GAK_Q50.TIF - Gulf of Alaska U.S. EEZ GLORIA sidescan-sonar data mosaic (20 of 30) (LCC, 50 m, WGS84)

GLORIA data for the Gulf of Alaska Exclusive Economic Zone (EEZ) were acquired during five cruises over a four year period. The first cruise conducted in 1986 (F-1-86-GA) surveyed an area of the north-central mosaic area and covered an area of approximately 40,000 square kilometers (sq km). The second two cruises (F-8-88-AA, F-9-88-WG) were conducted in 1988. One of the 1988 cruises (F-8-88-AA) focused on a survey of the Aleutian Arc. The eastern most portion of that survey extended outside of the Aleutian Arc survey area and covered an area of approximately 52,000 square kilometers (sq km) of seafloor on the western edge of the Gulf of Alaska. The final two cruises (F-6-89-GA, F-7-89-EG) were completed in 1989. 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 seafloor. Thirty digital mosaics with a 50-meter pixel resolution were completed for the region.

SIR2016-5029_cfwgoshor_6: Flood Inundation Depth for a Flow of 39,900 at the Gage Coast Fork Willamette River at Goshen, Oregon

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.shp for information regarding this file. This represents the depth grid for the 39,900 
profile.

XBeach Bottom Friction Scenarios: Model Inputs and Results for Hurricane Ivan Spatially Varying Friction Scenario

Using the numerical model XBeach version 4926 (Roelvink and others, 2009), various bottom friction scenarios were simulated for hurricanes Ivan (2004) and Katrina (2005) at Dauphin Island, Alabama as described in Passeri and others, 2018. The XBeach model setup requires the input of a merged topographic and bathymetric digital elevation model (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. Model inputs and outputs in the form of topography and bathymetry are provided in this data release. For further information regarding model input generation and visualization of model output topography and bathymetry, refer to Passeri and others, 2018.

Archive of Chirp Subbottom Profile Data Collected in 2015 from the Northern Chandeleur Islands, Louisiana

From September 14 to 28, 2015, the U.S. Geological Survey (USGS) conducted a geophysical survey to investigate the geologic controls on barrier island evolution and medium-term and interannual sediment transport along the sand berm constructed in 2011 (offshore, at the northern end of the Chandeleur Islands, Louisiana) as mitigation of the Deepwater Horizon oil spill. This investigation is part of a broader USGS project, which seeks to better understand barrier island evolution over medium time scales (months to years). This publication serves as an archive of unprocessed, digital chirp subbottom data, survey trackline map, navigation files, geographic information system (GIS) data, and formal Federal Geographic Data Committee (FGDC) metadata. Processed subbottom profile images are also provided. The archived trace data are in standard Society of Exploration Geophysicists (SEG) SEG Y revision 0 format (Barry and others, 1975) and may be downloaded and processed with commercial or public domain software such as Seismic Unix (SU).
These data are available for viewing using GeoMapApp (http://www.geomapapp.org/) and Virtual Ocean (http://www.virtualocean.org/) multi-platform open source software.

Upper Klamath Basin Landsat Image for July 10, 2006: Path 44 Row 31

This subset of a Landsat-7 image shows part of the upper Klamath Basin. 
The original images were obtained from the U.S. Geological Survey Earth 
Resources Observation and Science Center (EROS). EROS is responsible 
for archive management and distribution of Landsat data products. The 
Landsat-7 satellite is part of an ongoing mission to provide quality remote 
sensing data in support of research and applications activities. The launch 
of Landsat-7 on April 15, 1999 marks the addition of the latest satellite to 
the Landsat series. The Landsat-7 satellite carries the Enhanced Thematic 
Mapper Plus (ETM+) sensor.  A mechanical failure of the ETM+ Scan Line 
Corrector (SLC) occurred on May 31, 2003, with the result that all Landsat 
7 scenes acquired from July 14, 2003 to present have been collected in
 'SLC-off' mode. More information on the Landsat program can be found 
online at http://landsat.usgs.gov/.

