Cruise description

For the first time we went to Station P on the CCGS Sir Wilfrid Laurier. This led to a different cruise in many aspects but we still had a very positive experience. The weather was quite stormy, especially on the way back when we had to wait 2.5 days in 60-knot winds to do P20. The Laurier being a very stable ship the wait was not as bad as it could have been! Because of a rather small lab and a different ship configuration no pH and Trace Metal samples were collected during this cruise.
At the end of the cruise we had time to sample six Strait of Georgia stations.
The regular sampling was completed using a CTD, a Rosette, and the Bongo.
Fifteen "Sponge-Bob"-type drifters were deployed in Haro and Juan de Fuca straits for IOS.
For further details see 2018-001_cruise_report.pdf in the Documents section.
