Analysis methods: ----------------- Chlorophyll samples were filtered onto 25mm GF/F filters and stored in glass scintillation vials at -80C prior to analysis. Samples were extracted in 90% acetone at -20C for 24 hours in the lab and analyzed on a Turner 10AU 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 ~1 weeks after the cruise. The average of two samples is reported. Variability is assessed as the CV% (std dev / mean*100). Flags and comments apply to chlorophyll values only. Precision Statement: Chlorophyll values ranged from 0.24-22.75 ug/l. Average %CV for this cruise was 4.07 with 4 out of 61 duplicate pairs having a CV>10% and 0 out of 61 duplicate pairs having a CV>30%. Our average dataset %CV is 2.84% for 2013 - 2016 so the overall quality of this dataset is good. For details see worksheet “CV%” in file QF2017-23CHL*.xls. 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 QF2017-23OXY*.xls. 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 at IOS on a Guildline 8400B Salinometer (S/N 68572) standardized with IAPSO standard seawater 12 to 21 days after collection. For details including a duplicate analysis see document QF2017-23SAL*.xls. Nutrient samples were collected in plastic tubes and quick frozen in aluminum blocks stored in -20C freezer. One set of samples is collected and frozen immediatedly. Another set of samples from 400m and deeper (to be used for silicate analysis) is collected and stored at 4C in the dark. All samples were returned to IOS for analysis. They were analyzed using an Astoria analyzer following methods described in IOS Nutrient Methods (1996) Barwell-Clarke and Whitney. For details including a precision study, see document NUTS_QF2017-23*.xlsx. References: 1. Barwell-Clarke, J. and Whitney, F. 1996. Institute of Ocean Sciences Nutrient Methods and Analysis.

NOTE: 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. Dissolved oxygen was calibrated using the method described in SeaBird Application Note #64-2, June 2012 revision, except that a small offset in the fit was allowed.
