Description:
Abstract:
The U.S. Geological Survey, in cooperation with the National Oceanic and Atmospheric Administration and the Connecticut Department of Environmental Protection, has produced detailed geologic maps of the sea floor in Long Island Sound, a major East Coast estuary surrounded by the most densely populated region of the United States. These studies have built upon cooperative research with the State of Connecticut that was initiated in 1982. The current phase of this research program is directed toward studies of sea-floor sediment distribution, processes that control sediment distribution, nearshore environmental concerns, and the relation of benthic community structures to the sea-floor geology.

Anthropogenic wastes, toxic chemicals, and changes in land-use patterns resulting from residential, commercial, and recreational development have stressed the environment of the Sound, causing degradation and potential loss of benthic habitats (Koppelman and others, 1976; Long Island Sound Study, 1994). Detailed maps of the sea floor are needed to help evaluate the extent of adverse impacts and to help manage resources wisely in the future. Therefore, in a continuing effort to better understand Long Island Sound, we have constructed and interpreted sidescan sonar mosaics (complete-coverage acoustic images of the sea floor) within specific areas of special interest. The mosaic presented herein covers a 190.3 km square area of the sea floor in the West-Central Basin of Long Island Sound.

The mosaics 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, which is a component of the GIS database for NOAA Survey H11045 in the West-Central Basin of Long Island Sound, contains the completed sidescan sonar mosaic for the study area. The image is projected in UTM and has not been enhanced, inverted or cropped. Light tones represent relatively soft returns, lower backscatter, and generally finer sediments. Dark tones represent relatively harder returns, higher backscatter, and generally coarser grained sediments.

Process_Step:
Process_Description:
The sidescan sonar imagery contained in this report was produced from data collected during 2004 as part of NOAA survey H11045 aboard the NOAA Ship RUDE. The data for these surveys were acquired in XTF (extended Triton data format) using a Klein 5500 sidescan sonar towfish set to sweep 100 m to either side of the ship's track. The Klein 5500 tow fish emits two 50°-wide beams tilted down 20° from horizontal, and transmits at 100 kHz. The sidescan sonar were digitally recorded in XTF format using an ISIS data acquisition software package. Once digitally recorded, the XTF data were processed using CARIS SIPS.

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 include 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.
