  1. Breakout Groups and Questions for Discussion Groups: Group 1: CARBON (Chair: Rik Wanninkhof ) Group 2: AIR-SEA EXCHANGE (Chair: Lisan Yu) Group 3: SEA LEVEL AND OCEAN HEAT STORAGE (Co-Chairs: Laury Miller / Syd Levitus) Group 4: OCEAN CIRCULATION (Chair: Molly Baringer) Questions: 1. What are the needs for advancement of the ocean observing system? 2. What are the needs of the ocean observing and user communities? 3. What are the recommended priorities for the Climate Observation Program?

  2. Group 1: CARBON (Chair: Rik Wanninkhof ) • Shawn Smith • Kathy Tedesco • Diane Stanitski • Carbon isn’t heat • Carbon isn’t momentum • Carbon isn’t fresh water • Such that straight analogies with these observing systems isn’t appropriate. • However, data and observing strategies for these parameters is enormously useful to tackle the carbon problem.

  3. . What are the needs for advancement of the ocean observing system? • * A finetuning and updating of the observing strategy • - Updated decorrelation scale analysis will yield better idea of placement of lines and moorings • - Provide an update of mix of platforms (R/V vs. SOP vs. buoys) • recommendation: link CO2 up on R/V with SAMOS • * Linkage to other observing systems • SST, SSS (Science) • XBT/SEAS/TSG lines (Infrastructure and Science) • ARGO/O2 (Science) • Flux reference buoys (Infrastructure and Science)

  4. What are the needs for advancement of the ocean observing system? (cont.) * Investment in autonomous instrumentation (development and deployment) - ARGO/O2 - Submersible/profiling pH - Surface TA, TCO2 - Surface and subsurface pCO2 * Incorporation of a coastal component (need higher spatial and temporal resolution at lower accuracy) - Coastal surveys (“ocean acidification”) - Bouys & platforms (in collaboration w. NSF)

  5. What are the needs for advancement of the ocean observing system? (cont.) *Continued ramping up of observing system to 100 % - CLIVAR/CO2 repeat hydro 30 % increase for 1 line a year ( ten-year campaign is not a snapshot-need profiling floats and sensors on mooring as well). Continued emphasis on ancillary measurements (nutrients, O2, transient tracers) - Increase Ship of opportunity and moored pCO2 by 60 % and lobby on behalf of international partners * Interfacing to modeling -Support climate process team (Princeton, GFDL, MIT,WHOI, NCAR) -OSSIES - Efficient data management,metadata and QC efforts

  6. What are the needs of the ocean observing and user communities? • Four groups: • * Scientific/modeling community • Need data and understanding of data (metadata, data • products [gridded, combined datasets]) • * Decision makers • - Carbon accounting and verification • - Need accurate projections and uncertainty estimates • - Assessments: international to local (IPCC, SOCR) • - Mitigation strategies

  7. What are the needs of the ocean observing and user communities? (cont.) * Economic interests(Carbon currency $6 - $60 ton C) - Need realistic assessments of mitigation and capture (including ecological impacts e.g. deep sea storage, Fe fertilization) - The cost of the business as usual scenario * General public - Need basic information on carbon cycle and C-cycle research

  8. What are the recommended priorities for the Climate Observation Program? • * Remain steadfast and complete the carbon observing system • * Incorporation of coastal carbon efforts (tie-in to continental efforts) • * Focus on the (ecological) response of the ocean to increasing carbon loads [“ocean acidification”] in addition to quantifying the “sink” on seasonal to decadal timescales.

  9. What are the recommended priorities for the Climate Observation Program? (cont) • * Tie-ins to other systems with focus on remote sensing: • operational: • SST (in situ and from space) • Profile (T,S, O2) • Vector winds (in situ and from space) • - research • Salinity • Color • SSH

  10. What are the recommended priorities for the Climate Observation Program? (cont) • * More measurements for same price • -Autonomous instrumentation and platforms • * More bang for the buck from measurements through • modeling • -Data assimilation using carbon proxy data • -Prognostic modeling: • Looking into the future • -Diagnostic modeling: • Which processes are important • What are the feedbacks?
