We thank the crew of the JOIDES Resolution for skillful operations in the Woodlark Basin. This research used samples and/or data provided by the Ocean Drilling Program (ODP). ODP is sponsored by the U.S. National Science Foundation (NSF) and participating countries under management of Joint Oceanographic Institutions (JOI), Inc. Funding for this research was provided by a Natural Sciences and Engineering Research Council of Canada grant to R.N.H. and by undergraduate scholarships to M.B. and T.E.C. from the Canadian ODP Secretariat. Funds to cover travel expenses for S.A.A. to participate in Leg 180 were generously provided by the Canadian ODP Secretariat and by the Deans of both Science and Graduate Studies at Memorial University of Newfoundland. R.N.H. thanks the Leg 180 co-chief scientists and the shipboard party for granting all three junior authors (as nonshipboard scientists) access to primary data within the moratorium period. Critical comments by reviewers Carlos Pirmez and Philippe Pezard improved the content and organization of the paper.
