Adjustment was made for salinity values (when available) of <= 25 psu. Adjustment equation: Silicate:Corrected = Silicate * [1+((-0.003)*(32-S))] where, Silicate:Corrected = corrected silicate concentration in micromoles/litre Silicate = uncorrected silicate concentration in micromoles/litre -0.003 = salt correction factor 32 = salt concentration of artificial seawater used by the WPG Astoria Pacific continuous flow analyser S = salinity of the sample At Station: 3, Sample Number: 120, Silicate corrected using CTD salinity. At Station: 3, Sample Number: 119, Silicate corrected using CTD salinity. ===================================================================================== Sample_Number 119: CHL - variability of reps > 15 % Analysis methods: ----------------- Chlorophyll samples were filtered onto 25mm GF/F filters and stored in glass scintillation vials at -20C prior to analysis. Samples were extracted in 90% acetone at -20C for 24 hours in the lab and analyzed on a Turner 10AU fluorometer which is calibrated annually with commercially pure chlorophyll a (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 in a controlled temperature lab. The average of two samples is reported. Variability is assessed as the CV% (std dev / mean*100). For details see worksheet “CV%” in file QF2012-05_CHL-*.xls. Phaeopigment data are provided for information only and no quality flags are assigned to them. Oxygen samples were analyzed at sea on 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 QF2012-05oxy*.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 within 4 to 12 days of collection. Full details are in file QF2012-05sal*.xls. Nutrient samples were collected in plastic tubes and quick frozen in aluminum blocks stored in a -20C freezer and anlayzed later at the Institute of Ocean Sciences using an Astoria analyzer following methods described in Barwell-Clarke and Whitney (1996). File QF2012-05nuts*.xls includes the raw data and a precision study. 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". Based on the recommendation from SeaBird, the method for calibration of Dissolved Oxygen concentration was changed from that used for 2011 and some 2012 cruises. For more information see the SeaBird Application NOte #64-2, June 2012 revision. It is not expected that this will make a significant difference in the results.