High-resolution multi-channel seismic-reflection data from USGS cruise 2018-641-FA, collected in south-central California in support of the Bureau of Ocean Energy Management (BOEM)-funded California Deepwater Investigations and Groundtruthing (Cal DIG I) offshore alternative energy project from 2018-08-29 to 2018-09-20

Multi-channel seismic (MCS) reflection data were collected as part of a geophysical survey aboard the NOAA Ship Rainier during two legs at sea, the first from 8/28/2018 to 9/7/2018 and the second from 9/10/2018 to 9/21/2018. The data were collected using a SIG 2-Mille minisparker and a 64-channel streamer, although the majority of the survey was conducted using a 56-channel setup due to technical issues with one 8-channel section early on in the survey. The MCS data were processed to post-stack time migration and include filtering and other noise removal corrections.

Sediment Grain-Size Data from Sediment Samples Collected in July 2013 from the Northern Chandeleur Islands, Louisiana (U.S. Geological Survey Field Activity Number 13BIM05)

As part of the Barrier Island Evolution Research (BIER) project, scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC) collected sediment samples from the northern Chandeleur Islands in July 2013. The overall objective of this project, which integrates geophysical (bathymetric, seismic, and topographic) and sedimentologic data, is to understand better the depositional and erosional processes that drive the morphologic evolution of barrier islands over annual to interannual timescales (1 to 5 years). Between June 2010 and April 2011, in response to the Deepwater Horizon oil spill, the State of Louisiana constructed a sand berm extending more than 14 kilometers (km) along the northern Chandeleur Islands platform. The construction of the berm provided a unique opportunity for scientists to investigate how this new sediment source interacts with and affects the morphologic evolution of the barrier-island system. Data collected from this study can be used to describe differences in the physical characteristics and spatial distribution of sediments both along the axis of the berm and also along transects across the berm and onto the adjacent barrier island. Comparison of these data with data from prior sampling efforts can provide information about sediment interactions and movement between the berm and the natural island platform, improving insight into short-term morphologic change and processes in this barrier-island system.
This data series serves as an archive of sediment data collected in July 2013 from the Chandeleur Islands sand berm and adjacent barrier-island environments. Data products, including descriptive core logs, core photographs and x-radiographs, results of sediment grain-size analyses, sample location maps, and Geographic Information System (GIS) data files with accompanying formal Federal Geographic Data Committee (FDGC) metadata, can be downloaded from https://pubs.usgs.gov/ds/894/ds894_data.html.

Sediment Grab Samples from the inner continental shelf off the northern Oregon and southern Washington coast from U.S. Geological Survey field activity 1998-014-FA

Two 21-day field operations were conducted in 1997 and 1998 in the estuaries and on the inner continental shelf off the northern Oregon and southern Washington coast. These cruises aboard the R/V Corliss were run in order to generate reconnaissance maps of the seafloor geology and the shallow subsurface stratigraphy using sidescan-sonar and seismic-reflection mapping techniques. The 1998 cruise also collected sediment grab samples, bottom photographs, and video images to verify the sidescan-sonar imagery and to document the seafloor geology. The combination of these data with previously collected sediment sample data (Robert, 1974; Nittrouer, 1978; and Smith et. al., 1980) has been used to define the extent and lithology of shelf sediments associated with the Columbia River littoral cell. This work is one component of a larger project studying the erosion of the Washington Oregon coasts and is being coordinated by the U.S. Geological Survey and the Washington State Department of Ecology. The reasons for collecting these data are to provide a regional synthesis of the offshore geology for this project and to support a wide variety of management decisions and to provide a basis for further process-oriented investigations.

Assessing the Effectiveness of Nourishment in Decadal Barrier Island Morphological Resilience: Model Inputs and Outputs (Storm_23_Elevations_N)

Using version 5527 of the XBeach numerical model (Roelvink and others, 2009), barrier island morphological change was simulated at Dauphin Island, Alabama (AL), for a 30-year forecast of multiple storms and sea level rise, considering scenarios of no-action and beach and dune nourishment as described in Passeri and others (2021). The two-dimensional XBeach model can be applied to barrier islands to solve for time-dependent topography and bathymetry. The XBeach model setup requires the input of topographic and bathymetric elevations at each grid cell. Model inputs and outputs in the form of topography and bathymetry at each grid cell are provided in this data release. For further information regarding model input generation and visualization of model output, refer to Passeri and others (2021).
