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 backscatter intensity mosaic was created as a single image of the acoustic reflectivity of the sea floor south and west of Martha's Vineyard and north of Nantucket, Massachusetts. 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 2018-1181.

Geologic mapping of the Massachusetts seafloor 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:
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. The source data (input mosaics) can be downloaded from the websited listed in the source contributions. Two of the datasets included in this mosaic used a Klein 3000 sidescan sonar to acquire the backscatter data, while the third dataset was collected using an interferometric system.
Completeness_Report:
This mosaic includes sidescan sonar and interferometric backscatter data collected during several cruises. The input mosaics can be viewed by visiting the websites listed in the source information. Only portions of some of the input survey data (i.e. Andrews and others, 2014) were used to create the composite backscatter mosaic. In other words, a bounding polygon was used to clip the final mosaic extent to the study area interest.
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 USGS Open-File 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 25-meters, as additional errors could have been introduced during resampling, horizontal projections, and mosaicking within PCI.

This publication provides the source sidescan sonar for the Martha's Vineyard Coastal Observatory area. Data were acquired with an L3-Klein Associates 3000 digital, dual-frequency, sidescan-sonar system (www.l-3klein.com). The sidescan-sonar was towed aft of the M/V Megan Miller. The resolution of the sidescan sonar mosaic was 5 meters per pixel.

This publication provides interferometric-sonar backscatter collected south of Martha's Vineyard and north of Nantucket. The data were collected aboard the M/V Scarlett Isabella in 2013 using a 234 kHz Systems Engineering and Assessment Ltd. (SEA) SWATHplus interferometric sonar. Small cross-track gaps in backscatter occur likely as a result of the ship pitching in rough seas. These gaps were not filled or interpolated. These data are 1-meter resolution

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. Although most of the small slivers and data gaps within the mosaic have a value of 0. No data is set to 255. Low-backscatter is represented by dark tones (low values) and high-backscatter is represented by bright tones (high values).
