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.

Composite sidescan-sonar mosaic collected by the U.S. Geological Survey in Woods Hole, MA offshore of the Elizabeth Islands, MA, 2010 (2010-003-FA_SSmosaic_BuzzardsBay.tif, UTM Zone 19N GeoTIFF)

These data were collected under a cooperative agreement between the Massachusetts Office of Coastal Zone Management (CZM) and the U.S. Geological Survey (USGS), Coastal and Marine Geology Program, Woods Hole Coastal and Marine Science Center (WHCMSC). Initiated in 2003, the primary objective of this program is to develop regional geologic framework information for the management of coastal and marine resources. Accurate data and maps of seafloor geology are important first steps toward protecting fish habitat, delineating marine resources, and assessing environmental changes due to natural or human impacts. The project is focused on the inshore waters of coastal Massachusetts, primarily in water depths of 2-30 meters. Data collected for the mapping cooperative have been released in a series of USGS Open-File Reports (&lt;http://woodshole.er.usgs.gov/project-pages/coastal_mass/&gt;). The data collected in this study area located around the western extent of the Elizabeth Islands includes high resolution bathymetry, acoustic-backscatter intensity, seismic-reflection, and navigation data. These data were collected during a nearshore cruise in September 2010 onboard the R/V Rafael using the following equipment: an SEA Ltd SwathPlus interferometric sonar (234 kHz), Klein 3000 dual frequency sidescan sonar, an Edgetech 424 chirp subbottom profiling system, and 4 GPS antennae. More information about the cruise conducted as part of the project: Geologic Mapping of the Seafloor Offshore of Massachusetts can be found on the Woods Hole Coastal and Marine Science Center Field Activity webpage:

SIR2016-5029_cfwgoshor_2b: Flood Inundation Depth for a Flow of 15,000 cfs at the Gage Coast Fork Willamette River at Goshen, Oregon (Area of Uncertainty)

The domain of the model is as follows: Row River from Dorena dam to the confluence with the Coast Fork; 
Coast Fork from Cottage Grove dam to the confluence with the Middle Fork; Silk Creek from River Mile 1.7
 to the confluence with the Coast Fork. The basis for these features is the Willamette Flood Insurance Study – 
Phase One (2013). The hydraulics and hydrology for the FIS were reused in the production of these polygons; 
the reports and information associated with the FIS are applicable to this product. The Digital Elevation Model 
(DEM) utilized for the Willamette FIS submittal was produced by combining multiple overlapping topographic 
surveys for the Middle Fork and Coast Fork of the Willamette River. This DEM was created from four sources:
LiDAR of the Springfield area that was flown in 2008, LiDAR of Silk Creek that was flown in 2011, LiDAR of 
Fall Creek that was flown in 2012, and photogrammetry of the Middle Fork and Coast Fork of the Willamette 
River that was flown in 2004. In areas where no high-resolution elevation data were available, USGS National 
Elevation Dataset (NED) data were used to supplement the DEM. The shapefiles Hi_Res_Extents.shp and 
Low_Res_Extents.shp define the limits of these areas. The horizontal datum of the DEM is NAD 1983 State 
Plane-Oregon South HARN with units of International Feet (NAD83). The vertical datum of the elevation model 
is NAVD 1988 with units of international feet (NAVD-88). In addition, some areas show surveyed bathymetry 
within the channel. These can be noted by the sharp increase in apparent depth, creating a stripe across the
depth grid when compared to the LiDAR data, which represents the water surface elevation at the time of the 
aerial data collection. Bridge decks are generally removed from DEMs as standard practice. Therefore, these 
features may be shown as inundated when they are not. An effort to clip flood extents on bridge decks was 
made, but judgement should be used when estimating the usefulness of a bridge during flood flow. Comparing 
the bridge to the surrounding ground can be more informative in this respect than simply looking at the bridge 
itself. The features and depth grids stop as the Coast Fork approaches the Middle Fork on the northern end of 
the reach. See cfwgoshOR_breach.shp for information regarding this file. This represents the depth grid for the 
15,000 cfs profile.

Digital vector bathymetric/topographic contours of the sea floor in the Stellwagen Bank National Marine Sanctuary region (bathy.shp)

This data set contains the sea floor topographic contours generated from a multibeam sonar survey of the Stellwagen Bank National Marine Sanctuary region off Boston, Massachusetts, 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. The multibeam data were collected utilizing a Simrad Subsea EM 1000 Multibeam Echo Sounder (95 kHz) that is permanently installed in the hull of the Creed.

Storm-Impact Scenario XBeach Model Results – Scenario 12 Digital Elevation Model (DEM) Grid

The numerical model XBeach (version 4937) was used to investigate how different storm scenarios impact the sediment berm constructed offshore of the Chandeleur Islands and adjacent areas. The XBeach model solves coupled 2-dimensional, horizontal wave propagation equations to predict flow, sediment transport, and bottom changes for varying spectral wave and flow boundary conditions (Roelvink and others, 2009 ). The XBeach model setup requires the input of a merged topographic and bathymetric DEM, and inputs of wave spectra (based on significant wave height, peak wave period, and wave direction) and water level (tide and surge) time series at the seaward model boundary that span the duration of each storm bin. The Xbeach model input and output of topography and bathymetry resulting from simulation of storm-impact scenarios at the Chandeleur Islands, LA, as described in USGS Open-File Report 2017–1009 are provided via a USGS data release (storm scenario bins where no events were observed are excluded). For further information regarding model input generation and visualization of model output topography and bathymetry, refer to Mickey and others (2017).

2009 Florida USACE Lidar-Derived Dune Crest, Toe and Shoreline

The Storm-Induced Coastal Change Hazards component of the National Assessment of Coastal Change Hazards project focuses on understanding the magnitude and variability of extreme storm impacts on sandy beaches. Lidar-derived beach morphologic features such as dune crest, toe and shoreline help define the vulnerability of the beach to storm impacts. This dataset defines the elevation and position of the seaward-most dune crest and toe and the mean high water shoreline derived from the 2009 Florida U.S. Army Corps of Engineers (USACE) lidar survey. Beach width is included and is defined as the distance between the dune toe and shoreline along a cross-shore profile. The beach slope is calculated using this beach width and the elevation of the shoreline and dune toe.

KP_Q04.TIF - Kingman Reef and Palmyra Atoll U.S. EEZ GLORIA sidescan-sonar data mosaic (4 of 7) (LCC, 50 m, WGS84)

In 1984, the U.S. Geological Survey (USGS), Office of Marine Geology, launched a program using the Geological LOng-Range Inclined Asdic (GLORIA) sidescan-sonar system to study the entire U.S. Exclusive Economic Zone (EEZ). For a one month period beginning 24 February 1991 and finishing on 25 March 1991, USGS and IOS (Institute of Oceanographic Sciences, U.K.) scientists conducted a single survey within the Kingman Reef and Palmyra Atoll U.S. EEZ. The survey focused on the U.S. Exclusive Economic Zone surrounding the Kingman Reef and Palmyra Atoll. Unfortunately, the southwestern third of this EEZ was not imaged. The results of this single survey were 7 digital mosaics with a 50-meter pixel resolution.
