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 2423a bout 2 weeks after the cruise. Variability is assessed as the CV% (std dev / mean*100). For details see worksheet “CV%” in file QF2015-21CHL*.xls. Precision Statement: Chlorophyll values ranged from 0.17-9.75 ug/l. Average %CV for this cruise was a very good 3.51% with 2 out of 104 duplicate pairs having a CV>15% and 0 out of 104 duplicate pairs having a CV>50% . Our average dataset %CV is 4 % for 2013 - 2014 so the overall quality of this dataset is very good. Flags and comments apply to chlorophyll values only. No flags or comments are assigned for Phaeopigment values. HPLC samples were filtered onto 47mm GF/F filters and stored at -80C prior to analysis. Samples were extracted in 95% methanol at -20C for 24 hours in the lab and analyzed on a WATERS 2695 HPLC separations system as detailed in Nemcek and Pena, 2014. Analysis was performed ~6 weeks after collection. The average of two samples is reported. Variability is assessed as the %CV (std dev/mean*100) for duplicate pairs. All pigments below the limit of detection (LOD) are assigned a zero value. TChl-a is the sum of Chl-a, DVchl-a, Chlide-a and Me-chlide For further information see file QF2015-021HPLC*.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 QF2015-21OXY*.xls. Salinity samples were collected in 200 mL type ll glass bottles with disposable plastic 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 76 to 82 days after collection. For details including a duplicate analysis, see document QF2015-21SAL*.xls. Nutrient samples were collected in plastic tubes and quick frozen in aluminum blocks stored in -20 freezer. One set of samples was collected and frozen immediately. Another set of samples from 400m and deeper (to be used for silicate analysis) was 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 duplicate analysis, see document QF2015-21nuts*.xls. The ammonium method used at IOS is a simplification of the fluorometric technique of Holmes et al, 1999. This method applies to a wide range of ammonium concentrations, uses the addition of a single working reagent and reduces contamination. Typically, samples are collected during the day and stored in the cold room. The working reagent is added to standards and samples at the same time, and the fluorescence is read approximately 8 hours later using a calibrated TD 700 Fluorometer.
