San Francisco Bay region 3D seismic velocity model v21.0

This three-dimensional (3D) seismic velocity model includes a detailed domain covering the greater San Francisco Bay urban region and a regional domain at a coarser resolution covering a larger region. Version 21.0 is a re-release of v08.3.0 in a new storage scheme. The model was constructed by assigning elastic properties (density, Vp, Vs, Qp, and Qs) to grids of points based on the geologic unit and depth from the ground surface. The model is stored in HDF5 files using the GeoModelGrids (https://geomodelgrids.readthedocs.io) storage scheme (see the README.md file for an overview). GeoModelGrids provides a high-level interface for accessing the model. The model can also be accessed using the HDF5 application programming interface provided with many programming languages and tools, but the user will be responsible for all coordinate transformations.

Autonomous Flow-Thru (AFT) pH data of the West Florida Shelf: USGS Cruise 11BHM04

The United States Geological Survey (USGS) is conducting a study on the effects of climate change on ocean acidification within the Gulf of Mexico; dealing specifically with the effect of ocean acidification on marine organisms and habitats. To investigate this, the USGS participated in two cruises in the West Florida Shelf and northern Gulf of Mexico regions aboard the R/V Weatherbird II, a ship of opportunity lead by Dr. Kendra Daly, of the University of South Florida (USF). The cruises occurred September 20 - 28 and November 2 -4, 2011. Both left from and returned to Saint Petersburg, Florida, but followed different routes (see Trackline). On both cruises the USGS collected data pertaining to pH, dissolved inorganic carbon (DIC), and total alkalinity in discrete samples. Discrete surface samples were taken during transit approximatly hourly on both cruises, 95 in September were collected over a span of 2127 km, and 7 over a trackline of 732 km line on the November cruise. Along with the surface samples, another set of samples were taken at various depths at stations; 27 in September at four stations and 15 in November at five stations. In addition to the discrete samples flow-through data was also collected on both cruises in a variety of forms. Surface CTD data was collected every five minutes which includes temperature, salinity, and pH. In addition, two more flow-through instruments were setup on both cruises that recorded pH and CO2 every 15 minutes. Corroborating the USGS data is the vertical CTD profiles collected by USF, using the following sensors: CTD, oxygen, chlorophyll fluorescence, optical backscatter, and transmissometer. Additionally, discrete depth samples for nutrients, chlorophyll, and particulate organic carbon/nitrogen were collected.

St. Croix National Scenic Riverway, Substrate Characterization of the St. Croix River near Prescott, WI, 2018

Hydroacoustic (sonar) data were collected for the Mississippi, St. Croix, and Minnesota Rivers for the development of high-resolution bathymetry and sidescan imagery. Small areas containing priority mussel habitat had additional collection efforts to map water velocities and bottom composition. Combining these data in a GIS can provide key components to characterizing physical benthic habitat for native mussels in a riverine environment. This information is highly desired by the National Park Service to more accurately assess environmental factors that influence native mussel distribution. The collaborative effort was funded by the Legislative-Citizen Commission on Minnesota Resources (LCCMR) Environment and Natural Resources Trust Fund (ENRTF), to help maintain and enhance Minnesota’s environment and natural resources.

Horizontal-to-Vertical Spectral Ratio (HVSR) Passive-seismic Data Collected in the Des Moines River Floodplain, Des Moines, Iowa, 2018

In summer 2018, a total of 43 passive seismic surveys were conducted in the Des Moines River floodplain. The horizontal-to-vertical spectral ratio (HVSR) method is a passive seismic technique that uses a three-component seismometer to measure the vertical and horizontal components of ambient seismic noise. A resonance frequency (f0) is induced in the unconsolidated deposits when there is a substantial contrast (greater than 2:1) in shear-wave acoustic impedance between the overburden and the bedrock. The f0 is determined from the analysis of the spectral ratio of the horizontal and vertical components of the seismic data. The thickness of the overburden can be related to the f0. In general, lower f0 relates to thicker sediments, and higher f0 relates to relatively thinner overburden.
This data release contains a text file (Readme_HVSR.txt) that explains data files and processing references, 6 .zip folders 5 related to survey line(s) on a given date and one for individual measurements not related to survey lines with each zip folder containing measurement site folders and original data files and resultant measurement report (.trc, .saf or .dat, and .doc) , a notes file for archiving surface-geophysical data (HVSR_Archive_Notes_DesMoinesIA.csv), and another comma-separated values file (HVSR_Index_DesMoinesIA.csv) that can be used to help navigate the data files.
Field notes taken at the time of data collection are not included in this data release but are available upon request.

