AB: The Ridge 2000 (R2K) program aims to better understand the complex linkages existing between the biological and physical processes occurring at oceanic spreading centers. R2K scientists are approaching this challenge by studying several key spreading centers, the East Pacific Rise, the Juan de Fuca Ridge, and the Lau Back-arc Basin, from an in-depth and multidisciplinary perspective. However, to characterize and begin interdisciplinary analyses of these deep-sea locations, numerous disparate datasets must be collected. With data types ranging from microbiological fauna to petrogenic core samples to geophysical mantle dynamics, this variation exposes the need for an accessible, integrated, visual database. In conjunction with the principal investigators of applicable experiments, we are taking the first steps towards constructing such a database for the Lau Basin. Building off an earlier visual integration of seafloor bathymetry and multi-channel seismic sections, we intend to incorporate a range of biological, chemical, geological, and geophysical datasets into an interactive, 3-D visual database, or scene. The scene will be constructed by combining individual visual objects derived from various datasets. By assembling the initial scene in this modular fashion, we hope other R2K scientists will ultimately use the database to choose various sub-datasets of interest and create user-specific scenes. Contending with the range in scales associated with these datasets, from meters to hundreds of kilometers, may present a slight challenge, however, once overcome, the integrated data scene should be beneficial to numerous members of the R2K community.
