CIDER workshop, Marconi Center , May 17, 2009
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
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)
Understanding the Earth’s interior requires a synthesis of..
Geomagnetism
The traditional approach to geosciences can be compared to…
“Blind men and the elephant”
Jason Hunt naturalchild.org
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).
What role do we want for CIDER beyond what it is now?

thermo-chemical
dynamics of the earth’s

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.
