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: DC09, Sample Number: 943, Silicate corrected using Bottle salinity. At Station: DC09, Sample Number: 941, Silicate corrected using Bottle salinity. ===================================================================================== Sample_Numbers 924-943: ALL: There was a duplication of sample numbers 24-43 during the cruise, so a leading 9 was added to these samples. Sample_Numbers 924-943: SAL: The salinity bottle labels all had sample numbers that were too high by 1. What should have been called 24 to 43 were labelled 25 to 44. Sample_Number 927: OXY: Particles in flask Sample_Number 933: OXY: Particles in flask Sample_Number 937: OXY-2: Curve rounded at inflection point. Endpoint a bit ambiguous. Sample_Number 939: OXY: Particles in flask Analysis methods: ----------------- Chlorophyll samples were filtered onto 25mm GF/F filters and stored in glass scintillation vials at -80C prior to analysis. 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 (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 1409 with the OSD Water Properties fluoroemter. The average of two samples is reported. Variability is assessed as the CV% (std dev / mean*100). For details see worksheet “CV%” in file QF2013-50CHL*.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 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 QF2013-50OXY*.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 13 to 26 days after collection. For details including a duplicate analysis see file QF2013-50SAL*.xls. Nutrient samples were collected in plastic tubes and quick frozen in aluminum blocks stored in -20 freezer. One set of samples is collected and frozen immediately. Another set of samples from 400m and deeper (to be used for silicate analysis) is collected and stored at 4C in the dark. All samples are returned to IOS for analysis. They were analyzed using an Astoria analyzer following methods described in Barwell-Clarke and Whitney (1996). For raw data, precision and duplicate details see spreadsheet QF2013-50nuts*.xls. References: 1. Barwell-Clarke, J. and Whitney, F. 1996. Institute of Ocean Sciences Nutrient Methods and Analysis.

SBE Fluorescence data from this sensor are considered unreliable. Dark values are much higher than expected from this cruise and other cruises in May and June 2013 and appear to be increasing with time. Fluorescence values have also been lower than usual relative to bottles, particularly at higher chlorophyll values. The data are provided since the shape may be useful. 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. The dissolved oxygen analyst reported that the precision was relatively low (0.012mL/L) even after removal of known bad values and outliers selected by the Chauvenet criterion. Based on the analyst's recommendation, the data are reported with only 2 decimal places in mL/L and no decimal places in umol/kg. For details on the processing see the report: 2013-50-proc.doc. --------------------------------------------------------------------------------- WARNING: SeaPoint Fluorometer #2228 malfunctioned during the latter half of 2013. There were large values at great depth that got steadily higher through the year until it was removed from service. The data have been left in the file so researchers can see the shape of the profile. Comparison with extracted chlorophyll is recommended. *CALIBRATION $TABLE: CORRECTED CHANNELS !
