1/9th Arc-second Digital Elevation Models (DEMs) - USGS National Map 3DEP Downloadable Data Collection

This is a tiled collection of the 3D Elevation Program (3DEP) and is 1/9 arc-second
(approximately 3 m) resolution.The 3DEP data holdings serve as the elevation layer of The
National Map, and provide foundational elevation information for earth science studies and
mapping applications in the United States. Scientists and resource managers use 3DEP data
for hydrologic modeling, resource monitoring, mapping and visualization, and many other
applications. The elevations in this DEM represent the topographic bare-earth surface. The
seamless 1/9 arc-second DEM layers are derived from diverse source data that are processed
to a common coordinate system and unit of vertical measure. These data are distributed in
geographic coordinates in units of decimal degrees, and in conformance with the North
American Datum of 1983 (NAD 83). All elevation values are in meters and, over the
continental United States, are referenced to the North American Vertical Datum of 1988
(NAVD88). The seamless 1/9 arc-second DEM layer project-based coverage for portions of the
conterminous United States, limited areas of Alaska, and Guam. The seamless 1/9 arc-second
NED layer is available as pre-staged products tiled in 15 minute blocks in Erdas .img
format. Since 2015, the seamless 1/9 arc-second DEM layer is no longer being updated. Other
3DEP products are nationally seamless DEMs in resolutions of 1/3, 1, and 2 arc seconds.
These seamless DEMs were referred to as the National Elevation Dataset (NED) from about 2000
through 2015 at which time they became the seamless DEM layers under the 3DEP program and
the NED name and system were retired. Other 3DEP products include one-meter DEMs produced
exclusively from high resolution light detection and ranging (lidar) source data and
five-meter DEMs in Alaska as well as various source datasets including the lidar point cloud
and interferometric synthetic aperture radar (Ifsar) digital surface models and intensity
images. All 3DEP products are public domain.

Donated AUV Chirp seismic-reflection data collected during Monterey Bay Aquarium Research Institute (MBARI) cruise in March 2019 offshore of south-central California

This dataset consists of autonomous underwater vehicle (AUV) Chirp seismic-reflection data collected in March 2019 aboard the R/V Rachel Carson, which is owned and operated by the Monterey Bay Aquarium Research Institute (MBARI). During the cruise, data were collected across eight AUV dives, all eight of which collected coincident bathymetry and Chirp seismic-reflection data. The collection of these data was funded entirely by MBARI, and the data have been donated to the U.S. Geological Survey (USGS). The data were collected in collaboration with the USGS and the Bureau of Ocean Energy Management (BOEM), and they are located in the same study area as the collaborative California Deepwater Investigations and Groundtruthing I (Cal DIG I) project. The purpose of the overall Cal DIG I study is to assess shallow geohazards, benthic habitats, and thereby the potential for alternative energy infrastructure (namely floating wind turbines) offshore south-central California due to the study area's proximity to power grid infrastructure associated with the Morro Bay power plant. The AUV data in this portion of the data release provide ultra-high-resolution subsurface imaging of eight different patches of seafloor offshore of the south-central California coast. The AUV mapping navigation has not been accurately positioned and is considered as only partially processed.

2-meter bathymetric data collected in 2012 by the U.S. Geological Survey in the Connecticut River during field activity 2012-024-FA (bathymetry and depth-colored hillshade relief GeoTIFFs)

A geophysical and geological survey was conducted at the mouth of the Connecticut River from Old Saybrook to Essex, Connecticut, in September 2012. Approximately 230 linear kilometers of digital Chirp subbottom (seismic-reflection) and 234-kilohertz interferometric sonar (bathymetric and backscatter) data were collected along with sediment samples, riverbed photographs, and (or) video at 88 sites within the geophysical survey area. Sediment grab samples were collected at 72 of the 88 sampling sites, video was acquired at 68 sites, and photographs of the river bottom were taken at 38 sites. These survey data are used to characterize the riverbed by identifying sediment-texture and riverbed morphology. More information can be found on the web page for the Woods Hole Coastal and Marine Science Center field activity: https://cmgds.marine.usgs.gov/fan_info.php?fan=2012-024-FA.

Location of sound velocity profiles along with profile plots collected by the U.S. Geological Survey in 2014 along the Delmarva Peninsula,  MD and VA (PNG images, CSV text, and Esri point shapefile, Geographic, WGS 84)

The Delmarva Peninsula is a 220-kilometer-long headland, spit, and barrier island complex that was significantly affected by Hurricane Sandy. A U.S. Geological Survey cruise was conducted in the summer of 2014 to map the inner continental shelf of the Delmarva Peninsula using geophysical and sampling techniques to define the geologic framework that governs coastal system evolution at storm-event and longer timescales. Data collected during the 2014 cruise include swath bathymetry, sidescan sonar, chirp and boomer seismic-reflection profiles, acoustic Doppler current profiler, and sample and bottom photograph data. Processed data in raster and vector format are released here for the swath bathymetry, sidescan sonar, and seismic-reflection profiles.  More information about the USGS survey conducted as part of the Hurricane Sandy Response-- Geologic Framework and Coastal Vulnerability Study can be found at the project website or on the WHCMSC Field Activity Web pages: https://woodshole.er.usgs.gov/project-pages/delmarva/ and https://cmgds.marine.usgs.gov/fan_info.php?fan=2014-002-FA

