Geologic, sediment texture, and physiographic zone maps characterize the sea floor south and west of Martha's Vineyard and north of Nantucket, Massachusetts. 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.
This data set contains a grid representing the elevation to the late Wisconsinan to early Holocene regressive unconformity (Ur) offshore of western and southern Martha's Vineyard and north of Nantucket. These data are useful for assessing relations between geologic framework and sea-bed morphology. The late Wisconsinan regressive unconformity (Ur) locally merges with Holocene transgressive unconformity (Ut) and defines the upper surface of glacial deposits.

Geologic Mapping of the Massachusetts Sea Floor
Woods Hole Coastal and Marine Science Center, Woods Hole, MA
U.S. Geological Survey, Coastal and Marine Geology Program
Geologic mapping of the Massachusetts seafloor is a cooperative effort that was initiated in 2003 by the U.S. Geological Survey (USGS) and the Massachusetts Office of Coastal Zone Management (CZM). 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. Any source data used to generate interpretative maps and data products are cited in detail in the source citation section of this metadata file.

Chirp seismic-reflection data collected during USGS Woods Hole Coastal and Marine Science Center field activities 2007-011-FA, 2011-004-FA, and 2013-003-FA were used to interpret the geologic framework offshore of western and southern Martha's Vineyard and north of Nantucket. All seismic reflection data used in this report were interpreted by the same person that conducted the processing steps. All interpretations were conducted in Kingdom Suite software, and hoizon gridding was conducted in ArcGIS. Any differences in collection vessel and system are noted in the source contributions.
All chirp seismic-reflection data collected within the study area during USGS Woods Hole Coastal and Marine Science Center field activities 2007-011-FA, 2011-004-FA, and 2013-003-FA were used to interpret the subsurface geologic units.
Navigational accuracy of the seismic-reflection data used for this interpretation was assumed to be ± 10 to 20 meters. Refer to seismic trackline metadata in Denny and others (2009), Ackerman and others (2016), and Andrews and others (2014) in the source information for specific seismic data acquisition parameters and accuracy reports. Additional navigational uncertainty in this interpretation arises from subjective digitizing of the seismic reflectors, sampling of the interpreted horizons at 20-m along track intervals prior to export from the seismic interpretation package. Total positional uncertainty is assumed to be within 50 meters.
The nominal vertical resolution of the chirp seismic-reflection systems is 0.5 meter. Additional uncertainty was introduced by converting depths measured in two-way travel time to meters using a constant speed of sound of 1500 m/s. The vertical accuracy also depends on the accuracy of the composite bathymetric grid. This structural surface was computed by subtracting the isopach of Holocene fluvial, estuarine (Qfe) and nearshore marine (Qmn)sediments from the composite bathymetric surface (Andrews and others, 2018) referenced to NAVD 88.

This report provided source geophysical data (sidescan-sonar, bathymetry, and seismic-reflection profiles) for the area south of Martha's Vineyard surrounding the Martha's Vineyard Coastal Observatory. The 2007 mapping was conducted on the M/V Megan T. Miller. High-resolution chirp seismic-reflection profiles were collected during U.S. Geological Survey field activity 2007-011-FA using an EdgeTech Geo-Star full spectrum sub-bottom (FSSB) system and SB-0512i towfish. Thorough descriptions of acquisition and processing parameters for the survey are provided by Denny and others (2009) in the report and seismic-reflection metadata. Shallow geologic framework and surficial geology were interpreted from post-processed chirp seismic-reflection profiles.

This report provided the composite bathymetry for the study area including offshore of southern Martha's Vineyard and north of Nantucket. Thorough descriptions of the merging and processing parameters are provided by Andrews and others (2018) in the metadata.
The isopach grid of post glacial sediments (MV_ACK_postGisopach.tif) was subtracted from the regional composite bathymetry DEM (Andrews and others, 2018) in ArcMap (10.5) using 'Raster Calculator', producing a DEM of the composite Ut/Ur unconformity relative to NAVD88. The DEM was filtered (Filter) using a low pass filter to smooth the grid, then clipped ('Clip' - data management) to the study area extent.
