Geologic, sediment texture, and physiographic zone maps characterize the sea floor of Buzzards Bay, 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 depth to the top of glacial deposits. These data are useful for assessing relations between geologic framework and sea-bed morphology. The top of the glacial deposit surface is defined by the Ur/Ut unconformity. The late Wsconsinan regressive unconformity (Ur) and where Ur merges with the Holocene transgressive unconformity (Ut) defines the upper surface of glacial deposits.

Chirp seismic-reflection data collected during USGS Woods Hole Coastal and Marine Science Center field activities 2009-002-FA, 2010-003-FA, 2010-004-FA, 2011-004-FA, and 2011-047-FA and boomer seismic-reflection data during USGS Woods Hole Coastal and Marine Science Center field activities 2010-047-FA and 2010-100-FA were used to interpret the geologic framework of Buzzards Bay
All chirp and boomer seismic-reflection data collected during USGS Woods Hole Coastal and Marine Science Center field activities 2009-002-FA, 2010-003-FA, 2010-004-FA, 2010-047-FA, 2010-100-FA, 2011-004-FA , and 2011-013-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 Pendleton and others (2012; 2014), Turecek and others (2012),and Ackerman and others (2013) 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.
The nominal resolution of the chirp seismic-reflection systems is 0.5 meter. This structure map was calculated from sediment thickness, which relies on using a velocity of sound in sediment. We used 1500 m/s. The vertical accuracy also depends on the accuracy of the composite bathymetric grid. Sediment thickness was subtracted from the bathymetric surface referenced to NAVD 88.

This report provided source geophysical (sidescan, bathymetry, and seismic-reflection profiles) for the area of Buzzards Bay surrounding the western Elizabeth Islands. High-resolution chirp seismic-reflection profiles were collected during U.S. Geological Survey field activity 2010-003-FA using an EdgeTech Geo-Star full spectrum sub-bottom (FSSB) system and SB-424 towfish. Thorough descriptions of acquisition and processing parameters for the survey are provided by Pendleton and others (2012) in the methods section and seismic-reflection metadata. Shallow geologic framework and surficial geology were interpreted from post-processed chirp seismic-reflection profiles.

This report provided the source geophysical (sidescan, bathymetry, and seismic-reflection profiles) for Buzzards Bay in the area of Naushon Island and seismic-reflection profiles in northeast Buzzards Bay. These areas were surveyed with the RV Rafael in 2010 and 2011 during U.S. Geological Survey field activities 2010-047-FA and 2011-013. In 2010, seismic-reflection data were acquired with a boomer source and GeoEel 8-channel streamer. In 2011, high-resolution chirp seismic data were collected using a dual frequency (3.5 and 200 kHz) Knudsen Engineering Limited (KEL) Chirp 3202 system. Thorough descriptions of acquisition and processing parameters for each survey are provided by Pendleton and others (2014) in the methods section and seismic-reflection metadata. Shallow geologic framework and surficial geology were interpreted from post-processed chirp seismic-reflection profiles.
Chirp and boomer seismic-reflection data were interpreted using Landmark SeisWorks 2D (R5000) 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 was merged with the base of dredge spoil deposits. This surface was subtracted from the Ur/Ut (postglacial) unconformity. The isochron thickness (including zero values) was sampled at a 20-meter along track interval and exported from SeisWorks as ASCII text.

Two-way travel time thickness was converted to thickness in meters with ArcMap (9.3.1) Spatial Analyst Tools "Raster Calculator". A velocity of 1500 m/s was used. This grid was added to the thickness of dredge spoil grid. The resulting grid was subtracted from the composite bathymetry grid (NAVD 88) to produce the elevation of Ur grid. This grid was clipped using ArcMap 9.3.1 Spatial Analysist Tools Extract by Mask to clip the grid to boundary of the seismic survey data.

Edits to the metadata were made to fix any errors that MP v 2.9.32 flagged. 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.). Empty fields were deleted. Links to the data were fixed. 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.
