Description:
Abstract:
This data layer depicts benthic communities found in the New London sidescan
sonar mosaic study area.
Purpose:
This data layer, which focuses on benthic communities, was developed as
part of a cooperative project between the University of New Haven, the
Connecticut DEP, and the U.S. Geological Survey. Benthic communities are
an integral component of the ecology of LIS.
Understanding the role that spatial heterogeneity plays in the dynamic
of benthic landscapes may be a key to developing a better understanding
of the estuarine ecology and the impacts of huuman activity. The purpose
of providing this data layer is to help establish a regional framework
for developing a more extensive GIS for benthic communities in LIS that
can be used for education, research, and environmental management.

Describes mapping and identification of benthic communities in eastern
Long Island Sound
Process_Step:
Process_Description:
Mapping was performed on a sidescan sonar survey conducted by URI. Sediment
samples were collected by grab sampler and were wet sieved to remove the
mud fraction. Coarse fractions were stored in formalin until individual
species specimens could be identified and counted with a binocular microscope
under reflected light.
