What is the OOI?

1. Building collaborations in ocean observing:The view from the OOITim CowlesPrincipal Investigator, Program Director

2. What is the OOI? A system of systems that will document, for 25-30 years, air-sea, water column and seafloor processes, across full ocean depths, using the best technical solutions available. Funded by NSF, managed by Consortium for Ocean Leadership

5. OOI Science Themes • Ocean-Atmosphere Exchange • Climate Variability, Ocean Circulation, and Ecosystems • Turbulent Mixing and Biophysical Interactions • Coastal Ocean Dynamics and Ecosystems • Fluid-Rock Interactions and the Sub-seafloor Biosphere • Plate-scale, Ocean Geodynamics • Overarching Science Foci • Climate change • Carbon cycling • Ocean acidification • Ocean ecosystem health

6. Science Requirements arise from Science Themes • Science Question • Processes to be observed • Spatial Scale • Temporal Scale • Measurements Required • Sensors Required • Sampling Requirements • Site(s) Required for Science • Experiment Description Requirements drive the infrastructure and its capabilities

7. Baseline Design • 4 Global sites • 3 Regional cabled sites in the NE Pacific • 2 Coastal arrays: Mid-Atlantic Pioneer Array, PNW Endurance Array • Each scale incorporates fixed and mobile assets • Cyberinfrastructure: enables adaptive sampling, custom observatory views, collaborative analysis • Interfaces for education users

9. EU - US collaboration in ocean observing • Challenges • We are building infrastructures at different times and at different rates that must have many types of ‘interoperability’

10. EU - US collaboration in ocean observing • Challenges • We are building infrastructures at different times and at different rates that must have many types of ‘interoperability’ • How to share ‘lessons learned’ from planning, initial engineering, etc

11. EU - US collaboration in ocean observing • Challenges • We are building infrastructures at different times and at different rates that must have many types of ‘interoperability’ • How to share ‘lessons learned’ from planning, initial engineering, etc • Lack of visibility/awareness by the creative designers (scientists) of the administrative barriers

12. EU - US collaboration in ocean observing • Challenges • We are building infrastructures at different times and at different rates that must have many types of ‘interoperability’ • How to share ‘lessons learned’ from planning, initial engineering, etc • Lack of visibility/awareness by the creative designers (scientists) of the administrative barriers

13. EU - US collaboration in ocean observing • Overcoming Challenges • Build upon existing relationships among programs • Within IOC • Within WMO • Informal interactions: for example, OOI investigators serve on advisory committees for OceanSITES and EuroSITES, attend meetings of ESONET, EMSO

14. EU - US collaboration in ocean observing • Key opportunities during observing system development • Interoperability across systems • Data protocols - work progressing in several areas • Open access to data - established policy for the OOI • Instrument interfaces (hardware and software) - requires substantial technical specification and collaboration

15. EU - US collaboration in ocean observing • Successes in interoperability lead to • Shared outcomes for collaborative partners • Products of non-recurring engineering • Integration of engineering systems with common standards and protocols • Integration of data systems with common standards and protocols

16. Collaboration Opportunities Successful observatory collaborations will build upon... • Shared or coordinated timetables for planning, approval, and funding • Facilitation of intergovernmental / interagency processes • Open exchange of information - scientists, engineers, agency managers • Explicit opportunities for scientific participation by the ocean sciences community

17. Recommendations • Create opportunities for exchange of technical details of observatories - beyond the current scientist to scientist collaboration • Formalize the outcomes of the informal interactions regarding ‘interoperability’ • Extend the discussions of open access to observatory data

18. Acknowledgements Progress in ocean observing is due to over 20 years of creative thinking by the international community of ocean scientists, and the support of the various funding agencies that have taken risks to enable dreams to be transformed into working infrastructure. Particular thanks to the National Science Foundation for its commitment to the development of the Ocean Observing Initiative

20. Regional Scale • OOI assets off PNW coast are unique • Cable provides high power and bandwidth to • Instrumented nodes on Juan de Fuca plate • full water column moorings at Axial Volcano and Hydrate Ridge • - 2 moorings of Endurance Array connected to the cable

21. Cyberinfrastructure Creates an interactive ocean laboratory integrated by a leading-edge, multi-scalar software tools. open access... fueling science, education, and policy

22. Construction Challenges Transition from planning to building • Must have systems engineering practices in place • Make sure business processes can accommodate 5 to 10-fold increase - contracts, funding, personnel Preparing for the pace of construction • Sufficient numbers of skilled staff • Vetted schedules Planning team may not be the building team
