title: Go to View Manage Corrosivity index and streamflow datasets used to evaluate trends in potentially corrosive source waters in the Nation's streams and rivers

description: Changes in water corrosivity from 84 river sites were investigated using long-term data sets. Corrosive waters, often having elevated chloride (Cl) concentrations, can lead to metal leaching and promote corrosion in water distribution systems. Two different indices, the Chloride-Sulfate Mass Ratio (CSMR) and the Larson Ratio (LR), are commonly used to indicate the potential to promote corrosion in water distribution systems, with high values indicating an increase in the potential to promote corrosion. Though changes in treatment approaches at drinking water facilities are known to affect the corrosion indices, there is little information regarding how changes in the ionic composition of source waters may affect the corrosion indices. As part of the National Water-Quality Assessment (NAWQA) project of the National Water-Quality Program, long-term water-quality data from multiple sites across the Conterminous United States have been used to analyze seasonal- and flow-related variability and trends in the CSMR and LR indices.

title: Purcell_Nanophyetus_Data_Release_2017

description: Dataset for the paper entitled 'Detection of Nanophyetus salmincola in water, snails and fish tissues by quantitative PCR' AbstractWe report the development and validation of two quantitative polymerase chain reaction (qPCR) assays to detect N. salmincola DNA in water samples and fish and snail tissues. Analytical and diagnostic validation demonstrated good sensitivity, specificity and repeatability of both qPCR assays. N. salmincola DNA copy number in kidney tissue was significantly correlated with metacercariae counts based on microscopy. Extraction methods were optimized for the sensitive qPCR detection of N. salmincola DNA in settled water samples. Artificially spiked samples suggested that the 1 cercaria / L threshold corresponded to an estimated log10 copies / L &gt; 6.0. Significant correlation of DNA copy number / L and microscopic counts indicated that the estimated qPCR copy number was a good predictor of the waterborne cercariae number. However, the detection of real-world samples below the estimated 1 cercaria / L threshold suggests that the assays may also detect other parasite life stages, non-intact cercariae or free DNA that settles with the debris. In summary, the qPCR assays reported here are suitable for identifying and quantifying all life stages of N. salmincola that occur in fish tissues, snail tissues and water.

title: Borehole geologic-unit top-surface altitude and aquifer-component test data for the Piney Point aquifer, Virginia from 2009 through 2015

description: This USGS data release contains (1) geologic-unit top-surface altitudes in boreholes and (2) aquifer-test time-series water-level drawdowns, recoveries, and supporting data from the Piney Point aquifer in Virginia from 2009 through 2015. Extents, compositions, configurations, and geologic relations of six geologic units that compose the Piney Point aquifer were determined from geologists logs of sediment core and cuttings, borehole geophysical logs, and drillers logs. The Piney Point aquifer is characterized to address information needs for water-resource management in the Virginia Coastal Plain. Information on the Piney Point aquifer can benefit water-resource management in siting production wells, predicting likely well yield, and anticipating water-level response to withdrawals.

title: The influence of local- and landscape-level factors on wetland breeding birds in the Prairie Pothole Region of North and South Dakota dataset

description: The data set consists of data collected in 1995, 1996, and 1997 in wetlands in the Prairie Pothole Region of North Dakota and South Dakota. The data were summarized and used in the analysis for a U.S. Geological Survey Open File Report entitled: The influence of local- and landscape-level factors on wetland breeding birds in the Prairie Pothole Region of North and South Dakota. The data consist of two data sets. A species data set includes the common names, scientific names (species and genus), and four-letter alpha codes for 133 bird species observed during the three-year study. The bird abundance data set includes the abundance of wetland birds by wetland class (temporary, seasonal, semipermanent, permanent, alkali), wetland type (natural or restored), and landowner group (private or federal). In conjunction with surveys of wetland birds, the following wetland variables also were recorded: wetland size, date (julian date), location (easting and northing), local-level habitat variables (percent coverage of open water, emergent vegetation, wet meadow, and shoreline/mudflat) and landscape-level habitat variables (number of wetlands and percent cover of grass and wetlands within 800 m of a wetland).

title: A standardized photographic guide to woody plant spring phenology

description: Measuring plant phenologyâ the timing of recurring life history events such as leafout and floweringâ sounds tantalizingly simple, but is complicated by the reality that different people often interpret the same event (e.g., budburst or leafout) differently. Researchers have worked to overcome this with a series of guides that explicitly describe each phenological event in great detail. One of the most widely-used scales is the BBCH (Biologische Bundesanstalt, Bundessortenamt und CHemische Industrie), which defines several principal growth stages (see Table 1) and breaks down each stage into events within stages (e.g., first leaves separated). Yet, even with clearly described stages aimed at standardizing measurements of the same events taken by different observers, there can still be variation in observersâ interpretation of events. Thus, photographs of each defined stage, for each species of interest, can help standardize observations further. Here we present a photographic guide to the BBCH stages of 31 woody species common to northeastern North American temperate forests.

