Data

These datasets, prepared by the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center, provide lidar-derived first-surface and bare-earth topography for a portion of the Texas coastline. Elevation measurements were acquired by the Experimental Advanced Airborne Research Lidar (EAARL) on September 27th and 28th, and October 2nd, 2005, following Hurricane Rita landfall.

Beaches are a dynamic interface between water and land and are frequently subjected to a range of natural hazards, which include flooding, storm effects, and coastal erosion. The U.S. Geological Survey (USGS) is conducting a national assessment of coastal change hazards across the Nation. One component of this research effort, the National Assessment of Shoreline Change Project, documents changes

The Atlantic Beach artificial reef, located on the sea floor 3 nautical miles south of Atlantic Beach, New York in about 20 meters water depth, was built to create habitat for marine life. The reef was originally created by placing heavy materials such as tires, automobile bodies and other vehicles, barges, and rock from a dredging project on the sea floor. In 2000, the U.S. Geological Survey surv

This data release includes geospatial datasets that were created to analyze wetland changes along the Virginia and Maryland Atlantic coasts between 1984 and 2015 as part of the U.S. Geological Survey's (USGS) Barrier Island and Estuarine Wetland Physical Change Assessment. Wetland change was determined by assessing two metrics: wetland persistence and land-cover switching. Because seasonal water l

Acoustic Doppler Current Profilers (ADCPs) and Pressure loggers were deployed at Crocker Reef, a senile (dead) barrier reef located in the northern portion of the Florida Reef Tract during December 12, 2014 to January 30, 2015. A pressure logger was deployed in the deepest part of the fore reef at a water depth of 14 m. This logger configured to measure pressure at a rate of 2 Hz to obtain wave st

Attenuation Factor (AF; Rao and others, 1985) and DRASTIC (Aller and others, 1987) models were developed for the Upper Floridan aquifer within the Southwest Florida Water Management District (SWFWMD) boundaries. The models were compared to assess the ability of each of these models to indicate the vulnerability of groundwater resources to contamination by Ethylene Dibromide and Bromacil pesticides

A multibeam survey was carried out in 2002 to map the bathymetry and backscatter intensity of the sea floor of the Hudson Canyon and adjacent slope and rise. The Canyon begins on the outer continental shelf off the eastern coast of the United States at about 100-meter (m) water depth and extends offshore southeastward across the continental slope and rise. The survey covered an area approximately

Water-level gauges were deployed at two sites in West Falmouth Harbor between May and October 2016. Two sequential deployments were required to provide measurements for the entire period. One gauge was mounted under the town-owned West Falmouth boat dock and the other on the private Associates dock near the mouth of the Harbor. Each gauge supported two pressure sensors mounted in a stilling we

This field activity is part of the effort to map geologic substrates of the Stellwagen Bank National Marine Sanctuary region off Boston, Massachusetts. The overall goal is to develop high-resolution (1:25,000) interpretive maps, based on multibeam sonar data and seabed sampling, showing surficial geology and seabed sediment dynamics. This cruise was conducted in collaboration with the Stellwagen B

Provided here are the SWAN wave model input of grid 4 with pit 3 configuration and output of significant wave height, dominant wave period, and mean wave direction resulting from simulation of wave scenarios at the Breton Island, LA, as described in USGS Open-File Report 2015-1055 (https://doi.org/10.3133/ofr20151055). There are 128 individual scenarios that are based on significant wave height (H

These datasets, prepared cooperatively by the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center and the National Park Service (NPS), provide lidar-derived first-surface and bare-earth topography for a portion of eastern Louisiana. Elevation measurements were acquired by the Experimental Advanced Airborne Research Lidar (EAARL) on March 9, 2008.

The U.S. Army Corps of Engineers contracted a beach survey of Fire Island, New York from September 17-October 6, 2013 for the purpose of planning of a beach reconstruction project following Hurricane Sandy. This dataset contains elevation data of subaerial morphology and nearshore bathymetry collected using real time kinematic global positioning system (RTK-GPS) and hydrography techniques. The dat
