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-- !Samp Bo Bo Pressu Temperat Salinity Sigma-t: Trans Oxygen Oxyge Fluores !le_ tt tt re:CTD ure:CTD :CTD CTD missi :Disso n:Dis cence: !Numb ~u ~u vity: lved: solve CTD: !er mb en CTD CTD: d:CTD Seapoin ! er ce Volume :Mass t !---- -- -- ------ -------- -------- -------- ----- ------ ----- ------- *END OF HEADER 180 24 24 5.6 15.0020 32.0392 23.7163 46.3 6.24 272.2 1.294 179 23 23 10.3 14.6234 32.0421 23.7990 43.0 6.33 275.9 1.812 178 22 22 25.2 12.4172 32.1616 24.3333 55.5 6.12 266.7 1.644 177 21 21 50.3 9.1470 32.4066 25.0910 65.2 6.18 269.3 0.347 176 20 20 75.3 7.6132 32.6137 25.4812 65.9 5.78 251.6 0.183 175 19 19 100.7 7.1164 32.8730 25.7537 66.0 5.33 231.9 0.111 174 18 18 124.9 7.3570 33.2504 26.0176 66.1 4.32 188.1 0.092 173 17 17 150.1 7.5020 33.5435 26.2278 66.3 3.56 154.8 0.086 172 16 16 175.6 7.5102 33.7739 26.4078 66.4 2.98 129.5 0.083 171 15 15 200.5 7.2953 33.8559 26.5026 66.2 2.61 113.6 0.078 170 14 14 250.3 6.5835 33.9160 26.6467 66.5 2.36 102.7 0.075 169 13 13 300.1 6.2462 33.9670 26.7309 66.3 1.58 68.9 0.073 168 12 12 350.9 5.9133 33.9968 26.7966 66.6 1.35 58.9 0.071 167 11 11 400.9 5.6565 34.0226 26.8487 66.8 1.12 48.6 0.064 166 10 10 451.1 5.1989 34.0281 26.9076 67.3 1.04 45.3 0.062 165 9 9 501.2 4.8588 34.0534 26.9666 67.6 0.85 36.8 0.061 164 8 8 601.1 4.5541 34.1312 27.0621 67.7 0.47 20.5 0.061 163 7 7 699.5 4.2233 34.1884 27.1431 67.6 0.33 14.3 0.061 162 6 6 800.8 3.9630 34.2738 27.2380 67.6 0.22 9.5 0.061 161 5 5 900.8 3.8018 34.3301 27.2992 67.6 0.20 8.8 0.061 160 4 4 1001.1 3.5593 34.3658 27.3517 67.5 0.21 9.2 0.061 159 3 3 1099.6 3.3231 34.4179 27.4161 67.0 0.28 12.2 0.061 158 2 2 1200.5 3.0519 34.4554 27.4713 66.7 0.38 16.6 0.061 157 1 1 1330.0 2.7347 34.4885 27.5263 66.2 0.51 22.0 0.061
