3 OOI CI LCA REVIEW August 2010 OOI-CI – IOOS DMAC Strategy OOI Cyberinfrastructure (CI): a transformational integrated observing infrastructure, providing a link between ocean research and discovery Integrated Ocean Observing System: a federal, regional, and private-sector partnership working to enhance our ability to collect, deliver, and use ocean information IOOS Data Management and Communications (DMAC) Subsystem : a subsystem capable of delivering real-time, delayed-mode, and historical data for in-situ and remotely-sensed physical, chemical and biological observations, as well as, model-generated outputs, including forecasts, to IOOS® users and of delivering all forms of information to and from secure archive facilities. (http://ioos.gov/library/dmac_implementation_2010.pdf) What is our strategy for aligning OOI and IOOS? "OOI is NSF's contribution to IOOS” (then) (now) “One cyberinfrastructure (implementation) shared between two organizations” (now) 3

4 OOI CI LCA REVIEW August 2010 External Observatory Integration Subsystem: Purpose 1. Integrates external observatories (IOOS in R1) with the OOI Integrated Observatory 2. Facilitates inclusion of external data 3. Delivers data in community specific forms 4. Allows immediate full scale testing of the OOI-CI System 5. Introduces OOI to a community of early adopters 4
