT is a daily, site-specific, multi soil-layer, ecosystem water-balance model, driven by daily meteorology, as well as site soil texture and vegetation. The sites simulated correspond with Inventory and Monitoring (I&M) plots
