Cruise description

This cruise went really well on all accounts. It was the first Tully cruise where the rapid COVID-19 tests were used, and everyone tested negative on all three testing. Having the rapid tests done on board was a lot simpler logistically than having the tests done at Saanich Peninsula Hospital and receiving the results a few days later, as prior to the February 2021 cruise. This was also the first Line P cruise to welcome a student back on board the Tully.
Due to the pandemic affecting the schedule on other vessels, we were asked to do some work in Chatham Sound after our Line P work. Thanks to Captain Corfield using two engines when appropriate to give us more speed we managed to do all the planned work.
Trace metal sampling was performed during the Line P portion of the cruise and 46 additional stations were visited in Dixon Entrance, Hecate Strait, and Chatham Sound.
The regular sampling was completed during this cruise using a CTD, a Rosette, the Bongo, the Multiple Plankton Sampler (MPS or Multinet), the Mini bongo and the Go-flo bottles.
