(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.

Based on hydrologic data through the 2022 water year (October 1 to September 30), the U.S. Geological Survey South Atlantic Water Science Center updated low-flow frequency, mean annual flow, and flow-duration statistics at 843 streamgages in and near Georgia, North Carolina, and South Carolina. Data from 604 of those streamgages, on streams not substantially affected by regulation or...

This data release (DR) is the update of the U.S. Geological Survey - ScienceBase (SB) DR (Bera, 2025b), with the processed data for the period October 1, 2023, through September 30, 2024. This DR describes the watershed data management (WDM) database file SC24.WDM. The precipitation data are collected from a tipping-bucket rain gage network and the hydrologic data (stage and discharge)...

These data were compiled for the National Park Service. Objective(s) of our study were to resurvey previously established cross sections on the Green River in Browns Park, Colorado and Utah, to document changes in channel width, depth, and cross-sectional area. In addition, new cross sections were established in areas that lacked previously surveyed cross sections. These data represent...

Because urban landscapes are heterogeneous, the methods and spatial resolution used to depict the land surface greatly influence the representation of urban features. Land cover products such as tree canopy cover (TCC) are particularly sensitive to the methodology and resolution used in their creation. Differences in TCC mapping have implications on the outcomes of ecosystem service (ES)...

A benchmark global water balance evapotranspiration (WBET) dataset was generated using machine learning for large-area bias correction of remote sensing-based evapotranspiration (RSET). The dataset contains WBET (1991-2020 average) of over 15,000 Level 6 HydroBASINS worldwide. Additionally, a comparison of this dataset with three RSET and a machine learning-based global datasets is...
