Cruise description

This cruise was a success in terms of work planned versus work done at each station. All stations were visited and all casts performed, although a few casts had to be done on the return leg because of bad weather while sailing west. The Trace Metal Rosette (TMR) and Trace Metal winch worked as expected, as did the Hydro winch.
We deployed two weather data drifting buoys for Environment Canada.
The regular sampling done during this cruise was completed using a CTD, a Rosette, a Bongo, as well as the Go-flo bottles and TMR for Trace Metal sampling. Two bongo casts were done at each major station - one cast to 250 m and one cast to 1200 m.
For further details see 2013-18_cruise_report.pdf in the Documents section.
