Mercury and Methylmercury Stable Isotope Measurements in Giant Petrels

Methylmercury (MeHg) and total mercury (HgT) stable isotope measurements were made by the USGS Mercury Research Lab (MRL) in different organs on the Giant Petrels (Macronectes spp.) to examine internal mercury cycling in these seabirds. These data were collected as a compliment to x-ray spectroscopy measurements made by the University of Grenoble, France. The tissues and feathers of the southern giant petrels exhibit large variability in mercury-202 isotope values (δ202HgT), which are typically used to ascertain Hg sources in the environment. These values follow a pattern across all individuals based on tissue type: feathers (δ202HgT = 2.74 ± 0.16‰, n =5, mean ± standard deviation) &gt; brain (δ202HgT = 1.09 ± 0.77‰, n = 3)  &gt; liver (δ202HgT = 0.04 ± 0.11‰, n = 5) &gt; kidneys (δ202HgT= 0.01 ± 0.25‰, n = 5)&gt; muscle (δ202HgT = -0.80 ± 0.23‰, n = 5). The δ202HgT for liver tissues are within the range of literature data for seabirds (−0.64‰ &lt; δ202Hgl &lt; 0.68‰), whereas δ202Hg for feathers are modestly higher than those measured previously for seabirds (1.10‰ &lt; δ202Hgf &lt; 2.35‰). Notably, muscle tissues exhibit considerably lower δ202HgT values than liver tissues (on average 0.84‰), counter to observations to other birds and mammals, and were as much as ~−4‰ enriched in light isotopes compared to feathers. The δ202MeHg values, associated with just the MeHg contents within the tissues, for organs and feathers were constrained between 0.90 and 3.05 ‰ (n =9).

Survey of metals in soils and associated endemic plants across the historic Harshaw Mining District, Southern Arizona

The legacy of mining exploration and operations can remain for decades to centuries if not treated, posing risks to human and animal health due to fugitive dispersal of metal(loid) laden dust and water. The use of endemic plants is key to the success of phytostabilization because endemics are adapted to the conditions prevailing in local mine sites. To this end, we evaluated the phytostabilization potential of endemic plant populations growing at two unmined mineralized sites and on metallic wastes at two historic mine operations and two sites un-impacted by mining operations within the Harshaw Mining District in southern Arizona. Included in this dataset are the physical (pH, Electrical Conductivity, total carbon and nitrogen, DNA concentrations) and elemental (total metals concentrations) of mine wastes and associated soils, and the elemental composition of endemic plants growing on those soils (total metals concentrations)

Lidar-derived imagery and digital elevation model of Monroe County, West Virginia at 3-meter resolution

These raster datasets are 3-meter lidar-derived images of Monroe County, West Virginia, and were created using geographic information systems (GIS) software. Lidar-derived elevation data acquired in late December of 2016 were used to create a 3-meter resolution working digital elevation model (DEM), from which a hillshade was applied and a topographic position index (TPI) raster was calculated. These two rasters were uploaded into GlobalMapper, where the TPI raster was made partially transparent and overlaid the hillshade DEM. The resulting image was exported to create a 3-meter resolution lidar-derived image. The data is projected in North America Datum (NAD) 1983 UTM Zone 17.

Decompartmentalization Physical Model (South Florida Water Management District) Periphyton Abundance and Biovolume Data 2017–21

Periphyton is a complex community of detritus, bacteria, fungi, and algae that grows attached to submerged substrates. Assemblage structure data for algae and cyanobacteria from periphyton samples were collected on a monthly basis from 2017 to 2021. Compiled data were reported as absolute abundance (cells) and biovolume per volume as well as absolute abundance (cells) and biovolume per area at four locations increasing in distance East of the L-67 canal in Water Conservation Area 3 (WCA 3) of the Florida Everglades immediately north of Everglades National Park. The periphyton assemblages were analyzed for five sample types including periphyton plates (Plates), invertebrate inclusion and exclusion plates (Inverts), biological oxygen demand cores (BOD), vertical/sediment traps (VertSedTrap), and metaphyton cores (MetaCore).

