This dataset provides the expected and determined concentrations of selected inorganic and organic analytes for spiked reagent-water samples (calibration standards and limit of quantitation standards) that were used to calculate detection limits by using the United States Environmental Protection Agency’s (USEPA) Method Detection Limit (MDL) version 1.11 or 2.0 procedures, ASTM International’s Within-Laboratory Critical Level standard procedure D7783-13, and, for five pharmaceutical compounds, by USEPA’s Lowest Concentration Minimum Reporting Level procedure. Also provided are determined concentration data for reagent-water laboratory blank samples, classified as either instrument blank or set blank samples, and...

This child data release includes RGB (red-green-blue) videos acquired from an Unmanned Aircraft System (UAS) during a tracer experiment performed on the Missouri River near Columbia, Missouri, on May 5, 2021. One of the primary goals of this tracer experiment was to assess the feasibility of inferring concentrations of a visible dye (Rhodamine WT) from various types of remotely sensed data in a large, highly turbid natural river channel. Previous research on remote sensing of tracer dye concentrations has focused on clear-flowing streams, but the Missouri River is much more turbid. As a result, the effect of the dye on the reflectance of the water could be obscured by the effects of suspended sediment on reflectance....

Statewide maps of the probability of exceeding a given concentration of either uranium (U) or radon (Rn) in New Hampshire groundwater (represented as statewide rasters) are the product of statistical analyses and are available here. The dependent variables in these statistical models were either 1) the natural log of Rn concentrations or 2) a dichotomous variable indicating the exceedance of 1 microgram per liter (μg/L) U in groundwater samples. In the case of U, a dichotomous variable was used because of the large number of measured samples below the detection limit. A boosted Regression Tree (BRT) model was selected for the U analysis with an exceedance probability of 1 ug/L because that was near the center of...

Nonstationary streamflow due to environmental and human-induced causes can affect water quality over time, yet these effects are poorly accounted for in water-quality trend models. This data release provides instream water-quality trends and estimates of two components of change, for sites across the Nation previously presented in Oelsner et al. (2017). We used previously calibrated Weighted Regressions on Time, Discharge, and Season (WRTDS) models published in De Cicco et al. (2017) to estimate instream water-quality trends and associated uncertainties with the generalized flow normalization procedure available in EGRET version 3.0 (Hirsch et al., 2018a) and EGRETci version 2.0 (Hirsch et al., 2018b). The procedure...

To support research on dispersion in river channels, a tracer dye experiment was performed on the Kootenai River in northern Idaho, September 25-27, 2017. This data release provides access to hyperspectral image acquired during the experiment and the supporting field-based measurements of reflectance and dye concentration are available through related data releases. The hyperspectral image data were acquired by Quantum Spatial Inc. (QSI) using the ITRES CASI 1500H imaging system deployed from a Cessna Caravan manned aircraft from a flying height of 1000 m above ground level. Initial geometric and radiometric data processing was performed by ITRES and yielded images with 0.5 m pixels for each of 48 spectral bands...

Governmental policy options in response to increasing concern over an emerging greenhouse warming are reviewed. These will reflect differing levels of pofitical concem as understanding on the future size and impacts of the greenhouse effect evolves. High levels of concem will place emphasis on the option of limiting C02 emissions by restricting fossil fuel use. This option requires emphasis on energy efficiency and changes in energy supply, with increased use of natural gas, nuclear power or renewable energy sources. The progressive industrialization of the LDCs with the consequent growth in energy demand, may put additional pressure on developed countries to take action on this policy option.

Field spectra were collected from the Kootenai River in northern Idaho during a tracer dye experiment on September 25, 2017, to assess the potential for inferring concentrations of Rhodamine WT dye from remotely sensed data. Reflectance measurements were made from a boat near the confluence with Ball Creek with the Kootenai River using an Analytical Spectral Devices FieldSpec3 spectroradiometer operated in reflectance mode. The Rhodamine WT dye concentration at each spectral measurement location was interpolated from field measurements of concentration obtained with a Turner Designs C3 submersible fluorometer (sonde) by pairing time stamps from the spectra with those from the sonde. This data release provides both...

Hyperspectral image data and field measurements of Rhodamine WT dye concentration were obtained during a tracer study conducted at the Korea Institute of Civil Engineering and Building Technology's River Experiment Center May 17-20, 2017, to support research on dispersion in river channels. The image data included in this data release were acquired using a Nano-Hyperspec (Headwall Photonics, Inc.) mounted on an Aerotestra ATNK09, a small multirotor unmanned aircraft system (UAS). The in situ concentration data were collected using electronic fluorometers (YSI 600-OMS sonde with 6130 Rhodamine WT sensor). Image time stamps were used to link concentration time series recorded by the sondes to specific pixels. The...

To support research on dispersion in river channels, a tracer dye experiment was performed on the Kootenai River in northern Idaho, September 25-27, 2017. This data release provides in situ field measurements of Rhodamine WT dye concentration acquired during the experiment. A pulse consisting of 72.57 kg (160 pounds) of KEYACID™ Rhodamine WT dye that was 20% Rhodamine by weight was introduced into the Kootenai River channel from a single release point at the Kootenai Tribal Fish Hatchery over a period of 90 seconds ending at 20:10:40 PDT on 9/26/2017, which is equivalent to 04:10:40 on 9/27/2017 UTC. Information on the timing and location of the dye release is available from the KootenaiDyeReleasePoints.kmz Google...

The HCA toolkit is a GIS tool designed to support regional wildlife habitat connectivity analyses by automating the process of identifying habitat concentration areas (HCAs). HCAs are areas on the landscape between which patterns of connectivity are evaluated. The habitat areas identified by this toolkit may be used as an input for Linkage Mapper to model connectivity between HCAs. We developed this tool to support the 2010 Washington Wildlife Habitat Connectivity Working Group (WHCWG) statewide connectivity analysis, and are making it public for use in other wildlife connectivity assessments. The toolkit is available for download in a zip file that includes a user guide ,demo data, and scripts.
