Description:
Abstract:
Geologic, sediment texture, and physiographic zone maps characterize the sea floor of Vineyard and western Nantucket Sounds, 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 backscatter intensity mosaic was created as a single continuous image of the acoustic reflectivity of the sea floor of Vineyard and western Nantucket Sounds. Generally, higher backscatter values (light tones) represent rock, boulders, cobbles, gravel, and coarse sand. Lower values (dark tones) usually represent fine sand and muddy sediment. In this final form and at the input resolutions, these data helped define the sediment texture and distribution maps presented as interpretive data layers in USGS OFR 2016-1119.

Publication_Information:
Publication_Place: Woods Hole Coastal and Marine Science Center, Woods Hole, MA
Publisher: U.S. Geological Survey, Coastal and Marine Geology Program
Other_Citation_Details:
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. These topographic and bathymetric source data related to the composite backscatter image are cited in detail in the source citation section of this metadata file.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Image pixel values contain acoustic reflectivity values normalized to an 8-bit data range (0-255). Low-backscatter is represented by dark tones (low values) and high-backscatter is represented by bright tones (high values).
Logical_Consistency_Report:
This backscatter mosaic was created from several backscatter datasets that were processed and published as TIFF images (see Source Information for the individual input images). The source images were enhanced by stretching and color balancing, then the individual images were combined to create a seamless backscatter mosaic. You can download the source data listed in the source contributions.
Completeness_Report:
This mosaic includes sidescan sonar backscatter data collected during several cruises in Vineyard and western Nantucket Sounds. The input mosaics can be viewed by visiting the websites listed in the source information. Not all of the sources used to create the composite bathymetry grid (vns10m_navd88) were used for the backscatter mosaic.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The horizontal accuracy of sidescan sonar backscatter is assumed to be 10 meters according to the reports from which the input data were obtained. The mosaicking process in PCI used to combine all the source backscatter mosaics could introduce additional horizontal errors. This composite backscatter intensity mosaic is assumed to be horizontally accurate to within 50-meters, as additional errors could have been introduced during resampling, horizontal projections, and mosaicking within PCI.

This publication provides the source multibeam bathymetry for the Quicks Hole area. Two 29-foot launches deployed from the NOAA Ship Thomas Jefferson were used to acquire bathymetric and backscatter data during 2004. The multibeam bathymetric data were collected with hull-mounted 455-kHz RESON 8125 and 240-kHz RESON 8101 systems. The sidescan-sonar data were acquired with a hull-mounted Klein 5250 system operating at 100 kHz. Sediment samples and bottom photos were collected aboard the R/V Rafael with a modified Van Veen grab sampler and SEABOSS, respectively.

This report provided swath bathymetry for the area of Vineyard Sound surrounding the western Elizabeth Islands. Surveying was conducted aboard the RV Rafael in September 2010. Interferometric-sonar, sidescan-sonar, and chirp seismic-reflection systems were deployed simultaneously during the cruise. Bathymetric sounding data were collected with an SEA SWATHplus 234-kilohertz (kHz) interferometric sonar system. Sidescan-sonar (acoustic-backscatter) data were acquired with a Klein 3000 dual-frequency (100 and 500 kHz) sidescan-sonar system.

Overview_Description:
Entity_and_Attribute_Overview:
There are no attributes associated with this 8-bit GeoTIFF image. Image pixel values contain acoustic reflectivity values normalized to an 8-bit data range (0-255) with the data range 0-254 and 255 being no data. Although most of the small slivers and data gaps within the mosaic have a value of 254. Low-backscatter is represented by dark tones (low values) and high-backscatter is represented by bright tones (high values).
