Data

We synthesized existing literature to develop this dataset which relates suspended sediment concentration and exposure duration to biological effects on fishes. Our dataset contains a total of 3,610 dose-response data triplicates consisting of (a) suspended sediment concentration, (b) duration of exposure, and (c) fish severity of ill effects (SEV). There is no original data in the...

Concentrations of individual polychlorinated biphenyl (PCB) congeners, polycyclic aromatic hydrocarbons (PAHs), and chlorinated pesticides are reported for surface sediments collected along the nearshore of Bellingham Bay, the Nooksack River, and four urban creeks discharging to Bellingham Bay in March 2019. Additional samples were collected along the nearshore urban waterfront corridor...

This data release contains information on four sediment cores that were collected by the U.S. Geological Survey in Conconully Reservoir, Okanogan County, Washington, in June 2022 and October 2023. Data include the location each sediment core was collected, descriptions of the sediment profile of two of the cores (i.e., texture, color, structure, and visible constituents), photographs of...

This data release contains sediment core data including X-ray Computed Tomography (CT) scans, photos, and multi-sensor core logger (MSCL) data. Sediment cores were collected along the Cascadia Subduction Zone (offshore northern California, Oregon and Washington) during U.S. Geological Survey cruise 2022-653-FA aboard the M/V Bold-Horizon. The cores were collected to evaluate potential...

Data shows radioisotope measurements (Pb-210 and Cs-137) of sediment cores from four coastal wetlands along the Chesapeake Bay (one core from each site). Cores were sectioned every 1-2 cm depth.

In 2023, scientists from the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center (USGS SPCMSC) conducted a sediment sampling survey at the northern Chandeleur Islands, Louisiana. Funded by the Extending Government Funding and Delivering Emergency Assistance Act (Public Law 117-43) enacted on September 30, 2021, these data complement sediment data from samples...

This data release supersedes version 2.0, published in September 2023 at https://doi.org/10.5066/P9MAJHNI. Versioning details are documented in the accompanying Klamath_estuary_sediment_grain_size_VersionHistory.txt. This data release includes grain-size measurements on sediment samples collected from the substrate surface and uppermost 10 cm of sediment deposits in the Klamath River...

The collection and analysis of fluvial sediment samples has been an integral part of hydrologic studies in the United States for over 125 years (Gordon and others, 2000). Accurate measurement of sediment concentrations and its movement in streams is critical to maintaining important infrastructure and habitats in the Nation’s waterways, such as impoundments and estuaries (Hudson and...

Dataset of sediment macrofaunal communities, geochemistry, and grain size associated with chemosynthetic and soft-sediment habitats along the Cascadia margin, Pacific Ocean, in 2019.

This data release presents organic geochemical data collected from sediments within the Escanaba Trough, a sedimented hydrothermal spreading center within the U.S. EEZ off the coast of Northern CA which contains marine minerals (USGS Field Activity 2022-621-FA). The data includes total organic carbon and total nitrogen content, stable and radioisotopes, compound specific biomarker data...

This data release contains results from the analysis of streambank and adjacent hillslope sediment samples collected from the Stony Clove and Woodland Creek watersheds in the Catskill Mountain region of New York State from July to October 2024. Fourteen or fifteen samples were collected from each of three depositional units ­­— alluvium, glaciolacustrine clay, and glacial till. Results...

The U.S. Geological Survey, in collaboration with seismologists from University of Kentucky, performed a 917-meter east-west oriented shear horizontal (SH)-wave seismic-reflection survey in the Wabash Valley Seismic Zone in southeastern Illinois. The resulting profile, named ML-2, images the near-surface geology underlying the Meadow Bank scarp, a roughly 10-km long northeast-oriented...
