Cruise description

This cruise was very successful.  Even though the weather was somewhat bumpy at times, we managed to visit all the stations, some of them twice, by going straight to Station P from station P20 and working on the way back.  This was the first cruise where the new Mid-ship rosette station was officially used.  Two Haida eddies were situated along Line P while we were there: one centered on station P8 and the other slightly north of station P14.  The sampling done during this cruise was performed using a CTD, a Rosette, a Bongo and a Live Reeve net.
