Title:
Interpretation of Bottom Features from National Oceanic and Atmospheric Administration (NOAA) Survey H11446 Offshore of Orient Point, New York (H11446INTERP, Geographic, WGS84)
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 Orient Point, New York. During April 2010, 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/2010/10010/.

Why was the data set created?

To release interpretations of bottom features based on sidescan-sonar and bathymetry data collected during NOAA survey H11446 and sediment samples and bottom photography collected during USGS survey 2010-010-FA offshore of Orient Point, New York, in a geographic, WGS84 coordinate system.

    The original acoustic data acquired during NOAA survey H11446 aboard the NOAA ship Thomas Jefferson collected from Sept. 22, 2008 to Oct. 21, 2008 and the sediment samples and bottom photography collected during USGS survey 2010-010-FA on Apr. 18, 2010.
  2. How were the data generated, processed, and modified?
    Date: 2010 (process 1 of 6)
    The geographic GeoTIFF images of the sidescan-sonar and multibeam data from survey H11446 and the point data layer from grain-size analyses of sediments collected from this survey area were imported into the ArcView 3.3 GIS project view. Bottom features were interpreted based on tonal changes in the sidescan-sonar imagery, the bathymetry, bottom photography, and textural analyses. The individually interpreted features (boulders and sand waves) were outlined using the available graphic tools then converted to an ESRI shapefile using ArcView 3.3.

    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:
