ASIS2003_EAARLA_BE_z18_n88g99_metadata: EAARL Coastal Topography--Northern Assateague Island National Seashore, Maryland and Virginia, 2003: Bare Earth

ASCII XYZ point cloud data were produced from remotely sensed, geographically referenced elevation measurements acquired cooperatively by the U.S. Geological Survey (USGS) and the National Park Service (NPS). Elevation measurements were collected over northern Assateague Island National Seashore using the first-generation National Aeronautics and Space Administration (NASA) Experimental Advanced Airborne Research Lidar (EAARL), a pulsed laser ranging system mounted onboard an aircraft to measure ground elevation, vegetation canopy, and coastal topography. The system uses high-frequency laser beams directed at the Earth's surface through an opening in the bottom of the aircraft's fuselage. The laser system records the time difference between emission of the laser beam and the reception of the reflected laser signal in the aircraft. The plane travels over the target area at approximately 60 meters per second at an elevation of approximately 300 meters, resulting in a laser swath of approximately 240 meters with an average point spacing of 2-3 meters. The EAARL, developed originally by NASA at Wallops Flight Facility in Virginia, measures ground elevation with a vertical resolution of 3 centimeters. A sampling rate of 3 kilohertz or higher results in an extremely dense spatial elevation dataset. Over 100 kilometers of coastline can be surveyed easily within a 3- to 4-hour mission. When resultant elevation maps for an area are analyzed, they provide a useful tool to make management decisions regarding land development.

Multibeam backscatter data collected during USGS Field Activity 2021-004-FA, using a dual-head Teledyne SeaBat T20-P multibeam echo sounder (8-bit GeoTIFF, UTM Zone 19N, WGS84, 1-m resolution)

The U.S. Geological Survey (USGS) Woods Hole Coastal and Marine Science Center (WHCMSC) completed a bathymetric and shallow seismic-reflection survey during the period of June 9, 2021 to June 24, 2021 in water depths from 2 m to 30 m for a portion of the outer Cape Cod nearshore environment between Marconi and Nauset Beaches. The products from this survey will help to support white shark research on their shallow-water behavior in the dynamic nearshore environment at Cape Cod National Seashore (CACO). CACO visitors’ safety is threatened by interactions between the public and white sharks. This project provides CACO with baseline data and information on nearshore white shark habitat, specifically in the nearshore shoreface, bathymetric trough, and longshore bar. This data release provides the geophysical  data collected from outer Cape Cod during USGS Field Activities 2021-002-FA in 2021.

Interpreted and Uninterpreted Seismic-Reflection Profiles from the inner continental shelf off the northern Oregon and southern Washington coast (HTML files)

Two 21-day field operations were conducted in 1997 and
1998 in the estuaries and on the inner continental shelf off
the northern Oregon and southern Washington coast.
These cruises aboard the R/V Corliss were run in order to
generate reconnaissance maps of the seafloor geology
and the shallow subsurface stratigraphy using sidescan
sonar and seismic-reflection mapping techniques. The
1998 cruise also collected sediment grab samples, bottom
photographs, and video images to verify the
sidescan-sonar imagery and to document the seafloor
geology. The combination of these data with previously
collected sediment sample data (Robert, 1974; Nittrouer,
1978; and Smith et. al., 1980) has been used to define the
extent and lithology of shelf sediments associated with the
Columbia River littoral cell. This work is one component of
a larger project studying the erosion of the Washington and
Oregon coast and is being coordinated by the U.S.
Geological Survey and the Washington State Department
of Ecology. The reason for collecting these data is to
provide a regional synthesis of the offshore geology to
support a wide variety of management decisions and to
provide a basis for further process-oriented investigations.

Airborne geophysical survey: Taylor Mountains

Aeromagnetic data were collected along flight lines by instruments in an aircraft that recorded magnetic-field intensity values and location. In surveys such as this one where the data were originally collected in digital form and not digitized from contour maps, the information we provide typically includes latitude, longitude, magnetic anomaly in nanoTeslas, and intermediate values used to derive the magnetic anomaly such as total magnetic field.

Underwater temperature data collected from off-shore coral reefs of the Florida Keys, U.S.A. (Version 6)

The U.S. Geological Survey (USGS) Coral Reef Ecosystems Studies (CREST) project (https://coastal.er.usgs.gov/crest/) provides science that helps resource managers tasked with the stewardship of coral reef resources. Coral reef organisms are very sensitive to high and low water-temperature extremes. It is critical to precisely know water temperatures experienced by corals and associated plants and animals that live in the dynamic nearshore environment to document thresholds in temperature tolerance. This dataset provides underwater temperature data recorded every fifteen minutes from 2009 to 2020 at six off-shore coral reefs in the Florida Keys, USA. From northeast to southwest, these sites are Fowey Rocks (Biscayne National Park), Molasses Reef (Florida Keys National Marine Sanctuary, FKNMS, site terminated in 2013), Crocker Reef (FKNMS, site added in 2013), Sombrero Reef (FKNMS), Pulaski Shoal Light (Dry Tortugas National Park), and Pulaski Shoal West (Dry Tortugas National Park, site added in 2016). A portion of the dataset included here was interpreted in conjunction with coral and algal calcification rates in Kuffner and others (2013).

