Cruise description

This cruise was 100% successful. All stations were visited and all casts performed.
Special emphasis was given to Trace Metal sampling during this cruise. Two Trace-Metal Rosette (TMR) casts were performed at each major station, as well as some pumping with the Teflon pump. Extra sampling was done at Station Papa with the Go-flo bottles as well as a third TMR cast. The TMR was used again at P16 on the return trip.
In addition to the extensive Trace Metal sampling, extra water was collected for various HPLC experiments. Sensors (two C-star transmissometers) were added to our CTD for the University of Berkeley, California. Their group also collected water for particulate inorganic carbon (PIC) and silicate. Deep organic refractory carbon (DORC) samples were collected for B. Miller at the University of Georgia and dissolved organic carbon (DOC) samples were collected for M. Orellana at the University of Washington (UW).
Finally one Iridium float was deployed at Station Papa for UW/Applied Physics Lab and two weather data drifting buoys were deployed for Environment Canada.
The regular sampling done during this cruise was completed using a CTD, a Rosette, and a Bongo. Two bongo casts were done at each major station - one cast to 250 m and one cast to 1200 m.
