Bathymetry and sidescan-sonar imagery, originally collected by NOAA for charting purposes, provides 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 October 2008 NOAA completed hydrographic survey H11997 offshore in eastern Long Island Sound, and during May 2010 bottom photographs and surficial sediment data were acquired as part of a ground-truth reconnaissance survey 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 survey see http://quashnet.er.usgs.gov/data/2010/10015/ Purpose: To release an interpretation of bottom features based on bathymetry data collected during NOAA survey H11997 and sediment samples and bottom photography collected during USGS survey 2010-015-FA offshore in eastern Long Island Sound, in a geographic, WGS84 coordinate system. These data can be used to provide information on surface geology and sedimentary processes.

Multibeam bathymetry used in the interpretation were collected during 20080915 to 20081029. Source_Contribution: The original acoustic data acquired during NOAA survey H11997 aboard the NOAA ship Thomas Jefferson and the portion of the sediment samples and bottom photography collected during USGS survey 2010-015-FA that fall within the study area. Historical grain-size data used in the interpretation are from Poppe and others (1998). Process_Step: Process_Description: The geographic GeoTIFF image of the multibeam bathymetry data from survey H11997 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 geomorphology and relief in the bathymetry, and on the bottom photography and textural analyses. The individually interpreted features (rocky, sand waves, megaripples and ripples, dredge spoils, and two shipwrecks (indentified from online wreck reports and the descriptive report) were outlined using the available graphic tools then converted to an ESRI shapefile using ArcView 3.3. Polygons were were traced at a scale of 1:1,500, but union and subtraction edits were conducted at 1:5,000 to 1:8,500 scales. Therefore, use of this interpretation datalayer is not recommended at scales of less than 1:10,000.