Gene annotations for the hoary bat (Lasiurus [Aeorestes] cinereus) and alignments with other bat gene sets for evolutionary analysis

Bats of the genus Lasiurus occur throughout the Americas and have diversified into at least 20 species among three subgenera. The hoary bat (Lasiurus cinereus, or synonymously, Aeorestes cinereus) is highly migratory and ranges farther across North America than any other wild mammal. Despite the ecological importance of this species as a major insect predator, and the particular susceptibility of lasiurine bats to wind turbine strikes, our understanding of hoary bat ecology, physiology, and behavior remains poor. To better understand adaptive evolution in this lineage, we used whole-genome sequencing to identify protein-coding sequence and explore signatures of positive selection. Gene models were predicted with Maker and compared to seven well-annotated, phylogenetically representative species. Of 9,447 single-copy orthologous groups that met evaluation criteria, 150 genes had a significant excess of nonsynonymous substitutions along the L. cinereus branch (P&lt; 0.001 after manual review of alignments). Analysis of mouse orthologs with DAVID did not identify significant enrichment of ontology categories, but selected genes as a group had biased expression, most strongly in thymus tissue. We identified 23 selected genes with reported immune functions as well as a divergent paralog of Steep1 within suborder Yangochiroptera. Seventeen genes had roles in lipid and glucose metabolic pathways, partially overlapping with 15 mitochondrion-associated genes. The genomic distribution of positively selected genes differed significantly from background expectation by discrete Kolmogorov-Smirnov test (P&lt;0.001). The top three physical clusters all coincided with islands of conserved synteny predating Mammalia, the largest of which shares synteny with the human cat-eye critical region (CECR) on 22q11.

Tidal Datums, Tidal Range, and Nuisance Flooding Levels for Chesapeake Bay and Delaware Bay

This U.S. Geological Survey data release provides data on spatial variations in tidal datums, tidal range, and nuisance flooding in Chesapeake Bay and Delaware Bay. Tidal datums are standard elevations that are defined based on average tidal water levels. Datums are used as references to measure local water levels and to delineate regions in coastal environments. Nuisance flooding refers to the sporadic inundation of low-lying coastal areas by the maximum tidal water levels during spring tides, especially perigean spring tides (also known as king tides). Nuisance flooding is independent of storm event flooding, and it represents a cumulative or chronic hazard. The data were obtained by following a consistent methodology and at sufficient spatial resolution to resolve the distinct and complex features of each bay system. Tidal water levels were simulated by using the ADCIRC model system for the entire 2016 year. The year 2016 was chosen because it corresponded with the maximum magnitude of the combined 18.6-year and 4.4-year tidal modulations. The estuarine and bay areas were resolved with horizontal resolutions on the order of tens to hundreds of meters. The ADCIRC simulations provide time series of water levels at each computational point of an unstructured grid that covers the entire area of interest—from the open ocean to overland areas up to approximately 15 meters above the North American Vertical Datum of 1988. The water-level time series were analyzed to provide estimates of tidal range (great diurnal range and mean range of tide), tidal datums (mean high water, mean higher high water, mean low water, and mean lower low water), and nuisance flooding (highest astronomical tide and monthly mean high water). The resulting data are provided at all points of the computational grid for Chesapeake and Delaware Bays and the surrounding coastal area.

Airborne magnetic and radiometric survey, Columbia, South Carolina and surrounds, 2020

This data release provides digital flight line data for a high-resolution airborne magnetic and radiometric survey over Columbia, South Carolina, and the surrounding region. The airborne data collection was funded by the U.S. Geological Survey (USGS) Earth Mapping Resource Initiative (Earth MRI) with goals of better understanding placer deposits containing critical mineral resources titanium, zirconium, and rare earth elements and of imaging the crystalline basement partly buried beneath Atlantic Coastal Plain sediments. The survey was flown northwest of and slightly overlapping an airborne magnetic and radiometric survey collected in 2019 (Shah, 2020).  The northwestern boundary of the 2020 survey lies within the metamorphic and igneous rocks of the Piedmont Province. Together, the 2019 and 2020 airborne surveys provide a transect across Atlantic Coastal Plain sediments from the Piedmont Province to the Atlantic Ocean.

