Gliders AUV/Dock Profilers Sensors Benthic Nodes Buoys, Power, Telemetry Moorings Linked to shore in near real-time by cyberinfrastructure OOI Elements Mooring Arrays - Pioneer

Endurance Array Multi-platform, multi-scale Fixed and mobile assets Cross-shelf arrays at Newport and Grays Harbor Oregon Line Cabled to RSN 125 km 500 km

OOI is embedded in other systems (NANOOS) NANOOS = Northwest Association of Networked Ocean Observing Systems

Endurance Array: Oregon Full water column Cross- shelf resolution High power, high bandwidth via cable to 80 & 500m Benthic platforms 25m = Inner Shelf waves link to nearshore buoyancy-driven flows 80m = Middle Shelf upwelling jets/fronts sand/mud bottom hypoxia wind stress curl 500m = Slope poleward under- current boundary mixing vertical migration link to RSN

Endurance Array: Washington Full water column Cross-shelf resolution High-power surface buoys Benthic platforms No cable

Science Community Workshop II 17 OOI Data Policy Data will be rapidly disseminated, open, and freely available. Near-real-time with latencies as small as technical feasibility allows. PI sensor data shall be publicly available.*  PI may request exclusive access (up to 1 year)  Case by case basis  Exclusivity expires, all data becomes public

OOI Proposed Installation Schedule

19 Example Research Opportunities Using OOI data Developing models to use OOI data Develop visualization, analysis tools Field experiments near OOI infrastructure Modify/control sampling rates Adding new sensors and/or software

20 simpler vs more complex Refers to the path for evaluation and approval. Simpler – no direct interaction with OOI network hardware or software Complex - direct interaction with OOI network hardware or software (implies direct interaction with OOI operators)

Science Community Workshop II 21 “Simpler” Path (no direct impact to OOI network) 1.Become informed about network, data, access 2.Request funding:  Proposal to appropriate NSF section, or  Proposal to other agency 3.NSF (or other agency) merit review 4.Funded Go to work

Science Community Workshop II 22 “Complex” Path (direct impact) 1.Become informed about network, data, access 2.Submit planning letter to NSF  Receive initial technical assessment and feedback 3.Submit proposal and revised planning letter to NSF:  Proposal to appropriate NSF section  Proposal to other agency (with agency-NSF coordination) 4.NSF (or other agency) merit review, if highly ranked then, 5.More detailed technical assessment 6.Funded Go to work, in collaboration with  OOI Facility Operators Committee (scheduling, engineering, & logistics assistance)  Facility operators provide assistance during research project
