- Abstract:
- The U.S. Geological Survey (USGS), in cooperation with
the National Oceanic and Atmospheric Administration (NOAA), is
producing detailed geologic maps of the coastal sea floor. 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:
- 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.
