Samples were extracted in 90% acetone at -20C for 24 hours 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 on board ship or at IOS in room 1310 at IOS ~5 weeks later. The average of two samples is reported. Variability is assessed as the CV% (std dev / mean*100). For details see worksheet “CV%” in file QF2014-21CHL*.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 (Brinkmann Dosimat model 665 for titrations, Dosimat model 865 for dispensing standards and a PC950 Colorimeter controlled by AutoOxy software V3.4) with modifications based on Carpenter (1965) and adhering to WOCE protocols (Culberson 1991). For details including a duplicate analysis, see document QF2014-21OXY*.xls. Salinity samples were collected in 200 mL type ll glass bottles with reusable silicone inserts supplied by Xiamen Cuten Accessories Industry Limited and screw caps supplied by Ocean Scientific International Limited. They were analyzed in a temperature-controlled lab on a Guildline 8400B Salinometer (S/N 68572) standardized with IAPSO standard seawater 3 to 14 days after collection. For details including a duplicate analysis, see document QF2014-21SAL*.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 Barwell-Clarke and Whitney (1996). For details see document QF2014-21nuts*.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.
