Title:
Interpretation of Bottom Features from National Oceanic and Atmospheric Administration (NOAA) Survey H11346 of Edgartown Harbor, MA (H11346_INTERP.SHP, Geographic, WGS84)
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, provides a fundamental framework for research and management activities along this part of the Massachusetts coastline, shows the composition and terrain of the seabed, and provides information on sediment transport and benthic habitat. Interpretive data layers were derived from the combined single-beam and multibeam echo-sounder data and sidescan-sonar data collected in the vicinity of Edgartown Harbor, Massachusetts. During August 2008 seismic-reflection profiles (Boomer and Chirp) were acquired, and during September 2008 bottom photographs and surficial sediment data were acquired as part of two ground-truth reconnaissance surveys.

Why was the data set created?

To release interpretations of bottom features based on sidescan-sonar and bathymetry data collected during NOAA survey H11346 and sediment samples and bottom photography collected during USGS survey RAFA08012 in Edgartown Harbor, Massachusetts, in a geographic, WGS84 coordinate system.

How was the data set created?

    Date: 2009 (process 1 of 6)
    The geographic GeoTIFF image of the sidescan-sonar and combined single-beam and multibeam data from survey H11346 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, bedforms (sand waves and megaripples), and shell beds) 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 2.9.30 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.). This file had a source contribution, but no other source information. This information 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.
