Water_Level_all: Modeling the effects of large-scale interior headland restoration on tidal hydrodynamics and salinity transport in an open coast, marine-dominant estuary: model input and results

Using version 20.1_19 of the Discontinuous-Galerkin Shallow Water Equations Model (DG-SWEM) (Kubatko and others, 2006), astronomic tides and salinity transport were simulated at Grand Bay, Alabama (AL), under scenarios of interior headland restoration and sea level rise, as described in Passeri and others (2023). The two-dimensional DG-SWEM model can be applied to coastal and estuarine systems to solve for time-dependent hydrodynamic circulation and salinity transport. The DG-SWEM model uses the ADCIRC framework (Luettich and others, 1992) and requires inputs of an unstructured finite element mesh. For this study, the mesh domain has an open ocean boundary in the Gulf of Mexico and has higher spatial resolution elements (20 - 100 meters [m]) along the Mississippi and Alabama coast. The model mesh coordinates (latitude and longitude) and simulated maximum water surface elevations are included in this data release. For further information regarding model input generation and visualization of model output, refer to Passeri and others (2023).

LANDFIRE 2016 Remap Existing Vegetation Cover (EVC) Puerto Rico US Virgin Islands

LANDFIRE's (LF) 2016 Remap (Remap) Existing Vegetation Cover (EVC) represents the vertically projected percent cover of the live canopy for a 30m cell. EVC is produced separately for tree, shrub, and herbaceous lifeforms. Training data depicting percentages of canopy cover are obtained from plot-level ground-based visual assessments and lidar observations. These are combined with Landsat imagery (from multiple seasons), topographic, climate, and other geospatial data sets to inform models built independently for each lifeform. Tree, shrub, and herbaceous lifeforms each have a potential range from 10% to 100%. The three independent lifeform datasets are merged into a single product. The EVC product is then reconciled through QA/QC measures to ensure lifeform is synchronized with both Existing Vegetation Height (EVH) and Type (EVT) products. Disturbance events not visible in the source imagery are accounted for by incorporating LF Remap Annual Disturbance products. LF uses EVC as an input for LF Remap Fuel Vegetation Cover (FVC).

Boundary of the ground-water flow model by IT Corporation (1996), for the Death Valley regional ground-water flow system study, Nevada and California

This digital data set defines the boundary of the steady-state ground-water flow model built by 
IT Corporation (1996). The regional, 20-layer ground-water flow model was developed for the 
Underground Test Area (UGTA) Phase I project to simulate the Nevada Test Site and surrounding 
areas. The model was used for estimating the amount of water moving through the ground-water 
system, predicting the movement of contaminants, evaluating uncertainty in these predictions, 
and supplying boundary conditions for more detailed models of the underground testing areas. 
The U.S. Geological Survey integrated the IT Corporation (1996) model with the ground-water 
flow model by D'Agnese and others (1997) to develop a transient flow model of  the Death 
Valley regional ground-water flow system (DVRFS) for the Department of Energy in 2004 
(see "Larger Work Citation", Chapter A, pages 7-9, for details).

Airborne geophysical survey: East Alaska Range

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.

Groundwater Discharge Area for the Diamond Valley Flow System, Central Nevada

These data were created as part of a hydrologic study to characterize groundwater budgets and water quality 
in the Diamond Valley Flow System (DVFS), central Nevada. This dataset represents the groundwater 
discharge area (GDA) in the DVFS. Vegetated areas within the GDA are composed of phreatophytic 
shrubs with smaller areas of grassland, marshland, xeric vegetation, bare soil, and agricultural lands 
where phreatophytic shrubs historically were present. Vegetated areas outside the GDA are primarily 
composed of xeric vegetation and bare soil although very sparse phreatophytic shrubs may be present 
on the outer margins of the boundary. The GDA was mapped in the summer of 2011 using field 
reconnaissance and supporting digital data. Additional supporting field information was gathered in fall 
of 2014.

Assateague Island surface and subsurface sediment physical parameters data from the spring and fall sampling trips of 2014

The influence of tropical and extratropical cyclones on coastal wetlands and marshes is highly variable in both space and time and depends on a number of climatic, geologic, and physical variables.  The impacts storms can be either positive or negative with respect to the wetland and marsh ecosystems. Small to moderate amounts of inorganic sediment added during storms or other events helps to abate pressure from sea-level rise.  However, if the volume of sediment is large and the resulting deposits thick, the organic substrate may compact causing submergence and a loss in elevation.  Similarly, thick deposits of coarse inorganic sediment may also alter the hydrology of the site and impede vegetative processes.  Alternative impacts associated with storms include shoreline erosion at the marsh edge as well as potential emergence.  Predicting the outcome of these various responses and potential long-term implications can be obtained from a systematic assessment of both historical and recent event deposits.  The objectives of this study are to 1) characterize the surficial sediment of the relict to recent washover fans and back-barrier marshes, and 2) characterize the sediment of 6 marsh cores from the back-barrier marshes and a single marsh island core near the mainland.  These geologic data will be integrated with other remote sensing data collected along Assateague Island, Maryland / Virginia and assimilated into an assessment of coastal wetland response to storms.

