We would like to acknowledge the Captain and crew of the JOIDES Resolution and the ODP technical staff for a very successful cruise. The able laboratory assistance of chemistry wizards Tim Bronk and Anne Pimmel was particularly helpful. Their dedication contributed greatly to the success of the shipboard inorganic geochemistry program. Technical assistance was provided at the SOEST atomic spectroscopy facilities by Charles M. Fraley and Ron Pflaum. FIA analyses were carried out by Cecily Chun and Toshiko Sato. Thoughtful critical reviews by H. J. Brumsack and R. W. Murray helped to considerably improve this paper. This research was funded in part by a postcruise research grant from JOI/USSP to EDC. This is SOEST contribution 5027.
