The purpose of our present study is to define the sea floor morphology and sedimentary environments in an area of Rhode Island Sound using sidescan-sonar imagery, bathymetry data and seismic records. The mosaic, bathymetry, and their interpretations serve many purposes, including: (1) defining the geological variability of the sea floor, which is one of the primary controls of benthic habitat diversity; (2) improving our understanding of the processes that control the distribution and transport of bottom sediments and the distribution of benthic habitats and associated infaunal community structures; and (3) providing a detailed framework for future research, monitoring, and management activities. The sidescan-sonar mosaics and bathymetry images also serve as base maps for subsequent sedimentological, geochemical, and biological observations, because precise information on environmental setting is important for selection of sampling sites and for accurate interpretations of point measures. Purpose: This data layer is a component of the H11321 Survey, Rhode Island Sound, GIS database and represents an interpretation of the sidescan-sonar mosaic and bathymetry imagery for the study area. The interpretation can be used as an overlay for the mosaic image and shows areas of sand waves, bouldery areas, benches, low backscatter, high backscatter, moderate backscatter, and trawl marks.
