Motility of sperm from adult largemouth bass pond exposure to 17 alpha-ethinylestradiol or estrone-atrazine mixture (2018)

Adult largemouth bass have been shown to be sensitive to induction of intersex in response to chronic estrogen exposures over a complete reproductive cycle. Late summer to fall is the period of early gonad recrudescence when spermatogenesis is beginning in preparation for the spawning season in the spring. Our objective was to assess in 2018 whether early gonad recrudescence was a period of sensitivity for induction of intersex and/or alterations in reproductive condition or function. Adult male largemouth bass were exposed in outdoor pond mesocosms from post-spawning to early gonad recrudescence to either 17alpha-ethinylestradiol or to a mixture of endocrine-active substances commonly detected in the Chesapeake Bay watershed (atrazine and estrone). Gonad samples were sent overnight to Wetland and Aquatic Research Center laboratories and sperm motility was measured by computer assisted sperm motion analysis. Overall, male reproductive condition, sperm count, and sperm motility were analyzed.

Early Estimates of Exotic Annual Grass (EAG) in the Sagebrush Biome, USA, 2022 (ver 4.0, June 2022)

These datasets provide early estimates of 2022 fractional cover for exotic annual grass (EAG) species and one native perennial grass species on a bi-weekly basis from May to early July. The EAG estimates are developed within one week of the latest satellite observation used for that version. Each bi-weekly release contains four fractional cover maps along with their corresponding confidence maps for: 1) a group of 16 species of EAGs, 2) cheatgrass (Bromus tectorum); 3) medusahead (Taeniatherum caput-medusae); and 4) Sandberg bluegrass (Poa secunda). These datasets were generated leveraging field observations from Bureau of Land Management (BLM) Assessment, Inventory, and Monitoring (AIM) data plots; Harmonized Landsat and Sentinel-2 (HLS) based Normalized Difference Vegetation Index (NDVI); HLS-based Normalized Difference Water Index (NDWI); other relevant environmental, vegetation, remotely sensed, and geophysical drivers; and artificial intelligence/machine learning techniques. A total of 19,415 AIM plots from years 2016 – 2021 were used to train an ensemble of five-fold regression-tree models using a cross-validation approach (each observation was used as test data once) that developed all the fractional cover maps. The geographic coverage includes arid and semi-arid rangelands in the western U.S at or below 2350-m elevation.
Note: Maps of May 6th, 2022 were developed using satellite observation data no later than April 29.
Maps of May 18th, 2022 were developed using satellite observation data no later than May 13.
Maps of June 3rd, 2022 were developed using satellite observation data no later than May 27.

Data release for the lower seismogenic depth model of western U.S. earthquakes

A model of the lower seismogenic depth distribution of earthquakes in the western United States was developed to support models for seismic hazard assessment that will be included in the 2023 USGS National Seismic Hazard Model. This data release presents a recalibration using the hypocentral depths of events M&gt;1 from the Advanced National Seismic System Comprehensive Earthquake Catalog from 1980 to 2021. For higher precision and better resolution in the model, the data were supplemented with seismicity from southern California that was relocated by Hauksson and others (2012). Along the San Andreas Fault, the deepest seismogenic depths are located at 23 km around the Cholame segment, whereas the shallowest depths are located at about 10 km along the Rogers Creek and Macaama faults. In the western United States outside of California, the depth varies between 10 and 25 km with an average around 14 km.

Concentrations of per- and polyfluoroalkyl substances (PFAS) in tapwater collected throughout the United States, 2021-22

This dataset contains the concentration and quality assurance results for 34 per- and polyfluoroalkyl substances (PFAS).  409 residential and commercial tapwater samples were collected once between May 2021 and May 2022, in the contiguous U.S., Alaska, Hawaii, Puerto Rico, and U.S. Virgin Islands.  Of these samples 252 were from publicly supplied tapwater locations, and 155 were sourced from private wells, springs or catchment vessels.  Additionally, three surface-water samples were collected in New Hampshire (as denoted with a site code suffix of '_SW' in Table 2a). An additional 85 samples were collected at 3 locations (privately sourced tapwater samples in New Jersey (30) and South Carolina (20), and a publicly supplied source in New Jersey (35)) between September 27, 2021 and December 20, 2021 to evaluate PFAS concentrations over time.  Individual homeowner kits were shipped with supplies and protocols so the homeowner could collect and return the samples for analysis.  Thirty-six quality-assurance field-blank samples were also collected.  Quality-assurance matrix spike and surrogate percent recovery results are also presented.  Samples were analyzed at the U.S. Geological Survey, National Water Quality Laboratory in Denver, Colorado.  For privacy purposes, all sample locations are anonymized.

