Presentation Transcript

  1. Subduction Factory Studies in the Izu-Bonin-Mariana Arc System: Results and Future Plans

  2. Meeting Objectives to summarize and discuss what we have discovered about how the IBM Subduction Factory operates to advance beyond IBM on the general science goals of the Subduction Factory initiative to explore possible integration of MARGINS-SubFac-IBM science goals with the objectives of the other research programs such as IODP, NOAA “Ocean Exploration”, and studies related to Law of the Sea negotiations. To prepare for the future

  3. We are particularly interested in the extent to which we have addressed the principal science objectives of the Subduction Factory experiment and the extent to which further work is needed: • Subduction parameters as forcing functions on factory output • 2) The volatile cycle through the Subduction Factory • 3) Towards mass balance

  4. Also want to examine 3 other important science objectives Not articulated as such in the original MARGINS science plan, but that are clearly related to MARGINS efforts; two of which are articulated in the IODP Initial Science Plan (ISP): 4) Recycling of Oceanic Lithosphere Into the Deeper Mantle 5) Formation of Continental Crust In addition, we will use the workshop to identify outstanding issues and progress about how subduction zones form.

  5. Other efforts Databases Science Education and Outreach Natural Hazards (these will be discussed more extensively at Thursday evening workshop)

  6. 2.5 days will be spent reviewing research progress Speakers: Please leave time for discussion! Audience: Please discuss issues of significance Both: Please focus on what needs to be known

  7. Donald Rumsfeld can provide philosophical guidance for understanding the Subduction Factory “There are known knowns. These are things we know that we know. There are known unknowns. That is to say, there are things that we know we don't know. But there are also unknown unknowns. There are things we don't know we don't know.” Defense Secretary Donald Rumsfeld, Feb. 12, 2002 news briefing. What are the known knowns? What are the known unknowns? And what are the unknown unknowns?

  8. Last Half Day Discussion What to do next?

  9. Last Half Day Discussion Think Big! What to do next?

  10. A few people to know Convenors: Patty Fryer, Shuichi Kodaira, Jeff Ryan, Bob Stern, Yoshihiko Tatsumi, Doug Wiens MARGINS staff: Cary Kandel IFREE staff: Yoshiko Takeoka

  11. This is the Third IBM meeting 1996 Hayama, Japan 10 US, and 75 Japanese scientists, plus representatives from Australia, Britain, and Germany 2002 Honolulu HI About 100 scientists attended, ~ 60% from the United States, most of the rest from Japan, and some from Europe.

  12. What results do we want to be discussing at the next IBM workshop in 2012? I hope results from IODP/ICDP drilling, ALVIN/SHINKAI/ROV diving, new geophysical and geochemical studies, and GIS/database

  13. Two more things… We’d like to post powerpoint presentations on the web. Presenters:please let Cary Kandel know if this is NOT OK. Do we want to publish a volume of results? If so, we need a couple of editors!

  14. Thanks, and have a great meeting! Questions or Comments?
