Basin characteristics rasters for New Jersey StreamStats 2022

The U.S. Geological Survey (USGS), in cooperation with the New Jersey Department of Environmental Protection (NJDEP), calculated several basin characteristics as part of the updated New Jersey StreamStats 2022 application (U.S. Geological Survey, 2022). These datasets are raster representations of various environmental, geological, and land use attributes within the New Jersey StreamStats 2022 study area; they are applied in the New Jersey 2022 application to describe delineated watersheds. This update features improvements in base elevation resolution from 10 meters to 10 feet and stream centerline hydrography from 1:24,000 to 1:2,400, as well as resampling of previously existing datasets to match the 10-foot resolution. The sixteen 8-digit Watershed Boundary Dataset  Hydrologic Unit Codes (HUCs) represented by these datasets are  02020007, 02030103, 02030104, 02030105, 02040101, 02040102, 02040103, 02040104, 02040105, 02040106, 02040201, 02040202, 02040203, 02040206, 02040301, and 02040302 (U.S. Geological Survey, 2016). The StreamStats application provides access to spatial analytical tools that are useful for water-resources planning and management, as well as engineering and design purposes. The map-based user interface can be used to delineate drainage areas, determine basin characteristics and estimate flow statistics, including instantaneous flood discharge, monthly flow-duration, and monthly low-flow frequency statistics for ungaged streams.

Data for multiple linear regression models for estimating Escherichia coli (E. coli) concentrations or the probability of exceeding the bathing-water standard at recreational sites in Ohio and Pennsylvania as part of the Great Lakes NowCast, 2019

Site-specific multiple linear regression models were developed for one beach in Ohio (three discrete sampling sites) and one beach in Pennsylvania to estimate concentrations of Escherichia coli (E. coli) or the probability of exceeding the bathing-water standard for E. coli in recreational waters used by the public.  Traditional culture-based methods are commonly used to estimate concentrations of fecal indicator bacteria, such as E. coli; however, results are obtained 18 to 24 hours post sampling and do not accurately reflect current water-quality conditions.  Beach-specific mathematical models use environmental and water-quality variables that are easily and quickly measured as surrogates to estimate concentrations of fecal-indicator bacteria or to provide the probability that a State recreational water-quality standard will be exceeded. When predictive models are used for beach closure or advisory decisions, they are referred to as “nowcasts”. Software designed for model development by the U.S. Environmental Protection Agency (Virtual Beach) was used. The selected model for each beach was based on a combination of explanatory variables including, most commonly, turbidity, water temperature, change in lake level over 24 hours, and antecedent rainfall.  Model results are used by managers to report water-quality conditions to the public through the Great Lakes NowCast in 2019 (https://pa.water.usgs.gov/apps/nowcast/). Model performance in 2019 (sensitivity, specificity, and accuracy) was compared to using the previous day's E. coli concentration (persistence method).

Basal area in sampling plots, Hakalau Forest NWR

This data release includes data and metadata on tree and shrub identity and basal area within 5 m2 radius plots centered around old growth Acacia koa, planted Acacia koa, old growth Metrosideros polymorpha, and in open, exotic grass dominated sites. Our goal was to ask if understory communities differed between these habitat types and how this relates to other ecosystem factors such as seed rain and exotic grass cover.  Broadly, this study asks what thresholds of seed rain and native and exotic plant cover are needed for passive forest regeneration.

Seed rain in sampling plots, Hakalau Forest NWR

This data release includes data and metadata on bird-mediated and passive seed rain for sites selected to have a range of understory cover under canopy trees (Metrosideros polymorpha and  Acacia koa).  All sites were within Hakalau Forest National Wildlife Refuge on Hawaii Island.  Broadly, this study asks what thresholds of seed rain and native and exotic plant cover are needed for passive forest regeneration. Quantifying natural seed rain rates in different habitat types was needed to better understand how these thresholds function.

Genetic variation in hoary bats (Lasiurus cinereus) assessed from archived samples

Hoary bats are among the bat species most commonly killed by turbine strikes in the midwestern United States. The impact of this mortality on species census size is not understood, due in part to the difficulty of estimating population size for this highly migratory and elusive species. Genetic effective population size (Ne) could provide an index of census population size if other factors affecting Ne are stable. In support of this and other population-genetic studies, we analyzed two temporally spaced cohorts: 96 hoary bats collected in 2009-2010 and an additional 96 collected in 2017-2018. Samples consisted of wing clips removed from archived carcasses and were obtained by agreement from the U.S. Fish and Wildlife Service, the sponsor of this research. All carcasses were originally collected post mortem at wind-turbine facilities in the state of Indiana and subsequently frozen, although for our research purposes the collection location or cause of death is not material. We sequenced restriction-site associated polymorphisms and generated a de novo genome assembly to guide the removal of sex-linked and multi-copy loci, as well as identify physically linked markers. This data release includes the computationally inferred genotypes at 12,915 single-nucleotide polymorphisms (SNPs) for 186 individuals, after excluding six individuals with insufficient data. It also includes the reference genome sequence used to identify physically linked loci and remove sex chromosomes from analysis.

