Cruise description

This cruise was a success despite some strong winds at the beginning of the cruise. We had to cancel a few casts but we were able to visit these three stations on the return leg.
The mooring work at Station P went really well. The weather was good and all operations went very smoothly. Both the deployment of mooring PA-009 and the recovery of mooring PA-008 were total successes.
The pumping in the chains for Trace Metal went well despite some heavy winds at P4 and a few problems with some kinks in the clean hose.
Most casts that had to be performed at a specific time with respect to the sun position were done at the right time.
While we were offshore an important algal bloom was detected along the coast of North America. We were asked to do a few extra casts upon our return in coastal waters to verify the extent of the bloom in Canadian waters (see "extra" files for data).
On this cruise we deployed 10 weather data drifting buoys for NOAA.
The regular sampling done during this cruise was completed using a CTD, a Rosette, the Bongo, and the Multiple Plankton Sampler (MPS) to collect zooplankton to 3000 dbar at P20 and P26.
The Trace Metal sampling was performed by using the Teflon pump.
For further details see 2015-09_cruise_report.pdf in the Documents section.
