Description:
Abstract:
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.
Purpose:
This dataset describes sea-floor geology Vineyard along the western and southern seafloor offshore of Martha’s Vineyard and north of Nantucket. Polygons are used to indicate the areal distribution of sea-floor outcrop for sub-surface stratigraphic units interpreted in high-resolution seismic reflection data. These data are useful for assessing relations between geologic framework, sea-bed morphology, and sediment textural trends.

Public domain data from the U.S. Government are freely redistributable with proper metadata and source attribution. Please recognize the U.S. Geological Survey (USGS) as the source of this information. Additionally, there are limitations associated with qualitative surficial geologic mapping interpretations. Because of the scale of the source geophysical data and the spacing of samples, not all changes in sea floor geology are captured. The data were mapped between 1:8,000 and 1:25,000, but the recommended scale for application of these data is 1:25,000.

Geologic mapping of the Massachusetts inner continental shelf 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.

Data_Quality_Information:
Logical_Consistency_Report:
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. Because of the scale and line spacing of the source seismic profiles, not all changes in seafloor geology are captured. The boundaries of polygons are inferred between seismic lines, and polygon boundaries should be considered an approximation of the location of a change in geology. Further, some boundaries were refined using backscatter and bathymetry changes at the seafloor. A constant seismic velocity of 1,500 m/s was assumed for all profiles to compute depth in meters, through water and all sediment types, which may result in inaccurate depths of stratigraphic units.
Completeness_Report:
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 surficial geologic units. All of the interpretive layer bounds in this report are a little short of the data bounds in western Vineyard Sound, this is because this dataset abuts the interpretive layers of Baldwin and others (2016), and are not redundant with that interpretation.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
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 10-m along track intervals prior to export from the seismic interpretation package.

This report provided source geophysical data (sidescan-sonar bathymetry, and seismic-reflection profiles) for the majority of this study including offshore of southern Martha's Vineyard and north of Nantucket. These areas were surveyed with the Scarlett Isabella 2013 during U.S. Geological Survey field activity 2013-003-FA. Seismic-reflection data were collected using an EdgeTech Geo-Star FSSB subbottom profiling system and an SB-0512i towfish. Thorough descriptions of acquisition and processing parameters for each survey are provided by Ackerman and others (2016) in the methods section and seismic-reflection metadata. Shallow geologic framework and surficial geology were interpreted from post-processed chirp seismic-reflection profiles.
Process_Step:
Process_Description:
Chirp and boomer seismic-reflection data were interpreted using The IHS Kingdom Suite (version 8.8 - 64 bit) seismic interpretation software. Interpretation consisted of identifying and digitizing erosional unconformities defining the boundaries between Holocene, Pleistocene, and pre-Quaternary seismic units, and digitizing the extent over which each of the defined sub-surface seismic units crops out on the sea floor. The digitized sea-floor outcrop extents for each seismic unit were sampled at a 10-meter along track interval and exported from Kingdom as ASCII text. The resultant text file was imported into ArcMap (10.5) as point features (easting, northing, seismic unit) using the 'Add XY data' function, then saved as a point shapefile (UTM, Zone 19N, WGS84).

Process_Description:
A polygon feature class of the seismic-reflection survey area was created from the sediment texture feature class in ArcCatalog 10.5. A new attribute field named 'Geology' was added to the attribute table and fields associated with sediment texture were deleted. The point shapefile containing the along track extents of seismic unit outcrop was then used to guide the surficial geology interpretation (using editor processes 'cut polygon feature', 'intersect', 'merge', and 'clip' in ArcMap 10.5). As new polygons were created, the 'Geology' attribute field was populated with the appropriate geologic unit label. Polygon editing was done at scales between 1:8,000 and 1:25,000, depending on the size of the outcrop area.

Codeset_Name:
Qdf - Pleistocene glaciofluvial (outwash) - Stratified drift composed of sand and gravel that produce vertically laminated, roughly horizontal to broadly undulating reflectors, cut and fill structures, and zones of acoustic transparency. Underlies Ut and Ur, and typically overlies glaciolacustrine (Qdl) and glacial till (Qdt).

Codeset_Name:
Qfe - Holocene fluvial and estuarine - Fluvial sands and gravels, and estuarine sands and muds (locally > 11 m thick) that fill incised fluvial valleys. Produces vertically laminated, horizontal to concave-up reflectors and zones of acoustic transparency; local indications of cut-and-fill. Bounded above and below by Ut and the regressive unconformity (Ur), respectively.

Codeset_Name:
Qmn - Holocene nearshore marine - Mostly sandy deposits (typically less than 2 m but up to 17 m thick) that form tidal shoals and sand waves , and beaches and bars locally along their nearshore margins. Generally acoustically transparent with faint, flat-lying reflectors, except within the tidal shoals, where internal reflectors are indicative of morphologic evolution. Overlies transgressive unconformity (Ut) and grades to Qmd westward toward Rhode Island Sound.
