Cruise description

This cruise went really well. Most instruments worked fine and the weather was really good most of the time. The particularity of this cruise was the work performed in collaboration with the US EXPORTS program. The US NASA-funded EXPORTS program is a large process study ($US 16 million total) that aimed to develop a predictive understanding of the export of photosynthetically-produced organic matter from the surface ocean and its fate in deeper waters (http://oceanexports.org). EXPORTS conducted a two-ship, 28-day experiment near P26 from 13 August to 9 September 2018, ending just prior to the start of the Line P cruise. An NSERC ship time grant, led by Roberta Hamme, facilitated adding two extra days to this cruise to reoccupy the EXPORTS site and perform a small spatial survey in the area. More details can be found in the cruise report (Documents section).
Trace Metal samples were collected using the Trace Metal Rosette (TMR). A wide variety of samples was collected during this cruise (see details in the cruise report).
The regular sampling was completed using a CTD, a Rosette, the Bongo, the Multiple Plankton Sampler (MPS or Multinet), and the Ring net.
Two Argo drifters were deployed at EX-F1 for Dr. Fassbender of MBARI.
For further details see 2018-040_cruise_report.pdf in the Documents section.
