Undergraduates Matthew McConnell and Angela Duong helped prepare sediments for shore-based analyses. Constructive reviews by C. John and S. Bernasconi greatly improved this data report. Sediment samples and shipboard data were provided by IODP. Funding was provided by Ocean Leadership Consortium/U.S. Science Support Program awards for postexpedition analysis and undergraduate supplemental support. Top of page \| Previous \| Next
