Transient Electromagnetics, Passive Seismic, and Borehole Electromagnetics, Gamma, and Nuclear Magnetic Resonance Methods to Characterize Glacial Sediments in East Falmouth, Massachusetts, Near Nantucket Sound

In March 2016, the U.S. Geological Survey drilled a borehole, MA-FSW-750-0100, through the unconsolidated sediments and 1.5 m into the bedrock in East Falmouth, Massachusetts, to improve understanding of the glacial history and hydrologic properties of the Cape Cod aquifer.  Prior to drilling, candidate sites were investigated using surface geophysical methods. Passive seismic horizontal-to-vertical spectral ratio (HVSR) methods were used to estimate the depth of the unconsolidated deposits over bedrock.  Transient electromagnetic (TEM) surveys were conducted to characterize the lithology and salinity of formation water in the subsurface, which was used to plan the borehole completion. The specific conductance of the fluids extracted from drill cuttings was measured at the time of drilling.  Borehole MA-FSW-750-0100 was logged with geophysical methods including natural gamma radiation and electromagnetic induction (EMI) logs to identify changes in the lithology and fluid properties of the subsurface.  A pulsed magnetic resonance borehole tool was used to characterize hydraulic properties of the aquifer. Borehole nuclear magnetic resonance (bNMR) logs were collected to measure the water content and estimate the pore-size distribution and hydraulic conductivity (K) over the depth of the borehole.

Oregon spotted frog (Rana pretiosa) observations in Oregon (ver. 6.0, March 2025)

This dataset contains information from surveys conducted 2016-2024 by USGS as part of an ongoing Oregon spotted frog (Rana pretiosa) monitoring effort in Oregon. USGS research activities 2016-2024 were divided into seven study design categories: breeding (egg mass counts), mid-level (visual encounter surveys for occupancy monitoring), apex (mark-recapture), telemetry, trapping, water quality (skin microbiome swabbing), and genetics (egg mass embryo or toe-clip tissue samples). Data consist of Oregon spotted frog observations aggregated by date, location, life stage, sex, and project. These data were compiled from multiple studies employing different survey methods, thus we caution users that counts are not directly comparable among projects; any counts may represent multiple detections of the same individual.

Codebook vectors and predicted rare earth potential from a trained emergent self-organizing map displaying multivariate topology of geochemical and reservoir temperature data from produced and geothermal waters of the United States

This data release consists of three products relating to a 82 x 50 neuron Emergent Self-Organizing Map (ESOM), which describes the multivariate topology of reservoir temperature and geochemical data for 190 samples of produced and geothermal waters from across the United States. Variables included in the ESOM are coordinates derived from reservoir temperature and concentration of Sc, Nd, Pr, Tb, Lu, Gd, Tm, Ce, Yb, Sm, Ho, Er, Eu, Dy, F, alkalinity as bicarbonate, Si, B, Br, Li, Ba, Sr, sulfate, H (derived from pH), K, Mg, Ca, Cl, and Na converted to units of proportion. The concentration data were converted to isometric log-ratio coordinates (following Hron et al., 2010), where the first ratio is Sc serving as the denominator to the geometric mean of all of the remaining elements (Nd to Na), the second ratio is Nd serving as the denominator by the geometric mean of all of the remaining elements (Pr to Na), and so on, until the final ratio is Na to Cl. Both the temperature and log-ratio coordinates of the concentration data were normalized to a mean of zero and a sample standard deviation of one. The first table is the mean and standard deviation of all of the data in this dataset, which is used to standardize the data.  The second table is the codebook vectors from the trained ESOM where all variables were standardized and compositional data converted to isometric log-ratios. The final tables provides are rare earth element potentials predicted for a subset of the U.S. Geological Survey Produced Waters Geochemical Database, Version 2.3 (Blondes et al., 2017) through the used of the ESOM. The original source data used to create the ESOM all come from the U.S. Department of Energy Resources Geothermal Data Repository and are detailed in Engle (2019).

