Cruise description

During this cruise we were faced with all kinds of problems - science equipment problems, ship problems, and very bad weather. Only 20 of the planned 29 stations were visited, and only 54 of the planned 80 profiles got done.
The drifting sediment traps experiment had to be cancelled because of weather, but at least we got to deploy the University of Washington Iridium float at Station Papa.
The regular sampling done during this cruise was performed using a CTD, a Rosette, some X-Niskins and a Bongo.
