Deer mouse distribution in the Wyoming Basins Ecoregional Assessment area Deer mouse distribution in the Wyoming Basins Ecoregional Assessment area
Map of deer mouse distribution developed from a probability of occurrence map created using multi-scale vegetation, abiotic, and anthropogenic features.
Geodetic polygons for an Alaska-Aleutian subduction zone interface earthquake recurrence model Geodetic polygons for an Alaska-Aleutian subduction zone interface earthquake recurrence model
This dataset represents polygons used to approximate areas of geodetic coupling for use in the 2023 update of the USGS National Seismic Hazard Model for Alaska.
Sediment properties, charcoal counts, and radiocarbon dates from the Frazier Mountain paleoseismic site, California Sediment properties, charcoal counts, and radiocarbon dates from the Frazier Mountain paleoseismic site, California
This data release provides geochemical, sedimentological, and geochronological data from interbedded mudflow and marsh deposits from the Frazier Mountain paleoseismic site, California (34.81232°, -118.9034°). The samples were collected to support paleoenvironmental reconstruction of the site and refine several previous investigations of paleoearthquakes along the San Andreas Fault...
Luminescence data for "Refining depositional timing and fluvial strath terrace abandonment with multiple chronometers near the Stinking Springs fault in southwestern Colorado" Luminescence data for "Refining depositional timing and fluvial strath terrace abandonment with multiple chronometers near the Stinking Springs fault in southwestern Colorado"
This data release contains data associated with six infrared stimulated luminescence samples collected to investigate strath terraces along Dutton Creek, near Pagosa Springs, Colorado. The terraces are capped with loess deposits and glacial outwash derived from Fourmile Creek at the edge of the San Juan Mountains. Results reveal evidence for the Bull Lake glaciation and outwash likely...
Geochronological Data for: Age and recurrence of paleoseismic surface faulting at the Dry Canyon trench site, northern Red Rock fault, Red Rock Valley, southwestern Montana Geochronological Data for: Age and recurrence of paleoseismic surface faulting at the Dry Canyon trench site, northern Red Rock fault, Red Rock Valley, southwestern Montana
Prominent scarps across alluvial fans along the northeast Tendoy Mountains in southwest Montana are evidence of late Quaternary surface ruptures on the 34 km-long Red Rock fault. Previous evaluations of the fault scarp characteristics, the distribution and ages of hanging wall alluvial fans, and the attributes of footwall drainage basins led to subdivision of the Red Rock fault into two...
Data for the development of methods for continuous monitoring of fluorescence of dissolved organic matter in karst groundwater of the Edwards aquifer, south-central Texas, 2019–24 Data for the development of methods for continuous monitoring of fluorescence of dissolved organic matter in karst groundwater of the Edwards aquifer, south-central Texas, 2019–24
Widespread urbanization across the Edwards aquifer recharge zone in south-central Texas has prompted the development of new approaches and tools to evaluate current and future groundwater quality. To support sustainable water supply and healthy ecosystems, long-term assessments and the integration of new technologies are essential for understanding spatial and temporal changes in aquifer...
Inventory of Shorebirds and other Bird Species in the Upper Cook Inlet Region of Alaska, 1996 and 1998 Inventory of Shorebirds and other Bird Species in the Upper Cook Inlet Region of Alaska, 1996 and 1998
This data release contains tabular data pertaining to population surveys of shorebirds, predatory birds (i.e., raptors, cranes, and gulls), and other bird species (i.e., passerines) conducted across the Upper Cook Inlet region of Alaska during 1996 and 1998. The data package includes five tables: 1) characteristics of bird survey sites including environmental conditions and habitat...
Annotated images of dreissenid mussels (Dreissena spp.) in down-looking color images in Lake Michigan, USA, to support machine learning modeling Annotated images of dreissenid mussels (Dreissena spp.) in down-looking color images in Lake Michigan, USA, to support machine learning modeling
This dataset is comprised of lakebed photographs collected by an autonomous underwater vehicle (AUV) in Lake Michigan, USA. Photos were annotated to identify invasive dreissenid mussels (Zebra and Quagga mussels) for use in machine learning and algorithm development, specifically to train and validate a transformer-based segmentation model (MusselFinder) for automated mussel density...
Assessment of sperm motility, apoptosis, and viability of Fathead Minnows (Pimephales promelas) exposed to polyfluorinated alkyl substances (PFAS) at Cape Cod, MA in 2024 Assessment of sperm motility, apoptosis, and viability of Fathead Minnows (Pimephales promelas) exposed to polyfluorinated alkyl substances (PFAS) at Cape Cod, MA in 2024
Adult male Fathead Minnows (Pimephales promelas) were exposed to water containing per- and polyfluoroalkyl compounds (PFAS) derived from aqueous film-forming foam in mobile laboratories on location at the USGS Toxic Substance Hydrology Groundwater Research Site on Cape Cod, MA. In 2024, to investigate potential effects on male reproductive parameters, two groundwater wells, including one...
Seed banks of invasive species of the Lower Mississippi River Delta Seed banks of invasive species of the Lower Mississippi River Delta
Seed banks were collected in freshwater wetlands of the Lower Mississippi River Delta with previous populations of the invasive Lythrum salicaria. Cyperus difformis was one other invasive species was found in the seedbank.
Geochemical data from coal and coal ash collected in Northern Vietnam, 2023 Geochemical data from coal and coal ash collected in Northern Vietnam, 2023
Coal and its combustion products (ash) are of interest as potential unconventional sources of critical minerals, particularly rare earth elements (REE). Vietnam has large coal reserves and employs coal-fired power plants to generate more electricity than any other energy source. Because there are limited data available on the REE content of coal and coal combustion products from Vietnam...
Hatchery-origin Atlantic Salmon Acoustic Telemetry Tag Detections from the St. Regis and St. Lawrence Rivers, 2022-2025 Hatchery-origin Atlantic Salmon Acoustic Telemetry Tag Detections from the St. Regis and St. Lawrence Rivers, 2022-2025
This data release includes hatchery-origin juvenile Atlantic Salmon (age-1) acoustic telemetry tag detections from the St. Regis and St. Lawrence Rivers in association with a project to experimentally stock Atlantic salmon within the Lake Ontario watershed. Age-1 fish were surgically implanted with Innovasea V9T model acoustic telemetry tags and released in the Spring of 2022, 2023, and...
