2-m Bathymetric Grid of National Oceanic and Atmospheric Administration (NOAA) Survey H11446 in Long Island Sound, North of Orient Point, New York (H11446_2M_GEO, Geographic, WGS84)

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: September 16, 2025 | Last Modified: 20211116
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/.
