Cruise description

This cruise, nicknamed "Tully 1", was the first science cruise on the John P Tully during the 2020 COVID-19 pandemic. Although the main work of 2020-005 was to survey the La Perouse program, many other programs were also executed, in part or in whole. We managed to sample stations P4 to P12 of the Line P program, and only this work will be available here. Since this was not a Line P cruise, there was no Trace Metal and no DMS sampling.
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.
For further details see 2020-005_cruise_report.pdf in the Documents section.
