Jan Cuny U of Oregon Doug Toomey U of Oregon Dawn Wright Oregon State Judy Cushing Evergreen State Developing a Computational Environment for Coupling MOR Data, Maps, and Models: The Virtual Research Vessel (VRV) Prototype
Best studied fast-spreading ridge segment Wealth of data, results, models under-utilized...formats, standards, tools incomplete/incompatible
physical structure of axial magma chambers (seismologists) hydrothermal activity/convection (geologists & geochemists)
Vision for VRV: A Computational Infrastructure MORE than just archiving…. data sharing, tool composition, and model coupling –physical observations (traditional data) –text attributes, video and graphics –programs, models, tools, and scripts for computational processing New data and metadata, format conversion Web interface for distributed computing
Good Fit to NSF ITR Computer science clearly needed – Improvements to current technologies Interdisciplinary, multi-institutional team, history of collaboration EPR yes, but other sites (e.g., Galapagos) and types of environmental data as well Human resource development (undergrads, VRV-ET, Saturday Academy) research plan "compelling" but obviously too ambitious!
Three Components (Solutions) 1 - Data Sharing GIS, RDBMS, computational experiment management system (ViNE) are all needed Non-spatial data and text metadata Computational experimentation More than physical access to files –More than flat files and simple tables
ArcIMS Zoom in Query, simple analyses, add your own data
So far.... Dawn –Our vision & NSF s ITR –The data sharing problem –GIS data visualization Judy –Tool Composition & Model Coupling –Educational outreach –Expected outcomes

Model Coupling Creating a Super Model Steer a single model (Vine), Launch that steering (Vine) across platforms, Transfer data seemlessly across platforms Describe the models « declaratively » –input, parameters, process, output Describe « Process Interactions »

Expected Outcomes Integrating data with metadata, tools and models - A (possibly virtual) database - Tools to visualize data (GIS and MatLab) - Tools for Steering & Coupling - Publish models - Compose tools - Support migration paths for model coupling Apply all to VRV for EPR Educational Outreach -- VRV ET – UOregon, Portland Sat. Academy, Evergreen, etc.
Methods for Model Coupling Express model couplings so they can be implemented as coupling between simulations. Use simulation code analysis and theoretical tools such as Petri Nets to express these couplings. Describe models so that the coupling can be automated and model descriptions can be reused.
