Cruise description

This cruise went really well despite the fact that we were three days late leaving the Institute of Ocean Sciences because of problems with the new crane on the CCGS John P Tully's aft-deck. Because of this we had less time to do the mooring work at Station Papa than planned, therefore the work pace was a little crazy; we recovered and re-deployed a sub-surface ADCP mooring one day, and recovered and re-deployed the surface mooring the following two days. Also we had to cancel all the stations on the return leg except for the Hakai Passage/Koeye River stations and the Rivers Inlet stations. As a bonus though we had time to complete two of the stations missed on the previous cruise also due to the aforementioned crane problems.
The sampling done during this cruise was performed using a CTD, a Rosette, a Bongo and a Multiple Plankton Sampler (MPS).
For further details see the Cruise_report.pdf in the Documents section.
