Cruise description

This cruise went really well. Despite having only two weeks to do the cruise we managed to do everything we were planning to do. It really helped that the crew of the Tully loaded the containers and winches one day before the official start of the cruise, and that we could start loading our gear on Tuesday morning. Also the order in which the loading was done helped a lot. The weather was a touch rough during two short sections of the cruise but for a February weather we sure could not complain. We even managed to do three in-situ pumps casts for UBC, casts which require calm seas. All in all it was an excellent February cruise.
We had a marine bird and mammal observer on board who spotted the first ever recorded Loggerhead Turtle (Caretta caretta) in BC between stations P4 and P5.
On this cruise we deployed three weather data drifting buoys for Environment Canada, and 54 drifters of 4 types (sponge-bob, drogues, Davis, and surface) were deployed for a drifting experiment for IOS.
The regular sampling done during this cruise was completed using a CTD, a Rosette, and a Bongo. The Trace Metal sampling was performed by using the Teflon pump, as well as the Go-flo bottles.
