Our long-term goal is to understand the processes that create and modify the seabed in the coastal zone and to understand how seabed morphology can be studied using high-resolution swath mapping techniques for bathymetry and backscatter. Swath-mapping techniques have proven extremely valuable to the study of sea-floor morphology on continental shelves, slopes and margins, mid-ocean ridges and in the deep ocean, but systems designed for continental shelf and deeper-water environments are not optimized for the shallow-water of coastal settings. Swath-mapping systems optimum for shallow water have recently become available however, until our system became operational in late 1998 no shallow-water system existed in the U.S. academic community for use in marine research programs. Our objective is to fill this critical gap by obtaining, installing and using a research-grade shallow-water swath bathymetry system that can be moved between vessels as required. This kind of high-resolution morphological data will contribute to ONR programs in the coastal zone such as STRATAFORM and SAX99.
