The paper was improved by a review by Dr. Ursula Röhl. We also acknowledge the ODASES program at Texas A&M University for acquiring the Avaatech XRF scanner for the GCR. Scanning and analysis were paid for by a United States Advisory Committee for Scientific Ocean Drilling (USAC) postcruise grant and by National Science Foundation (NSF) grant OCE-0962184 to M. Lyle.
