The installation of the two CORK-II systems during Leg 205 would not have been possible without the expertise of the JOIDES Resolution core technicians "Bubba" J. Attryde and C. Bremner and the entire Transocean drill crew under the supervision of Captain T. Hardy and Offshore Installation Manager "Pepe" J. Estevez. Their dedication and hard work is gratefully acknowledged. We acknowledge the financial support of the National Science Foundation ([NSF] grants OCE 01-18478 for M. Kastner, OCE 01-18422 for H. Jannasch, and OCE 01-18918 for G. Wheat) and the German Science Foundation ([DFG] grant VI 133/4-2 for H. Villinger). The support of the U.S. State Department is greatly appreciated as they worked around the clock to get permission from Costa Rica on very short notice for Alvin dives in their territorial waters. Keir Becker generously shared his Alvin dive time to make inspection of the CORK-II installations possible.
