We are especially grateful to the Captain, crew and science party of R/V Yokosuka and manned submersible Shinkai 6500, particularly Captain Fusao Saito and operations manager Yoshiji Imai. Constructive reviews by C. Chauvel and O. Ishizuka greatly improved the scope of the paper. This paper also greatly benefitted from detailed discussions with Brian Dreyer and Elizabeth K. Drewes. Samples 37D and 41D were graciously donated by Warren Smith from Scripps Institute of Oceanography (San Diego). I. C. Wright, R. J. Wysoczanski, J. A. Gamble, and M. R. Handler helped the first author in obtaining the samples used for this project and in their XRF analyses. We appreciate the technical assistance of Caroline Harris, Daniel Sampson, Rob Franks, Darren Tollstrup, and Emily Peterman at the UCSC labs. We are also grateful to Christine Laporte-Magoni, Delphine Bosch and Nick Walker for providing Nd, Sr, and Pb isotope measurements for some South Fiji Basin and Havre Trough samples. This work was funded in part by NSF award 0751600 to UCSC.
