Cruise description

This cruise went really well. The weather was very good in general but because of a day of rougher weather at P20 that station as well as P21 had to be cancelled on our way west and sampled on the way back. The Trace Metal sampling went really well despite one Go-flo bottle and one messenger being broken
The regular sampling was completed using a CTD, a Rosette, the Bongo, the Multiple Plankton Sampler (MPS or Multinet), and the Ring net.
The Trace Metal sampling was performed by using the Go-flo bottles.
Six "Osker" and six "Sponge-Bob"-type drifters were deployed in Juan de Fuca Strait for IOS.
