Salinometers are standardized with IAPSO standard seawater. For details on duplicate analysis see file 2011-026_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. For details on duplicate analysis see file 2011-026_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 2011-026_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 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). Chlorophyll samples were analyzed on board ship in a controlled temperature lab. When duplicate samples were collected the average of two samples is reported. Variability is assessed as the CV% (std dev / mean*100). Phaeopigment data are provided for information only and no quality flags are assigned to them. For details on duplicates see file 2011-026_CHL.pdf. 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 2011-026_DMS_report.pdf and for duplicates see file 2011-026_DMS.pdf. The minimum detectable level for DMSP-D:Bottle is 0.1 nM, so “0” values should be interpreted as <0.1. 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 2011-026_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 ~2 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 and Me-chlide. 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). For details on the processing see processing report: 2011-026-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-- !Samp Bott Bott Pressu Temperat Salinity Sigma-t: Trans Oxygen Oxyge Fluores !le_ le_ le:F re:CTD ure:CTD :CTD CTD missi :Disso n:Dis cence: !Numb Numb ~ng_ vity: lved: solve CTD: !er er Sequ CTD CTD: d:CTD Wetlabs ! ence Volume :Mass !---- ---- ---- ------ -------- -------- -------- ----- ------ ----- ------- *END OF HEADER 553 24 17 45.8 6.9833 32.6971 25.6331 55.6 7.14 310.7 2.222 552 23 16 45.7 6.9775 32.6970 25.6338 55.6 7.15 311.4 2.309 551 22 24 2.5 8.1268 32.6920 25.4691 57.5 6.99 304.5 0.816 550 21 23 10.1 8.1018 32.6922 25.4729 57.3 7.06 307.4 0.886 549 20 22 10.1 8.1019 32.6925 25.4731 57.4 7.06 307.4 0.896 548 19 21 20.5 7.7129 32.6910 25.5279 55.2 7.12 309.8 1.464 547 18 20 20.3 7.7125 32.6909 25.5278 55.4 7.12 309.8 1.599 546 17 19 30.4 7.5467 32.6908 25.5511 54.8 7.13 310.2 1.889 545 16 18 30.4 7.5431 32.6907 25.5515 54.7 7.12 309.9 1.889 544 15 15 49.5 6.5289 32.7123 25.7047 58.0 7.14 310.8 1.695 543 14 14 49.8 6.5202 32.7117 25.7053 58.1 7.14 310.8 1.560 542 13 13 76.0 5.2679 32.7816 25.9124 62.3 7.07 307.4 0.396 541 12 12 75.3 5.2700 32.7810 25.9117 62.2 7.07 307.5 0.391 540 11 11 99.9 5.0057 32.8146 25.9681 63.4 6.93 301.6 0.153 539 10 10 99.8 5.0049 32.8138 25.9675 63.4 6.92 301.2 0.165 538 9 9 149.7 4.3670 33.7300 26.7636 63.6 3.33 144.9 0.062 537 8 8 149.2 4.3691 33.7298 26.7632 63.6 3.33 144.9 0.062 536 7 7 199.9 4.0756 33.8097 26.8573 63.8 2.43 105.5 0.062 535 6 6 199.7 4.0750 33.8101 26.8577 63.8 2.43 105.5 0.054 534 5 5 300.4 4.0177 33.9307 26.9595 63.9 1.59 69.3 0.059 533 4 4 300.7 4.0178 33.9308 26.9596 63.9 1.59 69.2 0.070 532 3 3 401.2 3.9481 34.0394 27.0531 64.1 1.11 48.1 0.053 531 2 2 501.7 3.8177 34.1357 27.1429 64.2 0.86 37.3 0.044 530 1 1 502.1 3.8185 34.1355 27.1426 64.2 0.86 37.5 0.034
