AB: We have experimented with visualizing the global seafloor data system dbSEABED using the GeoWall visualization technology. dbSEABED is a large, information-rich seafloor database, with over 106 described seafloor sites worldwide. It has been built through combined efforts of universities, agencies, and others. The database focusses on the output of maps, sections and models that visualize the texture, composition and physical properties of the seabed. For some regions there is extensive and detailed sub-bottom information. Since the structure is based on point-site data (maximizes the spatial resolution as component datasets are added), the interpolation of results between the sampled sites is an important issue. We have imported dbSEABED outputs into GeoWall, using a range of applications, with the goals of providing a tool for: (a) inspecting the performance of various mathematical interpolation routines in the process of compiling mappings of US and global seafloor type, and testing their conformance with details of seabed topography; and (b) effective communication of 3D subbottom structure particularly for the sand bodies of the Louisiana shelf, for stratigraphic interpretations and also the planning of sand extraction for the replenishment of barrier systems. The combination of dbSEABED, visualization and the GeoWall brings a powerful combination of data and tools together to closely examine, refine, and analyze large datasets.
