8. Steps Towards a New Driling Program

9. Program Architecture Models 1st Draft Final Draft Science Advisory Structure 1st Draft Final Draft Funding Science Plan INVEST Meeting New Science Plan Draft Internal/External Review Completed Science Plan

10. Science Plan Writing Committee(SPWC) • Community nominations (~100) in October 2009 of potential members following INVEST meeting • SASEC subcommittee working with IODP-MI prepared draft membership • SASEC review and vetting; IWG+ input • IODP-MI consultation with IWG+ (co-chairs) on final list and leadership • Invitations; all accepted by end of November 2009 • Committee formally formed December 2009 • First meeting 1-5 February 2010: Lake Arrowhead, CA

11. SPWC Members • Liaisons: SASEC Chair Maureen Raymo and IODP-MI VP Hans Christian Larsen • Observers: Susan Humphris and Yoshi Tatsumi

12. New Science Plan Considerations from IWG+ to the SPWC • 30-40 pages, including implementation plan • Aimed at broad scientific community to excite many • Mix of exciting basic science and societally relevant science • Should fit with strategic and national priorities of members • Assume 8-12 months JR; 5 months Chikyu, 1 MSP per year • Identify specific high priority riser projects for Chikyu • Include borehole experiments • Highlight linkages to other large programs • Incorporate education and outreach throughout the Plan

13. DRAFT!! DRAFT!! Grand Challenges for the New Drilling Program • Climate Change: Records from the Past; Lessons for the Future • Deep Life: Exploration of the Marine Intraterrestrials • Renewing the Lithosphere: Consequences for our Planet • Earth in Motion on Human Timescales: Plate Boundaries, Fluid Flow and Active Experimentation

14. DRAFT! DRAFT! Climate Change: Records from the Past; Lessons for the Future Urgent Topics • Determining climate sensitivity and potential for extreme polar amplification • Ice sheet stability and rate and magnitude of sea level rise • Ocean acidification Underpinning Topics • Warm climates and extreme events • Climate thresholds: rapid and sudden events • Climate variability on regional scales • Hydrological cycle • ENSO • Ocean circulation states • Monsoon, ITCZ, etc.

15. DRAFT! DRAFT! Deep Life: Exploration of the Marine Intraterrestrials • Extent and Dispersal of Deep Life: Biomes, Connectivity, and Ecology • Limits of Life on Earth: Extremes and Norms of Carbon, Nutrient, Temperature, Pressure, pH, Activity • Evolution and Survival of Life Buried Alive: Adaptation, Enrichment and Repair • Activity and Consequences of Deep Life: Function and Rates of Global Biogeochemical Processes

16. DRAFT! DRAFT! Renewing the Lithosphere: Consequences for our Planet • Creating the Oceanic Lithosphere -- Continental Breakup -- MOR Processes (Mission to the Mantle) -- Hot spots -- LIPS • Solid Earth Regulation of Surficial Environments -- Hydrothermal Elemental Exchange -- Aging of the Lithosphere • Consumption and Reconstruction in Arcs -- Subduction Initiation -- 4D Evolution in Arcs

17. DRAFT! DRAFT! Earth in Motion on Human Timescales: Plate Boundaries, Fluid Flow & Active Experimentation • The Solid Earth in Motion: Earthquakes, Landslides & Their Tsunamis -- Determining the Habitat and Impact of Large and Damaging Earthquakes -- Preconditioning the Subducting Plate -- Submarine Landslides and Their Tsunamis -- Unraveling the Record • Fluids in Motion: Agents of Thermal, Mechanical, Chemical & Biological Change -- Fluid Movement, Chemistry and Mechanical Processes -- Hydrogeology of the Ocean Lithosphere: Processes, Quantification and Links to Subseafloor Life -- A Fresh Look at Gas Hydrates • Establishing a Continued Presence in the Earth: Experimenting with and Listening to the Earth -- Active Perturbation: Revolutionizing the Meaning of “Natural Laboratory” -- Distributed Long-Term Continuous Monitoring -- Opportunities for Cabled Networks

18. Proposed Activities to Foster Community Support Step 1: Develop a 3-person support team to assist in this effort (in negotiation) • Develop 1-pagers on major accomplishments for each theme/discipline • Develop presentation content on Science Plan for new drilling program • Presentations: - universities (can USAC DLS speakers assist?) - professional societies of other fields • Workshop for post-docs and early career scientists • Visits to NSF for briefings • Visits to Congressional staff for briefings • Encourage scientists to talk to Presidents, Deans, etc. • Section on renewal in re-launched IODP Newsletter
