  1. Overview: Accomplishments and goals http://www.deep-earth.org/ Barbara Romanowicz Univ. of California, Berkeley CIDER workshop, Marconi Center , May 17, 2009

  2. Motivation and goals • Inter-disciplinary Synthesis Center • Research Incubator • Integrative framework • To tackle the fundamental question of the nature of global dynamic processes that drive plate tectonics on Earth

  3. 40 years after the acceptance of plate tectonics, we are still debating: • -the proportion of heat coming from the core versus radiogenic heating in the mantle; • - The degree of chemical mixing across the mantle; • The origin and even existence of mantle plumes; • the chemical/thermal nature and origin of heterogenity in the deepest mantle; • The nature and importance of coupling between mantle and core; (Albarède and van der Hilst, 1999)

  4. Understandingthe Earth’s interior requires a synthesis of.. Geomagnetism

  5. The traditional approach to geosciences can be compared to… “Blind men and the elephant” Jason Hunt naturalchild.org

  6. Recognizing the need for more effective communication and understanding between the different disciplines, CIDER’s goal is to provide: • An intellectual framework facilitating integrated multi-disciplinary research in the geosciences. • The necessary complement to growing infrastructure for data gathering and distribution. • Across-disciplinary educational environment at all career levels, and in particular to prepare the next generation of earth scientists

  7. CIDER: A”research incubator”: • Working model: KITP ( Kavli Institute for Theoretical Physics, UC Santa Barbara) • Programs on particular themes last 4-6 months • typically start with 1-2 weeks tutorials • Framework for informal interactions • at any given time ~20 participants • each participant commits to stay at least 3 weeks. • Adapt this model to the unique needs of Geosciences • Other models: NESCent; NCEAS

  13. CIDER Products • Presentations at AGU • Papers published as a result of CIDER interactions • Proposals written to CSEDI –some funded ! • Students have gone on to post-doc and faculty positions

  14. CIDER Future Plans • Community Workshop: May 17-20 2009 at Marconi Center (CA) • Expand CIDER activities beyond summer programs? • Consider longer term relationship with KITP versus our own home? • Consolidate/define relationship with Compres, CIG and other infrastructure programs • CIDER proposal to be submitted to NSF/CSEDI in Fall’09 • Summer 2010 program in Santa Barbara (proposal to KITP accepted)

  15. Summer’2010 CIDER Program:“Fluids and volatiles in the Earth’s mantle and core” • June 6- July 18th, 2010 • 2 weeks of tutorial program (June 27-July 11), overlapping with workshop (July 4-July 18). • Theme: “Fluids and volatiles in the Earth’s mantle and core” • Overlaps with KITP program on “The Physics of Glasses” • Followed by 2010 SEDI Meeting (July 19-24, 2010, Santa Barbara).

  16. What role do we want for CIDER beyond what it is now? Think Tank Research Synthesis Center Research Incubator Frontier Center “Master model” for thermo-chemical dynamics of the earth’s interior Intellectually stimulating environment Foster interdisciplinary collaboration Effective mechanisms for cross-disciplinary education Facilitate integrative research

  18. CIDER “without walls” / “ excellence network” activities: • - Summer Programs • - Web resources • Exchange program for post-docs and graduate students • Extended thematic interdisciplinary programs (with KITP?) • Remote courses/seminars • CIDER “in house” activities: • Resident post-docs • Sabbaticals • Short term visitors • Working groups • Catalysis meetings • Facilities: • Seminar /lecture/break out rooms • Offices • Lounge and kitchen • Computer support • Video conferencing • Administrative support

  19. II- Proposed CIDER “without walls” and “excellence network” activities: • -Summer Programs (continued, enhanced) • Web resources (enhanced) • - Exchange program for post-docs and • graduate students • Extended programs (in collaboration / with KITP?) • Distributed graduate seminars

  20. II- Proposed CIDER “in-house” activities • Resident post-doc. program • Resident Sabbaticals (6 months to 1 year) • Short term visitors (2 weeks to 3 months) • Working groups: (10-12 participants collaborating intensively on a topic related to CIDER goals – meet 3-4 times over 2 years, each meeting 3-7 days) • “Catalysis Meetings “ ~30 scientists to work on a major question or research area with a central theme

  21. III- Facilities • Meeting rooms equipped with wireless and ethernet Internet access • Break-out rooms for smaller groups • Lounge and kitchen • Offices to be shared by resident and visiting researchers, equipped with computers • State of the art Video Conferencing • Computing resources (support for visiting researchers) • Administrative support

  22. Governance/Organisation • Management and Staff • Senior Advisory Board (overall goals) • Science Advisory Board (proposals) • Proposal submissions

  23. From 2004 Proposal: • This proposal is for support of the first five years of a new "synthesis institute" called CIDER (Cooperative Institute for Deep Earth Studies), which has no precedent in the area of solid Earth studies. The Institute will undertake a mission of educating a new generation of Earth scientists. It will also provide an environment for studies requiring a concerted effort of leading researchers from different areas of Earth sciences. The purpose is to facilitate the work of individuals, or small groups of researchers, in contrast to a "Big Science" approach. The ultimate goal is to understand the origin, evolution, and dynamics of the Earth and planets.