In Support of the U.S. Fish and Wildlife Service 3-Bat Species Status Assessment: Predicted Wind Take Allocated To Hibernacula Each Year Under Current and Future Scenarios

Through the North American Bat Monitoring Program (NABat), United States Geological Survey (USGS) provided technical and science support to assist in U.S. Fish and Wildlife Services’ (USFWS) Species Status Assessment (“SSA”) for the northern long-eared bat (Myotis septentrionalis), little brown bat (Myotis lucifugus), and tri-colored bat (Perimyotis subflavus). USGS facilitated the SSA data call, provided data archival for repeatable and transparent analyses, provided statistical support to assess the historical, current, and future population status for each of the three species, and developed a demographic projection tool to evaluate future viability of each species under multiple threat scenarios.
These data represent the predicted bat take from wind energy allocated to each known winter hibernacula (at the resolution of the NABat grid cell) for each species, under several scenarios. These annual wind take predictions for each hibernacula and scenario were produced as inputs for a separate demographic scenario modeling effort (Wiens et al. 2021) in support of the U.S. Fish and Wildlife Services’ 3-Bat SSA.  The predicted take allocated each year to each hibernacula was dependent on: 1) current or future distribution of wind energy on the landscape, 2) the curtailment status (none, summer only, summer and fall) of current wind energy facilities, 3) mortality rate (take/megawatt of rated capacity), under lower (25th percentile), mean, and upper (75th percentile) scenarios based on estimates provided by USFWS, 4) the predicted year of arrival of Pd (Pseudogymnoascus destructans) for each location based on 2 alternative models which used data from the county-level USGS pd surveillance map, 5) the species' proportion of all bat take in each USFWS region and Canadian province, based on estimates provided by USFWS (both before and after the arrival of Pd), 6) the mean and maximum migration distances of each species, 7) the last observed count of each hibernacula, 8) the distance between each hibernacula and wind energy location, and 9) an exponential migration kernel (distance decay function) based on the mean migration distance of each species. The total take at each wind energy grid cell was predicted based on items 1-5, and take was reallocated among hibernacula given items 6-9. Scenario levels included 4 time periods (current, 2030, 2040, 2050), 2 alternative pd spread models, 2 future wind energy development scenarios (high cost = low future build-out, low cost = high future build out) using models provided by the National Renewable Energy Lab (NREL), and 3 scenarios for take/megawatt estimates (mean, 25th percentile,75th percentile), for a total of 42 scenarios for each species.

Datasets from the focus group series of stakeholder engagement efforts to inform integrated water availability assessment data delivery

The U. S.  Geological Survey- Water Resources Mission Area is currently developing Integrated Water Availability Assessments (IWAAs) — multi-extent (regional and national), stakeholder driven, near real-time water availability census and prediction for human and ecological uses. To provide appropriate user accessibility to data delivery systems developed for IWAAs, a user-centered design process including stakeholder focus groups was used with the objective of determining potential water data user needs and preferences. The metadata presented here contains the questions and answers associated with the stakeholder focus group series held from 08/04/2020 to 09/16/2020. The question set and prompts used during these focus groups were divided into the categories of decisions and data. Additionally, each focus group date has a dataset organized by a participant code, question type, and questions and answers according to decision type (decisions or data). Entries indicated as “participant did not answer question” indicates no response to the question, whereas entries indicated as “NA” indicates a response was given earlier and empty cells were filled out with the letters NA. Lastly, data analysis was presented as requirement statements indicating stakeholder data format and needs per each focus group date and location.

Brown treesnake capture and morphometric data using live mouse- and bird-lure traps on Guam, 2013

We deployed 30 trap stations consisting of three combinations: isolated bird-lure traps, isolated mouse-lure traps, or paired stations to evaluate snake capture as a function of lure. At the paired stations, we included two traps: one bird-lure trap and one mouse-lure trap. All stations were at least 60 meters (m) apart and each of the station treatments was replicated 10 times. Traps at paired stations ranged from 1.7 to 6.7 m apart (mean 3.22 ± 0.46) depending on availability of vegetation from which to suspend traps. Both mouse-lure traps and bird-lure traps were adapted from standard modified commercial minnow traps composed of 6 millimeter (mm) galvanized steel mesh. The traps were operational for 67 trap nights to get a time trend as refuse odor accumulated in and under the trap and to evaluate trap efficacy as the Brown Treesnake (BTS) population was suppressed. Traps were checked every 48 to 72 hours for a total of 29 trap checks. Trap stations were located on Guam National Wildlife Refuge outside of the BTS exclosure fence. We used three areas outside of the snake exclosure with balanced station treatments at each site. The habitat was mainly limestone forest.

