Analysis methods: ----------------- Salinity samples were collected opportunistically in very old sailnity bottles that were found onboard the Franklin. The bottles were sealed via phenolic caps with cone inserts and taped with electrical tape and laboratory tape. Despite the bottles fitting on the sample bottle platform on the Autosal, the wide opening meant that it was difficult to get a very good seal between the bung and opening so most samples leaked slightly as the pump pushed air into the head spaces. Samples were analyzed in a temperature-controlled lab on a Guildline 8400B Salinometer standardized with IAPSO standard seawater 29 days after collection.

The PAR sensor was removed after event #17. NOTE: While the SBE fluorescence data are expressed in concentration units, they do not always compare well to extracted chlorophyll samples, particularly for casts far from shore. Salinity sampling was limited in quantity and quality and there was no dissolved oxygen sampling. Recalibration was applied based on previous cruises and one that followed and used the same sensors, as well as post-cruise factory calibrations.
