"Water and volatiles in the earth's mantle and core"

*****************************************************************************************

Workshop organizers:

Louise Kellogg, Cin Ty Lee, Jie (Jackie) Li, Michael Manga, Alex Navrotsky and Barbara Romanowicz (lead).

Schedule:

The central focus of the 2010 CIDER Summer Program will be on the geodnamical, geochemical, seismological and minera; physics contraints on the distribution and role of volatiles in the earth.
While the precise themes that will emerge depend on the mix of participants, we anticipate that water will be a central topic of our program. Water plays a crucial role in Earth's weather and climate, it is key to the development and sustainability of life, it shapes the surface of our planet, and it is also thought to facilitate plate tectonics, by reducing the viscosity of minerals and rocks. Water affects the evolution of the earth's lithosphere by profoundly influencing geothermal heat flow and cooling, and contributes to processes that weaken faults, including master faults at plate boundaries. Water geochemically interacts with Earth's silicate crust and mantle in many significant metamorphic reactions, and fundamentally contributes to melting and volcanic processes.The melting of the mantle above subduction zones due to hydration-induced lowering of the melting temperature is the primary mechanism by which mantle differentiates to create continental crust in volcanic arcs. Significant water is carried into the mantle by subduction, in the form of hydrated minerals.

As pressure and temperature increase at upper mantle depths, dehydration processes accompany partial melting and return part of the water to the surface through magmatic and volcanic processes. Although the amounts of water that remain in the rock at greater depths are still unknown, it is likely that the mantle accommodates the water equivalent of several global oceans. More generally, water undoubtedly affects the global rheology and dynamics of the mantle in many ways. For example, it has recently been proposed that the flow of water and its interactions with mantle mineralogical phase transitions near the global 410 km discontinuity produce large regions of concentrated hydration and partial melt at these depths. Understanding the effects of water on current mantle processes and Earth evolution has spawned scientifically rich multidisciplinary on-going observational and theoretical efforts employing seismology, mineralogy, geodynamics, petrology, and rock mechanics.

The quest for understanding the distribution, form and role of volatiles and iron in the solid earth requires a multi-disciplinary effort, at the intersection of mineral physics, seismology, geochemistry and geodynamics. It is a timely and relevant subject for a multi-disciplinary CIDER summer program. It is potentially a very broad topic and could consist of a focus on shallow structure, including fault zones, ground water, gas hydrates, and carbon sequestration, a separate focus on slab dehydration, volcanism, melting, and lithosphere/asthenosphere coupling, as focus on processes in the transition zone and finally a focus on volatiles and iron in the deep mantle and core.

As in 2008, the CIDER program will consist of two main parts:

In the first two weeks, the program is not formally structured. This program provides the opportunity for participants to interact freely and take advantage of the concurrent KITP program on the Physics of Glasses. Alex Navrotsky is in charge of coordination with that program and plans to devote one day (tbd) to discussions of common interests between the two groups.

Weeks 3-5 will feature a tutorial program for about 35 advanced graduate students and post-docs.The goal is to familiarize participants with the tools of geochemistry, geodynamics, mineral physics and seismology that can be used to enravel the properties and dynamics of the Earth's interior. There will be formal lectures by prominent faculty members from different institutions and different fields, and hands on exercises. Although the theme of the 2010 program will serve to guide the content of the lectures and exercises, these will be much broader in scope, designed to cross-educate young researchers in the different disciplines relevant to the earth's interior. During the first week, small interdisciplinary groups will be formed around research topics chosen by the participants, and will engage in the development of a project, the results of which will be presented at the end of the 3 week program.

These activities may continue into week 6. We expect many of the participants will want to attend the SEDI Conference.

Lecturers:
Geochemistry: Cin-Ty Lee (Rice U.), Sujoy Mukhopadhyay (Harvard U.), Bill McDonough (U. Maryland), T. Plank (Lamont)

Geodynamics: Michael Manga (U.C. Berkeley), Thorsten Becker (U.Southern Cal.), Sash Hier-Majumder (U. Maryland), Marc Spiegelman (Columbia/LDEO), Peter Van Keken (U. Michigan)

Mineral Physics: Jie Li (U. Michigan), Marc Hirschmann (U. Minn.), Abby Kavner (UCLA),Wendy Panero (Ohio State), Jan Matas (ENS Lyon)

Seismology: Guy Masters (U.C. San Diego), Barbara Romanowicz (U.C. Berkeley), Alan Levander (Rice U.), Peter Shearer (UC San Diego), Jeroen Tromp (Caltech), Colleen Dalton (Boston University)

These activities may continue into week 6. We expect many of the participants will want to attend the SEDI Conference.

• Researchers at the assistant professor level and higher are welcome to sign up for any part of the program, and we encourage overlap between the first and second part of the program. Travel and on-site expenses will be provided to those that stay for 2 weeks or longer. If you are interested in participating as a lecturer, please contact Barbara Romanowicz at barbara ... seismo.berkeley.edu.


• Graduate students and post-docs signing up for the tutorial part (weeks 3-5) are required to stay for the entire 3 weeks of the tutorial program.


• Participants may bring spouses and we will do our best to accommodate families, and in particular provide childcare. There are many programs for children on and off campus, see information website.


• Number of participants is limited, so early applications are encouraged

Financial Assistance

• Students and post-docs participating in the tutorial program (Weeks 3-5): on-site expenses (on campus housing) will be provided to admitted participants, as well as contribution to travel costs within the US for participants who stay for the whole program.


• Senior participants: on-site expenses and contribution to travel costs within the US will be provided to those who come for at least 2 weeks, for any part of the CIDER program (week 1-6).

Participant Contributions

CIDER participants are asked to contribute to CIDER to help support the costs of exceptional expenses, such as coffee breaks and beach barbecues. The contributions will be as follows:

• Senior participants attending CIDER during the first two weeks (June 12 - June 26) are asked to contribute $10 per week.


• Senior participants attending CIDER during the tutorial (June 27 - July 17) are asked to contribute $20 per week.


• Students and postdocs attending CIDER during the tutorial (June 27 - July 17) are asked to contribute $30 for the three-week program (three weeks of participation are required).
