DNA Microsatellite and Sex Identification Marker Screening for Mexican Spotted Owl (Strix occidentalis lucida)
Two tables of data are included in this data release. The first table provides screening results for 32 previously described and/or published microsatellites and 1 sexing marker, primer redesigns for use in Mexican Spotted Owls in this data release, and size of markers in Mexican Spotted Owls. The second table provides microsatellite and sexing marker results for 10 tissue and 98 feather samples f
Data on Models to Describe Groundwater Levels and Stream Stage near the Herring River, Wellfleet, Cape Cod, Massachusetts, 2017-2022
Groundwater and estuary water levels near Mill Creek and the Herring River in Wellfleet, Massachusetts, were measured from June 2017 to August 2022. The data contained in these datasets consist of tables of updated statistics provided in the original work by Mullaney and others (2020, Appendix 2) and associated data release by Mullaney and Barclay (2020). The data include summary tables of water-l
Water-Quality Data for Discrete Samples and Continuous Monitoring on the Merrimack River, Massachusetts, June to September 2020
This data release includes water-quality data collected at up to thirteen locations along the Merrimack River and Merrimack River Estuary in Massachusetts. In this study, conducted by the U.S. Geological Survey (USGS) in cooperation with the Massachusetts Department of Environmental Protection, discrete samples were collected, and continuous monitoring was completed from June to September 2020. Th
PIT Tags Encountered by Klamath Falls Field Station Equipment in the Upper Klamath Basin 1993-2023 (ver. 2.0, August 2023)
Data were collected as part of a long-term capture-recapture program to assess the status and dynamics of populations of two long-lived, federally endangered catostomids in Upper Klamath Lake, Oregon and Clear Lake Reservoir, California. Lost River suckers (LRS; Deltistes luxatus) and shortnose suckers (SNS; Chasmistes brevirostris) have been captured and tagged with passive integrated transponder
U.S. Geological Survey Precipitation Chemistry Quality Assurance Project Data 2021 – 2022
The National Atmospheric Deposition Program/National Trends Network (NADP/NTN) was initiated in 1978 by the Association of State Agricultural Experiment Stations to monitor long-term atmospheric chemistry and the effects pollutants have on aquatic and terrestrial systems. As of fall 2023, precipitation was being collected at approximately 260 NTN sites in the United States, including Puerto Rico a
Tree-ring widths of Picea engelmannii at Andrews Meadow, Rocky Mountain National Park
Andrews Meadow in the Loch Vale watershed, Rocky Mountain National Park. Sample Collection: Englemann spruce (Picea engelmannii) living on slopes surrounding and at the edge of Andrews meadow (Latitude 40˚ 17’ 24” N, Longitude 105˚ 40’ 01” W NAD83). At the time of collection, the climate-sensitive upland P. engelmannii trees were growing on well-drained slopes above the meadow. Seventeen trees, tw
Digital database of structure contour and isopach maps of multiple subsurface units, Michigan and Illinois Basins, USA
This digital data release presents contour data from multiple subsurface geologic horizons as presented in previously published summaries of the regional subsurface configuration of the Michigan and Illinois Basins. The original maps that served as the source of the digital data within this geodatabase are from the Geological Society of America’s Decade of North American Geology project series, “T
Central Alaska Cosmogenic Isotope Burial Age Data Collected 2020-2022
This data release includes three tables containing cosmogenic beryllium-10 and aluminum-26 concentrations and related data from samples collected at four sites in central Alaska in 2020, prepared in 2022 at the University of Vermont (UVM), and measured at the Purdue Rare Isotope Measurement lab (PRIME) in 2022. The file "geology_siteLocations_centralAK_bender.csv" contains site locations in the NA
Estimation of hydraulic properties in the Ogallala aquifer near Happy, Texas from slug test results at the North East 2nd Street Superfund site, U.S. Geological Survey data release
The North East 2nd Street Superfund site in Happy, Texas, overlies a groundwater plume of primarily carbon tetrachloride (CT) that is contained within an upper transmissive zone (EA Engineering, Science, and Technology, Inc., 2019) of the Ogallala aquifer. The Ogallala aquifer is contained at the site in Tertiary-age sediments of the Ogallala Formation, which are described by Nordstrom and Fallin
Tables and associated data for effects of impoundments on selected flood-frequency and daily mean streamflow characteristics in Georgia, South Carolina, and North Carolina
The U.S. Geological Survey (USGS) has a long history of working cooperatively with the South Carolina Department of Transportation to develop methods for estimating the magnitude and frequency of floods for rural and urban basins that have minimal to no regulation or tidal influence. As part of those previous investigations, flood-frequency estimates have been generated at selected regulated strea
Geomorphic variables for classification of the Upper Missouri River, Montana and North Dakota
This dataset consists of seven geomorphic variables attributed to standard river mile address points at 0.1 mile (160 m) intervals between Fort Peck Dam and the headwaters of Lake Sakakawea. The data illustrate the geomorphic variation in this 300-km segment of the Upper Missouri River and are indicative of channel complexity, thought to be an important influence on dispersal and retention of larv
Data on the detection of Epioblasma capsaeformis using a designed environmental DNA (eDNA) survey upstream and downstream of known populations in the Clinch River, Tennessee (2019 to 2021)
Data describe a designed environmental DNA (eDNA) survey for the detection of oyster mussel (Epioblasma capsaeformis) from field collected water samples. Parameters described include the limit of detection and limit of quantification of the assay; a list of freshwater mussel species tissue samples that were used to test specificity of the assay; and field collected water samples that were tested t
