Description:
Abstract:
These data were collected in a collaboration between the Woods Hole Oceanographic Institution and the U.S. Geological Survey (USGS). The primary objective of this program was to collect baseline bathymetry for Muskeget Channel, Massachusetts, and identify areas of morphologic change within and around the channel. Repeat surveys in select areas were collected one month apart to monitor change. These data were collected to support an assessment of the effect on sediment transport that a tidal instream energy conversion facility would have within Muskeget Channel. Accurate data and maps of sea-floor topography are important first steps in monitoring bedform migration, fish habitat, marine resources, and environmental changes due to natural or human impacts. The data include high-resolution bathymetry, acoustic-backscatter intensity, sound velocity in water, and navigation data. These data were collected during two surveys between October 2010 and November 2011 onboard the research vessel (RV) Rafael using an SEA Ltd. SwathPlus interferometric sonar (234 kilohertz). More information about the cruise can be found on the Woods Hole Coastal and Marine Science Center field activity Web page at <http://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=2010-072-FA>
Purpose:
This GeoTIFF (Tagged Image File Format) contains acoustic backscatter data that were collected in October 2010. These data are used to define the seafloor morphology surrounding Muskeget Channel, Massachusetts

Data_Quality_Information:
Attribute_Accuracy:
Logical_Consistency_Report:
Although backscatter was not an essential data source for the Muskeget Channel mapping program, they are provided here as supplemental data because they are collected simultaneous with interferometric bathymetry data and are relatively easy to process and release.
Completeness_Report:
Interferometric backscatter collected during the first survey of 2010-072-FA were used to create this mosaic. Data from the second survey (on 20101119), which reoccupied lines from the first survey, were not included in this mosaic. Any change in backscatter between surveys 1 and 2 would be nearly negligle in a 1-meter mosaic and outside the scope of the goals of this survey.

Horizontal_Positional_Accuracy_Report:
The navigation for these data was acquired with a Coda Octopus F180 Differential Global Positioning System + Wide Area Augmentation System (DGPS+WAAS); they are accurate to + or - 1 to 2 meters, horizontally. All DGPS data are referenced to WGS 84, and vertical distance between the pole-mounted interferometric sonar head, 0.5m below the sea surface, and the DGPS antenna located on the same pole on the bow of the R/V Rafael, 2.5 m above the sea surface, are corrected.

Backscatter data were acquired with a SEA Swathplus interferometric sonar (234 kHz) mounted on the bow of the R/V Rafael of Woods Hole, MA. The data were acquired with SwathPlus Software (versions: 3.7.10). Tracklines are spaced 70-m apart.
Source_Citation_Abbreviation: USGS
Process_Step:
Process_Description:
Swathplus raw backscatter files (.sxr's) were imported into Chesapeake Technology Inc.'s SonarWiz software (version 5). The water-bottom was identified using a user-assisted bottom tracking algorithm. After all the altitudes were correctly defined, an empirical gain normalization (EGN) function for backscatter (Finlayson, 2010) was used to interpolate across data gaps at nadir and enhance the visual display of the data by optimizing the dynamic range of backscatter intensity. SonarWiz was also used to mosaic the lines into a single backscatter file, then export the mosaic to a 1-meter 24-bit GeoTIFF image.

Overview_Description:
Entity_and_Attribute_Overview:
There are no attributes associated with a GeoTIFF image. Image pixel values contain acoustic reflectivity values normalized to an 24-bit data range. Low-backscatter is represented by dark tones (low values) and high-backscatter is represented by bright tones (high values). The background color is set to 0-0-0 and can be turned off without removing data values.
