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: 46, Sample Number: 134, Silicate corrected using CTD salinity. ===================================================================================== Comments from secondary file: P:\Cruise_Data_Processing\2011-11\Processing\hydro\2011-11-0039.mrgcln1s ------------------------------------------------------------------------ Comments from secondary file: P:\Cruise_Data_Processing\2011-11\Processing\hydro\2011-11-0039.chl ------------------------------------------------------------------- Sample_Number 131: CHL:variability of reps >15% CV Sample_Number 132: CHL:dup discarded Sample_Number 134: CHL:analytical problems Analysis methods: ----------------- Chlorophyll samples were filtered onto 25mm GF/F filters and stored in glass scintillation vials at -20C at sea and at -80C in the lab. Samples were extracted in 90% acetone for 24 hours in the lab 10-14 days after collection 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). The average of two samples is reported. Variability is assessed as the CV% (std dev / mean*100). For details see worksheet “CV%” in file QF2011-11_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 QF2011-11oxy*.xls. Salinity samples were collected in 200mL type II glass bottles with disposable plastic inserts and screw cap supplied by Ocean Scientific International Ltd. They were analyzed in a temperature-controlled lab on a Guildline 8400B salinometer standardized with IAPSO standard seawater 1 month after collection. Full results including a duplicate analysis , see file QF2011-11sal*.xls. Nutrient samples were collected in plastic tubes and quick frozen in aluminum blocks stored in a -20C freezer. They were later analysed at IOS using an Astoria analyzer was used following methods described in Barwell-Clarke and Whitney (1996).

These averages may contain spikes that would normally be removed in processing. Given the casts are mostly from areas that are not particularly prone to extremely noisy CTD descent rates, and the CTD is believed to have worked well with few spikes, it is likely the errors caused by this problems are are small. The effects on the bottle files are considered less serious than those on the full profile files. Transmissivity, PAR and SBE Fluorescence data are nominal and unedited. 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.
