Overview: Accomplishments and

goals

CIDER workshop, Marconi Center , May 17, 2009

Barbara RomanowiczUniv. of California,

Berkeley

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

(Albarède and van der Hilst, 1999)

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;

Understanding the Earth’s interior requires a synthesis of..

Geomagnetism

The traditional approach to geosciences can be compared to…

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

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

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

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)

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).

Governance/Organisation

• Management and Staff• Senior Advisory Board (overall

goals)• Science Advisory Board (proposals)• Proposal submissions

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.