Primary production and precipitation data along an elevation gradient in and adjacent to the San Francisco Mountains near Flagstaff, Arizona - 2015-2020

These data were compiled to allow further understanding of how aboveground net primary production of different plant functional types in ecosystems along an elevation gradient in the southwestern U.S. respond to extreme changes in warm-season precipitation (drought and water addition) associated with the North American Monsoon. The objectives of the study were to 1) determine how primary production responds to warm-season precipitation extremes over time; 2) compare production sensitivities to warm-season precipitation (slopes of production – precipitation relationships) across an elevation gradient; 3) evaluate whether the sensitivity of production differed under extreme dry and wet years compared to ambient precipitation. These data represent aboveground net primary production and associated warm-season (May - September) precipitation measurements from 2015 - 2020 during a precipitation manipulation experiment carried out across a desert scrubland, desert grassland, juniper savanna, ponderosa pine meadow, and mixed conifer meadow. These data were collected on or adjacent to the San Francisco Peaks near Flagstaff, Arizona by the U.S. Geological Survey using field measurements. These data can be used to better understand how production of different plant functional types respond to changes in warm-season precipitation in the aforementioned ecosystem types.

Remotely sensed fine fuel data for Buenos Aires National Wildlife Refuge (BANWR) from 2015 to 2020

These data were compiled to estimate fine-fuel abundance and distribution across the Buenos Aires National Wildlife Refuge in southern Arizona, USA.  The objectives of the study were to develop and validate annual estimates of fine fuel (biomass of herbaceous vegetation) for the refuge and to assess changes in fine fuels through time in response to wildfire and prescribed fire.  These data represent the amount of herbaceous biomass or fine fuels (kg/ha) present at a 10-m resolution derived from in-situ estimates of ground cover modeled with satellite imagery.  These satellite image data were collected over the Buenos Aires National Wildlife Refuge during leaf-on (August) and leaf-off (November) time periods annually from 2015-2020, by the European Space Agency's Sentinel-2A MSI.  In-situ field data were collected in the Buenos Aires National Wildlife Refuge from 2012-2015 by the U.S. Fish and Wildlife Service.  These data can be used to understand changes in fine fuel distribution through time and to assess impacts of wild and prescribed fire on fuel loads.

Uptake and bioaccumulation of per- and polyfluoroalkyl substances in fish in the Columbia Slough, Portland, Oregon: 2019-2020

The Columbia Slough is located south and parallel to the Columbia River in Portland, Oregon and consists of approximately 19 miles of predominantly urbanized waterway that drains approximately 32,700 acres of land with industrial, commercial, residential, and agricultural uses. Per- and polyfluoroalkyl substances (PFAS) are found in aqueous film forming foams (AFFF) used for firefighting, and soil and groundwater contamination by PFASs has been detected at Portland International Airport (PDX) and the adjacent Portland Air National Guard base (PANG). PFASs have also been detected in sediments from Columbia Slough, which receives stormwater runoff from both PDX and PANG. Fish tissue samples were collected from the Columbia Slough in July of 2019 and July of 2020 and analyzed for over 240 individual PFAS.

Yellowstone Sample Collection - database

This database was prepared using a combination of materials that include aerial photographs, topographic maps (1:24,000 and 1:250,000), field notes, and a sample catalog. Our goal was to translate sample collection site locations at Yellowstone National Park and surrounding areas into a GIS database. This was achieved by transferring site locations from aerial photographs and topographic maps into layers in ArcMap. Each field site is located based on field notes describing where a sample was collected. Locations were marked on the photograph or topographic map by a pinhole or dot, respectively, with the corresponding station or site numbers. Station and site numbers were then referenced in the notes to determine the appropriate prefix for the station. Each point on the aerial photograph or topographic map was relocated on the screen in ArcMap, on a digital topographic map, or an aerial photograph. Several samples are present in the field notes and in the catalog but do not correspond to an aerial photograph or could not be found on the topographic maps. These samples are marked with “No” under the LocationFound field and do not have a corresponding point in the SampleSites feature class. Each point represents a field station or collection site with information that was entered into an attributes table (explained in detail in the entity and attribute metadata sections). Tabular information on hand samples, thin sections, and mineral separates were entered by hand. The Samples table includes everything transferred from the paper records and relates to the other tables using the SampleID and to the SampleSites feature class using the SampleSite field.
