This data release contains data collected during August 2020 for the post Carr fire Bioassessment project at Whiskeytown National Recreation Area, Shasta County, California. Data includes sediment and habitat characteristics, water chemistry, and biological conditions of tributaries to Whiskeytown Lake and Clear Creek below the dam. Samples were also collected to assess concentrations of...

In October 2017, the Atlas, Nuns, and Tubbs wildfires in Napa and Sonoma Counties, CA burned approximately 133 thousand acres. Multiple watersheds were affected by the fires, with up to 95% of some watersheds being burned. Post-fire assessments were conducted at 10 sites within Napa and Sonoma Counties to assess the effects of fire on sediment, water quality, and ecology. This data...

This dataset includes 2022 reach fish data and reach habitat data collected to support development of the upper Santa Ana River Habitat Conservation Plan for the Santa Ana Sucker (Catostomus santaanae) and the Arroyo Chub (Gila orcutti) in the Santa Ana River, California.

A multiresidue method for solids (i.e., soil, sediment, sludge) was developed and evaluated for the analysis of pesticides and pesticide degradates. Initially, a well characterized soil was used to determine the recovery of target compounds using an Energized Dispersive Guided Extraction (EDGE) system with two extraction solvents, acetonitrile and 1:1 (v/v) hexane:acetone. Extracts were...

This data set includes count, location, and ancillary habitat data for fishes sampled in adjacent reaches of Georgiana Slough, Sacramento River, and Steamboat Slough in the northern Sacramento-San Joaquin Delta. It also includes data on the stomach contents of selected individual black basses (Micropterus). Fishes were sampled by boat electrofishing from approximately January-May, 2020...

This release presents provisional volcanic gas monitoring data from multi-GAS (multiple Gas Analyzer System) station "YELL_MUD", installed in July 2021 in the Obsidian Pool thermal area, Yellowstone National Park, USA. The multi-GAS station includes gas sensors to measure water vapor, carbon dioxide (CO2), sulfur dioxide (SO2), and hydrogen sulfide (H2S) in gas plumes, as well as...

In 2010, the U.S. Environmental Protection Agency, Region 10, initiated the Puget Sound Scientific Studies and Technical Investigations Assistance Program, which was designed to support research for implementing the Puget Sound Action Agenda. The Action Agenda was created because Puget Sound was designated as one of 28 estuaries of National Significance under section 320 of the Clean...

This data set was compiled for the Suwannee River Water Management District for use in determining Minimum Flows and Levels. The data set contains detection summaries of acoustically tagged adult Gulf sturgeon using the Upper Suwannee River areas equipped with Innovasea Vemco acoustic receivers (2011-2019).

The USGS, in cooperation with the U.S. Bureau of Land Management (BLM), created a series of geospatial products of the South Cow Mountain Recreational Area, Lake County, California, using historic aerial imagery and structure-from-motion (SfM) photogrammetry methods. Products were generated from stereo historical aerial imagery acquired by the BLM in May of 1977. The aerial imagery were...

This vector geospatial dataset contains bounding polygons that visualize the domain of archived groundwater flow models published by the Upper Midwest Water Science Center and attributes pertaining to the associated publication (citation, year of publication, authors, report ID, publication URL), model construction details, and a URL for publicly available model archives when available...

Multichannel seismic reflection data were collected by the U.S. Geological Survey in May of 2015 outside of Palma Bay, Alaska. Seismic data were acquired coincidentally with high resolution bathymetry (Dartnell and others, 2022). Data were acquired to map the offshore extension of the Queen Charlotte-Fairweather Fault. The fault has produced several significant earthquakes during the...

The Middle Pennsylvanian (Bolsovian) Leatherwood coal in central eastern Kentucky is a moderately thick (up to >1.6 m in the sites examined in this study) coal bed that has been one of the major sources of electricity in the region. To document and understand the organic petrology and inorganic chemistry of the Leatherwood coal, geologists from the University of Kentucky Center for...
