To understand water scarcity issues in the Upper Colorado River Basin (UCRB), our research team collaborated with librarians at the Department of Interior with access to Lexis Nexis to query its newspaper and congressional research databases for topics of interest between 2000 and 2024 in our area of interest in the UCRB. The data were pre-processed into a tabular format and loaded into...

Aerial photography surveys of Redoubt Volcano in Lake Clark National Park, Alaska, were conducted on August 8 and September 26, 2019, by fixed-wing aircraft to generate updated elevation data and high-quality orthoimagery. The surveys were flown by the National Park Service (NPS) Alaska Regional Office (AKRO) in partnership with the United States Geological Survey (USGS) Alaska Volcano...

The data were collected as part of a study using underwater cameras to describe fish habitat preferences under the ice in four backwaters located in Pools 7 and 8 on the Upper Mississippi River. The dataset contains both environmental data and fish abundance data. The environmental data were collected at each site to describe the conditions and water quality at the time of sampling. The...

The Great Lakes Fishery Commission sea lamprey program is concerned with the risk of lampricide applications to non-target animals, especially those of conservation concern. Conneaut Creek (Ohio and Pennsylvania) is routinely treated for larval sea lampreys (Petromyzon marinus) and contains a population of salamander mussels, which has been proposed for listing as federally endangered by...

The Upper Cement Creek watershed in southwestern Colorado hosts extensive acid mine drainage and naturally occurring acid rock drainage. Between 2022 and 2024, the U.S. Geological Survey (USGS), in cooperation with the U.S. Environmental Protection Agency, completed synoptic tracer-injection studies and monitored water temperatures in order to evaluate spatial and temporal changes in...

(2026) "Development of Liquefaction-Targeted Design Basis in U.S. Seismic Provisions". Earthquake Spectra. https://doi.org/10.1002/esp4.70097. This dataset includes tabular data summarizing effective 50-year non

Much of the southeastern United States, including all of Florida, is covered by flat-lying sedimentary strata of the Atlantic and Gulf Coastal Plains which have accumulated since Middle Jurassic time. The pre-Middle Jurassic rocks that underlie these coastal plains in Florida, here collectively referred to as “basement,” are known only from a relatively small number of boreholes. This...

The Network for Observation of Volcanic and Atmospheric Change (NOVAC) is a community of volcano observatories and research institutions that together develop and apply ultraviolet differential optical absorption spectroscopy (DOAS) instruments to measure volcanic gas emission rates. The collected data are used for assessment of volcanic activity, eruption forecasting, research on...

This data product consists of a database of population change and abundance estimates for North American birds, estimated from North American Breeding Bird Survey (BBS) data. Data are presented for 545 species (or groups of species) of birds in five spreadsheets containing trend estimates for three time periods and annual indices for two time periods. Estimates are derived for each...

Tools that accurately and reliably forecast potential ecological responses to both climate variability and natural resource management can improve the decision process, especially for landscapes where decision points occur iteratively across time. In the Everglades, natural resource practitioners use models and decision support tools to assist their evaluations of restoration progress...

The Barrier Island Comprehensive Monitoring (BICM) program was developed by Louisiana’s Coastal Protection and Restoration Authority (CPRA) and is implemented as a component of the System Wide Assessment and Monitoring Program (SWAMP). The program uses both historical data and contemporary data collections to assess and monitor changes in the aerial and subaqueous extent of islands...

During December 2023, the U.S. Geological Survey collected ground-penetrating radar (GPR) data in select small peat bogs near the Quashnet River to map the depth to bedrock for use as inputs to a groundwater flow model. This data release contains the raw GPR data from 22 GPR profiles covering more than 1.8 kilometers.
