HW3_Q63.TIF - Hawaii III - Northwestern Hawaii U.S. EEZ GLORIA sidescan-sonar data mosaic (11 of 22) (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). From 1989 through 1991, the USGS and IOS (Institute of Oceanographic Sciences, U.K.) scientists conducted several surveys within the EEZ off Hawaii. Six surveys during that time period focused on the northwestern Hawaii region. The results of these surveys were 22 digital mosaics of approximately of approximately a 2 degree by 2 degree area with a 50-meter pixel resolution.

October 2014 bathymetry collected near Dumbarton Bridge in south San Francisco Bay, California

Bathymetric survey data were collected in October 2014 just south of Dumbarton Bridge in south San Francisco Bay, California. A portion of the main channel was 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).

Contours Offshore of Tomales Point, California

This part of DS 781 presents data for the bathymetric contours for several seafloor maps of the Offshore of Tomales Point map area, California. The vector data file is included in "Contours_OffshoreTomalesPoint.zip," which is accessible from https://pubs.usgs.gov/ds/781/OffshoreTomalesPoint/data_catalog_OffshoreTomalesPoint.html. These data accompany the pamphlet and map sheets of Johnson, S.Y., Dartnell, P., Golden, N.E., Hartwell, S.R., Greene, H.G., Erdey, M.D., Cochrane, G.R., Watt, J.T., Kvitek, R.G., Manson, M.W., Endris, C.A., Dieter, B.E., Krigsman, L.M., Sliter, R.W., Lowe, E.N., and Chin, J.L. (S.Y. Johnson and S.A. Cochran, eds.), 2015, California State Waters Map Series—Offshore of Tomales Point, California: U.S. Geological Survey Open-File Report 2015–1088, pamphlet 38 p., 10 sheets, scale 1:24,000, https://doi.org/10.3133/ofr20151088.
10-m interval contours of the Offshore of Tomales Point map area, California, were generated from bathymetry data collected by California State University, Monterey Bay (CSUMB), by Fugro Pelagos, and by the U.S. Geological Survey. Mapping was completed between 2004 and 2010, using a combination of 200-kHz and 400-kHz Reson 7125, and 244-kHz Reson 8101 multibeam echosounders, as well as 234-kHz and 468-kHz SEA SWATHPlus phase-differencing sidescan sonars. These mapping missions combined to collect bathymetry from about the 10-m isobath to beyond the 3-nautical-mile limit of California's State Waters. Bathymetric contours at 10-m intervals were generated from a bathymetric surface model. The most continuous contour segments were preserved while smaller segments and isolated island polygons were excluded from the final output. Contours were smoothed via a polynomial approximation with exponential kernel (PAEK) algorithm using a tolerance value of 60 m. The contours were then clipped to the boundary of the map area. These data are not intended for navigational purposes.

Klamath Basin Restoration Agreement Off-Project Water Program Sub-basin Analysis Flow Statistics

The Klamath Basin Restoration Agreement (KBRA) was developed by a diverse group of stakeholders, 
Federal and State resource management agencies, Tribal representatives, and interest groups to provide 
a comprehensive solution to ecological and water-supply issues in the Klamath Basin. The Off-Project 
Water Program (OPWP), one component of the KBRA, has as one of its purposes to permanently provide 
an additional 30,000 acre-feet of water per year on an average annual basis to Upper Klamath Lake through 
“voluntary retirement of water rights or water uses or other means as agreed to by the Klamath Tribes, to 
improve fisheries habitat and also provide for stability of irrigation water deliveries.” The geographic area 
where the water rights could be retired encompasses approximately 1,900 square miles. The OPWP area 
is defined as including the Sprague River drainage, the Sycan River drainage downstream of Sycan Marsh, 
the Wood River drainage, and the Williamson River drainage from Kirk Reef at the southern end of Klamath 
Marsh downstream to the confluence with the Sprague River. Extensive, broad, flat, poorly drained uplands, 
valleys, and wetlands characterize much of the study area. Irrigation is almost entirely used for pasture.
    To assist parties involved with decisionmaking and implementation of the OPWP, the U.S. Geological 
Survey (USGS), in cooperation with the Klamath Tribes and other stakeholders, created five hydrological 
information products. These products include GIS digital maps and datasets containing spatial information 
on evapotranspiration, subirrigation indicators, water rights, subbasin streamflow statistics, and return-flow 
indicators.

Umpqua River Oregon Tidal PhotoMosaic 1939

The Umpqua River drains 12,103 square kilometers (4,673 square miles) in southwest Oregon before flowing
into the Pacific Ocean at Winchester Bay near the city of Reedsport. In cooperation with the Portland District 
of the U.S. Army Corps of Engineers (USACE), the USGS evaluated sediment transport and gravel storage 
along the downstream alluvial reaches of the North and South Umpqua Rivers and the entire mainstem 
Umpqua River. This includes the lower 46.8 kilometers (29.1 miles) of the North Umpqua River and the 
lower 122.6 kilometers (76.2 miles) of the South Umpqua River. 
		
The Umpqua River gravel transport study involved multiple analyses, including tracking patterns of historical 
channel change and estimation of a sediment budget. To support these analyses, digital channel maps were 
produced to depict channel and floodplain conditions along the Umpqua River system from different time periods.
		
