Data

This data set includes the magnetotelluric (MT) 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 audiomagnetotelluric (AMT) surveys, in the Rio Grande rift to improve understanding of the hydrogeology of the Santa Fe Group and the nature of the sedimentary deposits...

Charcoal counts and soil, water, and reservoir sediment-core geochemistry were characterized eight months after the November 2021 Muckamuck Fire in the North Fork Salmon Creek basin and Conconully Reservoir, Washington, the receiving water body. Parameters include sand-sized charcoal, Cesium-137, excess Lead-210, aqueous and solid-phase elemental chemistry, and polycyclic aromatic...

Geochemical and mineralogical data were collected for samples of the Devonian Marcellus Shale, as well as overlying and underlying units in the Enerplus Snow Shoe 4-8HG core. The data was integrated with well logs in a manuscript that focuses on the estimation of original organic richness (total organic carbon content) in thermally mature petroleum source rocks. This data release...

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...
