Cruise description

This cruise was 100% successful. All stations were visited and all scheduled casts were done. This was the first time that both the DMS container and the Trace Metal container were set up on the aft-deck, and it worked very well. Most of the Trace Metal sampling was done using the Trace Metal Rosette - TMR - although some sampling was still performed in the chains using a clean pump and the X-Niskin bottles.
During this cruise we also deployed one Argo float for DFO/Institute of Ocean Sciences as well as a weather data drifting buoy 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 - a shallow cast to 250 m and a deeper cast to 1200 m. Four bongo casts were done at P26. For further details see 2011-27_cruise_report.pdf in the Documents section.
