All samples were returned to the Institute of Ocean Sciences after collection. Samples were analyzed 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. Chlorophyll samples were analyzed at IOS in Room 2423, 14 weeks after the cruise. For further details on methodolgy, see document QF CHL 2022-012*.xlsx Methodology sheet. NOTE: Flags and comments apply to chlorophyll values only. No flags or comments are assigned for Phaeo-Pigment values. Oxygen samples were analyzed in the laboratory at the Institute of Ocean Sciences using an automated Winkler titration System (Metrohm Dosimat model 876 and 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 QF2022-012OXY*.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 17 - 30 days after collection. There were only 2 duplicates so no precision assessment was applied. For details, see document QF2022-012SAL*.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. Silicate data corrections where salinity was <25psu were applied by the analyst. For details including a duplicate analysis, see document QF2022-012nuts*.xlsx. References: 1.
