We also acknowledge the Ocean Drilling and Sustainable Earth Sciences (ODASES) program at Texas A&M University for acquiring the Avaatech XRF scanner for the GCR. Scanning and analysis were paid for by a USAC postcruise grant and by NSF grant OCE-0962184 to ML and AOL. TW was funded by the Deutsche Forschungsgemeinschaft (DFG)-Leibniz Center for Surface Process and Climate Studies at the University of Potsdam. Top of page \| Previous \| Next
