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, multibeam bathymetry, 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 measurements. Purpose: This text file contains the multibeam bathymetry data acquired during National Oceanic and Atmospheric Administration (NOAA) Survey H11320. Data are recorded in XYZ triples with coordinates recorded in UTM.

Process_Step: Process_Description: The multibeam data for this survey were acquired in XTF (extended Triton data format) and recorded digitally through an ISIS data acquisition system. Once digitally recorded, the XTF data were processed using CARIS HIPS/SIPS software to quality control the data and to incorporate sound velocity and tidal corrections. Data were gridded to 1m; vertical datum is mean lower low water.
