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 data set contains a hillshaded-relief image produced from the Esri grid representing depth to the late Wisconsinan to early Holocene regressive unconformity (Ur) beneath Vineyard and western Nantucket Sounds (vnsurnavd88). 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.

Completeness_Report: All chirp and boomer seismic-reflection data collected within the study area 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. The grid contains three internal no data zones where it was not possible to make interpretations regarding the thicknesses of subsurface units. No seismic data were collected within the no data area coincident with Middle Ground shoal, thus precluding interpretation. The Knudsen Engineering Limited (KEL) Chirp 3202 data collected across the shallowest portions of L'Hommedieu and Hedge Fence Shoals provided inadequate combinations of resolution and penetration to support confident interpretation, due to shallow water depths and difficult to penetrate sandy, gravelly substrate. 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 Pendleton and others (2012; 2014), and Andrews and others (2014) 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.

These areas were surveyed with the RV Rafael in 2010 and 2011 during U.S. Geological Survey field activities 2010-047-FA, 2010-100-FA, and 2011-013-FA. 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.
