Cruise description

This cruise was a typical February cruise, with strong winds and high sea-states causing cancellation of stations or creating delays during transit time. Despite the weather it was a very successful cruise. Only one Line P station was cancelled: P18. West of Station P24 we sailed across an Eddy, which we took the time to survey (Rosette, Bongo, Trace Metal sampling). After the Line P work was completed we sailed to Dixon Entrance / Chatham Sound for a second consecutive year. We had time to sample all stations on the "top priority" and "second priority" lists for the Chatham Sound area, as well as some of the "lower priority" list of stations. Finally at the beginning of the cruise we deployed a mooring on Swiftsure Bank, and at the very end of the cruise we recovered a Viking buoy near Powell River for DFO. We also deployed a "Sponge-Bob" drifter for IOS at Station Papa. Trace metal sampling was performed on this cruise. More details can be found in the cruise report (Documents section). One thing of note is the problems we had with DMS samples. The GC had some major issues resulting in almost no DMS samples for the entire cruise. More details can be found in the DMS report (Documents section).
The regular sampling was completed during this cruise using a CTD, a Rosette, and the Bongo.
The Trace Metal sampling was performed by using the Go-flo bottles.
For further details see 2020-001_cruise_report.pdf in the Documents section.
