We sincerely thank the U.S. Department of Energy for funding retooling of the PCS and construction of new manifolds. We also thank the captain and crew of the JOIDES Resolution for a successful cruise, C. Paull for use of his degassing tubes, and K. Grigar for drawing Figure F1. Participation on Leg 201 by G.R. Dickens and K.-U. Hinrichs was supported by JOI/USSSP. This research used samples and data provided by the Ocean Drilling Program (ODP). The ODP is sponsored by the U.S. National Science Foundation (NSF) and participating countries under management of Joint Oceanographic Institutions (JOI), Inc.
