This GIS layer provides the location where samples were taken in a survey conducted by P.L. McCall (1975)

This data layer provides the location where samples were taken in a survey conducted by P. Pellegrino and W. Hubbard (1983)

This GIS layer provides the location where samples were taken in a survey conducted by R.N. Reid, et al (1979)

This GIS layer provides the location where samples were taken in a survey conducted by D. Franz (1976)

This GIS layer provides detailed information from Pellegrino and Hubbard (1983). It shows the sample locations and provides a summary of the total number of species found at each station (species_richness).

This GIS layer provides the location where samples from Pellegrino and Hubbard were summarized to provide detailed analysis of 35 common species found in Long Island Sound benthic communities

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 Plum Island, New York. During November 2009, 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 https://cmgds.marine.usgs.gov/fan_info.php?fa=2009-059-FA.

The storm-induced Coastal Change Hazards component of the National Assessment of Coastal Change Hazards (NACCH) project focuses on understanding the magnitude and variability of extreme storm impacts on sandy beaches. Light detection and ranging (lidar)-derived beach morphologic features such as dune crest, toe and shoreline help define the vulnerability of the beach to storm impacts. This dataset defines the elevation and position of the seaward-most dune crest and toe and the mean high-water shoreline derived from the 2001 Gulf Coast National Oceanic and Atmospheric Administration/U.S. Geological Survey/National Aeronautics and Space Administration (NOAA/USGS/NASA) Airborne Topographic Mapper (ATM) lidar survey. Beach width is included and is defined as the distance between the dune toe and shoreline along a cross-shore profile. The beach slope is calculated using this beach width and the elevation of the shoreline and dune toe.

This GIS layer contains an computer generated model of the distribution of surficial sediments in Long Island Sound.