Wetland Moist Soil Seed Productivity Maps for the Central Valley of California 2007 - 2017

We produced a series of maps of moist soil seed plants within managed wetlands in the Central Valley of California from 2007-2011 &amp; 2013-2017. Moist soil seed plants, such as swamp timothy (Crypsis schoenoides) and watergrass (Echinochloa crusgallim), are a critical food source for migratory birds. For each of the Moist Soil Seed maps from 2007 to 2017, we mapped productivity of swamp timothy where swamp timothy was mapped according to a multiple regression of the average log seed head weight per Landsat pixel to Landsat derived values for green chlorophyll index (NIR/green - 1), swir1 reflectance, red green simple ratio (red/green) and SSURGO derived percent clay (STprod). For areas mapped as watergrass, we mapped the green chlorophyll index as an indicator of productivity (WGprod). The final maps show the productivity and extent of two dominant moist soil seed plants within managed wetlands in the Central Valley of California.

Organic Petrography and Diagenesis of Leonardian Mudrocks and Carbonates, Midland Basin, Texas (2018)

As part of a larger study, organic petrographic features of Leonardian Wolfcamp A repetitive siliceous and calcareous mudrock and fine-grained carbonate lithofacies cycles occurring in the R. Ricker #1 core from Reagan County, Midland Basin, Texas were evaluated. The objectives of the petrographic investigation were to estimate thermal maturity, identify organic matter types and abundances, and identify the presence or absence of migrated hydrocarbons. An integrated analytical program included geochemical screening [total organic carbon (TOC) content by LECO, programmed pyrolysis by HAWK, including from solvent-extracted samples], X-ray diffraction mineralogy, organic petrography, SEM-EDS including correlative light and electron microscopy (CLEM) and micro-FTIR analyses of solid bitumen. The data indicate all samples are early to middle oil window thermal maturity with solid bitumen reflectance (BRo) values of 0.55 to 0.86% and Tmax of 440 to 455°C. Organic matter is predominantly solid bitumen in all lithofacies with minor contributions from inertinite. Solid bitumen abundance decreases from siliceous mudrock (TOC &gt;3.0 wt.%) to calcareous mudrock (TOC 1.0 to 3.0 wt.%) to fine-grained carbonate (TOC &lt;1.0 wt.%) lithofacies. Interpretations of petrographic data suggest siliceous and calcareous mudrocks are source rock lithofacies and contain solid bitumen (with petroleum generation potential) that is residual from conversion of an original Type II sedimentary kerogen. Whereas, fine-grained carbonates are interpreted as reservoir lithofacies which contained little or no original oil-prone sedimentary organic matter and at present-day contain only a minor component of migrated solid petroleum sourced from adjacent siliceous and calcareous mudrock lithofacies.

Synoptic sampling data from Illinois Gulch and Iron Springs near Breckenridge, Colorado, August 2016 and September 2017

Two synoptic sampling campaigns were conducted near Breckenridge, Colorado, to quantify metal loading to Illinois Gulch, a tributary of the Blue River. The first campaign, conducted in August 2016, was designed to determine the degree to which Illinois Gulch loses water to the underlying mine workings, and to determine the effect of these losses on observed metal loads. The second campaign, conducted in September 2017, was designed to evaluate metal loading within Iron Springs, a subwatershed that was responsible for the majority of the metal loading observed in 2016. A continuous, instream injection of a sodium bromide (NaBr) tracer was initiated at the head of the respective study reaches several days prior to both synoptic sampling campaigns and maintained throughout the duration of each study. Bromide concentrations were subsequently used to determine streamflow in gaining stream reaches using the tracer-dilution method, and as an indicator of hydrologic connections between the Illinois Gulch and subsurface mine workings. Streamflow losses to the mine workings were quantified using a series of magnesium chloride slug additions conducted in August 2016, wherein specific conductivity readings were used as a surrogate for the tracer concentration.  Study results indicate that Illinois Gulch loses water in the vicinity of the Puzzle Extension Shaft, and that water leaving the stream enters the subsurface mine workings. These losses are evidenced by the results of the slug additions and the elevated bromide concentrations observed at a collapsed mine portal in the Iron Springs subwatershed (Willard Adit 1). The primary sources of metal loading to the overall Illinois Gulch study reach include diffuse springs and groundwater near the toe of the Iron Springs mine dump and Willard Adit 1.

