1. A Proposal for a Distributed Earth Observation Data Network Matthew B Jones UC Santa Barbara National Center for Ecological Analysis and Synthesis (NCEAS) Presentation at TDWG 2008 Freemantle, Australia

2. Global Change

3. Critical Areas in the Earth System Where local or regional changes may have strong effects on earth system interactions, feedbacks, or connections

4. Coupled Human & Natural Systems

5. Knowledge Network for Biocomplexity Data Distribution Many existing but unlinked data networks and federations in ecology, hydrology, taxonomy, genetics, vegetation science, oceanography, atmospheric science,...

6. DataNetONE  DataNetONE (Observation Network for Earth)  Michener, Cook, Frame, Hampton, Smith, Allen, Horsburgh, Jones, Sandusky, Scherle, Servilla, Vieglais, Wilson, Allard, Buneman, Butler, Cobb, Cruse, Deelman, DeRoure, Duke, Goble, Hobern, Honeyman, Hutchison, Kelling, Kranowitch, Kunze, Ludaescher, Normore, Pereira, Pouchard, Tenopir, Weltzin, Von Welch  Highly distributed network of earth observational data  Linking existing systems  Focus on long-term sustainability ( 30+ years time horizon)  Technical sustainability  Financial sustainability  Mostly focused on production infrastructure  Continual evaluation and incorporation of research findings

7. DataNetONE Participants

8. Cyberinfrastructure Objectives  Support synthesis in earth observation sciences  Preserve data for long-term studies  Powerful data access to distributed Member Nodes  Support full lifecycle of scientific process  Design goals  Distributed management at Member Nodes  Replication and caching for preservation and performance  Software must provide benefits for scientists today  Evolution of software and standards  Support and adapt existing community software efforts  Emphasize Free and Open Source Software

9. What are the data/sources/providers?  Biological (genome to ecosystem)  Environmental  Atmospheric  Ecological  Hydrological  Oceanographic  Taxonomic  Sources:  Scientists  Research networks  Environmental observatories  Citizen groups

10.  Sources/Providers:  US and international Long Term Ecological Research Programs  Biological specimens associated with museums, herbaria  Observational data relating to invasive species, infectious diseases, wildlife and fisheries, and habitat  Natural resources and conservation data collected by US and international Parks System  Global and continental land cover/land change and biogeochemical data What are the data/sources/providers?

11. Overview of Components  Member Nodes  Earth observing institutions, projects, and networks  Provide resources for their own data and replicated data  Focused on serving their constituencies  Coordinating Nodes  Provide network-wide services to Member Nodes  Geographically replicated services  Investigator Toolkit  Tools for researchers to access DataNetONE  General Purpose and discipline-specific tools  Adapt existing tools where possible

12. Common Service Interface  DataNetONE Service Interface  Federated Identity and Authorization Services  Object Management Services  Discovery and Usage Services  Preservation Services  Network Services

13. DataNetONE Components

14. What is the Investigator Toolkit?  Suite of software tools for researchers  Principal mode of interaction with the network  Design goals  Emphasize Free and Open Source, but support commercial  General analysis frameworks (e.g., R, MATLAB)  Domain-specific tools (e.g., GARP, Phylocom)  Organized using scientific workflows  Communication via the Service Interface

15. Toolkit Functions  Supports the scientific lifecycle  Data management and preservation  Data query and access  Data analysis and visualization  Process management and preservation  Portal software

16. Longevity: organization & community  Broad, active community engagement  Library educators engaging new generations of students  Existing outreach and education  e.g., citizen science portals, NCEAS, NESCent, etc. workshops  Strong organizational sustainability  30 years providing access to ecological data, biodiversity data, etc.  More than 100 years experience for participating libraries
