Abstract:
Long Island Sound is one of the largest estuaries along the Atlantic coast
of the United States. It is a glacially produced, semi-enclosed, northeast-southwest-trending
embayment, which is 150 km long and 30 km across at its widest point. Its
mean water depth is approximately 24 m. The eastern end of the Sound opens
to the Atlantic Ocean through several large passages between islands, whereas
the western end is connected to New York Harbor through a narrow tidal
strait. Long Island Sound abuts the New York-Connecticut metropolitan area
and contains more than 8 million people within its watershed. A study of
the modern sedimentary environments on the sea floor within the Long Island
Sound estuarine system was undertaken as part of a larger research program
by the U.S. Geological Survey (Coastal and Marine Geology Program) conducted
in cooperation with the State of Connecticut Department of Environmental
Protection and the U.S. Environmental Protection Agency. Knowledge of the
bottom sedimentary environments was needed to discern the long-term fate
of wastes and contaminants that have been, or potentially will be, introduced
into the system and to help understand the distribution of benthic biologic
habitats.
Purpose:
This GIS layer represents the researcher's interpretation of the regional
distribution of sea-floor sedimentary environments in Long Island Sound.

Process_Description:
The original interpretation was hand-drawn on mylar based on sidescan-sonar
data, seismic-reflection profiles, and sediment sample data collected in
the study area. The extent of this orginal work only extended shoreward
to the 10m contour interval. This interpretation was then digitized on
a digitizing table. This line information was then transferred to Arc/Info
where significant cleaning of the data was done. These arcs were then converted
to polygons and the attribute information attached. Subsequently, data
from the 10 m contour shoreward was incorporated into the original mylar
interpretive map. These changes were then digitized and incorporated into
the existing Arc/Info coverage. Again, significant cleaning of the arcs
as well as assigning the attribute information was done in Arc/Info. The
original projection of this work was UTM zone 18, NAD27. For this publication,
these data were reprojected into UTM zone 18 NAD 83. This Arc coverage
was exported in the e00 format and imported into ArcView. The new theme
was then saved in the shapefile format.
