Description:
Abstract:
Since 1982, the U.S. Geological Survey, Coastal and Marine Geology Program, has been involved in a collaborative research program with the State of Connecticut to provide long-term studies of Long Island Sound. In support of these studies, several sidescan sonar surveys were conducted within Long Island Sound. The collected sidescan data were processed to produce individual sonar mosaics of various locations within the Long (1) define the geological variability of the sea floor, one of the primary controls of benthic habitat diversity; (2) improve our understanding of the processes that control the distribution and transport of bottom sediments, benthic habitats, and associated infaunal community structures; and (3) provide a detailed framework for future research, monitoring, and management activities. The sidescan mosaics also serve as base maps for subsequent sedimentological, geochemical and biological observations because precise information on environmental setting is important to the selection of sampling sites and to the accurate interpretation of point measurements.
Purpose:
This ArcView shapefile contains the outlined areas of eight sidescan sonar mosaics produced by the U.S. Geological Survey, Coastal and Marine Geology Program, Woods Hole, MA.

Each of the completed Long Island Sound sidescan sonar mosaics were contained in separate PCI database files. These georeferenced files and images were used to trace the extent of the mosaic area.
Process_Step:
Process_Description:
The individual, completed sidescan sonar mosaics were traced with a vector line around the extent of the mosaics. The nodes of the vector line were recorded in geographic coordinates. The vector line was closed to create a complete polygon and saved in a segment of the PCI database with the mosaic image. The saved vector segment was then exported via the PCI utility program as an ArcView shapefile. This step was repeated for all eight LIS region mosaics.