LANDFIRE 2016 Remap Existing Vegetation Height (EVH) Guam Northern Mariana Islands

LANDFIRE's (LF) 2016 Remap (Remap) Existing Vegetation Height (EVH) represents the average height of the dominant vegetation for a 30m cell. EVH is produced separately for tree, shrub, and herbaceous lifeforms using training data depicting the average height weighted by species cover and Existing Vegetation Type (EVT) lifeform. Decision tree models using field reference data, lidar, Landsat, and ancillary data are developed separately for each lifeform, then lifeform specific height class layers are merged along with land cover into a single EVH product. EVH ranges are continuous for herbaceous lifeform ranging from 0.1 to 1 meter with decimeter increments, 0.1 to 3 meters for shrub lifeform, and 1 to 99 meters for tree lifeform. If the height values of each lifeform exceed the continuous value range, they are binned into the appropriate maximum height class. EVH is then reconciled through QA/QC measures to ensure lifeform is synchronized with both Existing Vegetation Cover (EVC) and EVT products. Disturbance events not visible in the source imagery are accounted for by using LF Remap Annual Disturbance products. LF uses EVH as an input for LF Remap Fuel Vegetation Cover (FVH).

January 2010 bathymetry collected near Dumbarton Bridge in south San Francisco Bay, California

Bathymetric survey data were collected in January 2010 just south of Dumbarton Bridge in south San Francisco Bay, California. Portions of the main channel and western shallows/intertidal mudflats were surveyed using an interferometric sidescan sonar system following procedures detailed in Foxgrover and others, 2011. The bathymetry is provided as a 1-m resolution raster in geoTIFF format, referenced to the vertical datum of mean lower low water (MLLW). To convert to the North American Vertical Datum of 1988 (NAVD88), subtract a static offset of 0.37 m (datum conversions provided in Foxgrover and others, 2007).

Data to Accompany the Regional Potentiometric-Surface Map of the Great Basin Carbonate and Alluvial Aquifer System in Snake Valley and Surrounding Areas, Juab, Millard, and Beaver Counties, Utah and White Pine and Lincoln Counties, Nevada

Water-level measurements from 190 wells were used to develop a potentiometric-surface map of the 
east-central portion of the regional Great Basin carbonate and alluvial aquifer system in and around 
Snake Valley, eastern Nevada and western Utah. The map area covers approximately 9,000 square 
miles in Juab, Millard, and Beaver Counties, Utah, and White Pine and Lincoln Counties, Nevada. 
Recent (2007-2010) drilling by the Utah Geological Survey and U.S. Geological Survey has provided 
new data for areas where water-level measurements were previously unavailable. New water-level data 
were used to refine mapping of the pathways of intrabasin and interbasin groundwater flow. At 20 of 
these locations, nested observation wells provide vertical hydraulic gradient data and information 
related to the degree of connection between basin-fill aquifers and consolidated-rock aquifers. 
Multiple-year water-level hydrographs are also presented for 32 wells to illustrate the aquifer 
system’s response to interannual climate variations and well withdrawals.

USGS Arctic Ocean Carbon Cruise 2012: Discrete Underway Laboratory data

Models project the Arctic Ocean will become undersaturated with respect to carbonate minerals in the next decade.  Recent field results indicate parts may already be undersaturated in late summer months when ice melt is at its greatest extent; however, few comprehensive datasets of carbonate system parameters in the Arctic Ocean exist.  Researchers from the U.S. Geological Survey (USGS) and University of South Florida (USF) collected high-resolution measurements of pCO2, pH, total dissolved inorganic carbon (DIC), total alkalinity (TA), and carbonate (CO3-2) from the Canada Basin to fill critical information gaps concerning Arctic carbon variability.  A Multiparameter Inorganic Carbon Analyzer (MICA) was used to collect approximately 1,800 measurements of pH and DIC along an 11,965-km trackline in August and September 2012. In addition, over 500 discrete surface water samples were taken. These data are being used to characterize and model regional pCO2, pH, and carbonate mineral saturation state. A high-resolution, three-dimensional map of these results will be presented.

STCR2014_EAARLB_v09g12B_metadata: EAARL-B Submerged Topography–Saint Croix, U.S. Virgin Islands, 2014

ASCII XYZ point cloud data for a portion of the submerged environs of Saint Croix, U.S. Virgin Islands, was produced from remotely sensed, geographically referenced elevation measurements collected on March 11, 19, and 21, 2014 by the U.S. Geological Survey, in collaboration with the National Oceanic and Atmospheric Administration (NOAA) Coral Reef Conservation Program. 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 spacing of 0.5?1.6 meters. The nominal vertical elevation accuracy expressed as the root mean square error (RMSE) is 13.5 centimeters. 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.