CRKR2014_EAARLB_z17_n88g12A_metadata: EAARL-B Submerged Topography—Crocker Reef, Florida, 2014

ASCII XYZ point cloud data for a portion of the submerged environs of Crocker Reef, Florida, were produced from remotely sensed, geographically referenced elevation measurements collected on April 13 and 22, 2014 by the U.S. Geological Survey. Elevation measurements were collected over the area using the second-generation Experimental Advanced Airborne Research Lidar (EAARL-B), 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 55 meters per second at an elevation of approximately 300 meters, resulting in a laser swath of approximately 240 meters with an average point density of 0.9 points per square meter. A peak sampling rate of 15-30 kilohertz results in an extremely dense spatial elevation dataset. More than 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 bathymetry data collected in four surveys offshore of south-central California in support of the Bureau of Ocean Energy Management Cal DIG I offshore alternative energy project

Multibeam acoustic-bathymetry data were collected offshore of Morro Bay, California, from 2016 to 2019. The data were collected during five separate multi-agency surveys for the U.S. Geological Survey (USGS)/Bureau of Ocean Energy Management (BOEM) California Deepwater Investigations and Groundtruthing I (Cal DIG I) project, under a collaboration with the National Oceanic and Atmospheric Administration (NOAA), using Simrad 700 series hull-mounted multibeam echosounders. Data in 2017 and 2018 were acquired by the NOAA Hydrographic Vessel Rainier (surveys H1309, H13151, and H13152). The 2018 data acquired by the Ranier were collected during USGS field activity 2018-641-FA. Additional data were collected in 2019 by the NOAA Hydrographic Survey Vessel Fairweather (survey W00479). Data from the Scripps Institution of Oceanography R/V Sally Ride collected in 2016 (survey SR1604) were used to fill in a small gap in the NOAA data. The acoustic-backscatter data from the five surveys were combined into a single raster and are provided as a 10-meter resolution GeoTIFF.

COW_Q35.TIF - U.S. Pacific West Coast EEZ GLORIA sidescan-sonar data mosaic (35 of 36) (TM, 50 m, NAD27)

In March 1983, President Ronald Reagan signed a proclamation establishing an Exclusive Economic Zone (EEZ) of the United States extending its territory 200 nautical miles from the coasts of the United States, Puerto Rico, the Northern Mariana Islands, and the U.S. territories and possessions. In 1984, the U.S. Geological Survey (USGS), Office of Marine Geology began a program to map these areas of the EEZ. The U.S. Pacific Coast was the first EEZ region to be mapped and launched GLORIA (Geological LOng-Range Inclined Asdic) mapping program. The area covered by this survey extended from the Mexican to the Canadian borders and from the continental shelf edge, at about the 400-meter bathymetric contour, to 200 nautical miles from the coast. Survey of the U.S. Pacific West Coast EEZ was completed in four consecutive cruises conducted from late April through mid-August 1984. The collected GLORIA data were processed and digitally mosaicked to produce continuous imagery of the seafloor. A total of 36 digital mosaics of an approximate 2 degree by 2 degree (or smaller) area with a 50-meter pixel resolution were completed for the region.

Deep-Towed Chirp Profiles of the Blake Ridge Collapse Structure Collected on USGS cruises 92023 and 95023 Aboard the R/V Cape Hatteras in 1992 and 1995

This CD-ROM contains copies of the navigation and deep-towed chirp subbottom data collected aboard the R/V Cape Hatteras,on cruises 92023 and 95023 in 1992 and 1995 respectively. This CD-ROM is (Compact Disc-Read Only Memory UDF (Universal Disc Format) CD-ROM Standard (ISO 9660 equivalent). The HTML documentation is written utilizing some HTML 4.0 enhancements. The disk should be viewable by all WWW browsers but may not properly format on some older WWW browsers. Also, some links to USGS collaborators and other agencies are available on this CD-ROM. These links are only accessible if access to the Internet is available during browsing of the CD-ROM. On cruise 92023, 58 km of deep-towed chirp data were recorded on 4 lines and broken into a total of 8 files. 78 square kilometers of sidescan mosaic and approximately 1000 km of air gun single channel seismic reflection data were recorded as well but are not achived on this report. On cruise 95023, 100km of deep- towed chirp data were recorded on 5 lines and broken into 18 files. 152 square kilometers of sidescan mosaic and 244.3 km of GI gun single channel seismic reflection were also recorded but are not archived on this report. The archived Chirp subbottom data are in standard Society of Exploration Geologists (SEG) SEG-Y format (Barry and others, 1975) and may be downloaded for processing with software such as Seismic Unix or SIOSEIS. The subbottom data were recorded on the ISIS data acquisition system in QMIPS format. Chirp subbottom channel extracted from raw QMIPS format sonar files and converted to 16-bit Int. SEG-Y format using the program QMIPSTOSEGY. Even though the data are in SEG-Y format, it is not the conventional time series data (e.g. voltages or pressures), but rather instantaneous amplitude or envelope detected and therefore all of the amplitudes are positive (though not simply rectified).
