Luminescence data associated with depositional timing and fluvial strath terrace abandonment with multiple chronometers near the Stinking Springs fault in southwestern Colorado Luminescence data associated with 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...
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...
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...
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...
Surveying Southern Lake Ontario Embayments For The Presence Of Cisco 2015-2021 Surveying Southern Lake Ontario Embayments For The Presence Of Cisco 2015-2021
Individual gill net collection sites for fish community assemblage including Cisco in Southern Lake Ontario Embayments were recorded. Fish community assemblages including Cisco was assessed using multi-panel gill nets fished overnight to determine where Cisco were residing. Total fish community was recorded with observational recording of fish species, fish total length (mm), and water...
Genesee River Lake Sturgeon (Acipenser fulvescens) Capture Data (2016-2025) Genesee River Lake Sturgeon (Acipenser fulvescens) Capture Data (2016-2025)
Since 2003, an ongoing research project has been conducted in the Genesee River, New York regarding lake sturgeon reintroduction techniques. This project's applied technique involved the release of age-0 hatchery reared juveniles into historic tributary habitat. One goal of this long-term reintroduction project was to document the return of adult lake sturgeon for spawning after more...
Hydrus-1D simulations of vertical water and chloride fluxes in shallow soils near breccia pipe uranium mines, Mojave County, Arizona Hydrus-1D simulations of vertical water and chloride fluxes in shallow soils near breccia pipe uranium mines, Mojave County, Arizona
A study was conducted of mixed-metal transport of dissolved versus solid phases in shallow soils at four semi-arid, breccia-pipe uranium mine sites in Mojave County, Arizona. As a part of that study, multi-decadal Hydrus-1D models (Šimůnek and others, 2009) were applied at each site to evaluate the potential for downward movement of water. A one-dimensional vertical profile of the...
