Title:
Location of Sea-Floor Photographs Acquired During U.S. Geological Survey (USGS) Cruise 06005 (RAFA06005) in Great Round Shoal Channel, Offshore Massachusetts (RAF06005_BOTPHOTOS, 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 Great Round Shoal Channel, a passage through the shoals at the eastern entrance to Nantucket Sound, off Cape Cod, Massachusetts. In June 2006, bottom photographs and surficial sediment data were acquired as part of a ground-truth reconaissance survey.

Why was the data set created?

The purpose of this dataset is to release the locations and identifiers of 124 bottom photographs collected at 32 stations on topographic and backscatter data of the sea floor in Great Round Shoal, offshore Massachusetts. The photos were collected with a modified Van Veen grab modified to carry still and video camera systems (small SEABOSS) during USGS survey 06005, conducted June 26, 2006.

How was the data set created?

  1. From what previous works were the data drawn?
    Information unavailable from original metadata. (source 1 of 1)
    Information unavailable from original metadata., unknown, Information unavailable from original metadata..

    Other_Citation_Details:
    The orignal metadata only had source information time period of content. In order to pass the metadata harvester, the rest of the required source information fields were populated.
    Type_of_Source_Media: Information unavailable from original metadata.
    Source_Contribution: Information unavailable from original metadata.
  2. How were the data generated, processed, and modified?
    Date: 2006 (process 1 of 5)
    Navigation and time recorded on videotape were used to identify and register the still photographs. These data and identifiers were manually entered into spreadsheet software. Shapefiles were created in ArcView from the ASCII comma-delimited files exported from the spreadsheet application. 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 and had to be modified to meet the standard. The original metadata specified the WGS84 as the ellipsoid name, but that is in conflict with the horizontal datum name and other geodetic model paramters specified, so that was changed to Geodetic Reference System 80. 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:
