All samples were returned to the Institute of Ocean Sciences and analyzed 8 weeks after the cruise on a Turner Trilogy7200-000 fluorometer, using methods described in Holm-Hansen et al. (1965). Fluorescence readings taken before and after sample acidification were used to calculate chlorophyll and phaeopigment concentrations. For further details on methodolgy, see document QF 2022-040_CHL_*.xlsx. NOTE: Flags and comments apply to chlorophyll values only. No flags or comments are assigned for Phaeo-Pigment values Oxygen samples were analyzed at sea using an automated Winkler titration system (Metrohm Dosimat model 876, a UV light source and detector with a 365nm filter controlled by LV02_876 software designed and constructed by Scripps Institution of Oceanography) with modifications based on Carpenter (1965) and adhering to WOCE protocols (Culberson 1991). For details including a precision analysis, see document QF2022-040_OXY*.xlsx. Salinity samples were collected in 200 mL type ll glass bottles with disposable nylon inserts and screw caps supplied by Ocean Scientific International Limited. They were analyzed in a temperature-controlled lab on a Guildline 8400B Salinometer standardized with IAPSO standard seawater 14 - 20 days after collection. For details including a duplicate analysis, see document QF2022-040SAL*.xlsx. Nutrient samples were collected in plastic tubes and quick frozen in aluminum blocks stored in a -20C freezer. For samples 400m and deeper a second set of samples are collected and stored cool for silicate analysis. All samples were returned to the Insitute of Ocean Sciences and they were analyzed using an Astoria-Pacific Analyzer following methods described in IOS Nutrient Methods (1996) Barwell-Clarke and Whitney.

CTD #0550 was used for Event #1 only. CTD #1222 was used for Events 4-91. Conductivity, Transmissivity, Fluorescence and PAR are nominal and unedited except that some records were removed in editing temperature and salinity. Recalibration of dissolved oxygen was based on a comparison with titrated samples for Events 4-91. For Event #1 recalibration was based on the performance of the oxygen sensor during previous cruises. Salinity required no recalibration. Pressure was recalibrated for Event #1. For all other events the pressure offset in the configuration file was adjusted based on results of previous cruises.