title: A hybrid machine learning model to predict and visualize nitrate concentration throughout the Central Valley aquifer, California, USA

description: The ascii grids associated with this data release are model inputs representing the Central Valley aquifer, California, and predicted nitrate concentrations (as NO3-N, mg/L) at two depth zones associated with private and public drinking water supply wells, respectively, . The model input and prediction grids are bound by the alluvial bed boundary that defines the Central Valley. The prediction grids were produced with Boosted Regression Tree (BRT) modeling methods within a statistical modeling framework using the statistical modeling software R (R Core Team, https://www.r-project.org/) and linear interpolation within Oasis Montaj software (Geosoft, version 9.0.2). The response variable was a set of nitrate concentrations in wells located within the Central Valley. We compiled the database of well nitrate measurements from private supply and public supply wells. Nitrate data came from two sources, the University of California at Davis (UC Davis) and the U.S. Geological Survey (USGS). Prior to statistical modeling, wells were spatially declustered using an equal area grid cell approach to reduce effects on the modeling of oversampling in areas of intensive agricultural land use. A total of 5170 wells were selected, 3508 of which were used for training and 1662 of which served as hold-out. A database of 25 predictor variables was used for the final BRT model and included well characteristics, land use, climate, soil properties, aquifer properties, depth to the water table, and estimates of nitrogen loading and groundwater age. Based on the gridded predictor variables and final model, nitrate predictions were made using the R raster package for 17 depth zones spaced throughout the aquifer (at 15.24, 30.48, 45.72, 60.96, 76.20, 91.44, 106.68, 121.92, 152.40, 182.88, 213.36, 243.84, 274.32, 304.80, 365.76, 426.72, and 487.68 m below ground surface) to create input layers for 3D mapping with Oasis Montaj software version 9.0.2 (GeoSoft, Inc., 2016). The nitrate prediction grids for each of the 17 depth zones were imported into the Oasis Montaj mapping environment software for 3D interpolation and visualization. Each grid was assigned a vertical thickness of 1 m and linear interpolation was used between each of the layers at a vertical resolution of 1 m to produce a complete representation of predicted nitrate concentration at depth throughout the Central Valley. For visualization purposes, nitrate predictions were extracted from the interpolated model at 54.86 m and at 121.92 m deep. These depths correspond to the average total depths of private and public wells for the training wells.

title: Replication Data for: Legislative Term Limits and Voter Turnout

description: According to reformers, legislative term limits should increase voter turnout by enhancing electoral competitiveness for legislative seats. However, this claim has been largely untested. The only existing study of the effect of legislative term limits on voter turnout, to date, finds that turnout in California did not increase after the imposition of term limits and may have decreased turnout. Yet, it is unclear whether this result generalizes to other states. This study employs a comparative state analysis of both aggregate turnout and district-level turnout rates in state legislative elections. We find that term limits significantly increase voting rates in state legislative elections.

title: Polar semidesert responses to long-term experimental warming and wetting, Thule, Northwest Greenland, 2018.

description: Dramatic increases in air temperature and precipitation are occurring in the High Arctic (70 °North), yet few studies have characterized the long-term responses of High Arctic ecosystems to the interactive effects of experimental warming and increased rain. Beginning in 2003, we applied a factorial summer warming and wetting experiment to a polar semidesert in northwest Greenland. Twenty-four 0.8 × 1 meter (m) experimental plots were established in three homogenous 70 m × 60 m areas. Plots were assigned to one of four different climate treatments: low-level warming (T1), high-level warming (T2), wetting (W), combined warming and wetting (T2W), and unmanipulated control (CTL). In summer 2018, we assessed several metrics of ecosystem structure and function, including plant cover, ecosystem carbon dioxide exchange, aboveground (leaf, stem) and belowground (litter, root, soil) carbon (C) and nitrogen (N) concentrations (%) and pools, as well as leaf and soil stable isotopes (δ13C and δ15N). Plant cover was assessed via the point-frame technique in 2003 and a digital "point-frame" in 2018. Ecosystem carbon dioxide exchange was assessed at 15-minute intervals with the chamber technique. To assess ecosystem structure we removed 20x20 centimeter turfs, dried them in the lab, and sorted and analyzed all components (i.e. stems, leaves, roots, soils) for C and N content. Leaf ecophysiology was assessed by clipping fully developed green leaves and analyzing their C, N, δ13C, and δ15N content.
