Data Assimilation System, Oregon Shelf, Summer 2001
Data Assimilation: Model + Data = Optimized Solution (3D+Time)
What types of IT do We Need?Data streams
Management, provenanceKnowledge extractionSeeking patterns and relationships
ComputationScenarios, real-time predictions
CommunicationDiverse users – and two-way communicationsSemantics and ontologiesPresentation and visualizationDistributed and mobile
Climate Change and Public Policy
Regard people as a “keystone species,” not just extracting ecosystem servicesRequire combination of social and ecological systems
Respond to new information and understandingCombination of adaptation and mitigation
Integrated and inclusive approaches to policy formulation and refinement
