Abstract

The surficial geology of a 6-km X 8-km section of the western part of Long Island Sound has been mapped. The map area is 4 to 12 km south of the mouth of the Housatonic River in 14 to 40 m water depth (see location map). This study is part of an interdisciplinary program to define the surficial geology and benthic habitats in Long Island Sound and to see how they are changing with time, and includes, in addition to this map area, the other survey areas shown on the location map. The U.S. Geological Survey, in cooperation with the University of New Haven and the Connecticut Geological and Natural History Survey, completed a bathymetric, sidescan sonar, and high-resolution seismic-reflection survey of the study area during November 1993 as the first phase of this long-term program. The second phase, which involved bottom sampling and photography, was completed during April-August 1995. Presented in this report is the surficial geological information including the bathymetry, a sidescan sonar mosaic, a preliminary interpretation of the mosaic, and a sediment distribution map of the study area.
