Presentation Transcript

  1. Ocean Observatories Initiative Ocean Observatories Initiative Cyberinfrastructure • Karen Stocks • OOI CI Data Curator • University of California, San Diego

  2. OOI Science Mission OOI science themes • Ocean-atmosphere exchange • Climate variability, ocean circulation, and ecosystems • Turbulent mixing and biophysical interactions • Fluid-rock interactions and the subseafloor biosphere • Plate-scale, ocean geodynamics Additional science foci • Ocean ecosystem health, climate change, carbon cycling, ocean acidification

  3. OOI Stations

  4. Long-term, in-situ instrumentation

  5. Cyberinfrastructure: linking the marine infrastructure to science and user

  6. Near-Real-Time data Streaming data w/latency of seconds Why Near-Real-Time? • Facilitates rapid modeling and predictions • Enables geophysical event response • Supports disaster response • Enables observatory operations

  7. Near-Real-Time CI • Publication/subscription service • Event/messaging-based system • Dynamic user interface • Automated quality control

  8. Time Series Data OOI has defined set of core data products it will produce over the 25-year timeframe of OOI. These must be scientifically-meaningful time-series data able to support, for example, climate change research.

  9. Long term data products Time series will span • deployments • redeployments • calibrations • recalibrations • instrument swaps • model changes • algorithm changes • platform changes…

  10. Long term data products Time series will span • deployments • redeployments • calibrations • recalibrations • instrument swaps • model changes • algorithm changes • platform changes… = Event-driven system; data & metadata models, and user interface designed for dynamic data

  11. OOI Integrated Observatory Observatory Requirements:Provide one integrated observatory interface to investigate observations, manage the observatory and its assets and collaborate with each other in teams.

  12. CI Release-1: Data Distribution Network Provide framework for discovery and interaction based on data-intensive users’ needs CI Release-2: Managed Instrument Network Provide support for operations and maintenance of marine networks based on RSN and CGSN needs CI Release-3: On Demand Measurement Processing Provide dynamic analysis and visualization tools based on science communities’ user needs CI Release-4: Interactive Ocean Observatory Provide mission control and collaboration support based on science communities’ needs Scientific Collaboration General Science Users ScienceExperts Resource Providers Spiral Development Plan

  13. Release 2 – Late 2012Target: Instrument Operation Fully managed instrument activation and control; ready for deployment on OOI moorings and cable infrastructure • Operate Marine Observatories • Operate Platforms and Instruments • Manage Instrument Lifecycle • Test and Troubleshoot Instruments • Acquire Data and Generate Data Products • Search Data • Visualize Data • Manage the Integrated Observatory Network

  14. Release 2 Target: Core data production

  15. Release 3 – Late 2013 • First broad public release supporting scientists, education, and the public. • The “externalization” of OOI CI will be fully developed in R3 • data formats, services, and standards for interoperability with external communities and applications

  16. Release 3 – Late 2013 • First broad public release supporting scientists, education, and the public. • The “externalization” of OOI CI will be fully developed in R3 • data formats, services, and standards for interoperability with external communities and applications

  17. National Data Center Submission • OOI falls under NSF data policy • Will submit (offer) all data to the appropriate National Data Center, as soon as possible after aquisition • Let’s talk…

  18. NetCDF CF NetCDF Attribute Convention for Dataset Discovery ISO 19115 Geographic Metadata OGC GML Application Schema – Coverages/ISO 19124 Schema for Coverage Geometry and Function CF-NetCDF Encoding (a profile of DAP) THREDDS & DAP Determined technologies/standards

  19. Create interoperability with select target communities. The initial target community is NOAA IOOS (data and metadata model mappings) NEPTUNE Canada and the World Meteorological Organization later Present the OOI-CI using the same interface as the existing IOOS Regional Associations (RA’s) Enable acquisition of science data from external observatories (DAP, SOS, HFR, Glider, MetOcean Models) Distribution of OOI-CI data via the services/protocols used by the IOOS RA’s (DAP, SOS) External Observatory Integration (Release 3)

  20. Summary • CI supports instrument operation and data management as well as data access • Designed to support • Near-real-time data and access • Long-term time series • Iterative releases: late 2012 instrument management; late 2013 broad public release • Will interporate with other observatories, contribute to National Data Centers, and support community standards, services, and formats
