This research used samples and data provided by the Ocean Drilling Program (ODP). ODP is sponsored by the U.S. National Science Foundation and participating countries under the management of the Joint Oceanographic Institutions, Inc. This project was partially funded by the U.S. Science Support Program. This is University of North Carolina, Wilmington, Center for Marine Science Contribution #255.
I am grateful to the Ocean Drilling Program for inviting me to participate on Leg 185, to all members of the Shipboard Scientific Party of Leg 185 for their cooperation on board the ship, and to the ODP personnel and the SEDCO crew who made Leg 185 a success. I also thank Richard Jarrard for insights into the interpretation of shipboard physical properties data and Dr. Sun, at Lamont-Doherty Borehole Research Group, for supplying software for synthetic seismogram calculations. Maps were produced using Generic Mapping Tools software (Wessel and Smith, 1995). Reviews by William Sager and M.F. Moore improved this manuscript.
