  1. G&G Retreat with the Dean’s Office, Dec. 3, 2007 Cross-Disciplinary Collaborations in G&G Examples What helps facilitate these collaborations

  2. And now also: Ken Rubin Stephanie Ingle Deborah Eason Melissa Rotella Rhea Workman Geochemistry

  3. G-PRIME

  4. Hanohano Anti-Neutrino Detector (PI’s: Learned, Dye, Mahoney) Deploy on central Pacific seafloor to: 1. measure neutrino mixing parameters and resolve neutrino mass hierarchy 2. measure U and Th in deep Earth 3. detect nuclear reactor activity

  5. IODP: Drilling lower crust to reach mantle(Many PIs, incl. E.Hellebrand, K. Johnson & P. Fryer) • Ground-truthing seismic and petrologic models to understand structure of oceanic crust • Fresh mantle peridotites at 800 mbsf? Atlantis Core Complex

  6. Atlantis Core Complex (MAR 30N): olivine-rich gabbroic cumulates instead of mantle No mantle peridotites Seismic reflection cannot necessarily be linked to changes in rock types Progress by collaboration between geophysists, structural geologists, and igneous/metamorphic petrologists

  7. Coastal Geology, Geochronology and Geochemistry: Answering questions about the Age, Environments, Implications of Hawaiian Paleo-Reefs and Shorelines 1. Lana’i - emergent coral clastic terraces - Age progressive, near shore/shoreline facies, not from a megatsunami, lithospheric flexure. (Rubin, Fletcher, Sherman, 2000) 2. Oahu Carbonate Shelf - Pleistocene reef accretion. Located MIS7 reef complex, late MIS5 reef front accretion, relation to shorelines and sea level changes. (Sherman, Fletcher, Rubin, 1999; Fletcher et al., in press; Sherman et al., in prep) Now and in the future: 3. Last Glacial Low stand– Much to learn: Search and discover, date rocks, search some more….. (Fletcher and Rubin)

  8. Mantle Dynamics and Magma GeochemistryIto, Bianco, Becker, Mahoney, Ingle, Sinton, Garcia Combining models of 1) upper mantle flow and 2) melting of a heterogeneous mantle shows that upper mantle dynamics can contribute large geochemical variations that are usually attributed to larger scale processes of mantle mixing and mantle geochemical stratification. Bianco et al., 2007 206Pb/204Pb Ito and Mahoney, 2006

  11. What facilitates cross-disciplinary collaborations? 1. Communication -- Participation in existing seminars -- G&G Distinguished Lecture Series? -- Informal Settings - TGIF -- Stroll the Floors… 2. Students -- RA positions for grad student supported by the department or the school? Pooled R-Funds? 3. Common Objectives -- Often inspired by one or two people. -- As a department, identify some common objectives (place of study or theme).
