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 within 5 weeks of 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 0.69-24.87 ug/l. Average %CV for this cruise was 7.75% with 2 out of 14 duplicate pairs having a CV>15% and 0 out of 14 duplicate pairs having a CV>50%. Our average dataset %CV is 2.83 % for 2013 - 2015. This dataset was within 1 standard deviation of this 3 year average. For details see worksheet “CV%” in file QF2016-20CHL*.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 within 105 to 111 days after collection. There were no duplicates taken, so there is no precision analysis. For details see document QF2016-20SAL*.xls. Nutrient samples were collected in plastic tubes and quick frozen in aluminum blocks stored in a -20C freezer. All analysis was performed on frozen samples. 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 QF2016-20nuts*.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". There was no salinity calibration sampling, but evidence from previous cruises suggests errors are <0.002psu. There was no dissolved oxygen calibration sampling. Recalibration was based on an earlier cruise. No estimate can be made for the accuracy of the Oxygen:Dissolved:SBE channel. Channel Oxygen:Dissolved:SBE was removed from events #8, 10 and 12 due to sensor malfunction. For details on the processing see the report: 2016-20_Processing_Report.doc. --------------------------------------------------------------------------------- *CALIBRATION $TABLE: CORRECTED CHANNELS !
