This data release contains the spatial raster outputs, R code, and lookup table from a synthesis of U.S. Forest Service Activity Tracking System (FACTS) vegetation management activities hypothesized to influence bat habitat. The included raster data cover the continental United States and represent the number of years that have passed since a given management action was implemented...

This dataset includes information from a yellow perch (Perca flavescens) tagging experiment, where the goal was to evaluate tag retention rates, and impact of tagging on growth, condition, and survival. Fish were held in a recirculating aquaculture system (RAS) over a 168-day period to evaluate four external tag types including loop, ring, streamer, and T-bar anchor tags. Data were...

This data release presents optically stimulated luminescence (OSL) and infrared stimulated luminescence (IRSL) measurements from sediment samples collected at Quaternary fault exposures in central and southeastern Washington. The primary focus of the dataset is luminescence data from three paleoseismic trenches excavated across the Dead Coyote fault scarp in the Kittitas Valley, central...

This data release contains 54 (U-Th)/He dates acquired from detrital magnetite in stream sediments adjacent to the Taurus Porphyry Cu-Mo(-Au) deposit in eastern interior Alaska's Yukon-Tanana Upland. Measured parameters include Helium-4, Uranium-238, Thorium-232, measured grain geometry factors, and all associated analytical uncertainties. Final (U-Th)/He dates along with uncertainties...

This data release documents movement of the toe of Cleveland Corral Landslide, El Dorado County, CA from October 1, 2016, to September 30, 2017, based on GPS data from near real-time monitoring. Raw GPS data from L1-only receivers were recorded in 15 second epochs using data acquisition systems and radio telemetry developed by the USGS Volcano Hazards Program. The overall system, named...

This data release includes sampling location data, the information about sequenced organisms and the SRA accession number for the 16S whole-organism sequencing data for larval aquatic insects, emergent adult insects, and two riparian spiders from Torch Lake and Gratiot Lake (N=3 sites at each Lake). Torch Lake (Houghton County, Keweenaw Peninsula, Michigan, USA) is a Great Lakes Area of...

The survey was conducted to assess the distribution of terrapins in the Chesapeake Bay, based on evidence related to nesting. We conducted a survey of the beaches during the nesting season in the summer of 2002. We walked along the shoreline of over 1350 beach segments looking for evidence signifying the presence of terrapins based on nesting activity. These results represent a single...

Wildfire can substantially alter the hydrologic response of watersheds to rainfall, and debris-flow activity is among the most destructive consequences of these events. To assist federal, state, and local agencies in planning for postfire hazards, the U.S. Geological Survey conducts debris-flow hazard assessments for recent wildfires. This collection holds all postfire debris-flow hazard

The U.S. Environmental Protection Agency (EPA) National Coastal Condition Assessment (NCCA) is a nationwide survey of coastal and estuarine water quality. During the 2015 EPA NCCA, samples were collected at 732 sites for analysis of algal toxins and cyanotoxins at the Organic Geochemistry Research Laboratory (OGRL) at the U.S. Geological Survey Kansas Water Science Center (KSWSC) by...

The EPA National Coastal Condition Assessment (NCCA) is a nation-wide survey of coastal and estuarine water quality. During the 2015 EPA NCCA, samples were collected for analysis of algal toxins and cyanotoxins at the Organic Geochemistry Research Laboratory (OGRL) at the U.S. Geological Survey Kansas Water Science Center (KSWSC) by liquid chromatography triple quadrupole mass...

U.S. Geological Survey (USGS) scientists conducted field data collection efforts between September 30th and October 9th, 2021 over a large stretch of the Potomac River in Maryland and West Virginia using high accuracy surveying technologies. The work was initiated as an effort to validate commercially acquired topobathymetric light detection and ranging (lidar) data that was collected

This dataset represents field data from a multi-year experiment testing the cut-to-drown management strategy in patches of Phragmites australis at two sites in the Great Lakes coastal zone. We established research plots where Phragmites was cut under the water to test that treatment's effectiveness as a control strategy. The experiment took place in 2022 and 2023. Over the multi-year...
