All samples were returned to the Institute of Ocean Sciences and analyzed 10 weeks after the cruise on a Turner Trilogy 7200-000 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 details see worksheet “CV%” in file QF2022-025_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, see document QF2022-025OXY*.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 70 - 79 days after collection. For details, see document QF2022-025SAL*.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 Institute of Ocean Sciences and they were analyzed using an Astoria-Pacific Analyzer following methods described in IOS Nutrient Methods (1996) Barwell-Clarke and Whitney. For details including a duplicate analysis, see document QF2022-025nuts*.xlsx. References: 1. Barwell-Clarke, J. and Whitney, F. 1996. Institute of Ocean Sciences Nutrient Methods and Analysis.

Fluorescence was removed because the values found were extremely low and compared very badly with extracted chlorophyll samples. Channel Oxygen:Dissolved:SBE was recalibrated based on results of cruise 2022-067.
