  • Description:
    Shallow Water Bathymetry operations are currently performed using launches equipped with high-frequency active sonars. These operations are considered relatively expensive, and contribute to slow survey rates, poor area coverage, and hazardous navigational conditions. Because of these undesirable operating conditions, the National Ocean Survey's System Analysis Division performed this independent objective study reported herein. The overall objective of this study was to identify alternative bathymetric systems, which might replace or complement the Launch-Sonar bathymetric operation. Such systems should allow for easy access to restricted areas, provide more detailed and greater area coverage and, at the same time, be cost effective to operate in waters of three fathoms or less.
