Geochemistry
Hanohano Anti-Neutrino Detector (PI’s: Learned, Dye, Mahoney)
Deploy on central Pacific seafloor to:1. measure neutrino mixingparameters and resolve neutrino mass hierarchy2. measure U and Th in deep Earth3. detect nuclear reactor activity
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
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
Atlantis Core Complex (MAR 30N): olivine-rich gabbroic cumulates instead of mantle
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)
Now and in the future:3. Last Glacial Low stand –Much to learn: Search and discover, date rocks, search some more….. (Fletcher and Rubin)
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)
