Cruise description

This cruise had to face a few gremlins, the main one being the weather. We sampled stations P3 and P4 on our way west then we went straight to station P20. At P26 we had a very short weather window to do all our sampling but unfortunately we could not recover the Woods Hole Glider, the weather being too rough. After sampling station Papa we had to drift south for about 36 hours while waiting for the weather to improve before finally going to station P19 and resuming our work.
We still managed to do most of the work, except for the CTD cast at station P35 and the deep Bongo at station P20.
We deployed four Argo floats and recovered two coastal gliders for DFO-IOS. We also deployed 18 "Sponge-Bob" type drifters in Haro and Juan de Fuca Straits for DFO-IOS.
Finally, thanks to the extra days allocated for this cruise, we could sample some of the stations for the Strait of Georgia program as well as "giving" one day for the calibration of the Tully acoustic sounders.
No Trace Metal, pH, and DMSPd samples were collected during this cruise.
The regular sampling was completed using a CTD, a Rosette, the Bongo, and the Ring net.
