The purpose of our present study is to define the sea floor morphology and sedimentary environments in an area of central 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 measurements. Purpose: This text file contains the bathymetry data acquired during National Oceanic and Atmospheric Administration (NOAA) Survey H11321. It includes sounding data collected along track lines as well as small areas of multibeam bathymetry collected in areas of interest, gaps of no data exist between track lines. Data are recorded with 6 columns (coordinates recorded in UTM) in the order: Latitude, Longitude, Depth, Density, Shoal, and Deep. Depth is the value assigned to the grid node based on all the sounding data affecting the node and the weighing scheme. Density is the number of depth measurements affecting the node. Shoal is the shoalest depth measurement affecting the node. Deep is the deepest measurement affecting the node.

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. An Odom Echotrac DF3200 MKII dual-beam echo sounder operating at 24 and 200 kHz acquired the sounding data. In areas of interest, shallow-water multibeam echo-sounder data were acquired with a Reson SeaBat 8125 operating at 455 kHz. 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 where collected, gaps exist between tracklines; vertical datum is mean lower low water, X and Y units are meters, UTM zone 19, NAD83. Data are recorded with 6 columns in the order: Latitude, Longitude, Depth, Density, Shoal, and Deep. Depth is the value assigned to the grid node based on all the sounding data affecting the node and the weighing scheme. Density is the number of depth measurements affecting the node. Shoal is the shoalest depth measurement affecting the node. Deep is the deepest measurement affecting the node.
