Sample_Number 86: OXY: Dose tip was left outside of sample. Sample lost. Analysis methods: ----------------- Chlorophyll samples were filtered onto 25mm GF/F filters and stored in scintillation vials in the -80C freezer onboard the Vector, then transferred to -80C storage in the lab until analysis. Samples were extracted in 90% acetone at -20C for 24 hours in the lab and analyzed on a Turner Trilogy7200-000 fluorometer calibrated with commercially pure chlorophyll a standard (Sigma). Fluorescence readings taken before and after acidification were used to calculate chlorophyll and phaeopigment concentrations (Holm-Hansen et al 1965). Chlorophyll samples were analyzed at IOS in Room 2423 18 weeks after the cruise. Variability is assessed as the CV% (std dev / mean*100). Flags and comments apply to chlorophyll values only. Chlorophyll values ranged from 0.15 - 57.17 ug/L in 117 samples. 0 samples were below Minimum Limit of Detection (10, and 0 duplicates had a CV%>30. 1 duplicate was rejected (A or B), improving the %CV to 4.64% over 27 duplicate pairs, with 1 samples having a CV%>10 and 0 having a %CV>30. Our average dataset %CV is 3.89 % for 2013 - 2021 using the Turner 10-AU - so the overall quality of this dataset is acceptable For details see worksheet “CV%” in file QF2022-013_CHL*.xlsx. Oxygen samples were analyzed at sea 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 duplicate analysis, see document QF2022-013OXY*.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 21 - 49 days after collection. For details including a duplicate analysis, see document QF2022-013SAL*.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. CTD Salinity values were all > 25psu so no silicate data corrections were needed. For details including a duplicate analysis, see document QF2022-013nuts*.xlsx. References: 1.

Channel pH:SBE was removed for events #67-94 because the sensor malfunctioned. While the CTD fluorescence data are expressed in concentration units, they do not always compare well to extracted chlorophyll samples, particularly for casts far from shore. It is recommended that users check extracted chlorophyll values where available. WARNING: The pH:SBE:Nominal data should be used with caution; no field calibration data were available at the time of processing. Calibration is required for each cast to get absolute values, although general trends within a cast are likely real. For details on the processing see the report: 2022-013_Processing_Report.doc. --------------------------------------------------------------------------------- *CALIBRATION $TABLE: CORRECTED CHANNELS !
