Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Early to Mid-Pliocene Sedimentological Data from the Yorktown Formation, near Jamestown, Virginia Early to Mid-Pliocene Sedimentological Data from the Yorktown Formation, near Jamestown, Virginia
Data consists of grain size distribution by weight in grams of samples collected from the Yorktown Formation from various localities along the James River near Smithfield and Williamsburg, Virginia. In total, data from 34 samples are included in this dataset.
Supporting Datasets and R Code for Compound Flood Hazard Modeling in the New York - Long Island Sound Region Supporting Datasets and R Code for Compound Flood Hazard Modeling in the New York - Long Island Sound Region
This data release includes a shapefile of compound flood hazard scores and the associated input data, scripts, and a sample output file necessary for calculating rain-surge return period adjustments for Long Island Sound and its surrounding areas. The raw input data and imputation scripts are included in this data release and are located in the "Imputation and data compilation.zip"...
Soil depth layer for the Greater Everglades Soil depth layer for the Greater Everglades
The Everglades Vulnerability Analysis (EVA) is a series of connected, modular Bayesian networks that predict the response of several Everglades indicators of ecosystem health to changes in hydrology, salinity, and the landscape. We created a soil depth layer for use in the sawgrass peat module by using universal kriging to estimate soil depth at a 400-meter resolution for individual...
Cosmogenic Nuclide, Thermally Transferred Optically Stimulated Luminescence, and Paleomagnetic data from cave sediments from Fitton Cave, northern Arkansas Cosmogenic Nuclide, Thermally Transferred Optically Stimulated Luminescence, and Paleomagnetic data from cave sediments from Fitton Cave, northern Arkansas
This data release contains tabular data (comma-separated-value format) obtained for analyses of cosmogenic nuclides, thermally transferred optically stimulated luminescence, and paleomagnetism that were collected to constrain the age of sediments within Fitton Cave, Buffalo National River, north-central Arkansas.
Catch and mark-recapture data to estimate abundance of humpback chub Gila cypha in western Grand Canyon from 2010-2024 Catch and mark-recapture data to estimate abundance of humpback chub Gila cypha in western Grand Canyon from 2010-2024
This dataset describes the catch of humpback chub (Gila cypha) in baited hoop nets from humpback chub aggregations monitoring trips that occurred 2010-2024. Additionally, this data set includes tables that describe the number of captures and recaptures for repeat visits (i.e., mark-recapture) as well as categorical habitat scores from two experts assigned to the Colorado River in western...
Geospatial Dataset of Coastal Inundation Maps for Long Island, NY and Long Island Sound (CT/NY) Geospatial Dataset of Coastal Inundation Maps for Long Island, NY and Long Island Sound (CT/NY)
This data release contains shapefiles and raster data of spatially distributed water level inundation, water depth, wave discharge and a set of hazard ranks for water levels, waves, and a combination of both for coastal areas of Long Island, NY and Long Island Sound. Water inundation and depth data include both current and future projections of inundation based on 4 annual exceedance...
