Sample Number 386: OXY:Bottle - bubble in flask. Sample Number 390: OXY:Bottle - duplicate samples both had bubbles while stirring leading to ambiguous endpoints and poor replication. Samples were not included in the precision analysis due to this problem. Sample Number 393: SAL:Bottle - conductivity ratios were unstable for one duplicate sample despite multiple readings and flushing. Sample Number 394: OXY:Bottle - messy titration curve. Endpoint ambiguous. Sample Number 400: OXY:Bottle - duplicate sample flask was broken prior to sampling. Analysis methods: ----------------- Salinity samples were collected in 200 ml type ll glass bottles with reusable silicone inserts supplied by Xiamen Cuten Accessories Industry Ltd. and screw caps supplied by Ocean Scientific International Limited. They were analyzed in a temperature-controlled lab at IOS on a Guildline 8400B Salinometer (S/N 68572) standardized with IAPSO standard seawater 4 to 19 days after collection. For details on duplicate analysis see file 2014-019_SAL.pdf. Oxygen samples were analyzed at sea using 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 on duplicate analysis see file 2014-019_OXY.pdf. Nutrient samples were collected in plastic tubes. One set of samples was collected and immediately quick frozen in aluminum blocks stored in -20 freezer. Another set of samples from 400 dbar and deeper (to be used for silicate analysis) was collected and stored at 4C in the dark. All samples were returned to IOS for analysis using an Astoria analyzer following methods described in Barwell-Clarke and Whitney (1996). For precision and duplicate analysis see file 2014-019_NUT.pdf. 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 and analyzed on a Turner 10AU fluorometer calibrated 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 during the cruise or at IOS about 7 weeks later. 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 2014-019_CHL.pdf. Flags and comments apply to chlorophyll values only. No flags or comments are assigned for Phaeopigment values. DMS samples were analyzed at sea. The minimum detectable level for DMS is 0.10 nmol/l, so “0” values should be interpreted as <0.10 nmol/l. For details on the collection and analysis of the DMS data see file 2014-019_DMS_report.pdf and for duplicate analysis see 2014-019_DMS.pdf. DMSP-D: 20-75 ml of seawater were allowed to flow directly from the Niskin into a magnetic filtration funnel containing a 0.7 µm GF/F filter. The first 3.5 ml were collected in a polypropylene tube containing 50 µl of a 50% sulphuric acid solution. DMPS-T: 3.5 ml of seawater were collected directly from the Niskin into a polypropylene tube containing 50 µl of a 50% sulphuric acid solution. DMSP-D and DMSP-T: Samples were stored in the dark at 4 degrees C for a minimum of 24 hours. They were hydrolized and analyzed later at the Institute of Ocean Sciences. The minimum detectable level is 0.1 nmol/l, so “0” values should be interpreted as <0.1 nmol/l. For details on analysis see document 2014-019_DMSP.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 ~4-5 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.

