Value not trusted. -------------------------------------------------------------------------------- This was a joint cruise between the National Research Council of Canada and the Ocean Sciences Division of the Department of Fisheries and oceans, Sidney, B.C. The chief scientist was from NRCC. The OSD contact is Cynthia Wright. -------------------------------------------------------------------------------- Analysis methods: ----------------- Chlorophyll samples were filtered onto 25mm GF/F filters and stored in glass scintillation vials at -20C 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 ~4 weeks after the cruise. The average of two samples is reported. Variability is assessed as the CV% (std dev / mean*100). Precision Statement: Chlorophyll values ranged from 0.49-1.27 ug/l. Average %CV for this cruise was an excellent 2.21% with 0 out of 9 duplicate pairs having a CV>15% and 0 out of 9 duplicate pairs having a CV>50% . Our average dataset %CV is 2.83% for 2013 - 2015 so the overall quality of this dataset is excellent. For details see worksheet “CV%” in file QF2016-02CHL*.xls. Flags and comments apply to chlorophyll values only. No flags or comments are assigned for Phaeopigment values. 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 see document QF2016-02XY*.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 44 to 46 days after collection. For details including a duplicate analysis, see document QF2016-02SAL*.xls. Nutrient samples were collected in plastic tubes and quick frozen in aluminum blocks stored in -20 freezer. All analysis was performed on frozen samples. THey were analyzed using an Astoria analyzer following methods described in IOS Nutrient Methods (1996) Barwell-Clarke and Whitney. For details including a duplicate analysis, see document QF2016-02nuts*.xls. References: 1. Barwell-Clarke, J. and Whitney, F. 1996. Institute of Ocean Sciences Nutrient Methods and Analysis.

For details on how the transmissivity calibration parameters were calculated see the document in folder "\cruise_data\documents\transmissivity". Oxygen:Dissolved:SBE was calibrated using the results of an earlier cruise that used the same DO sensor due to concerns about the quality of dissolved oxygen sampling. The comparison with bottles was too confusing to enable an estimate of the accuracy of the downcast Oxygen:Dissolved:SBE.
