Samples were extracted in 90% acetone for 24 hours at -20C within 10 days of collection and analyzed on a Turner 10AU fluorometer calibrated annually 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). The average of two samples is reported. Variability is assessed as the CV% (std dev / mean*100). For details see worksheet “CV%” in file QF2012-25_CHL-*.xls. Phaeopigment data are provided for information only and no quality flags are assigned to them. Oxygen samples were analyzed at sea using an automated Winkler titration system (Brinkmann Dosimat model 765 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 QF2012-25oxy*.xls. Salinity samples were collected in 200 mL type ll glass bottles with reusable silicone inserts supplied by Xiamen Cuten Accessories Industry Limited and crew 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 1 month after collection. Full details are in file QF2012-25SAL*.xls. Nutrient samples were collected in plastic tubes. One set of samples was collected and and quick frozen in aluminum blocks stored in -20C freezer. These samples were returned to IOS for analysis. Another set of samples from 400m and deeper (to be used for silicate analysis) was collected and stored at 4C in the dark. Theses samples were analyzed at sea during cruise 2012-12 (Line P). All samples were analyzed using the Astoria analyzer following methods described in Barwell-Clarke and Whitney (1996). For precision and duplicate study see file QF2012-25nuts*.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.

For details on how the transmissivity calibration parameters were calculated see the document in folder "\cruise_data\documents\transmissivity". SBE DO calibration was done using the method described in the SeaBird Application NOte #64-2. For further processing details see the processing report 2012-25-proc.doc.