Station and data summary for data collected on Stellwagen Bank during U.S. Geological Survey field activity 2014-066-FA, aboard the R/V Auk, November 10, 2014

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 Bank National Marine Sanctuary, and the data collected will aid research on the ecology of fish and invertebrate species that inhabit the region. The Sanctuary's research vessel, R/V Auk, visited 44 locations on Stellwagen Bank at which a customized Van Veen grab sampler (SEABOSS) equipped with a video camera and a CTD was deployed in drift mode to collect sediment for grain-size analysis, video imagery of the seabed, and measurements of water column properties.

Benthic habitats of the coral reef ecosystem off the coast of Pu'ukohola Heiau (PUHE) National Historic Site

A benthic habitat polygon coverage has been created of the coral reef ecosystem off the coast of Pu'ukohola Heiau (PUHE) National Historic Site on the Kona Coast of Hawai'i. Polygons were hand-digitized from visual interpretation of aerial photography and SHOALS bathymetry data. We also utilized in situ knowledge from towed instruments, underwater photography and videography, and diver and snorkeler observations. The polygons have attributes for Main Structure/Substrate, Dominant Structure/Substrate, Major Biological Cover, Percent of Major Biological Cover, Reef Zone, and  Unique ID, and measurements of area (m2) of each polygon.

Wilderness Breach Bathymetry Data Collected in June 2014 from Fire Island, New York: 25-Meter Digital Elevation Model

Scientists from the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center in St. Petersburg, Florida, collected bathymetric data along the upper shoreface and within the wilderness breach at Fire Island, New York, in June 2014. The U.S. Geological Survey is involved in a post-Hurricane Sandy effort to map and monitor the morphologic evolution of the shoreface along Fire Island and model the evolution of the wilderness breach as a part of the Hurricane Sandy Supplemental Project GS2-2B.During this study, bathymetry was collected with single-beam echo sounders and global positioning systems, mounted to personal watercraft, along the Fire Island shoreface and within the wilderness breach. Additional bathymetry was collected using backpack global positioning systems along the flood shoals and shallow channels within the wilderness breach.

Initial hydraulic heads for the transient ground-water flow model, Death Valley regional ground-water flow system, Nevada and California

This digital data set defines the hydraulic-head values in 16 model layers used to initiate the transient 
simulation of the Death Valley regional ground-water flow system (DVRFS) model. The area simulated 
by the DVRFS transient ground-water flow model is an approximately 45,000 square-kilometer region 
of southern Nevada and California. In order to reduce model execution time, hydraulic head values 
output from the steady-state simulation of the DVRFS were used as starting hydraulic heads for the 
transient simulation of the DVRFS ground-water flow model. The DVRFS transient ground-water flow 
model is one of the most recent in a number of regional-scale models developed by the U.S. Geological 
Survey (USGS) for the U.S. Department of Energy (DOE) to support investigations at the Nevada Test 
Site (NTS) and at Yucca Mountain, Nevada (see "Larger Work Citation", Chapter A, page 8).

PDF format log books of data collection in Lake Mead in 2000

Lake Mead is a large interstate reservoir located in the Mojave Desert of southeastern Nevada and northwestern Arizona.  It was impounded in 1935 by the construction of Hoover Dam and is one of a series of multi-purpose reservoirs on the Colorado River.  The lake extends 183 km from the mouth of the Grand Canyon to Black Canyon, the site of Hoover Dam, and provides water for residential, commercial, industrial, recreational, and other non-agricultural users in communities across the southwestern United States.  Extensive research has been conducted on Lake Mead, but a majority of the studies have involved determining levels of anthropogenic contaminants such as synthetic organic compounds, heavy metals and dissolved ions, furans/dioxins, and nutrient loading in lake water, sediment, and biota (Preissler, et al., 1998; Bevans et al, 1996; Bevans et al., 1998; Covay and Leiker, 1998; LaBounty and Horn, 1997; Paulson, 1981).  By contrast, little work has focused on the sediments in the lake and the processes of deposition (Gould, 1951).  To address these questions, sidescan-sonar imagery and high-resolution seismic-reflection profiles were collected throughout Lake Mead by the USGS in cooperation with researchers from University of Nevada Las Vegas (UNLV).  These data allow a detailed mapping of the surficial geology and the distribution and thickness of sediment that has accumulated in the lake since the completion of Hoover Dam.  Results indicate that the accumulation of post-impoundment sediment is primarily restricted to former river and stream beds that are now submerged below the lake while the margins of the lake appear to be devoid of post-impoundment sediment.  The sediment cover along the original Colorado River bed is continuous and is typically greater than 10 m thick through much of its length.  Sediment thickness in some areas exceeds 35 m while the smaller tributary valleys typically are filled with less than 4 m of sediment.  Away from the river beds that are now covered with post-impoundment sediment, pre-impoundment alluvial deposits and rock outcrops are still exposed on the lake floor.
