Title:
H11445OUTLINE.SHP: Outline of the Multibeam-Bathymetric and Sidescan-Sonar Data Collected During National Oceanic and Atmospheric Administration (NOAA) Survey H11445 (Geographic)
Abstract:
The U.S. Geological Survey (USGS), in cooperation with the Connecticut Department of Environmental Protection and National Oceanic and Atmospheric Administration (NOAA), is producing detailed geologic maps of the coastal sea floor. Imagery, originally collected by NOAA for charting purposes, provides a fundamental framework for research and management activities along this part of Long Island Sound, shows the composition and terrain of the seabed, and provides information on sediment transport and benthic habitat. Interpretive data layers were derived from the multibeam echo-sounder data and sidescan-sonar data collected north of Plum Island, New York. During November 2009, bottom photographs and surficial sediment data were acquired as part of a ground-truth reconnaissance survey. For more information on the ground-truth survey see <http://quashnet.er.usgs.gov/data/2009/09059/>.

Why was the data set created?

To release an outline of the multibeam-bathymetric and sidescan-sonar data generated during NOAA survey H11445 north of Plum Island, New York, in geographic.

How was the data set created?

  1. From what previous works were the data drawn?

    (source 1 of 1)
    Type_of_Source_Media: DVD-ROM
    Source_Contribution:
    The original multibeam-bathymetric and sidescan-sonar data acquired during NOAA survey H11445 aboard the NOAA ship Thomas Jefferson.

  2. How were the data generated, processed, and modified?

    Date: 2010 (process 1 of 2)
    The geographic H11445 sidescan-sonar mosaic and multibeam bathymetry GeoTIFF were imported into the ArcView 3.3 GIS project view. These data were outlined using the available graphic tools then converted to an ArcView 3.3 polygon shapefile.
