Future coastal hazards along the U.S. Atlantic coast
This product consists of several datasets that map future coastal flooding and erosion hazards due to sea level rise (SLR) and storms for three States (Florida, Georgia, and Virginia) along the Atlantic coast of the United States. The SLR scenarios encompass a plausible range of projections by 2100 based on the best available science and with enough resolution to support a suite of different plann
Chesapeake Bay Land Use and Land Cover (LULC) Database 2022 Edition
The Chesapeake Bay Land Use and Land Cover Database (LULC) facilitates characterization of the landscape and land change for and between discrete time periods. The database was developed by the University of Vermont’s Spatial Analysis Laboratory in cooperation with Chesapeake Conservancy (CC) and U.S. Geological Survey (USGS) as part of a 6-year Cooperative Agreement between Chesapeake Conservancy
Post Carr Fire Bioassessment Data, Whiskeytown National Recreation Area, Shasta County, California, 2020
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 metals in
Post-Fire Stream Assessment Data, Napa and Sonoma County, California, 2017-2018
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 release contain
Santa Ana River Native Fish Population and Habitat Data, Santa Ana River, California, 2022
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.
Multiresidue extraction of current-use pesticides from complex solid matrices using energized dispersive extraction with analysis by gas and liquid chromatography tandem mass spectroscopy
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 cleaned us
Distribution and stomach contents of fishes in the northern Sacramento-San Joaquin Delta, 2020-2022
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, 2020-2022, plus
Provisional Multi-GAS Volcanic Gas Monitoring Data, Obsidian Pool thermal area, Yellowstone National Park
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 meteorologic para
Multibeam echo sounder, video observation, and derived benthic habitat data offshore of Tacoma, Washington
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 Water Act, an
Data release to Suwannee River Water Management District: Gulf Sturgeon Upper Suwannee River movements (2011-2019)
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).
Point cloud, digital surface model (DSM), and orthoimagery derived from historical aerial imagery of the South Cow Mountain Recreational Area, Lake County, California, May 27, 1977
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 downloaded
