Title:
Interpretation Showing the Distribution of Surficial Sediment in Quicks Hole, MA (H11076_SEDDIST.SHP, Geographic)
Abstract:
The U.S. Geological Survey (USGS), in cooperation with the National Oceanic and Atmospheric Administration (NOAA) and the Massachusetts Office of Coastal Zone Management (MA CZM), is producing detailed geologic maps of the coastal sea floor. Imagery, originally collected by NOAA for charting purposes, provide a fundamental framework for research and management activities along this part of the Massachusetts coastline, show the composition and terrain of the seabed, and provide information on sediment transport and benthic habitat. Interpretive data layers were derived from multibeam echo-sounder and sidescan sonar data collected in the vicinity of Quicks Hole, a passage through the Elizabeth Islands that extend in a chain southwestward off Cape Cod, Massachusetts. In June 2005, bottom photographs and surficial sediment data were acquired as part of a ground-truth reconaissance survey.

    Date: unknown (process 1 of 5)
    The geographic GeoTIFF image of the sidescan sonar and multibeam data from survey H11076 and the point data layer from grain-size analyses of sediments collected from this survey area were imported into the ArcView GIS project view. The distribution of surficial sediment was interpreted based on tonal changes in the sidescan sonar imagey, the bathymetry and textural analyses. The interpreted sediment distribution was outlined using the available graphic tools then converted to an ArcView shapefile for each environment. These shapefiles were merged into one file with the Geoprocessing Wizard extension. Person who carried out this activity:

    Edits to the metadata were made to fix any errors that MP v 2.9.30 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.). The source information was incomplete for both sources and had to be modified to meet the standard. The datum was specified as WGS 84, but the semi-major axis and flattening ratio were for NAD27. Assuming the datum name is correct, the numeric values were changed to match the datum name. An attribute enumerated domain was changed to unrepresentable - as more information was not available to thoroughly fill in enumerated information. 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. Person who carried out this activity:
