Cruise description

This cruise was heavily compromised by time. We barely had enough time to do all the work required, and that did not include any weather days. There are two reasons for this lack of time. Normally the Line P and La Perouse programs share a Coast Guard cycle of the Tully, so we have 28 days to perform both programs. This time, the last day of the cycle was given to Natural Resources Canada (NRCan) so that they could start loading their gear before their allotted ship time. In addition, the Strait of Georgia (SoG) program, normally done over five days on the Vector, was imposed to the Line P and La Perouse programs because the Vector was up in Douglas Channel area for the whole summer. The consequences of having the SoG work at the end of Line P are twofold: not only did we have to give up two full days of operations, we also had to return to the coast going north via Cape Scott, in order to start the SoG stations at the northern end. Normally, we would sail back along Line P coming back from Papa and any work missed on our way west would be done on our way east. This time, each station and cast were a "one chance deal". Because of this some people were overworked due to all the major stations happening every day with no off-day in between and no chance of doing the work on the return leg.
On this cruise we deployed one Argo float for DFO/IOS, three weather data drifting buoys for Environment Canada and two Gliders for WHOI.
The regular sampling done during this cruise was completed using a CTD, a Rosette, a Bongo, and a Multiple Plankton Sampler (MPS). The Trace Metal sampling was performed by using the Trace Metal Rosette (TMR), the Teflon pump, as well as the small boat ("733") for surface sampling.
