Data for the Comparison of Computed Flow Through Manually Operated Water Control Structures Using Theoretical Versus Calibrated Coefficients Data for the Comparison of Computed Flow Through Manually Operated Water Control Structures Using Theoretical Versus Calibrated Coefficients
Discharge through 13 water control structures in Florida was calculated using theoretical equations and coefficients and compared to USGS-published discharge from October 1, 2007 to September 30, 2019. The two daily mean discharges were not compared for any values below 10 cubic feet per second or if (1) any alterations were made to the published discharge to account for factors such as...
Data for volatile organic compounds in groundwater used for public supply across the United States, 2013-19, and data for associated quality-control samples Data for volatile organic compounds in groundwater used for public supply across the United States, 2013-19, and data for associated quality-control samples
This data release includes tables and time-series plots of results for volatile organic compounds (VOCs) analyzed in samples of groundwater used for public supply that were collected by the USGS National Water-Quality Assessment (NAWQA) Project and the California State Water Resources Control Board’s Groundwater Ambient Monitoring and Assessment Program Priority Basin Project (GAMA-PBP)...
Data from a 2019 occupancy survey of alligator snapping turtles, Macrochelys temminckii, in south-central Louisiana Data from a 2019 occupancy survey of alligator snapping turtles, Macrochelys temminckii, in south-central Louisiana
This dataset contains data on trapping methodology, turtle captures, and environmental variables from a trapping effort targeting alligator snapping turtles (Macrochelys temminckii) in south-central Louisiana in 2019.
Data from a turtle trapping effort at a release site of head-started alligator snapping turtles, Macrochelys temminckii, in southwest Louisiana in 2018 Data from a turtle trapping effort at a release site of head-started alligator snapping turtles, Macrochelys temminckii, in southwest Louisiana in 2018
This dataset contains initial data from head-started alligator snapping turtles released by Louisiana Department of Wildlife and Fisheries (LDWF) from November 2015 to October 2016. In addition, it contains data from a five-day trapping effort at each of seven release sites by the United States Geological Survey (USGS) from late June to early October 2018. Trapping was completed using...
Data from a turtle trapping effort targeting alligator snapping turtles (Macrochelys temminckii) in the Atchafalaya Basin beginning in 2019 Data from a turtle trapping effort targeting alligator snapping turtles (Macrochelys temminckii) in the Atchafalaya Basin beginning in 2019
This dataset contains data from an ongoing trapping effort beginning in 2019 targeting alligator snapping turtles (Macrochelys temminckii) in the Atchafalaya Basin of south-central Louisiana.
Data from an investigation of turtle basking behavior in the Atchafalaya Basin of south-central Louisiana in 2021 Data from an investigation of turtle basking behavior in the Atchafalaya Basin of south-central Louisiana in 2021
The dataset is comprised of game camera photos taken at known turtle basking structures in the Atchafalaya Basin's Little Alabama Bayou in south-central Louisiana. There was a spring camera deployment in April 2021 and a fall camera deployment in October 2021. Three game cameras were used in each deployment and photos were taken every two minutes for seven days for each camera. The...
Data from Decadal Change in Groundwater Quality Web Site, 1988-2021 Data from Decadal Change in Groundwater Quality Web Site, 1988-2021
Evaluating Decadal Changes in Groundwater Quality: Groundwater-quality data were collected from 5,000 wells between 1988-2001 (first decadal sampling event) by the National Water-Quality Assessment Project. Samples are collected in groups of 20-30 wells with similar characteristics called networks. About 1,500 of these wells in 67 networks were sampled again approximately 10 years later...
Data from the article “An opportunistic survey reveals an unexpected coronavirus diversity hotspot in North America” Data from the article “An opportunistic survey reveals an unexpected coronavirus diversity hotspot in North America”
In summer 2020, SARS-CoV-2 was detected on mink farms in Utah. An interagency One Health response was initiated to assess the extent of the outbreak and included sampling animals from or near affected mink farms and testing them for SARS-CoV-2 and non-SARS coronaviruses. Among the 365 animals sampled, including domestic cats, mink, rodents, raccoons, and skunks, 261 (72%) of the animals...
Data from the assessment of sediment-retention ponds near Delta, Colorado, 2019 Data from the assessment of sediment-retention ponds near Delta, Colorado, 2019
In 2019, soil samples were collected at selected sediment-retention ponds in the Gunnison Gorge National Conservation Area, near Delta, Colorado. This dataset includes pond location, pond characteristics, soil-moisture data, soil-chemistry data, and geophysical data. Pond locations were surveyed using real-time kinematic Global Navigation Satellite Systems (RTK-GNSS) methods and...
Data from the development and testing of a multiparameter standard solution for fluorescent dissolved organic matter (fDOM) and algal fluorescence (fChl) (ver. 2.0, July 2022) Data from the development and testing of a multiparameter standard solution for fluorescent dissolved organic matter (fDOM) and algal fluorescence (fChl) (ver. 2.0, July 2022)
Optical sensors measuring fluorescence of non-biological sources (e.g., dissolved organic matter, wastewater, hydrocarbons, fluorescent dyes, etc.; hereafter referred to as fDOM) are increasingly used in water quality studies because they provide proxy measurements for a variety of contaminants and constituents of concern including metals, wastewater effluent, and DOM (measured in the...
