Cruise description

This cruise was greatly compromised by the weather. We had to cancel many stations, and lots of important work could not be accomplished. Line P was not completed, no stations were done on Line R and on SS Line, no mooring work was done at Station P, the Glider did not get deployed, and the Bowie Seamount mooring was not recovered. In addition, we had to do a long detour to the north of the Queen Charlotte Islands to avoid yet another storm. At least we did manage to deploy one new mooring at Bowie Seamount.
There were also many problems with the rosette during this cruise. Because of this, all rosette files contain the following warning:
All samples from Bottles Number 13 to 18 should be treated with care. While the CTD data corresponds to the level at which the bottle was fired, in many cases the bottle closed earlier. Notes in the headers of individual files indicate the probable level at which bottles closed, where evidence exists to make that estimate.
See individual files or the rosette CSV files for further details.
The sampling done during this cruise was performed using a CTD, a Rosette, a Bongo and a Ring net.
For further details see the Cruise_report.pdf in the Documents section.
