Water Availability Tool for Environmental Resources for the Commonwealth of Kentucky updated for 2019 Water Availability Tool for Environmental Resources for the Commonwealth of Kentucky updated for 2019
In 2009, the Kentucky Water Science Center completed the Water Availability Tool for Environmental Resources (WATER-KY), which provided the ability to simulate streamflow for the period 1980-2000. This model integrated TOPMODEL (Beven and Kirkby, 1979) for pervious portions of the landscape with simulation of flow generated from impervious surfaces (USDA, 1986). Associated products...
Geochemical data for waters, rocks, sediments and biofilms from Rio Tinto, Spain Geochemical data for waters, rocks, sediments and biofilms from Rio Tinto, Spain
Rio Tinto, Spain, is an example of a fluvial system strongly influenced by acid rock and acid mine drainage. During the spring of 2018 and 2019, samples of stream waters and mine waters, biofilms, sediments and rocks, were collected in the field by Aubrey Zerkle. These samples were analyzed for comprehensive geochemistry, including Cr isotope geochemistry, anions and cations...
Debris-flow and Flood Video Files, Chalk Cliffs, Colorado, USA, 2015 Debris-flow and Flood Video Files, Chalk Cliffs, Colorado, USA, 2015
Chalk Cliffs, located 8 miles southwest of Buena Vista, Colorado, is one of the most active debris-flow areas in the state (U.S. Geological Survey). Three stations were set up at Chalk Cliffs which are located sequentially along a channel draining the 0.3 km2 study area. These stations are equipped with rain gauges, laser distance meters, and data loggers to record rainfall and stage...
Data release for Evidence of glacial activity during MIS 4 in the Rocky Mountains, Colorado, USA Data release for Evidence of glacial activity during MIS 4 in the Rocky Mountains, Colorado, USA
The Ziegler Reservoir fossil site near Snowmass Village, Colorado (USA) provides a rare opportunity to examine environmental conditions in the Rocky Mountains during marine isotope stage (MIS) 4 (71-57 ka). Although recognized as a global-scale cold event, MIS 4 is typically absent from Rocky Mountain glacial chronologies because the geologic evidence was either covered or destroyed...
Public supply, self-supplied domestic, irrigation, and thermoelectric water-use data from 5-year compilation datasets from 1985 to 2015 used to assess data variability and uncertainty Public supply, self-supplied domestic, irrigation, and thermoelectric water-use data from 5-year compilation datasets from 1985 to 2015 used to assess data variability and uncertainty
The U.S. Geological Survey (USGS) National Water Use Program is responsible for compiling and disseminating the Nation's water-use data. Working in cooperation with local, State, and Federal agencies, the USGS has published an estimate of water use in the United States every 5 years, beginning in 1950. These 5-year compilations contain water-use estimates that are aggregated to the...
LAMP assay for detection of Asian fish tapeworm LAMP assay for detection of Asian fish tapeworm
Data are relative fluorescent units obtained from the FAM channel of a AmpliFire Isothermal Fluorometer (Agdia, Inc., Elkhart, USA) recorded every 10 sec during as isothermal (LAMP) amplification. The isothermal reaction is to detect the Asian fish tapeworm, Schyzocotyle acheilognathi [syn. Bothriocephalus]. Samples (column headers) are described in tabs and include 1) positive control...
Carcass weights, 28S rRNA alignment file and parasite sample vouchers collected from California tiger salamanders (Ambystoma californiense) CTS and Santa Cruz long-toed salamander (Ambystoma macrodactylum croceum) SCLT from Prospect or Ellicott Pond, on E Carcass weights, 28S rRNA alignment file and parasite sample vouchers collected from California tiger salamanders (Ambystoma californiense) CTS and Santa Cruz long-toed salamander (Ambystoma macrodactylum croceum) SCLT from Prospect or Ellicott Pond, on E
Animal identification number, weight in grams for carcasses of California tiger salamanders (Ambystoma californiense) CTS and Santa Cruz long-toed salamander (Ambystoma macrodactylum croceum) SCLT from Prospect or Ellicott Pond, on Ellicott Slough National Wildlife Refuge, California U.S.A. submitted to U.S. Geological Survey, National Wildlife Health Center (NWHC) for determination of...
Thin section images of drill core and hand samples from the Stillwater Mine area, Stillwater Complex, Montana Thin section images of drill core and hand samples from the Stillwater Mine area, Stillwater Complex, Montana
This dataset includes photographic images of thin sections created from hand samples and drill core from the Stillwater Complex, Montana, along with a shapefile representing the locations of the underground samples and drill hole collars. The samples were collected and core was drilled in order to define platinum-group element resources associated with the J-M Reef at the Stillwater Mine...
Land cover classifications and associated data from treatment areas enrolled in the Phragmites Adaptive Management Framework, 2018 Land cover classifications and associated data from treatment areas enrolled in the Phragmites Adaptive Management Framework, 2018
During 2018, uncrewed aerial vehicles (UAVs or 'drones') were used to collect spatially referenced aerial imagery from 20 management units (sites) enrolled in the Phragmites Adaptive Management Framework, a collective learning program developed by the Great Lakes Phragmites Collaborative. Management units were located in Michigan, Ohio, and Wisconsin (USA). Invasive Phragmites australis...
Data compilation for regional synthesis of chemical characteristics of groundwater used for domestic supply in north-east and north-central Pennsylvania Data compilation for regional synthesis of chemical characteristics of groundwater used for domestic supply in north-east and north-central Pennsylvania
Groundwater quality data for 472 domestic well-water samples were retrieved from the USGS National Water Information System (NWIS) database and combined with descriptive information on the sampled well locations. The NWIS data for a sample, collected on the selected date, were averaged into a single record (one per well), and rounded according to USGS protocols. For evaluation and...
National Geochemical Database on Ore Deposits: Legacy data National Geochemical Database on Ore Deposits: Legacy data
There is a growing demand for commodities (elements, compounds, minerals) used in today's advanced technologies. Critical minerals are usually found in ore deposits that are deemed vital to economic and national security. The National Geochemical Database on Ore Deposits: Legacy data (NGDOD) contains chemistry and geologic information for nearly 30,000 historic ore and ore-related rock...
Current use pesticides in larval amphibian tissues, amphibian pathogen and wetland sediment screening data from three northeastern National Wildlife Refuges, 2013-2014 Current use pesticides in larval amphibian tissues, amphibian pathogen and wetland sediment screening data from three northeastern National Wildlife Refuges, 2013-2014
The data include concentrations of current use pesticides in tissues of larval wood frog (Lithobates sylvaticus) and spotted salamander (Ambystoma maculatum) and the presence of ranavirus in wood frogs and spotted salamanders from three northeastern National Wildlife Refuges sampled in 2013 and 2014. The data also include estrogenicity, protein phosphatase 2A inhibition and a suite of 15...
