Data

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...

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 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.

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...

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...

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...

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...

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...

A global shapefile delineating prospectivity regions for seafloor massive sulfides (SMS), also known as polymetallic sulfides, was developed to identify seabed regions permissive for hydrothermal sulfide mineralization. The dataset classifies regions according to their relative prospectivity for SMS mineralization using geological and oceanographic parameters, including evidence of...

This revised dataset was created by the National Water Quality Laboratory (NWQL) in Lakewood, CO for the Wastewater Indicators (WWI) in filtered water by solid phase extraction, gas chromatography mass spectrometry (GCMS) method known as Lab Schedule 1433 and covers the dates from March 19, 2018 to August 9, 2022. All data for Lab Schedule 1433 are included from the listed date range and...

This presents the observational chronology of eruptions of Ahyi Seamount. Data include USGS information products released for these eruptions, a summary of plumes of discolored water noted in moderate to high resolution satellite imagery back to 1999, and hydroacoustic detections from the direction of Ahyi Seamount from the Wake Island hydrophone array back to 2015.

Summary: This Data Release contains surface deformation measurements resulting from the June 24, 2026, M7.2 and M7.5 Venezuela earthquakes (USGS, 2026). The earthquakes likely ruptured ~175-200 km of the Boconó and San Sebastián faults with right-lateral slip, but minimal discrete surface rupture has been identified to date. These data are based on rapid analysis of available satellite...
