The purpose of our present study is to interpret the distributions of surficial sediments and sedimentary environments in an area of Narragansett Bay using sidescan sonar imagery, high-resolution bathymetry, and sediment data. The mosaic presented herein covers an area of the sea floor in central Narragansett Bay. The mosaic 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 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 interpretation of point measurements. Purpose: This GIS overlay is a component of the H11310 Survey, Narragansett Bay, GIS database and contains the completed sidescan sonar mosaic for the study area. The image is projected in UTM and has not been enhanced or inverted. Dark tones represent relatively harder returns, higher backscatter, and generally coarser sediments. Light tones represent relatively softer returns, lower backscatter, and generally finer grained sediments.

This image is projected in UTM to maintain the aspect ratio. Process_Step: Process_Description: The sidescan sonar imagery contained in this report was produced from data collected during 2004 as part of NOAA survey H11310 aboard the NOAA Ship RUDE. The data for these surveys were acquired in XTF (extended Triton data format) using a high-resolution Klein 5500. The Klein 5500 tow fish emits five beams on each side of the ship track and transmits at 455 kHz. The sidescan sonar data were digitally recorded in XTF format using an ISIS data acquisition software package. Once digitally recorded, the XTF data were processed using CARIS HIPS/SIPS software. The sidescan sonar data were multiplexed and filtered to convert the data into the desired processing format and to remove speckle noise and corrected for slant-range distortions. The mosaic includes the following standards: 1 meter resolution, image 'shine through', and auto contrast adjustment. The final image was projected in Universal Transverse Mercator to maintain the aspect ratio.