Data Processing Notes: ---------------------- Transmissivity, Fluorescence and PAR data are nominal and unedited except that a few bad fluorescence values were replaced with pad values. Post-cruise calibration reports indicate that the primary temperature and conductivity sensors had insignificant drifts. For details on how the transmissivity calibration parameters were calculated see the document Transmissivity_Calculation.pdf. Oxygen:Dissolved:CTD was calibrated using the method described in the Sea-Bird Application Note #64-2 of June 2012 (Sea-Bird_64-2_Jun2012.pdf), except that a small offset in the fit was allowed. For details on the processing see the report: 2014-019-proc.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-- 22 !Samp Bo Bo Pressu Temperat Salinity Sigma-t: Trans Oxygen Oxyge Fluores Salinity Fl Oxygen: Oxyge Fl Nitrat Fl Phospha Fl Silica Fl !le_ tt tt re:CTD ure:CTD :CTD CTD missi :Disso n:Dis cence: :Bottle ag Dissolv n:Dis ag e_plus ag te: ag te: ag !Numb ~u ~u vity: lved: solve CTD: ~o ed: ~ed:B ~o _Nitri ~o Bottle ~o Bottle ~o !er mb en CTD CTD: d:CTD Seapoin tt Bottle: ottle tt te: tt tt tt ! er ce Volume :Mass t le Volume :Mass le Bottle le le le !---- -- -- ------ -------- -------- -------- ----- ------ ----- ------- -------- -- ------- ----- -- ------ -- ------- -- ------ -- *END OF HEADER 408 24 24 5.1 17.5249 32.2926 23.3403 58.5 5.70 248.7 0.521 32.3010 0 5.787 252.5 0 0.00 0 0.386 0 1.64 0 407 23 23 10.2 17.5247 32.2913 23.3394 58.4 5.70 248.8 0.000 -99.0000 0 5.684 248.0 0 0.00 0 0.389 0 1.63 0 406 22 22 24.8 16.2020 32.2972 23.6506 54.4 6.08 265.3 0.848 -99.0000 0 6.044 263.6 0 0.00 0 0.386 0 1.61 0 405 21 21 50.5 9.6732 32.4853 25.0685 62.8 6.41 279.3 4.165 -99.0000 0 6.381 278.0 0 6.12 6 0.850 6 7.29 6 404 20 20 75.6 8.6033 32.5060 25.2524 65.5 6.35 276.4 3.606 -99.0000 0 6.332 275.8 6 10.00 0 1.037 0 11.09 0 403 19 19 100.4 6.9851 32.8886 25.7837 66.5 6.04 262.7 1.957 -99.0000 0 6.009 261.6 0 16.79 0 1.383 0 19.51 0 402 18 18 125.2 6.6653 33.2642 26.1220 66.9 5.60 243.7 2.942 -99.0000 0 5.615 244.4 0 19.38 0 1.491 0 24.24 0 401 17 17 150.7 6.5481 33.6198 26.4178 66.9 4.87 211.6 4.686 -99.0000 0 4.859 211.4 0 23.61 0 1.711 0 32.37 0 400 16 16 175.3 6.0991 33.7562 26.5832 66.8 4.30 187.0 4.419 -99.0000 0 4.286 186.5 2 27.49 0 1.941 0 41.10 0 399 15 15 199.7 5.4686 33.7693 26.6709 66.8 3.87 168.3 4.238 -99.0000 0 3.870 168.4 0 30.20 0 2.150 0 49.17 0 398 14 14 250.8 4.7608 33.8034 26.7792 66.8 2.94 127.9 3.875 -99.0000 0 2.912 126.7 0 35.61 0 2.504 0 63.49 0 397 13 13 300.8 4.3939 33.8347 26.8439 67.0 2.39 103.7 3.715 -99.0000 0 2.375 103.3 6 38.08 0 2.680 0 72.01 0 396 12 12 400.5 4.1957 33.9489 26.9556 67.3 1.37 59.6 3.043 -99.0000 0 1.365 59.4 0 42.05 0 2.938 0 86.16 0 395 11 11 600.8 3.9750 34.1586 27.1452 67.6 0.57 24.9 2.327 -99.0000 0 0.545 23.7 0 44.74 0 3.136 0 107.23 0 394 10 10 800.2 3.4411 34.2686 27.2857 67.5 0.44 19.3 3.080 -99.0000 0 0.346 15.0 3 45.54 0 3.190 0 125.37 0 393 9 9 1000.1 3.0851 34.3580 27.3905 67.6 0.35 15.3 2.216 34.3612 36 0.273 11.9 0 45.93 0 3.234 0 138.50 0 392 8 8 1250.6 2.7099 34.4408 27.4904 67.6 0.33 14.3 1.560 34.4437 0 0.305 13.3 0 46.55 6 3.245 6 151.26 6 391 7 7 1500.8 2.3847 34.5005 27.5660 67.7 0.54 23.5 1.306 34.5039 0 0.549 23.9 0 45.76 0 3.191 0 160.79 0 390 6 6 2001.3 1.9607 34.5838 27.6670 67.7 1.30 56.5 1.736 34.5875 6 1.260 54.8 46 44.25 0 3.040 0 170.59 0 389 5 5 2500.3 1.7415 34.6271 27.7187 67.7 1.91 82.9 2.537 34.6296 0 1.870 81.3 0 42.56 0 2.897 0 173.40 0 388 4 4 3000.5 1.6095 34.6506 27.7474 67.7 2.43 105.5 4.650 34.6521 6 2.397 104.2 0 41.07 0 2.806 0 172.80 0 387 3 3 3501.0 1.5686 34.6638 27.7611 67.4 2.72 118.2 2.593 34.6662 0 2.672 116.1 0 40.13 0 2.741 0 174.07 0 386 2 2 3501.0 1.5686 34.6639 27.7611 67.4 2.72 118.2 2.569 34.6657 0 2.646 115.0 3 40.16 0 2.743 0 174.16 0 385 1 1 3687.8 1.5757 34.6656 27.7620 66.6 2.75 119.5 4.501 -99.0000 0 2.714 118.0 3 40.23 0 2.736 0 175.26 0
