40Ar/39Ar data from the Janub Metamorphic Complex, Southern Jordan. U.S. Geological Survey Data Release

This data release includes 40Ar/39Ar collected at the U.S. Geological Survey for samples from the Janub Metamorphic Complex in Southern Jordan. Rock samples were collected by Hind Ghanem of the University of Jordan. Muscovite-rich microcores were drilled from a polished thick section of a deformed granitoid and analyzed by argon geochronology at the U.S. Geological Survey Bascom ARgon Dating (BARD) Laboratory in Reston, Virginia. The 40Ar/39Ar data constrain the timing of formation of the foliation defined by muscovite.

African fish mercury burden and isotopic composition from archived museum specimens

Fish collected for taxonomic and systematic purposes are often preserved and then archived in museum collections. Preserved fish are commonly first fixed in a formalin solution and then transferred to ethanol for long-term storage. The wet preservation method can potentially introduce mercury (Hg) contamination or unintentionally extract Hg from tissue. An experiment was designed to test the utility of museum preserved fishes in reconstructing spatiotemporal trends in methylmercury (MeHg) concentration and Hg stable isotope ratios, which is used to trace Hg sources to fishes.
Wet preserved fish specimens from the Congo River and river basins within Gabon were subsampled from archives at the  the Royal Museum of Africa (Belgium). The fish tissue was analyzed for Hg speciation and carbon and nitrogen isotopes.

USGS National Wildlife Health Center necropsy and contaminant results for bald and golden eagles collected in 8 States from January 1, 2014, through December 31, 2017 to determine cause of illness/death and lead, mercury, and anticoagulant rodenticide exposure

The U.S. Geological Survey National Wildlife Health Center (NWHC) measured environmental contaminants in bald eagles (Haliaeetus leucocephalus) and golden eagles (Aquila chrysaetos) to evaluate dietary exposure to lead, mercury, and anticoagulant rodenticides (AR), which was identified by U.S. Fish and Wildlife Service (USFWS) as a priority issue of concern for the Mountain Prairie Region 6. Carcasses of bald eagles (n = 172) and golden eagles (n = 142) collected from North and South Dakota, Montana, Wyoming, Colorado, Utah, Nebraska, and Kansas between 2014-2017 were assessed for cause of death and liver lead, mercury, and AR levels. Trauma, electrocution, and lead poisoning were the 3 leading causes of death, affecting 51%, 21%, and 20% of eagles, respectively. Trauma was the leading cause of death for both species, while lead poisoning was the second leading cause of death for bald eagles (31%) and was only diagnosed as the cause of death in 7% of golden eagles. Elevated lead levels within the range of subclinical or clinical poisoning (&gt;2 mg/kg wet weight) were present in 25% of eagles tested, including 36% of bald eagles and 11% of golden eagles. No association was detected between lead exposure and trauma, electrocution, or infectious disease. Mercury levels were considered high (&gt;80 mg per kilogram dry weight) for only 2% of bald eagles and no golden eagles. Brodifacoum was the most common AR detected, present in 56% of eagles, including 70% of bald eagles and 39% of golden eagles. However, death was not directly attributed to AR toxicosis in any case.

Common loon winter archival geolocator tag location data

Breeding common loons were obtained for the movement and foraging pattern study from lakes in central and northern Minnesota and Wisconsin, and the Upper Peninsula of Michigan.   Both adults of a territorial pair were fitted with archival geolocator tags (Model LAT 2500; 34.6 x 8.3 mm, 4.4 g; Lotek Wireless Inc.).  A combination of adhesive and plastic cable ties were used to affix the geolocator tag to a modified lock-on aluminum leg band.  Tags were programmed to collect daily location estimates for up to two years, tag temperature (0.02 oC accuracy, ≤ 0.05 oC resolution) at 30-min intervals, and pressure data (±1% accuracy, 0.05% resolution) at 20-sec intervals during daylight hours to document foraging patterns (dive profiles) while on the Great Lakes during fall migration and on the wintering grounds.  Data stored on geolocator tags were not transmitted, requiring that the marked loon be recaptured to recover the tag and download the data.  The geolocator tags could store data for several years before the devices needed to be downloaded.  Geolocator tag data collected over the previous year(s) were downloaded from tags using LAT Viewer Studio software (Lotek Wireless Inc.).  Geolocator tag location estimates were based on light-based geolocations using the template-fitting approach (Exstrom, 2004), in combination with tag temperature (sea surface temperature) and pressure (dive depth) data.  Template-fit error estimates were used to filter aberrant geolocation estimates.  Sea surface temperature (derived from NASA Moderate Resolution Imaging Spectroradiometer [MODIS] imagery) across North America inland lakes, Atlantic coastal waters, and the Gulf of Mexico, coupled with diving depth information were used to improve or obtain location estimates and timing of migration movements when light-based geolocation estimates were unreliable.

