Cruise description

The daily planning of this cruise was mostly dictated by weather. Many storms interrupted our work along Line P and we had to adjust the order of stations around them. Once we reached station Papa a major storm was coming our way, and we had to go quite far north-east to avoid being stuck in it. Since we had to go more than half-way between station P and Langara Island to avoid the storm, and since some work was planned in Chatham Sound for February 2020, we decided to keep sailing to Dixon Entrance and perform the work planned for next year; it was a better use of ship time than waiting 3 or 4 days for a storm to go by. Before leaving the station P neighbourhood we managed to recover a malfunctioning Glider for Woods Hole Oceanographic Institution. After the Chatham Sound work we still had time to do some stations in the Strait of Georgia. All in all, despite missing six Line P stations, this cruise turned out to be really succesful. More details can be found in the cruise report (Documents section).
The regular sampling was completed during this cruise using a CTD, a Rosette, the Bongo, and the Ring net.
Five Argo drifters and two "cement Sponge-Bob" drifters were deployed for IOS.
