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 ~3 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 0.56-11.61 ug/l. The dataset had an average %CV of 3.75%, 0 out of 9 duplicate pairs having a CV>15% and 0 out of 31 duplicate pairs having a CV>50% . Our average dataset %CV is 2.83% for 2013 - 2015 so the overall quality of this dataset is within 1 standard deviation (4.79%) and therefore very good. For details see worksheet “CV%” in file QF2016-03CHL*.xls. Flags and comments apply to chlorophyll values only. No flags or comments are assigned for Phaeopigment values. 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 31 to 36 days after collection. For details including a duplicate analysis, see document QF2016-03SAL*.xls. Nutrient samples were collected in plastic tubes and quick frozen in aluminum blocks stored in -20C 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 Nuts_QF2016-03nuts*.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". Salinity calibration sampling suggests that calibration drift is small, but the evidence is limited. There was no dissolved oxygen calibration sampling. Recalibration was based on an earlier cruise.
