These maps were derived from interpretations of seismic-reflection profiles, high-resolution bathymetry, acoustic-backscatter intensity, bottom photographs, and surficial sediment samples. The interpretation of the seismic stratigraphy and mapping of glacial and Holocene marine units provided a foundation on which the surficial maps were created. This mapping is a result of a collaborative effort between the U.S. Geological Survey and the Massachusetts Office of Coastal Zone Management to characterize the surface and subsurface geologic framework offshore of Massachusetts. Purpose: This hillshaded-relief image was created as a single continuous surface for the sea floor of Vineyard and western Nantucket Sounds. These data helped define the sediment texture and distribution maps presented as interpretive data layers in USGS OFR 2016-1119 Time_Period_of_Content: Time_Period_Information: Range_of_Dates/Times: Beginning_Date: 1938 Ending_Date: 20110831 Currentness_Reference: ground condition Status: Progress: Complete Maintenance_and_Update_Frequency: None planned Spatial_Domain: Bounding_Coordinates: West_Bounding_Coordinate: -71.035443 East_Bounding_Coordinate: -70.428111 North_Bounding_Coordinate: 41.561895 South_Bounding_Coordinate: 41.319300 Keywords: Theme: Theme_Keyword_Thesaurus: USGS Metadata Identifier Theme_Keyword: USGS:41e3f146-32b7-4c60-8357-8f79262b1d85 Theme: Theme_Keyword_Thesaurus: None Theme_Keyword: U.S. Geological Survey Theme_Keyword: USGS Theme_Keyword: Coastal and Marine Geology Program Theme_Keyword: CMGP Theme_Keyword: Woods Hole Coastal and Marine Science Center Theme_Keyword: WHCMSC Theme_Keyword: Massachusetts Office of Coastal Zone Management Theme_Keyword: CZM Theme_Keyword: SEA Ltd Swathplus interferometric sonar Theme_Keyword: bathymetry Theme_Keyword: hillshade Theme_Keyword: GeoTIFF Image Theme_Keyword: lidar Theme_Keyword: multibeam bathymetry Theme_Keyword: seamless surface Theme_Keyword: U.S. Geological Survey Open-File Report 2006-1357 Theme_Keyword: U.S. Geological Survey Open-File Report 2008-1004 Theme_Keyword: U.S. Geological Survey Open-File Report 2009-1001 Theme_Keyword: U.S. Geological Survey Open-File Report 2011-1184 Theme_Keyword: U.S. Geological Survey Open-File Report 2012-1006 Theme_Keyword: U.S. Geological Survey Open-File Report 2013-1020 Theme_Keyword: RESON SeaBat 8125 Theme_Keyword: RESON SeaBat 8101 Theme_Keyword: National Oceanic and Atmospheric Administration Theme_Keyword: NOAA Theme_Keyword: Hydrographic Survey H11076 Theme_Keyword: Hydrographic Survey H11077 Theme_Keyword: Hydrographic Survey H11346 Theme_Keyword: Hydrographic Survey H11920 Theme_Keyword: Hydrographic Survey H11921 Theme_Keyword: U.S. Army Corps of Engineers Theme_Keyword: USACE Joint Airborne Lidar Bathymetry Technical Center of Expertise Theme: Theme_Keyword_Thesaurus: ISO 19115 Topic Category Theme_Keyword: oceans Theme_Keyword: geoscientificInformation Theme_Keyword: imageryBaseMapsEarthCover Theme_Keyword: elevation Theme: Theme_Keyword_Thesaurus: USGS Thesaurus Theme_Keyword: sea-floor characteristics Theme_Keyword: marine geophysics Theme_Keyword: computational methods Theme_Keyword: geospatial datasets Theme_Keyword: interferometric sonar Theme_Keyword: multibeam sonar Theme_Keyword: lidar Theme_Keyword: single-beam echo sounder Place: Place_Keyword_Thesaurus: None Place_Keyword: Vineyard Sound Place_Keyword: Nantucket Sound Place_Keyword: Atlantic Ocean Place_Keyword: Cape Cod Place_Keyword: Succonnesset Point Place_Keyword: Falmouth Place_Keyword: Woods Hole Place_Keyword: Gosnold Place_Keyword: Elizabeth Islands Place_Keyword: Nonamesset Island Place_Keyword: Naushon Island Place_Keyword: Pasque Island Place_Keyword: Nashawena Island Place_Keyword: Cuttyhunk Island Place_Keyword: Martha's Vineyard Place_Keyword: Aquinnah Place_Keyword: Menemsha Place_Keyword: Vineyard Haven Place_Keyword: Oak Bluffs Place_Keyword: Edgartown Place_Keyword: Cape Poge Place_Keyword: Lucas Shoal Place_Keyword: Middle Ground Shoal Place_Keyword: L'Hommedieu Shoal Place_Keyword: Succonnesset Shoal Place_Keyword: Hedge Fence Shoal Place_Keyword: Squash Meadow Shoal Stratum: Stratum_Keyword_Thesaurus: None Stratum_Keyword: Sea floor Access_Constraints: None Use_Constraints: Not to be used for navigation.

The National Oceanic and Atmospheric Administration (NOAA-NOS) is also an important partner and contributes hydrographic data that are integrated into the maps. The overall goal of this cooperative is to determine the geologic framework of the sea floor inside the 3-mile limit of State waters, using high-resolution geophysical techniques, sediment sampling, and sea-floor photography. These topographic and bathymetric source data related to the composite topographic and bathymetric grid are cited in detail in the source citation section of this metadata file. Online_Linkage: http://woodshole.er.usgs.gov/project-pages/coastal_mass/ Data_Quality_Information: Logical_Consistency_Report: This hillshaded-relief image was derived from the final output bathymetric DEM (vns10m_navd88) which was created from the best available bathymetric data for Vineyard and western Nantucket Sounds at the time of this publication. The composite bathymetry was created from several smaller bathymetry and lidar datasets that were processed and published in various formats and datums (see Source Information for the individual input data). NOAA single-beam sonar soundings and lead-line soundings were merged with the swath bathymetry and lidar. Bathymetric source datasets that were referenced to tidal datums (mean lower low water) were transformed to the North American Vertical Datum of 1988 (NAVD 88) using VDATUM (version 3.2). Individual datasets were imported into ArcGIS, evaluated for overlap and edited to subsets (generally on the basis of source quality, sounding density, and temporal relevance), compiled into a terrain model, then exported to an interpolated grid at 10 meters per pixel using the Natural Neighbors algorithm. Completeness_Report: The hillshaded relief was produced from lead-line soundings, single-beam sonar, swath interferometric, multibeam, and lidar data collected during several surveys in Vineyard and western Nantucket Sounds. The input grids can be downloaded by visiting the publications listed in the Source Information. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The horizontal accuracy of the source multibeam bathymetry (DGPS) is reported at +/- 3 meters. The horizontal accuracy of the swath bathymetry (DGPS and/or RTK-GPS) is conservatively estimated to be +/- 10 meters. The lidar data were collected to meet the +/- 3-meter accuracy specification. This composite topographic and bathymetric grid is assumed to be horizontally accurate to within 20 meters, as additional errors could have been introduced during resampling, vertical and horizontal reprojections, and mosaicking. Horizontal accuracy for lead-line and single-beam sonar soundings are not documented. See NOAA survey descriptive reports for individual survey positioning methods.
