    Science objectives/activities planned:
The overall purpose of this expedition is to: 1) examine sea floor processes that control the dissolution of CaCO3 (Jahnke, Sayles, Martin, Hales), determine the particulate and dissolved distributions of 231Pa and 230Th in the water column (Francois) and the surface distributions of carbon isotopes and alkenone biomarkers (Conte). The sampling activities that will be required include: multicorere sampling and deployments of the WHIMP pore water sampling system with the trawl winch; deployments of the HiPPS sediment corer on the hydro wire; deployment/recovery of free vehicle benthic chamber and microelectrode systems; CTD/rosette and deep in situ pumping casts; and underway surface pump sampling.

WHOI shipboard scientific instrumentation desired:
    12 kHz Transducer
Refrigerator
CTD/Rosette System
Pinger for Wire Use