Grain size, bulk density, and organic carbon of sediment cores from San Pablo Bay and Grizzly Bay, California, 2020 (ver. 1.1, March 2025)

Bed sediment samples were collected in San Pablo Bay and Grizzly Bays on eight days from January through September 2020, to analyze for sediment properties including bulk density, particle size distribution, and percent organic carbon. Sediment samples were collected from a small vessel near pre-established USGS instrument moorings using a Gomex box corer that was subsampled with three push cores (37 mm in diameter) per Gomex core. Six subsamples were collected from the top 5 centimeters (cm) of each push core, a few push cores included the top 8 cm. The top two subsamples were each 0.5 cm thick, and all following subsamples were each 1 cm thick. Push core samples from the first, third, and fifth centimeter depth were analyzed for grain size and percent organic carbon, while all 6 sections were analyzed for bulk density. Data are provided in a comma-delimited values spreadsheet. These data were collected as part of a collaborative project with the USGS California Water Science Center and the USGS Water Mission Area on physical and biological controls on sediment erodibility, funded by the USGS Priority Ecosystems Program for San Francisco Bay and Delta and the USGS Coastal Marine Hazards and Resources Program.

Distribution of particle size in suspension at various depths from San Pablo Bay and Grizzly Bay, California, 2020

These data present suspended particle size distributions collected by the U.S. Geological Survey (USGS) Pacific Coastal and Marine Science Center within two embayments of San Francisco Bay. Data were collected at one site in San Pablo Bay and one site in Grizzly Bay from January through February 2020 by deploying a Sequoia Scientific Laser In-situ Scattering and Transmissometry instrument (LISST 200x) from a small vessel near pre-established USGS instrument moorings. At both sites, data were collected on four dates at three depths, generally near the water surface, at mid depth, and near the sediment bed, for 1-3 minutes at each depth. LISST volume concentrations are most accurate when the optical percent transmission is above 30; when this is true, light passing through the sample volume is unlikely to be scattered by more than one particle. These files contain all samples collected; judgment should be applied when using them. Users are advised to check metadata and instrument information carefully for applicable time periods of specific data.

Hydrodynamic time-series data from San Pablo Bay and Grizzly Bay, California, 2020

Hydrodynamic and sediment transport time-series data, including water depth, velocity, turbidity, conductivity, and temperature, were collected by the U.S. Geological Survey (USGS) Pacific Coastal and Marine Science Center within two embayments of San Francisco Bay. Data were collected in San Pablo Bay and Grizzly Bay from January to June 2020 at seven locations. Data files are grouped by area (shallows of San Pablo Bay, channel of San Pablo Bay, and shallows of Grizzly Bay). Each shallow site contained a variety of sensors located on two tripods, while the channel site consisted of one tripod. Users are advised to assess data quality carefully, and to check metadata for instrument information, as platform deployment times and data-processing methods varied.

Meteorological data from Grizzly Bay, California, 2020

Meteorological data, including wind speed, wind direction, air temperature, relative humidity, and air pressure, were collected by the U.S. Geological Survey (USGS) Pacific Coastal and Marine Science Center at a site located in Grizzly Bay, California. A Vaisala WXT530 meteorological station was mounted atop of a dolphin-type mooring structure, from January to June 2020. The data were truncated based on deployment and recovery times of hydrodynamic time-series data, spurious data points from the wind sensor were removed, and the file was written to netCDF. Spurious points were identified based on a recorded wind speed of 0. These points were set to NaN (Not a Number). Users are advised to assess data quality carefully, and to check metadata for additional instrument information.

National Assessment of Oil and Gas Quarter-Mile Cells - Upper Cretaceous Taylor and Navarro Groups, Western Gulf Province (047)

Cell maps for each oil and gas assessment unit were created by the USGS to illustrate the degree of exploration, type of production, and distribution of production in an assessment unit or province. Each cell represents a quarter-mile square of the land surface, and the cells are coded to represent whether the wells included within the cell are predominantly oil-producing, gas-producing, both oil and gas-producing, dry, or the type of production of the wells located within the cell is unknown. The well information was initially retrieved from the IHS Energy Group, PI/Dwights PLUS Well Data on CD-ROM, which is a proprietary, commercial database containing information for most oil and gas wells in the U.S.  Cells were developed as a graphic solution to overcome the problem of displaying proprietary PI/Dwights PLUS Well Data.  No proprietary data are displayed or included in the cell maps.  The data from PI/Dwights PLUS Well Data are current as of 2003.
