Sample Number 60: SAL:Bottle - salt crystals on outside threads of bottleneck; bottle value looks very slightly high in COMPARE. Analysis methods: ----------------- Salinity samples were collected in glass bottles and analyzed on Guildline Autosal model 8400B, S/N 68572, at IOS. Salinometers are standardized with IAPSO standard seawater. For details on duplicate analysis see file 2011-001_SAL.pdf. Oxygen samples were analyzed 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). All samples were analyzed at sea. A shift in the Oxygen:CTD standardization parameters occurred between events 0032 and 0044; this was not investigated to determine if the resultant change in Thiosulfate normality was real, or the result of a shift in lab temperature. Checks of the fit of Oxygen:CTD against Oxygen:Bottle suggest that the titrated values from the first part of the cruise are lower than those of the latter part by about 0.02 ml/l. For details on duplicate analysis see file 2011-001_OXY.pdf. Nutrient samples were collected in plastic tubes. Most samples were stored frozen and later analysed at IOS. Deep Silicate samples (400 dbar and deeper) were analyzed cool at IOS. An Astoria analyzer was used following methods described in Barwell-Clarke and Whitney (1996). For precision and duplicate analysis see file 2011-001_NUT.pdf. 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 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 and at IOS. When duplicate samples were collected the average of two samples is reported. Variability is assessed as the CV% (std dev / mean*100). For details on duplicates see file 2011-001_CHL.pdf. Phaeopigment data are provided for information only and no quality flags are assigned to them. The minimum detectable level for DMS is 0.10 nM, so “0” values should be interpreted as <0.10. For details on the collection and analysis of the DMS data see file 2011-001_DMS_report.pdf and for duplicates see 2011-001_DMS.pdf. The minimum detectable level for DMSP-D:Bottle is 0.10 nmol/l, so “0” values should be interpreted as <0.10 nmol/l. The minimum detectable level for DMSP-T:Bottle in this file is 0.1 nM from 0 to 20 dbar, and 1 nM from 20 to 200 dbar, so “0” values should be interpreted as < those values. DMSP data are limited to 2 significant figures. For details on analysis see document 2011-001_DMS_report.pdf. HPLC samples were filtered onto 47mm GF/F filters and stored at -80C prior to analysis. Samples were extracted in 95% methanol at -20C for 24 hours and analyzed on a WATERS 2695 HPLC separations system as detailed in Nemcek and Pena, 2014. Analysis was performed ~3 months after collection. The average of two samples is reported. Variability is assessed as the %CV (std dev/mean*100) for duplicate pairs. All pigments below the limit of detection (LOD) are assigned a zero value. TChl-a is the sum of Chl-a, DVchl-a, Chlide-a. References: 1.

For details on how the transmissivity calibration parameters were calculated see the document Transmissivity_Calculation.pdf. The calibration of the Oxygen:Dissolved:CTD channel was done using the method described in the SeaBird Application Note #64-2 (Sea-Bird_64-2_Feb2010.pdf). The Oxygen:Dissolved:CTD channel was corrupted for all or parts of events 0007, 0010, 0015, 0017, 0018, 0019 and 0021. For details on the processing see processing report: 2011-001-proc.pdf NOTE: July 2013: A correction has been applied to Nitrate_plus_Nitrite:Bottle and Phosphate:Bottle data from deep-water cruises analyzed at IOS between 2009 and 2012. For details see the report: Corrections_to_Nitrate_and_Phosphate_Data_2009-2012.pdf $REMARKS Quality flags have the following significance: ---------------------------------------------------------------------------------- 0 = Acceptable measurement with no header comment. 