    Zhu (Iowa State U): Drainage of wetland prairie in Iowa led to ag land. How does drainage system (intensity & spacing) affect N2O in context of ag systems. Field flux measurements and depth flux measurements => fertilizer pulses N2O flux MUCH (x10+) bigger then freeze/thaw pulse + no drain increases N2O emissions. N2O in subsoil is inverse from surface emissions ? possibly due to microbial community anoxic conditions. Drainage reduces N2O emissions by 8 kg ha-1 yr-1.

    Wednesday, early afternoon posters at
    MR31B-0084 Effects of melt-rock interactions on deformation fabrics and rock physical properties in the shallow mantle lithosphere
    James Kirkpatrick presenting, but this is the the M.Sc. work of Arvid Gonzalez (now core-logging in n. QC). Other authors are myself and Caroline Seyler (U. Minnesota).

    Arvid found that infiltrating mafic melt reduces the preserved strain in mantle olivine.
