Cruise description

This cruise went quite well despite being only 14 days and in February. All stations were visited and all casts performed, although some stations had to be done on the return leg.
There were no special rosette casts performed during this cruise, only the regular "Deep" and "DMS" casts for DFO, as well as 3 "UBC" casts - P4, P12 and P26.
Some trace metal sampling was done for DFO using the Go-flo bottles as well as the Teflon pump.
Some 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).
Finally two Iridium floats were deployed at Station Papa for UW/Applied Physics Lab, and two weather data drifting buoys were deployed for Environment Canada, two Carbon Explorer drifters were deployed at Station Papa for the University of Berkeley, and three MetOcean drifters were deployed for DFO/Institute of Ocean Sciences.
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.
For further details see 2013-01_cruise_report.pdf in the Documents section.
