Description:
Abstract:
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.
Purpose:
This backscatter intensity mosaic was created as a single continuous image of the acoustic reflectivity of the sea floor for Buzzards Bay. 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. These data in both this final form and at the input resolutions helped define the sediment texture and distribution maps presented as interpretive data layers in USGS OFR 2014-1220.

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 the individual images to create a seamless backscatter mosaic. You can download the source data listed in the source contribtutions.
Completeness_Report:
This mosaic includes sidescan sonar and multibeam backscatter data collected during several cruises in Buzzards Bay. The input mosaics can be viewed by visiting the websites listed in the Source Information. Not all of the sources used to create the bathymetry grid were used here for the backscatter mosaic. The backscatter mosaic for the Woods Hole area (U.S. Geological Survey Open-File Report 2008-1004) was not included in the composite mosaic because it does not join with the overall mosaic. The backscatter mosaic can be downloaded separately (https://pubs.usgs.gov/of/2008/1004/)
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
In general, multibeam backscatter has a higher horizontal accuracy than sidescan sonar backscatter data, because there is no cable out or layback uncertainty associated with multibeam data. The horizontal accuracy of the multibeam backscatter (based on the accuracy listed in the input data) is assumed to be within 5 meters. The horizontal accuracy of sidescan sonar backscatter (also based on the accuracy reported in the input data reports) is assumed to be 10 meters. 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 describes the methods used for the acquisition of backscatter data for the Quicks Hole and Buzzards Bay area. Two 29-foot launches deployed from the NOAA Ship Thomas Jefferson were used to acquire bathymetric and backscatter data during 2004. The sidescan sonar data were acquired with a hull-mounted Klein 5250 system operating at 100 kHz.. The backscatter mosaic was later enhanced and is available through U.S. Geological Survey, Open-File Report 2008-1196. This enhanced image was used for the Buzzards Bay composite mosaic.

This report provided source backscatter for the area of Buzzards Bay 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. Sidescan-sonar (acoustic-backscatter) data were acquired with a Klein 3000 dual-frequency sidescan-sonar system (100 and 500 kHz). The 100 kHz data were used to create a backscatter mosaic. This mosaic was included in the Buzzards Bay composite mosaic.

This report provided the source backscatter data for Buzzards Bay in the area of Red Brook Harbor. Surveying was conducted aboard the R/V Rafael. Bathymetric data were collected with an SEA SWATHplus 234-kilohertz (kHz) interferometric sonar system. Acoustic backscatter, a measure of the intensity of returns from an insonified area of the sea floor, was recorded by the SEA SWATHplus interferometric sonar system.

This report provided the source backscatter for Buzzards Bay. The mapping was conducted during research cruises aboard the Megan T. Miller (2009 and 2010) and the Scarlett Isabella (2011). The NOAA Ship RUDE acquired bathymetric soundings in 2004 using a RESON SeaBat 8125 455-kHz multibeam-echosounder system. These data were not used in the composite backscatter image. All other surveys used a Klein 3000 dual-frequency sidescan-sonar (132 and 445 kHz).

Process_Description:
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.

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).