15: Streamwater load and yield estimates for 12 constituents in 13 watersheds in Gwinnett County, Georgia for water years 2003-2020

The dataset contains annual and model calibration period streamwater constituent load and yield estimates for 13 watersheds in Gwinnett County, Georgia for the water years 2003 to 2020. Loads and yields were estimated for 12 water-quality constituents: total suspended solids, suspended sediment concentration, total nitrogen, total nitrate plus nitrite, total phosphorus, dissolved phosphorus, total organic carbon, total calcium, total magnesium, total lead, total zinc, and total dissolved solids. The USGS LOADEST load estimation software, which employs a regression-model estimation approach, was used for constituents that had at least a minimal relation with the model explanatory variables, as indicated by concentration model R-square &gt;0.20. The Beale ratio estimator was used to estimate loads for constituents that had weak concentration-model relations, concentration model R-squares &lt;0.20. Loads and yields are provided for the 13 individual study watersheds and for the study watersheds area. The period of loads available varies by watershed depending upon when monitoring and constituent analysis started. Uncertainties in load and yield estimates that were calculated using LOADEST are provided as 95-percent confidence intervals of the estimates.

13: Models coefficients and statistics for regression models used to estimate streamwater loads for 12 water-quality constituents in 13 watersheds in Gwinnett County, Georgia for water years 2003-2020

The dataset contains model coefficients and statistics for the 488 regression models used to estimate streamwater constituent loads for 13 watersheds in Gwinnett County, Georgia for two calibration periods, water years 2003-2010 and 2010-2020. Model terms were selected from an 11-parameter equation, which was a function of discharge, base flow, season, turbidity, and time (trend), using a forward stepwise ordinary least squares regression approach. Model coefficients were fit using U.S. Geological Survey (USGS) LOADEST load estimation software. Models were fit both with and without turbidity explanatory variables for 12 water-quality constituents: total suspended solids, suspended sediment concentration, total nitrogen, total nitrate plus nitrite, total phosphorus, dissolved phosphorus, total organic carbon, total calcium, total magnesium, total lead, total zinc, and total dissolved solids. The dataset includes a summary of sample concentrations used to calibration the models (period of samples collected, number of concentrations, number of censored concentrations, and number of outliers removed), model coefficients, and selected model statistics (concentration and load model R-squares, estimated residual variance, serial correlation in the model residuals, and Turnbull-Weiss normality test statistic of residuals). Portable document format files of LOADEST output are provided for each model in a “zip” file that contain model diagnostic statistics and plots for evaluating model fits.

11: Streamwater sample constituent concentration outliers from 15 watersheds in Gwinnett County, Georgia for water years 2003-2020

This dataset contains a list of outlier sample concentrations identified for 17 water quality constituents from streamwater sample collected at 15 study watersheds in Gwinnett County, Georgia for water years 2003 to 2020. The 17 water quality constituents are: biochemical oxygen demand (BOD), chemical oxygen demand (COD), total suspended solids (TSS), suspended sediment concentration (SSC), total nitrogen (TN), total nitrate plus nitrite (NO3NO2), total ammonia plus organic nitrogen (TKN), dissolved ammonia (NH3), total phosphorus (TP), dissolved phosphorus (DP), total organic carbon (TOC), total calcium (Ca), total magnesium (Mg), total copper (TCu), total lead (TPb), total zinc (TZn), and total dissolved solids (TDS). 885 outlier concentrations were identified. Outliers were excluded from model calibration datasets used to estimate streamwater constituent loads for 12 of these constituents. Outlier concentrations were removed because they had a high influence on the model fits of the concentration relations, which could substantially affect model predictions. Identified outliers were also excluded from loads that were calculated using the Beale ratio estimator. Notes on reason(s) for considering a concentration as an outlier are included.

Public-supply and industrial water withdrawals from the Sparta aquifer by parish in Louisiana, 2020

Since 1975, annual water use for Louisiana has been published on a 5-year basis and is used for a variety of purposes. As the Sparta aquifer is a heavily used aquifer, is the sole source of groundwater for many parishes in Louisiana, and recent withdrawals have exceeded the Sparta’s natural recharge, a more frequent compilation of water usage for the Sparta aquifer in Louisiana is needed to inform State conservation groups and efforts, private and public entities, and to feed groundwater models.
This data release contains water withdrawn for public supply, thermoelectric, and industrial use from the Sparta aquifer in 2020, tabulated by parish and water-use category.  The estimated public-supply withdrawals in 2020 from the Sparta aquifer in Louisiana were 35 million gallons per day (Mgal/d) and industrial water was 22 Mgal/d, totaling to approximately 57 Mgal/d. There were no withdrawals for power generation.

Seepage-run discharge measurements, June 1, 2022, Kanahā Stream, Maui, Hawai'i

This data release contains a comma-delimited ascii file of four same-day, discrete discharge measurements made at sites along selected reaches of Kanahā Stream, Maui, Hawai'i on June 1, 2022. These discrete discharge measurements form what is commonly referred to as a “seepage run.” The intent of the seepage run is to quantify the spatial distribution of streamflow along the reach during fair-weather, low-flow conditions, generally characterized by negligible direct runoff within the reach. The measurements can be used to characterize the net seepage of water into (water gain) or out of (water loss) the stream channel between measurement sites provided that the measurements were made during stable, nonchanging flow conditions (or, in some cases, were made simultaneously during transient flow conditions) and external surface inflows (for example, a tributary) or outflows (for example, a diversion) of water to the reach are quantified and accounted for in the computation of net seepage.
