Title:
Outline of the Multibeam Bathymetry Data Collected During National Oceanic and Atmospheric Administration (NOAA) Survey H11922 (H11922OUTLINE, Geographic, WGS84)
Abstract:
The U.S. Geological Survey (USGS), in cooperation with the National Oceanic and Atmospheric Administration (NOAA), is producing detailed geologic maps of the coastal sea floor. Bathymetry, originally collected by NOAA for charting purposes, provides a fundamental framework for research and management activities off southern New England, shows the composition and terrain of the seabed, and provides information on sediment transport and benthic habitat. During July-August 2008 NOAA completed hydrographic survey H11922 west of Gay Head, Massachusetts, in Rhode Island Sound and during July and September 2010 bottom photographs and surficial sediment data were acquired as part of ground-truth reconnaissance surveys of this area. Interpretations were derived from the multibeam echo-sounder data and the ground-truth data used to verify them. For more information on the ground-truth surveys see http://quashnet.er.usgs.gov/data/2010/10033/ and http://quashnet.er.usgs.gov/data/2010/10005/

Why was the data set created?

To release an outline of the multibeam bathymetry data generated during NOAA survey H11922 west of Gay Head, Massachusetts, in Rhode Island Sound in geographic, WGS84. This outline also delineates the bounds of the sediment samples and bottom photography collected to verify the multibeam data.

How was the data set created?

  1. From what previous works were the data drawn?
    h11922_2mmb_geo.tif - derived from the first process step (source 1 of 1)
    The source information was incomplete and had to be modified to meet the standard. Assumed to be NOAA., unknown, Information unavailable from original metadata..

    Type_of_Source_Media: DVD-ROM
    Source_Contribution:
    The original acoustic data acquired during NOAA survey H11922 aboard the NOAA ship Thomas Jefferson.
  2. How were the data generated, processed, and modified?
    Date: 2010 (process 1 of 6)
    A geographic GeoTIFF of the H11922 multibeam bathymetry was imported into the ArcView 3.3 GIS project view. These acoustic data were outlined using the available graphic tools then converted to an ArcView 3.3 polygon shapefile. Person who carried out this activity:

    Date: 2010 (process 2 of 6)
    ArcGIS 9.2 was used to define the projection of the ESRI shapefile and to create the .prj file. XTools was used to calculate the area based on UTM Zone 18, WGS84 (UTM to get a more accurate area and WGS84 so the data were not reprojected during the calculation).

    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.). The source information was incomplete and had to be modified to meet the standard. 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:
