Cruise description

This cruise went really well. The weather was mostly good and all the planned work got done. Problems with the NOAA mooring PA-011 kept us at Station Papa 24 hours longer than planned so only one acoustic survey line was done over Union Seamount. Still, this work was extra so it's good that we managed to do at least that one line. We also deployed a mooring at Explorer Seamount for a scientist at the Pacific Biological Station.
The regular sampling was completed using a CTD, a Rosette, the Bongo, and the Ring net.
The Trace Metal sampling was performed by using the Go-flo bottles.
Four Argo floats were deployed for IOS and 10 drifters were deployed for NOAA. For further details see 2017-006_cruise_report.pdf in the Documents section.
