3-D Visualization of Morphology and Distribution of Acoustic Facies in the STRATAFORM Study Areas.

摘要

Our long-term goal is to provide the fundamental mapping information and visualization tools necessary to support STRATAFORM's 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. 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. Ancillary objectives are to further develop techniques for the remote classification of seafloor materials from swathmapping data and, to develop techniques for the interactive 3D visualization of co-registered surficial and subbottom data.
