Data

Understanding the eruptive histories and petrogenetic models that underpin hazard assessments at active volcanoes typically requires high-precision ages for late Pleistocene to Holocene lava flows. These data vary in quality, typically related to textural and chemical variations in lava flow samples. These samples were part of an existing 40Ar/39Ar dataset for andesitic-dacitic rocks...

We developed numerous datasets describing mining activity and landscape conditions for all known active, inactive, abandoned, and legacy surface mines in the Eastern United States Appalachian region to support monitoring and regulatory needs. These data include 1) a study area boundary, 2) a compiled set of spatial footprints for known mines from federal, state, academic research, and...

Fathead minnows (Pimephales promelas) exposures to water containing per- and polyfluoroalkyl compounds (PFAS) related to aqueous film-forming foam used in extinguishing fires were performed on-site at the USGS Toxic Substance Hydrology Groundwater Research Site on Cape Cod, MA. In 2019, to investigate potential effects on reproductive parameters, exposures were performed for either 7 or...

Laboratory data were collected in 2021 on live fathead minnow sperm motilities by using computer assisted sperm motion analysis. Flow cytometry data were collected on the testicular cells; data are in standard format that allows files created by one type of acquisition hardware and software to be analyzed by any other type. This study on potential reproductive effects was performed in...

This study aimed to determine movement patterns of Mooneye in the St. Croix National Scenic Riverway (SACN) to better understand their range, seasonal behavior, spawning site fidelity, and co-occurrence with Spectaclecase. To our knowledge, Mooneye have never been tracked with acoustic transmitters. Prior to Mooneye trials, we conducted a Gizzard Shad pilot to ensure surgeries were...

The U.S. Geological Survey and a consortium of local governments in North Carolina have partnered together to track water quality and quantity conditions in several of the area’s water-supply reservoirs and streams, known as the Triangle Area Water Supply Monitoring Project (TAWSMP). This data release contains the associated data described in the Open-File Report, "Triangle Area Water...

To support floodplain forest research and management actions on the Upper Mississippi River System (UMRS), areas of forest loss, gain and persistence at least 0.1 hectare in size from 2010 to 2020 were mapped and analyzed. This forest cover transition data will allow researchers the ability to examine rates and patterns of forest cover loss, gain, and persistence and compare multiple...

This data release contains the TVSWA_Delineator tool, and the associated groundwater-flow and particle-tracking model files used to define source water assessment areas for public water supply wells in the Treasure Valley. It includes a Python-based executable utilizing the FloPy package, specialized MODPATH 7 particle-tracking configurations, and a modified version of the MODFLOW 6...

These data describe counts of bird species, descriptions of their spatial and temporal locations from the observer, and their breeding behaviors. The data were collected between May and July of 2023, 2024 and 2025 by 5 individual observers. The observers also collected data on the date and time of observations, the weather conditions, and other variables influencing the detection of...

The provided 2021 Utah Integrated Monitoring of Bird Conservation Regions (IMBCR) dataset contains avian detection data for each of three bird species (downy woodpecker, olive-sided flycatcher, yellow warbler) breeding in Utah, USA considered in the related manuscript. Data were collected by IMBCR partners during the breeding season from stratified survey grid locations. Each survey grid...

This dataset contains discharge measurements derived from acoustic Doppler current profiler (ADCP) observations collected at U.S. Geological Survey (USGS) stream gage locations that are observable by the Surface Water and Ocean Topography (SWOT) satellite. ADCP measurements were compiled for the period 2015 through December 1, 2025 and paired with reach-scale median SWOT-observed water...

This dataset contains level, temperature, and conductivity data collected by scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC) to investigate submarine groundwater discharge on the West Florida Shelf at sample sites located in three areas of Florida: Indian Rocks Beach (IRB), Nature Coast near Hudson (NC), and Venice Headlands...
