The size and distribution of riverbed grain size plays a foundational role in river morphology and ecology. This study (White and others, 2025) quantifies submerged riverbed grain size at high resolution (1 square meter) across 260 kilometers of geomorphically diverse river corridors in the Santiam River Basin, Oregon, by pairing bathymetric lidar point-clouds collected in 2023 with...

This data release presents point data associated with studies to understand the crustal structure of the 2019 Ridgecrest earthquakes epicentral region and the interaction of the northeast-to-east-striking Garlock fault with the northwest-striking faults of the Eastern California Shear Zone and Walker Lane. Data include principal fact information for new gravity measurements collected by...

This data set includes the audio-magnetotelluric (AMT) sounding data collected from 1997 to 2004 in and near the Rio Grande rift, New Mexico. The U.S. Geological Survey conducted a series of multidisciplinary studies, including magnetotelluric surveys, in the Rio Grande rift to improve understanding of the hydrogeology of the Santa Fe Group and the nature of the sedimentary deposits...

The 3D Elevation Program (3DEP) is managed by the U.S. Geological Survey (USGS) National Geospatial Program to respond to growing needs for high-quality topographic data and for a wide range of other three-dimensional (3D) representations of the Nation's natural and constructed features. 3DEP informs critical decisions that are made across our Nation every day that depend on elevation...

Samples were collected for a comparison method development study with the University of Minnesota and the U.S. Geological Survey (USGS) National Water Quality Laboratory (NWQL) in Lakewood, Colorado. Widely used liquid chromatography-tandem mass spectrometry (LC-MS/MS) methods fail to capture large fractions of total organofluorine in environmental samples confounding the assessment and...

This study evaluated three sedation methods to determine their efficacy for use during telemetry tagging. Five fish species (bighead carp, grass carp, bigmouth buffalo, American paddlefish, and lake sturgeon) were sedated using eugenol (AQUI-S® 20E), dissolved carbon dioxide, and electroanesthesia to determine sedation induction times. After sedation, half of the fish from each treatment...

This dataset contains geochemical, isotopic, and biomarker data derived from sediment cores collected in Siskiwit Bay, Lake Superior, Wisconsin, USA. The dataset supports the reconstruction of historical phytoplankton communities, including cyanobacterial blooms, and environmental conditions over the past ~5,400 years. Measurements include carotenoid and chlorophyll pigments (via high...

This data release provides aerial images acquired through the National Agricultural Imagery Program (NAIP) used to test a method for inferring image acquisition time from shadow orientation. For many applications, such as linking remotely sensed data to streamflow recorded at a gaging station, knowing the time an image is acquired is important, but such metadata often is not available...

We conducted nineteen acute toxicity assays to address knowledge gaps associated with nine critical elements: cerium (Ce), cobalt (Co), indium (In), lanthanum (La), lithium (Li), neodymium (Nd), osmium (Os), platinum (Pt), and praseodymium (Pr). Acute aquatic exposures of these elements were conducted with five organisms: an amphipod (Hyalella azteca), a mussel (Lampsilis siliquoidea), a...

This dataset, prepared by the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC), provides beach profile data collected at Dorado, Puerto Rico. Data were collected from 2022-2024 on foot by a person equipped with a Global Navigation Satellite System (GNSS) receiver and antenna affixed to a backpack outfitted for surveying location and elevation data...

Marine Corps Base (MCB) Camp Pendleton is an approximately 125,000 acre facility located in coastal southern California between the Los Angeles and San Diego metropolises. Established in 1942, historical military activities on the MCB Camp Pendleton have resulted in the release of environmental contaminants at numerous sites. To mitigate the risk to human health and the environment at...

This data release contains grids, in geographic tagged imaged file (.tif) format, summarizing inundation frequency of the U. S. Geological Survey (USGS) Dynamic Surface Water Extent (DSWE) Landsat Science Product at 114 National Wildlife Refuges throughout the U.S. Fish and Wildlife Service (USFWS) Mountain-Prairie Region (Colorado, Kansas, Montana, Nebraska, North Dakota, South Dakota...
