Temp network code: XF 2012-2013. This project will utilize active- and passive source seismic techniques, using short period and broad band OBSs, respectively, in the Mariana forearc, trench, and outer rise, in order to image the distribution of upper mantle serpentinization. This study will address a central question regarding the importance of serpentinite for understanding subduction zones. The research will quantify the flux of water subducted by upper-mantle serpentinite, and explore the relationships between serpentinization and seismicity in the outer forearc and outer rise.
