Cruise description

This cruise got delayed twice. The original dates of 22 February to 13 March were first pushed by a week, the new dates being 1 to 20 March. Our March 1st departure was then delayed again by two more days because of a lack of key personnel aboard the Tully. Fortunately the weather was quite good and we still managed to do most of our planned work. We only had to skip two stations and a bongo along Line P because of weather. Multiple ship problems were encountered during the cruise but the engineering department did an awesome job keeping us afloat and operational during the whole cruise.
Note that no DMS/DMSP samples were collected during this cruise. Trace metal sampling was performed, along with continuous CTD profiling on the return leg from Station Papa using UVic's Moving Vessel Profiler (MVP). See the cruise report for details.
We deployed 4 Argo floats for IOS and 10 drifters for UCSD.
After doing the regular Line P sampling we collected data in Burke and Dean channels, as well as at a few stations in Queen Charlotte Sound and Fitz-Hugh Sound. Weather stations servicing was then performed in the vicinity of Port Hardy just before our return home.
The regular sampling was completed during this cruise using a CTD, a Rosette, the Bongo, and the Go-flo bottles.
For further details see 2022-001_cruise_report.pdf in the Documents section.