1 = Sample for this measurement was collected but not analyzed. Sample lost. 2 = Acceptable measurement with header comment. 3 = Questionable measurement (probably good). 4 = Poor measurement (probably bad). 5 = Measurement not reported (bad). 6 = Mean of replicate measurements. 7 = Manual chromatographic peak measurement. 8 = Irregular digital chromatographic peak integration. 9 = Sample was planned for this measurement from this bottle but was not collected. ----------------------------------------------------------------------------------- $END !-1-- -2-- -3-- --4--- ---5---- ---6---- ---7---- --8-- --9--- --10- ---11-- ---12--- 13 ---14-- 15 --16- 17 --18-- 19 --20- 21 !Samp Bott Bott Pressu Temperat Salinity Sigma-t: Trans Oxygen Oxyge Fluores Salinity Fl Oxygen: Fl Nitra Fl Phosph Fl Silic Fl !le_ le_ le:F re:CTD ure:CTD :CTD CTD missi :Disso n:Dis cence: :Bottle ag Dissolv ag te_pl ag ate: ag ate: ag !Numb Numb ~ng_ vity: lved: solve CTD: ~o ed: ~o ~Nitr ~o Bottle ~o Bottl ~o !er er Sequ CTD CTD: d:CTD Seapoin tt Bottle: tt ite:B tt tt e tt ! ence Volume :Mass t le Volume le ottle le le le !---- ---- ---- ------ -------- -------- -------- ----- ------ ----- ------- -------- -- ------- -- ----- -- ------ -- ----- -- *END OF HEADER 74 19 19 3.3 8.3781 31.6075 24.5819 53.4 -99.00 -99.0 1.956 31.6101 0 6.843 0 9.7 0 1.03 0 17.5 0 73 18 18 9.7 8.3636 31.6266 24.5990 53.6 -99.00 -99.0 1.954 31.6602 0 6.808 0 9.3 0 1.02 0 16.7 0 72 17 17 24.3 8.6142 31.8863 24.7653 57.5 -99.00 -99.0 1.744 31.8940 0 6.685 6 8.8 0 0.99 0 14.7 0 71 16 16 48.8 8.4774 32.3405 25.1416 61.7 -99.00 -99.0 0.679 32.3429 0 6.596 0 6.5 6 0.87 6 7.9 6 70 15 15 75.5 8.0021 32.8567 25.6165 63.1 -99.00 -99.0 0.160 32.8639 0 5.262 0 15.9 0 1.40 0 18.0 0 69 14 14 100.5 7.8201 33.4787 26.1313 63.7 -99.00 -99.0 0.031 33.4801 0 3.914 0 25.2 0 1.91 0 28.5 0 68 13 13 125.3 7.7233 33.7645 26.3699 63.2 -99.00 -99.0 0.015 33.7638 0 2.662 0 30.4 0 2.29 0 39.4 0 67 12 12 151.4 7.4996 33.8635 26.4797 63.5 -99.00 -99.0 0.016 33.8783 0 2.459 0 32.2 0 2.35 0 42.1 0 66 11 11 174.6 7.1475 33.9188 26.5727 63.7 -99.00 -99.0 0.013 33.9218 0 2.284 0 33.3 6 2.40 6 45.3 6 65 10 10 200.8 6.9404 33.9449 26.6217 63.7 -99.00 -99.0 0.015 33.9477 0 2.086 0 34.2 0 2.48 0 48.9 0 64 9 9 250.4 6.4326 33.9911 26.7258 63.7 -99.00 -99.0 0.015 33.9886 0 1.605 0 37.1 0 2.68 0 57.0 0 63 8 8 300.4 6.1189 34.0102 26.7813 63.8 -99.00 -99.0 0.018 34.0115 0 1.377 0 38.7 0 2.80 0 62.5 0 62 7 7 400.5 5.4152 34.0559 26.9041 64.4 0.90 39.2 0.022 34.0546 0 0.916 0 41.5 0 2.98 0 75.3 0 61 6 6 601.2 4.5630 34.1624 27.0859 64.5 0.40 17.3 0.024 34.1599 0 0.407 0 42.9 0 3.13 0 96.9 0 60 5 5 799.8 4.1170 34.2941 27.2383 64.1 0.22 9.7 0.024 34.2940 4 0.220 0 45.0 0 3.31 0 113.3 0 59 4 4 999.8 3.5736 34.3977 27.3758 64.1 0.26 11.4 0.025 34.3965 0 0.265 0 45.5 6 3.34 6 130.1 6 58 3 3 1251.2 3.0882 34.4641 27.4749 63.7 0.41 18.0 0.024 34.4616 0 0.429 6 45.0 0 3.31 0 143.4 0 57 2 2 1250.3 3.0867 34.4641 27.4751 63.7 0.42 18.1 0.024 34.4637 6 0.423 0 44.2 0 3.26 0 143.5 0 56 1 1 1298.8 2.9880 34.4756 27.4933 63.2 0.46 19.9 0.025 34.4758 0 0.473 3 44.7 0 3.29 0 146.1 0
