Title:
Outline of the Multibeam Bathymetry Data Collected During National Oceanic and Atmospheric Administration (NOAA) Survey H12013 (H12013OUTLINE.SHP, Geographic, WGS84)
Abstract:
The U.S. Geological Survey (USGS), in cooperation with the National Oceanic and Atmospheric Administration (NOAA) and the Connecticut Department of Energy and Environmental Protection (CT DEEP), is producing detailed geologic maps of the coastal sea floor. Bathymetry and sidescan-sonar imagery, originally collected by NOAA for charting purposes, provide a fundamental framework for research and management activities in Long Island Sound, shows the composition and terrain of the seabed, and provides information on sediment transport and benthic habitat. During April-May 2009 NOAA completed hydrographic survey H12013 offshore of the entrance to the Connecticut River, and during November 2009 and April 2010 bottom photographs and surficial sediment data were acquired as part of two ground-truth reconnaissance surveys of this area. Two interpretive data layers were derived from the multibeam echo-sounder and the ground-truth data used to verify them. For more information on the ground-truth surveys see: http://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=2009-059-FA and http://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=2010-010-FA

Why was the data set created?

To release an outline of the multibeam bathymetry data generated during NOAA survey H12013 off the entrance to the Connecticut River in northeastern Long Island Sound, in geographic, WGS84.

How was the data set created?

    Date: 2010 (process 1 of 6)
    The GeoTIFF image of the multibeam bathymetry from NOAA survey H12013 was imported into the ArcView 3.3 GIS project view. These acoustic data were outlined using the available graphic tools then converted to a polygon shapefile using ArcView 3.3. Person who carried out this activity:

    ArcGIS 9.2 was used to define the projection as geographic WGS84 of the ESRI shapefile and to create the .prj file using the ArcToolbox Define Projection tool. XTools (v. 5.2) 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 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.

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?
  2. How accurate are the geographic locations?
    Position of the ship and launches acquiring multibeam bathymetry were determined with differential GPS navigation systems.
