Cruise description

This cruise went really well, both operations-wise and weather-wise. This was the first complete Line P cruise of the 2020 summer, the May 2020 Line P cruise being cancelled due to the COVID-19 pandemic. All the regular Line P work got accomplished. We deployed seven Argo floats for IOS. Trace metal sampling was performed on this cruise. More details can be found in the cruise report (Documents section).
The regular sampling was completed during this cruise using a CTD, a Rosette, the Bongo, the Multiple Plankton Sampler (MPS or Multinet) and the Mini bongo.
The Trace Metal sampling was performed by using the Go-flo bottles.
For further details see 2020-008_cruise_report.pdf in the Documents section.