GIS layers defining the active channel of the Umpqua River system were developed for three time periods: 
1939, 1967, and 2005. For the South Umpqua River and the 19 kilometers (12 miles) of the mainstem 
Umpqua River downstream from the confluence of the North and South Umpqua Rivers, GIS layers were 
also developed for the time periods 1994, 2000, and 2009.
		
For this project, the active channel was defined as area typically inundated during annual high flows, and 
includes the low-flow channel as well as side channels, islands, and channel-flanking gravel bars. The active 
channel datasets were developed by digitizing from aerial photographs. Aerial photographs from 1939 and 
1967 were scanned, rectified, and mosaiced for this project. Digital orthophotographs from 1994, 2000, 2005, 
and 2009 are publicly available (See metadata for each photograph set for more information on the rectification 
process and resolution of each dataset). Although our study area encompasses the Umpqua River and lower 
reaches of the North and South Umpqua Rivers, the extent of each dataset depended upon the underlying 
aerial photographs; for example, the 1967 photographs extend only as far downstream as floodplain kilometer 
7, whereas the 1939 and 2005 datasets extend to the mouth of the Umpqua River at the Pacific Ocean.

Projections of compound floodwater depths for the lower Nooksack River and delta, western Washington State

Computed flood depths associated with the combined influence of sea level position, tides, storm surge, and streamflow under existing conditions and projected future higher sea level and peak stream runoff are provided for the lower (Reach 1) of the Nooksack River and delta in Whatcom County, western Washington State. The flood-depth projection data are provided in a series of raster geotiff files. Flood-depth projections were computed using a system of numerical models that accounted for projected changes in climate forcing including sea level rise, storm surge, and stream discharge in the 2040s and 2080s based on the Coupled Model Intercomparison Project Phase 5 (CMIP5) Global Climate Model (GCM) projections. Additionally, the models were run with modifications to land surface elevations to represent proposed flood hazard reduction and salmon habitat restoration strategies (alternatives) under existing and future conditions. Variations of the models also simulated changes to the stream bed to reflect recently observed decadal-scale sedimentation patterns that affect flow conveyance and flood risk.

Autonomous Surface Vehicle Sidescan-sonar mosaic from Norman's Bar, Apalachicola Bay, Florida (ASV174.TIF)

These data were collected under a cooperative mapping program between the U.S. Geological Survey (USGS), the National Oceanic and Atmospheric Administration Coastal Services Center (NOAA\CSC), and the Apalachicola National Estuarine Research Reserve (NERR). The primary objectives of this program were to collect marine geophysical data to develop a suite of seafloor maps to better define the extent of oyster habitats, the overall seafloor geology of the bay and provide updated information for management of this resource. In addition to their value for management of the bay's oyster resources, the maps also provide a geologic framework for scientific research and the public.
High resolution bathymetry, backscatter intensity, and seismic profile data were collected over a 230 square kilometers of the floor of the bay. The study focused on the Apalachicola Bay and Western St. George Sound portions of the estuary mostly in depths &gt; 2.0 meters.

2021 New York State Lidar-Derived Dune Crest, Toe and Shoreline

The storm-induced Coastal Change Hazards component of the National Assessment of Coastal Change Hazards (NACCH) project focuses on understanding the magnitude and variability of extreme storm impacts on sandy beaches. Light detection and ranging (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 2021 New York State topographic 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.

Acoustic backscatter intensity from multibeam echosounder data collected offshore of Eureka, California

This 2-m-resolution acoustic backscatter data for the Offshore of Eureka, California, map area is part of USGS Data Series 781 (Golden and Cochrane, 2019). Backscatter data were collected by Fugro Pelagos in 2007 using a combination of 400-kHz Reson 7125, 240-kHz Reson 8101, and 100-kHz Reson 8111 multibeam echosounder systems. The data were post-processed by the California State University Monterey Bay Seafloor Mapping. The acoustic backscatter data are available as a georeferenced TIFF image. Within the final imagery, brighter tones indicate higher backscatter intensity, and darker tones indicate lower backscatter intensity. The intensity represents a complex interaction between the acoustic pulse and the seafloor, as well as characteristics within the shallow subsurface, providing a general indication of seafloor texture and composition. Backscatter intensity depends on the acoustic source level; the frequency used to image the seafloor; the grazing angle; the composition and character of the seafloor, including grain size, water content, bulk density, and seafloor roughness; and some biological cover. Harder and rougher bottom types such as rocky outcrops or coarse sediment typically return stronger intensities (high backscatter, lighter tones), whereas softer bottom types such as fine sediment return weaker intensities (low backscatter, darker tones).

Video transects of the sea floor on Stellwagen Bank during U.S. Geological Survey field activity 2017-044-FA, aboard the R/V Auk, September 12-14, 2017

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 57 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.

EAARL-B Submerged Topography—Barnegat Bay, New Jersey, post-Hurricane Sandy, 2012–2013

American Standard Code Information Interchange XYZ and binary point-cloud data, as well as a digital elevation model for part of Barnegat Bay, New Jersey, post-Hurricane Sandy (October 2012 hurricane), were produced from remotely sensed, geographically referenced elevation measurements by the U.S. Geological Survey. Elevation measurements were collected over the area using the second-generation Experimental Advanced Airborne Research Lidar, 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 25 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.
