Cruise description

This cruise was quite interesting "weather-wise". Usually in August the seas are calm, there is not much wind and there is a lot of fog. This cruise turned out to be quite windy, with roughly a day of delay because of storms, and the fog horn wasn't heard a single time. Otherwise it was a pretty typical cruise with a bit of gear issues but nothing major. The Line P survey was 100% successful, all casts at all stations were completed. We deployed seven "Arvor" Argo floats and one cement "Sponge-Bob" drifter for IOS. The cesium sampling and trace metal sampling were also performed. 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 and the Multiple Plankton Sampler (MPS or Multinet).
The Trace Metal samples were collected using the Trace Metal Rosette (TMR).
For further details see 2019-008_cruise_report.pdf in the Documents section.