APEX Thaw Depth Data from 2018-2019

Geophysical measurements and related field data were collected by the U.S. Geological Survey (USGS) at the Alaska Peatland Experiment (APEX) site in Interior Alaska from 2018 to 2020 to characterize subsurface thermal and hydrologic conditions along a permafrost thaw gradient. The APEX site is managed by the Bonanza Creek LTER (Long Term Ecological Research). Nine instrument sites were established in April 2018 comprising a buried seismic station for continuous passive recording of the seismic wavefield, and seven of the nine sites were given a borehole for repeat nuclear magnetic resonance (NMR) logging. Between June 2018 and September 2019, measurements of active-layer thaw depth were regularly recorded at each of the nine instrument sites for comparison to the geophysical data. A nominal four measurements were collected in random azimuthal directions within 1 meter (m) distance of the buried seismometer at each instrument site. At sites containing an NMR borehole, an additional four to six measurements were taken within 1 m distance of the borehole location. During collection of electrical resistivity tomography (ERT) data in late August 2018, additional thaw depth measurements were collected at regular electrode intervals along each ERT survey line. Measurements were made with a 250 centimeter (cm) stainless-steel frost probe inserted to the depth of refusal.

Base-flow recession time constant (tau) contours in the Niobrara National Scenic River in Nebraska, 2016-18

This dataset contains base-flow recession time constant (tau) contours that are interpreted from tau values calculated at streamgages in the Niobrara National Scenic River study area. The contours were created by interpolating the calculated tau values using geostatistical kriging methods. Kriging is a geostatistical method that can be used to determine optimal weights for measurements at sampled locations (streamgages) for the estimation of values at unsampled locations (ungaged sites). The kriged tau map could be used (1) as the basis for identifying areas with different hydrologic responsiveness, and (2) in the development of regional low-flow regression equations.  The Geostatistical Analyst tools in ArcGIS Pro version 2.5.2 (Environmental Systems Research Institute, 2012) were used to create the kriged tau map and perform cross validation to determine the root mean square error (RMSE) of the tau map.  The results of the kriging were then exported from ArcGIS to contours.

Delaware River near Wilmington Floating Electromagnetic Surveys

Electromagnetic (EM) geophysical methods provide information about the bulk electrical conductivity of the subsurface. EM data has been widely used to investigate aquifers and geologic structures. In the following study, the United States Geological Survey conducted a boat-towed, waterborne transient electromagnetic (FloaTEM) survey to examine conductivity within the subsurface of the Delaware River channel.  These conductive zones determine the location of the groundwater freshwater/saltwater interface within the Delaware River, downstream from Wilmington, DE. The FloaTEM system transmits a primary electrical current through a transmitter loop (Tx) wire. This creates a static primary magnetic field. Then, the current in the TX loop is subsequently turned off, resulting in secondary electrical currents being induced in the earth. These induced electrical currents decay with time, and this rate of decay in the secondary electrical field is a function of the bulk conductivity of the subsurface material. As the secondary electrical field decays, a secondary magnetic field is induced and measured at a receiver (Rx) loop towed behind the Tx loop. The Rx loop measures the decay of the secondary magnetic field as a function of time (dB/dt). Measured dB/dt decay curves can be inverted to recover the depth-dependent resistivity structure of the earth. FloaTEM surveys were conducted downstream from Wilmington, DE on 8/26/2020 and 8/27/2020. Data on 2/26/2020 were collected around the Augustine Wildlife Area boat ramp, and data on 8/27/2020 were collected near the Collins Landing boat ramp.

Maumee River Legacy and Contaminants of Emerging Concern

Exposure to multiple classes of contaminants, both legacy and those of emerging concern (CECs), were assessed in tree swallow (Tachycineta bicolor) tissue and diet samples from 6 sites along the Maumee River, OH to understand both exposure and possible effects of exposure to those CECs for which there is little avian data.  The six sites represented a gradient from intensive agriculture upstream to highly urbanized and industrial landscapes downstream; 1 – 2 remote Wisconsin lakes were assessed for comparative purposes.  Cytochrome P450 induction, DNA damage, and thyroid function were also assessed relative to contaminant exposure.  Bioaccumulative CECs, such as polybrominated diphenyl ethers (PBDEs) and perfluorinated substances, did not follow any upstream to downstream gradient, but both had significantly greater concentrations along the Maumee River than at the remote lake sites.  Greater exposure to PBDEs was apparent in swallows at or near wastewater treatment facilities than at other sites.  Total polychlorinated biphenyl and total polycyclic aromatic hydrocarbon concentrations were at greater concentrations in swallows at downstream locations compared to upstream sites and were associated with higher ethoxyresorufin-O-dealkylase activity.  Few herbicides or non-organochlorine insecticides were detected in swallow tissues or their food, except for atrazine and its metabolite desethylatrazine, the latter of which was detected in all food samples, eggs, and nearly all nestling carcasses from along the Maumee River.  Few pharmaceuticals and personal care products were detected in tree swallow tissue or sediment samples except for DEET and iopamidol.  Both were detected in most liver samples, but not in eggs, and were detected at the remote lake sites as well.  This is one of the most comprehensive assessments to date of exposure and effects of CECs in birds.

Spatial Models of Wild Bird Risk Factors for Highly Pathogenic A(H5N1) Avian Influenza Virus Transmission

Wild waterfowl (family Anatidae) are reported as secondary transmitters of HPAIV and primary reservoirs for low-pathogenic avian influenza viruses, yet spatial inputs for disease risk modeling for this group have been lacking. Using geographic information software and Monte Carlo simulations, we developed geospatial indices of waterfowl abundance at 1 km resolutions for the breeding and wintering seasons for China, the epicenter of H5N1. Two types of spatial layers were developed: cumulative waterfowl abundance (WAB), a measure of predicted abundance by species, and cumulative abundance weighted by H5N1 prevalence (WPR), whereby abundance for each species was adjusted based on species specific prevalence values. Spatial patterns of the model output differed between seasons, with higher WAB and WPR in the northern and western regions of China for the breeding season and in the southeast for the wintering season. Uncertainty measures indicated highest error in southeastern China for both WAB and WPR.
