Geochemistry and High-Resolution Backscattered Electron Imaging of Meteor Crater Impact Melts
Utilizing the USGS Meteor Crater Sample Collection, we sampled impact melt particles for geochemical and textural characterization using a scanning electron microscope and electron microprobe. Samples were collected from a range of different depths and distances from the crater rim, all within the proximal ejecta blanket. By using the Meteor Crater Sample Collection, in which all samples have know
Streambank topographic lidar survey of the French Broad River near the Interstate 26 bridge located south of Asheville, NC – November 2019, Pre-construction

Geochemical data for the Pacheco stage tephra-fall deposits from Misti volcano, Arequipa, Peru
These data are derived from pumice and scoria from Pacheco stage (as defined by Harpel et al., 2021) tephra-fall deposits (TFD) emplaced between
Predicted consequences of detecting Najas minor environmental DNA in Sebago Lake Maine, 2022
U.S. Geological Survey decision analysts and technical experts worked with managers and stakeholders to predict the consequences of alternative actions following environmental DNA detections of invasive Najas minor eDNA in Sebago Lake, Maine, USA. This dataset provides the consequence and model inputs for each of the alternative actions under different levels of uncertainty.
Upper Klamath Lake and Clear Lake sampling for suckers from 2015 through 2022

Geochemical data for water, sediment, and biota in areas affected by historical mining, northwestern Sierra Nevada and Trinity Mountains, California
This dataset includes data for water, sediment, and biota samples collected at 250 locations in the northwestern Sierra Nevada and the Trinity Mountains during 1999–2012. The locations were chosen to assess potential effects from historical mining, with a focus primarily on mercury contamination associated with placer gold mines in the Sierra Nevada and the Trinity Mountains, and a hard-rock mercu
Model Archival Summary for Suspended-Sediment Concentration at U.S. Geological Survey Site 06887000, Big Blue River near Manhattan, Kansas, during July 2018 through August 2023
This model archival summary summarizes the suspended-sediment concentration (SSC; U.S. Geological Survey [USGS] parameter code 80154) model developed to compute 15-minute, hourly, or daily SSC from July 26, 2018, onward. This model is specific to USGS site 06887000, the Big Blue River near Manhattan, Kansas, during this study period and cannot be applied to data collected from other locations on t
Root and Shoot Lengths of Rice and Bermuda Grass Seedlings Inoculated with Endophytic Bacteria from Phragmites australis