Seafloor Elevation Change From 2004 to 2016 at Looe Key, Florida Keys

The U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center conducted research to quantify bathymetric changes at Looe Key near Big Pine Key, Florida (FL), within a 16.4 square-kilometer area between 2004 and 2016. USGS staff used light detection and ranging (lidar)-derived data acquired by the U.S. Army Corps of Engineers (USACE) Joint Airborne Lidar Bathymetry Technical Center of eXpertise (JALBTCX) between December 1 and 31, 2004 (USACE-JALBTCX) and the National Oceanic and Atmospheric Administration (NOAA) between July 21 and November 21, 2016 (NOAA, 2017) to assess changes in seafloor elevation and structure that occurred during this time. An elevation change analysis between the 2004 USACE and 2016 NOAA lidar data was performed to quantify and map impacts to seafloor elevation and determine elevation and volume change statistics for ten habitat types found at Looe Key. Data were collected under Florida Keys National Marine Sanctuary permit FKNMS-2016-068.

Modeled Top of the Wanapum Basalt Geomodel Unit (wntop_f)

The wntop_f grid represents the modeled elevation of the top of the Wanapum Basalt geomodel unit 
at a 500 foot resolution. It is one grid of a geomodel that consists of eleven grids and a spatial extent 
polygon shapefile.  As part of a U.S. Geological Survey Groundwater Resources Program study, a 
three-dimensional geomodel was constructed for approximately 53,000 mi2 of the Columbia Plateau 
in Washington, Oregon, and Idaho. This geomodel was constructed to define the general aquifer 
system geometry for use in a regional numerical groundwater flow model. Simplifications and 
assumptions consistent with this ultimate goal and the uncertainty in the available data were made. 
The geomodel units consist of Miocene age Columbia River Basalt Group strata and younger alluvial 
overburden covering approximately 44,000 mi2. Data were compiled from numerous databases and 
detailed studies completed during the past three decades. These data include stratigraphic 
interpretations made on more than 13,000 wells and a contiguous compilation of surficial geology 
and structural features spanning the study area. These data were simplified and used to construct 
piecewise-smooth trend surfaces that represent upper and lower subsurface geomodel unit boundaries 
in this complex folded and faulted terrain.  The smoothness of the surfaces implicitly represents 
uncertainty in prediction of each surface resulting from data gaps, errors in borehole interpretations, 
errors in mapped contact locations, and uncertainty in the shape of the paleo-surface upon which 
flood basalts were emplaced. Using a rule-based algorithm, surfaces were then recombined to 
construct a fully three-dimensional model with a 500-foot grid resolution that is consistent with the 
data and for which error estimates may be made. The modeling process yielded improved estimates 
of unit volumes, refinement of location of large structural features, and identification of features that 
may be important for ongoing groundwater studies.

Polychlorinated biphenyl concentrations in adult walleye from the Fox River (Wisconsin) population, 2014

Adult walleye (10 females and 10 males) were caught in Fox River (Wisconsin) during April 2014.  Total length, weight, and age were determined for each of the walleye.  Whole-fish homogenates were prepared during 2017.  Lipid concentration and polychlorinated biphenyl (PCB) congener concentrations were determined in each of the homogenates during 2017-2018.  For each sample, PCB congener concentrations were summed to yield total PCB concentration.   All lipid and PCB congener terminations were made at the University of Michigan School of Public Health in Ann Arbor, Michigan.
