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 collected north of Duck Pond Point, New York. During April and May 2010, bottom photographs and surficial sediment data were acquired during 2 cruises as part of USGS ground-truth reconnaissance surveys of this area. For more information on the ground-truth surveys see and . Purpose: The purpose of these data is to provide the navigation for OSV Bold cruise 2010-015-FA as recorded from an Ashtech G12 Global Positioning System (GPS) Sensor. This provides an archive of the original navigation as well as allowing others to reprocess the navigation for their purposes.
