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 https://cmgds.marine.usgs.gov/fan_info.php?fan=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 Time_Period_of_Content: Time_Period_Information: Multiple_Dates/Times: Single_Date/Time: Calendar_Date: 20101012 Single_Date/Time: Calendar_Date: 20101013 Single_Date/Time: Calendar_Date: 20101014 Single_Date/Time: Calendar_Date: 20101019 Currentness_Reference: ground condition Status: Progress: Complete Maintenance_and_Update_Frequency: None planned Spatial_Domain: Bounding_Coordinates: West_Bounding_Coordinate: -70.505304 East_Bounding_Coordinate: -70.394974 North_Bounding_Coordinate: 41.417575 South_Bounding_Coordinate: 41.291845 Keywords: Theme: Theme_Keyword_Thesaurus: USGS Metadata Identifier Theme_Keyword: USGS:fe352da6-f7f5-4f57-8b34-3df5ff2bf8d3 Theme: Theme_Keyword_Thesaurus: None Theme_Keyword: U.S. Geological Survey Theme_Keyword: USGS Theme_Keyword: Woods Hole Coastal and Marine Science Center Theme_Keyword: WHCMSC Theme_Keyword: Coastal and Marine Geology Program Theme_Keyword: CMGP Theme_Keyword: backscatter Theme_Keyword: SEA Ltd Swathplus interferometric sonar Theme_Keyword: interferometric backscatter Theme_Keyword: GeoTIFF image Theme_Keyword: grey scale Theme_Keyword: composite image Theme_Keyword: WHCMSC field activity report number 2010-072-FA Theme_Keyword: mosaic Theme: Theme_Keyword_Thesaurus: ISO 19115 Topic Category Theme_Keyword: oceans Theme_Keyword: geoscientificInformation Theme_Keyword: imageryBaseMapsEarthCover Theme: Theme_Keyword_Thesaurus: USGS Thesaurus Theme_Keyword: sea-floor acoustic reflectivity Theme_Keyword: image mosaics Theme_Keyword: interferometric sonar Theme_Keyword: marine geophysics Theme_Keyword: geospatial datasets Place: Place_Keyword_Thesaurus: None Place_Keyword: North America Place_Keyword: Atlantic Ocean Place_Keyword: Massachusetts Place_Keyword: United States Place_Keyword: Muskeget Channel Place_Keyword: Vineyard Sound Place_Keyword: Martha's Vineyard Place_Keyword: Nantucket Sound Place_Keyword: Chappaquiddick Island Place_Keyword: Edgartown Place_Keyword: Mutton Shoal Place_Keyword: Muskeget Island Place_Keyword: Nantucket Island Place_Keyword: Tuckernuck Island Place_Keyword: Wasque Point Place_Keyword: Cape Poge Place_Keyword: Katama Bay Place_Keyword: Hawes Shoal Place_Keyword: Norton Shoal Place_Keyword: Bass Ledge Place_Keyword: Shovelful Shoal Place_Keyword: Wasque Shoal Access_Constraints: None Use_Constraints: Public domain data from the U.S. Government are freely redistributable with proper metadata and source attribution.

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. Positional_Accuracy: Horizontal_Positional_Accuracy: 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.

The data were acquired with SwathPlus Software (versions: 3.7.10). Tracklines are spaced 70-m apart. 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.

This is necessary to enable the metadata to be successfully harvested for various data catalogs. In some cases, this meant adding text "Information unavailable" or "Information unavailable from original metadata" for those required fields that were left blank. Other minor edits were probably performed (title, publisher, publication place, etc.). Attempted to modify http to https where appropriate. Added the DOI link in the Identification section - both as the first link and as part of the Larger Work citation. Removed LIDAR bounding coordinates - an artifact of Esri and MP processing. The source information was incomplete and had to be modified to meet the standard. The metadata date (but not the metadata creator) was edited to reflect the date of these changes. The metadata available from a harvester may supersede metadata bundled within a download file. Compare the metadata dates to determine which metadata file is most recent.
