Sun-illuminated topographic imagery of the seafloor in the Stellwagen Bank National Marine Sanctuary region (sunillum.tif)

The sun-illuminated topographic imagery of the Stellwagen Bank National Marine Sanctuary region off Boston, Massachusetts covers an area of approximately 1100 square nautical miles. The Stellwagen Bank NMS Mapping Project is designed to provide detailed maps of the Stellwagen Bank region's environments and habitats and the first complete multibeam topographic and sea floor characterization maps of a significant region of the shallow EEZ.  Data were collected on four cruises over a two year period from the fall of 1994 to the fall of 1996. The surveys were conducted aboard the Canadian Hydrographic Service vessel Frederick G. Creed, a SWATH (Small Waterplane Twin Hull) ship that surveys at speeds of up to 16 knots.

Unique common mid-point (cmp) navigation for multi-channel seismic data collected by the U.S. Geological Survey on U.S. Atlantic Seaboard in 2014 (Geographic, WGS84,  point shapefile 2014-011-FA_mcscmp.shp)

In summer 2014, the U.S. Geological Survey conducted a 21-day geophysical program in deep water along the Atlantic continental margin by using R/V Marcus G. Langseth (Field Activity Number 2014-011-FA). The purpose of the seismic program was to collect multichannel seismic reflection and refraction data to determine sediment thickness. These data enable the United States to delineate its Extended Continental Shelf (ECS) along the Atlantic margin. The same data can also be used to understand large submarine landslides and therefore assess their potential tsunami hazard for infrastructure and communities living along the eastern seaboard. Supporting geophysical data were collected as marine magnetic data, gravity data, 3.5-kilohertz shallow seismic reflections, multibeam echo sounder bathymetry, and multibeam backscatter. 
The survey was conducted from water depths of approximately 1,500 meters to abyssal seafloor depths greater than 5,000 meters. Approximately 2,761 kilometers of multi-channel seismic data was collected along with 30 sonobuoy profiles.
This field program had two primary objectives: (1) to collect some of the data necessary to establish the outer limits of the U.S. Continental Shelf, or Extended Continental Shelf, as defined by Article 76 of the United Nations Convention of the Law of the Sea and (2) to study the sudden mass transport of sediments down the continental margin as submarine landslides that pose potential tsunamigenic hazards to the Atlantic and Caribbean coastal communities.

Peak marine sparker amplitude data from calibrated source and receive hydrophones collected in April 2021 offshore Santa Cruz, California (USGS field activity 2021-619-FA), and pressure vs. offset plots

Peak amplitude values recorded at source and receive hydrophones during a two-vessel marine sparker seismic survey conducted by the U.S. Geological Survey (USGS) in April of 2021 off the coast of Santa Cruz, California (USGS field activity 2021-619-FA) are presented. On the source vessel (R/V Parke Snavely; RVPS), near-field data were recorded using a broadband spherical reference Reson TC4034 hydrophone positioned 1-meter below the sparker source (either a SIG ELP790 or an Applied Acoustics Delta sparker) along seven depth site transects ranging between 25 and 600 meters. On the nearly stationary receive vessel (R/V San Lorenzo; RVSL), omnidirectional Cetacean Research CR3 hydrophones were positioned between 10- and 20-meters water depth below the vessel to record the far-field signal. Data are presented in csv format, accompanied by combined scatter plots per depth site and mean-filtered curve plots for visualization purposes.

Estimated Perennial Streams in Idaho, indexed to the NHDPlus

Perennial streams in Idaho have been
modeled using regression equations for 7-day, 2-year low flows (7Q2)
described in Wood and others (2009, U.S. Geological Survey Scientific
Investigations Report 2009-5015). The model produces "synthetic" streams
based on 10-meter resolution digitial elevation models that have been
processed to agree closely with 1:24,000-scale National Hydrography
Dataset flowlines. See Larger_Work_Citation report text for a complete
description of the modeling process. 
		
In this dataset, the synthetic stream lines have been indexed to the
NHDPlus Version 01_02 (schema version 1, data version 2). Points along
the synthetic streams where 7Q2 model estimates exceeded 0.1 cubic feet
per second were snapped to the NHDPlus 1:100,000-scale flowlines, and
then traced downstream using the NHDPlus network. The data are presented
in the form of a dBase-format event table. The traced line events
correspond to synthetic stream lines having PerCode values of 2 or
3.

EAARL Coastal Topography–Eastern Louisiana Barrier Islands, 09 March 2008: First Surface

ASCII XYZ point cloud data were produced from remotely sensed, geographically referenced elevation measurements by the U.S. Geological Survey (USGS). Elevation measurements were collected over some of the eastern Louisiana barrier islands in cooperation with the National Park Service (NPS), using the 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.

