LONG-TERM GOALS. Our long-term goal is to provide the fundamental mapping information and visualization tools necessary to support STRATAFORMs multidisciplinary effort to develop a more complete understanding of how short-term oceanographic and geological processes interact to produce the preserved geologic record on the shelf and slope portions of the continental margins. This effort began with detailed mapping of the bathymetry and backscatter of the STRATAFROM survey areas and is now continuing with the integration of the many data sets collected in the northern California STRATAFORM region into a GIS system that will allow all STRATAFORM researchers and others to interactively explore the complex relationships amongst seafloor, water-column, and subsurface parameters in an easy and intuitive fashion. SCIENTIFIC OBJECTIVES. The fundamental objective of the STRATAFORM Swathmapping Program is to provide complete 100 bathymetric and sidescan imagery coverage of the Northern California and N.J. Margin STRATAFORM field areas. This has allowed STRATAFORM investigators to evaluate the geologic processes of the shelf and slope over a continuum of scales. Complete coverage also has provided STRATAFORM investigators with the knowledge that their studies are based on a complete picture of morphological relationships rather than the interpolation of sparsely spaced data. In doing this, we have produced a bathymetric, geomorphological, and potentially lithological framework upon which all subsequent work can be built.
