Data

This data release contains peak-flow frequency analyses for selected streamgages in Lincoln County, Montana, along with information documenting the input data and specifications for the analyses. The analyses were performed using the methods described by Siefken and others (2025).

These datasets support the conclusions in the journal article entitled "Population vulnerability of residents, employees, and cruise-ship passengers to tsunami hazards in complex seismic regions: a case study of the U.S. Virgin Islands" as described in the abstract below: Reducing the potential for loss of life from tsunamis is challenging on islands located in complex seismic regions...

This data set describes the genomic bacterial analysis of swabs and tissues collected from whooping cranes in Louisiana. The data includes targeted analysis from quantitative PCR for bacterial pathogens.

Caves preserve useful archives of fluvial sediments, especially in mountainous landscapes that hinder the preservation of thick, dateable terrace deposits. We used cosmogenic ²⁶Al and ¹⁰Be to date the burial of sediments in four caves along tributaries of the New River: Windy Mouth Cave along the Greenbrier River in West Virginia, Haynes Cave along Second Creek in West Virginia, Bone...

This U.S. Geological Survey (USGS) Data Release provides a digital geospatial database for the Bedrock geology of the Evitts Creek and Patterson Creek quadrangles, Maryland, Pennsylvania, and West Virginia from the original map of de Witt and Colton, 1964. Attribute tables and geospatial features (points, lines, and polygons) conform to the Geologic Map Schema (GeMS, 2020) and represent...

Defining a realized niche using key habitat components like temperature, water clarity, and dissolved oxygen (DO) is important to understanding how distributions and demographics of freshwater fish populations may respond to environmental changes. However, habitat preferences are often defined in a laboratory setting and may not accurately reflect preferred habitat in nature. To define a...

This data release contains acoustic Doppler current profiler (ADCP) data collected in 2023 from two uplooking tripods in bays of Lake Ontario in Central New York. Data were collected at Irondequoit Bay (USGS station number 431314077315901) and at Sodus Bay (USGS station number 431533076582101). Data are organized by bay in child item datasets containing the raw binary data files from the...

The dataset contains spectral indices values calculated from Landsat imagery, normalized difference vegetation index (NDVI) and delta normalized burn ratio (NBR, deltaNBR). The spectral indices were computed for 1472 forested sites in the Glacier National Park, Montana, over the 1984-2021 period, in areas that were burned or not burned during the Robert Fire of 2003.

In July 2022, the U.S. Geological Survey (USGS) and the University of Maryland's Chesapeake Biological Laboratory conducted a study, USGS Field Activity Number (FAN) 2022-020-FA, in Chesapeake Bay to quantify greenhouse gas fluxes from the largest estuary in the United States. The team investigated the environmental factors that control the distribution and exchange of methane and carbon...

This data release contains elemental concentration data from geochemical analysis of eight bulk placer tailing sediment samples and of size and density fractions derived from those eight samples. All placer tailing material collected for this data release originated from samples that were collected in Alaska. The samples collected from one fifth yard of tailings material, sieved to -1/4...

These data were collected using distance sampling methods (point counts) and visual assessment of land cover and habitat along pre-determined driving routes in Texas during April and May 2016.

Autonomous recording units are increasingly being used to monitor wildlife on large geographic and temporal scales, paired with machine learning (ML) to automate detection of wildlife. However, false positive detections from ML classifiers can result in erroneous ecological models that can lead to misguided management and conservation actions. We used a two-stage general approach to...
