Geospatial characterization of Atlantic-facing New Jersey salt marshes Geospatial characterization of Atlantic-facing New Jersey salt marshes
This data release contains coastal wetland synthesis products for the Atlantic-facing New Jersey salt marshes. Metrics for resiliency, including the unvegetated to vegetated ratio (UVVR), marsh elevation, and tidal range, are calculated for smaller units delineated from a digital elevation model, providing the spatial variability of physical factors that influence wetland health. The U.S
Geospatial characterization of salt marshes in Maine Geospatial characterization of salt marshes in Maine
This data release contains coastal wetland synthesis products for the state of Maine. Metrics for resiliency, including the unvegetated to vegetated ratio (UVVR), marsh elevation, tidal range, and lifespan, are calculated for smaller units delineated from a digital elevation model, providing the spatial variability of physical factors that influence wetland health. The U.S. Geological...

There are 70 full or partial 8-digit hydrologic units (HU8) represented in the Nevada StreamStats study area: 15010005 (partial), 15010006 (partial), 15010008, 15010009, 15010010...
Geospatial data sets and hydraulic models for the Cuyahoga River near Jaite, Ohio Geospatial data sets and hydraulic models for the Cuyahoga River near Jaite, Ohio
Digital flood-inundation maps for a nearly 6-mile reach of the Cuyahoga River at Jaite, Ohio, were created by the U.S. Geological Survey (USGS) in cooperation with the Northeast Ohio Regional Sewer District Board of Commissioners. The flood-inundation maps, which can be accessed through the USGS Flood Inundation Mapping (FIM) Program website at https://www.usgs.gov/mission-areas/water...
Geospatial database for the geomorphic map of the Umatilla River corridor, Oregon Geospatial database for the geomorphic map of the Umatilla River corridor, Oregon
This map portrays the distribution of landforms along the Umatilla River in northeastern Oregon and covers a corridor 127 kilometers (km) long from the confluence of the Umatilla River with the Columbia River upstream to Meacham Creek. The map encompasses the valley bottom and extends about 1 km up the adjoining hillslopes. Map data are intended to support water quality and fisheries...
Geospatial database of the 2022 summit and Northeast Rift Zone eruption of Mauna Loa volcano, Hawai'i Geospatial database of the 2022 summit and Northeast Rift Zone eruption of Mauna Loa volcano, Hawai'i
In the late evening of November 27, 2022, an effusive eruption began inside Moku'aweoweo caldera at the summit of Mauna Loa volcano. Within a few hours, lava had covered most of the caldera floor, and several fissures just outside caldera sent short lava flows up to 3 kilometers (2 miles) to the southwest. Later in the morning of November 28, summit effusion ceased and the eruption moved...
Geospatial Dataset for the Geologic Framework and Hydrostratigraphy of the Edwards and Trinity Aquifers Within Northern Medina County, Texas at 1:24,000 Geospatial Dataset for the Geologic Framework and Hydrostratigraphy of the Edwards and Trinity Aquifers Within Northern Medina County, Texas at 1:24,000
The karstic Edwards and Trinity aquifers are classified as major sources of water in south-central Texas by the Texas Water Development Board, and both are classified as major aquifers by the State of Texas. The Edwards and Trinity aquifers developed because of the original depositional history of the carbonate limestone and dolomite rocks that contain them, and the primary and secondary...
Geospatial Dataset for the Geologic Framework and Hydrostratigraphy of the Edwards and Trinity Aquifers Within Parts of Bandera and Kendall Counties, Texas, at 1:24,000 Geospatial Dataset for the Geologic Framework and Hydrostratigraphy of the Edwards and Trinity Aquifers Within Parts of Bandera and Kendall Counties, Texas, at 1:24,000
The karstic Edwards and Trinity aquifers are classified as major sources of water in south-central Texas by the Texas Water Development Board, and both are classified as major aquifers by the State of Texas. The purpose of this data release is to present the data that were collected and compiled to describe the geologic framework and hydrostratigraphy within parts of Bandera and Kendall...
Geospatial dataset of depressions, sinking streams, and associated watersheds in karst areas of Tennessee and parts of surrounding states Geospatial dataset of depressions, sinking streams, and associated watersheds in karst areas of Tennessee and parts of surrounding states
“Karst” landscapes are characterized by distinctive hydrology and surface features, such as closed depressions, sinkholes, and sinking streams, that result from high rock solubility and well-developed fracture porosity (Ford and Williams, 2007; Weary and Doctor, 2014). Soluble carbonate rocks underlie most of Middle Tennessee, large areas of East Tennessee, and parts of surrounding...
Geospatial datasets and hydraulic model for flood-inundation maps for the Cuyahoga River in and near the City of Independence, Ohio Geospatial datasets and hydraulic model for flood-inundation maps for the Cuyahoga River in and near the City of Independence, Ohio
Digital flood-inundation maps for a 9.9-mile reach of the Cuyahoga River near Independence, Ohio, were created by the U.S. Geological Survey (USGS) in cooperation with the Northeast Ohio Regional Sewer District Board of Trustees. Flood profiles were computed for the stream reach by means of a one-dimensional step-backwater model. The model was calibrated to the current (rating number 42)...
Geospatial datasets for Glacial geology and hydrogeology of valley-fill aquifers in the Oneonta area, Otsego and Delaware Counties, New York Geospatial datasets for Glacial geology and hydrogeology of valley-fill aquifers in the Oneonta area, Otsego and Delaware Counties, New York
From 2016 to 2018, the U.S. Geological Survey, in cooperation with The New York State Department of Environmental Conservation, conducted a study of the glacial geology and hydrogeology of valley-fill (sand and gravel) aquifers and surrounding uplands within a 112-square-mile area in southern Otsego and northwestern Delaware Counties, New York, centered around the city of Oneonta. The...
Geospatial datasets of seabed topography, sediment mobility, and the distribution of geologic substrates in quadrangle 2 of the Stellwagen Bank National Marine Sanctuary region offshore of Boston, Massachusetts Geospatial datasets of seabed topography, sediment mobility, and the distribution of geologic substrates in quadrangle 2 of the Stellwagen Bank National Marine Sanctuary region offshore of Boston, Massachusetts
The U.S. Geological Survey (USGS), in cooperation with the National Marine Sanctuary Program of the National Oceanic and Atmospheric Administration (NOAA), has conducted seabed mapping and related research in the Stellwagen Bank National Marine Sanctuary (SBNMS) region since 1993. The interpretive datasets and source information presented here are for quadrangle 2, which is one of 18...
