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...
MODFLOW 6 Models Used to Simulate Groundwater Flow and Nitrogen Transport in the Long Island Sound Watershed on Long Island, New York (ver. 2.0, January 2026) MODFLOW 6 Models Used to Simulate Groundwater Flow and Nitrogen Transport in the Long Island Sound Watershed on Long Island, New York (ver. 2.0, January 2026)
This groundwater model archive documents coupled transient and steady-state regional and inset numerical models of the Long Island aquifer system to simulate groundwater flow and nitrogen transport using the US Geological Survey groundwater modeling software MODFLOW 6 (Langvin and others, 2017 and 2022). The regional model domain encompasses all of Long Island, New York, while the inset...
Topographic and bathymetric data, aerial imagery, and GPS data collected during UxS operations at Marconi Beach, Cape Cod National Seashore, Massachusetts between September 2024 and March 2025 - Imagery dataset Topographic and bathymetric data, aerial imagery, and GPS data collected during UxS operations at Marconi Beach, Cape Cod National Seashore, Massachusetts between September 2024 and March 2025 - Imagery dataset
Small Uncrewed Aircraft Systems (sUAS) were used to collect aerial remote sensing data over Marconi Beach on Cape Cod National Seashore, Wellfleet, Massachusetts. The USGS has a stationary camera system (CoastCam) and Meterological station overlooking the beach north of the parking lot on the bluff to observe waves and total water levels. The area experienced multiple large erosion...
Topographic and bathymetric data, aerial imagery, and GPS data collected during UxS operations at Marconi Beach, Cape Cod National Seashore, Massachusetts between September 2024 and March 2025 Topographic and bathymetric data, aerial imagery, and GPS data collected during UxS operations at Marconi Beach, Cape Cod National Seashore, Massachusetts between September 2024 and March 2025
Surveys with Uncrewed Systems (UxS) were used to collect remote sensing data at Marconi Beach on Cape Cod National Seashore, Wellfleet, Massachusetts after the area experienced multiple erosion events after fall storms in 2024 and the loss of National Park Service beach access stairs. The USGS has a stationary camera system (CoastCam) and meteorological station north of the parking lot...
Channel bed hydraulic conductivity, stage, and evapotranspiration data at Bosque del Apache National Wildlife Refuge, New Mexico, 2022-2024 Channel bed hydraulic conductivity, stage, and evapotranspiration data at Bosque del Apache National Wildlife Refuge, New Mexico, 2022-2024
Bosque del Apache National Wildlife Refuge (the Refuge), located in central New Mexico was established in 1939 with the mission to provide habitats for federally listed species and other migrating waterfowl. The U.S. Geological Survey and the U.S. Fish and Wildlife Service jointly developed a study to evaluate uncertainty in the major water budget components. Before this study, it was...