LANDFIRE 2016 Remap Existing Vegetation Height (EVH) Marshall 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).

Sustainable Seas Expedition Tracklines: Years 2000 and 2001

Pulley Ridge is a series of drowned barrier islands that extends almost 200 km in 60-100 m water depths. This drowned ridge is located on the Florida Platform in the southeastern Gulf of Mexico about 250 km west of Cape Sable, Florida. This barrier island chain formed during the initial stage of the Holocene marine transgression. These islands were then submerged and left abandoned near the outer edge of the Florida Platform. The southern portion of Pulley Ridge hosts zooxanthellate scleractinian corals, green, red and brown macro algae, and a mix of deep and typically shallow-water tropical fishes. This reef community is in unusually deep water, and its extent and the controls on its distribution were unknown. To address these questions scientists from the U.S. Geological Survey Coastal and Marine Geology Program in cooperation with scientists from the University of South Florida Department of Marine Sciences have completed a detailed mapping of the southernmost 35 km of Pulley Ridge. The area was mapped using multibeam bathymetry, sidescan-sonar imagery, and high-resolution seismic-reflection profiling to define the geologic framework on which the reef is established. Submersible dives, remotely operated vehicle (ROV) transects, and transects of bottom photographs and video were collected to identify the corals and to map their distribution. This extensive suite of data has been compiled and preliminary analysis of the data suggests that the reefs are not tied to the ridge system, but instead are more broadly distributed. Whether reef distribution is controlled by oceanographic conditions or by subtle differences in the substrate that overlies the barrier island system is unclear, and are topics of continued research.

LANDFIRE Remap Scott and Burgan Fire Behavior Fuel Model (FBFM40) Micronesia

LANDFIRE’s (LF) 2016 Remap (Remap) Scott and Burgan Fire Behavior Fuel Model 40 (FBFM40) product represents distinct distributions of fuel loadings found among surface fuel components (live and dead), size classes, and fuel types (Scott &amp; Burgan 2005). The fuel models are described by the most common fire carrying fuel type (grass, brush, timber, or slash), loading and surface area-to-volume ratio by size class and component, fuel bed depth, and moisture of extinction. FBFM40 contains more fuel models for every fuel type than Anderson Fire Behavior Fuel Model 13 (FBFM13), and the number of fuel models representing relatively High dead fuel moisture content is increased. In FBFM40 fuel models with an herbaceous component are dynamic, to simulate curing, rather than remaining constant. 
LF Remap used vegetation products and 10-years of disturbance data to create Fuel Vegetation Type (FVT), Fuel Vegetation Cover (FVC), and Fuel Vegetation Height (FVH) for disturbed areas to represent pre-disturbance scenarios in FBFM40. A combination of pre-disturbance and non-disturbance Existing Vegetation Type (EVT) are used to assign surface fuel models. FBFM40 was developed using the most recent 10 years of Annual Disturbance products and is a capable fuels product that calculates Time Since Disturbance (TSD) assignments for disturbed areas using an "effective year." For example, year 2020 fuels may be calculated for the year 2020. the new process considers all the existing disturbances included in LF Remap and adjusts the TSD for these to the effective year (2020 in the example), making the products "2020 capable fuels." More information about capable fuels can be found at https://www.landfire.gov/lf_remap.php.

Potential marine benthic habitat maps were constructed using multibeam echosounder (MBES) bathymetry and backscatter data. The habitats were based on substrate types and documented or "ground truthed" using underwater video images and seafloor samples obtained by the USGS. These maps display various habitat types that range from flat, soft, unconsolidated sediment-covered seafloor to hard, deformed (folded), or highly rugose and differentially eroded bedrock exposures.

CYM_250M_MER_NAD27.TIF - Cayman Trough GLORIA sidescan-sonar composite mosaic (MER, 250 m, Clarke 1866)

From October 22 to November 22, 1985 the U.S. Geological Survey (USGS) conducted a single to survey to ensonify the Cayman Trough. The survey took place over the coastal region of the spreading ridge and along one line to the eastern extremity of the Trough. As in earlier EEZ reconnaissance surveys, the USGS utilized the GLORIA (Geological LOng-Range Inclined Asdic) sidescan-sonar system to complete the geologic mapping. The collected GLORIA data were processed and digitally mosaicked to produce continuous imagery of the sea-floor. Two digital mosaics of a 2 degree by 2 degree area with a 50-meter pixel resolution were completed for the Cayman Trough south of the Cayman Islands.
