Results from hydrographic multibeam and side-scan surveys of Long Island Sound

Under a contract with the U.S. National Oceanic and Atmospheric Administration (NOAA), SAIC's Integrated Hydrographic Survey System (IHSS) was used to conduct hydrographic surveys in Long Island Sound, New York, in May, June, July, October and November 1995. The IHSS produced hydrographic data to rigorous International Hydrographic Office (IHO) and NOAA contract standards for both least depth and feature analyses. The authors present an overview of the survey area, survey requirements, and methods (including equipment, survey procedures, and processing). All of these factors interrelate to influence the results of the survey discussed. The results of the survey stand alone as a highly accurate and thorough hydrographic product.
