Publication_Date: 2013 Title: Shallow Geology, Sea-floor Texture, and Physiographic Zones of the Inner Continental Shelf from Nahant to Northern Cape Cod Bay, Massachusetts Series_Information: Series_Name: Open-File Report Issue_Identification: 2012-1157 Publication_Information: Publication_Place: Reston, VA Publisher: U.S. Geological Survey Online_Linkage: http://pubs.usgs.gov/of/2012/1157/ Description: Abstract: These data are qualitatively derived interpretive polygon shapefiles and selected source raster data defining surficial geology, sediment type and distribution, and physiographic zones of the sea floor from Nahant to Northern Cape Cod Bay. Much of the geophysical data used to create the interpretive layers were collected under a cooperative agreement among the Massachusetts Office of Coastal Zone Management (CZM), the U.S. Geological Survey (USGS), Coastal and Marine Geology Program, the National Oceanic and Atmospheric Administration (NOAA), and the U.S. Army Corps of Engineers (USACE). Initiated in 2003, the primary objective of this program is to develop regional geologic framework information for the management of coastal and marine resources. Accurate data and maps of seafloor geology are important first steps toward protecting fish habitat, delineating marine resources, and assessing environmental changes because of natural or human effects. The project is focused on the inshore waters of coastal Massachusetts. Data collected during the mapping cooperative involving the USGS have been released in a series of USGS Open-File Reports (http://woodshole.er.usgs.gov/project-pages/coastal_mass/html/current_map.html). The interpretations released in this study are for an area extending from the southern tip of Nahant to Northern Cape Cod Bay, Massachusetts. A combination of geophysical and sample data including high resolution bathymetry and lidar, acoustic-backscatter intensity, seismic-reflection profiles, bottom photographs, and sediment samples are used to create the data interpretations. Most of the nearshore geophysical and sample data (including the bottom photographs) were collected during several cruises between 2000 and 2008. More information about the cruises and the data collected can be found at the Geologic Mapping of the Seafloor Offshore of Massachusetts Web page: http://woodshole.er.usgs.gov/project-pages/coastal_mass/. Purpose: This backscatter intensity mosaic was created as a single continuous image of the acoustic reflectivity of the sea floor from Salisbury Beach to Northern Cape Cod 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 2012-1157.

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 smaller backscatter datasets that were processed and published as TIFF images (see Source Information for the individual input images). The only processing that was done to the source images was some color matching to make the individual images appear seamless. The individual source images are part of a larger mapping initiative: Gulf of Maine Mapping Initiative (GOMMI). The following website maintains a map that shows the extent of the high resolution surveys, the organizations that collected them, and a geographical name description of the area covered. http://www.gulfofmaine.org/gommi/coverage-map.php You can also download the source data listed in the source contribtutions from this page. Completeness_Report: This mosaic includes sidescan sonar and multibeam backscatter data collected during several cruises in the Gulf of Maine. 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 image quality of the backscatter data from the NOAA hydrographic surveys and NOAA/UNH/SAIC survey was lower than desired. 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 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.). The distribution format was modified in an attempt to be more consistent with other metadata files of the same data format. 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.