Microbial Populations in PFHxSAm (perfluorohexane sulfonamido propyl amine) Biodegradation Microcosms

Water resources around the world are contaminated with per- and polyfluoroalkyl substances (PFAS) due to releases from point sources on military installations, fire training centers, and chemical manufacturing sites. Non-point sources have also been identified including wastewater effluent, landfills, and biosolids application. PFAS are a major concern to myriad stakeholders as some are known to bioaccumulate, they have eco-toxicity effects, and they are highly recalcitrant. PFAS are often called “forever chemicals” due to their environmental persistence but many precursor PFAS are transformed in the environment by microbes. Recent work has shown that PFAS can be biologically degraded in laboratory studies, but the microbial populations catalyzing degradation are poorly characterized. We conducted laboratory microcosm experiments to investigate the biotransformation of perfluorohexane sulfonamido propyl amine (PFHxSAm), a predominant precursor in 3M Aqueous Film Forming Foam (3M AFFF), by native microbial populations in upwelling sediment-water slurries from Ashumet Pond, MA. Ashumet Pond is affected by multiple PFAS-contaminated groundwater plumes from Joint Base Cape Cod, MA. The field collected samples were used to construct aerobic microcosms for monitoring PFHxSAm biodegradation. Microbial community composition was analyzed at 4 timepoints using Illumina 16S rRNA gene iTag sequencing and quantitative PCR (qPCR) targeting bacterial 16S rRNA genes. Experiments were performed in triplicate and abiotic controls were included in each experiment. The data release contains the results of Illumina iTag sequencing and qPCR for microbial community characterization. Four tables are provided that describe the experimental bottles, the results of DNA quantification, the results of biomass estimates using qPCR, and the taxonomic data based on sequencing results (provided as a biom file).

Multispectral aerial imagery collected during uncrewed aircraft systems (UAS) operations: Plum Island Estuary and Parker River NWR (PIEPR), Massachusetts, November 14, 2017 and March 28, 2019

Low-altitude (80 and 100 meters above ground level) digital images were collected by the USGS Woods Hole Coastal and Marine Science Center (WHCMSC) Aerial Imaging and Mapping Group (AIMG) over an area of the Plum Island Estuary and Parker River National Wildlife Refuge (NWR) in Massachusetts on November 14, 2017 and March 28, 2019 to document marsh stability over time and quantify sediment movement. A 3DR Solo uncrewed aircraft systems (UAS) was equipped with either a Ricoh GR II digital camera for true color photos, which can be used to produce digital elevation models and ortho images, or a MicaSense RedEdge multispectral camera for five-banded imagery (blue, green, red, red edge, and near-infrared spectral bands), which can be used to classify vegetation. The MicaSense camera covered a smaller subsection of the same polygonal area of the marsh that the Ricoh imaged. Some photographs contain black and white targets used as ground control points (GCPs), which were surveyed by a field crew with a high-precision Real-Time Kinematic Global Positioning System. This data release includes the original images from both cameras, as well as a CSV file containing the latitude and longitude coordinates, in Universal Transverse Mercator Zone 19N referenced to the North American Datum of 1983, of the ground control points needed to complete any photogrammetry projects using the original photographs, and GPS transect points used to evaluate the photogrammetry products created.

Digital subsurface data from previously published contour map of the top of the Wilcox Group, northern Gulf of Mexico coastal region

The lower Paleogene Wilcox Group crops out around the northern edge of the Gulf of Mexico Basin and is a major coal-bearing unit and a primary oil and gas producer in the lower Paleogene section of the Gulf Coast region. The outcrop distribution of the Wilcox Group and other coal-bearing strata of the Gulf Coast region was compiled as part of a U.S. Geological Survey National Coal Assessment (Warwick and others, 1997). A structure contour map of the top of the Wilcox Group was constructed as part of a U.S. Geological Survey Petroleum Systems and Geologic Assessment of Oil and Gas of the northern Gulf of Mexico coastal region (Warwick, 2017). This surface, mainly constructed using data from oil and gas wells, depicts the overall configuration of the Wilcox Group near the outcrop belt, within the Mississippi Embayment, and near the present-day coastline where the Wilcox Group crosses over the Lower Cretaceous shelf margin in the subsurface. The structure contour map of the top of the Wilcox Group was used to help define the thermal maturity of a specific source-rock interval as part of the oil and gas assessment. 
This digital data release captures in digital form the mapped outcrop distribution and structural configuration of the Wilcox Group from the previously published U.S. Geological Survey assessment-related studies of the Gulf Coast region (Warwick and others, 1997; Warwick, 2017). Both the geologic map polygons and structure contours were digitized and attributed as GIS data sets so that these data could be used in digital form as part of U.S. Geological Survey and other studies of the region.
