Cruise description

This cruise was somewhat compromised by the weather, but mainly compromised by lack of time. Twelve days of operation at sea would only be enough in perfect weather conditions. We had to cancel many stations, and lots of important work could not be accomplished. Fortunately we were not planning to do any work outside of the regular Line P program work.
The sampling done during this cruise was performed using a CTD, a Rosette, and a Bongo. For further details see the Cruise_report.pdf in the Documents section.
