They were analyzed in a temperature-controlled lab on a Guildline 8400B Salinometer (S/N 68572) standardized with IAPSO standard seawater 33 to 45 days after collection. For details on duplicate analysis see file 2014-001_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 2014-001_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 2014-001_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 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 at IOS. When duplicate samples were collected the average of two samples is reported. Variability is assessed as the CV% (std dev / mean*100). Flags and comments apply to chlorophyll values only. No flags or comments are assigned for Phaeopigment values. For details on duplicates see file 2014-001_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 2014-001_DMS_report.pdf and for duplicates see 2014-001_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 nM, so “0” values should be interpreted as <0.1 nM. Dissolved inorganic carbon (DIC) was determined using coulometric analysis. Total alkalinity (Alk) was determined by potentiometric titration. pH on the total hydrogen ion concentration scale was determined photometrically and is reported at 25C and surface pressure. For duplicates and precision of DIC, ALK and pH samples see files 2014-001_DIC.pdf, 2014-001_ALK.pdf, and 2014-001_pH.pdf respectively. 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 month 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 some records were removed in editing temperature and salinity. 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. The primary Salinity:CTD channel was used for events 0041 and 0043, so it was recalibrated to match the secondary channel which was selected for all other casts. For details on the processing see the report: 2014-001-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 Wetlabs ! er ce Volume :Mass !---- -- -- ------ -------- -------- -------- ----- ------ ----- ------- *END OF HEADER 162 24 24 99.9 8.0453 33.6654 26.2450 65.4 2.98 129.7 0.106 161 23 23 98.6 8.0466 33.6655 26.2449 65.3 3.00 130.3 0.098 160 22 22 97.7 8.0452 33.6654 26.2450 65.3 2.97 129.2 0.108 159 21 21 98.6 8.0445 33.6655 26.2452 65.3 2.96 129.0 0.102 158 20 20 100.8 8.0441 33.6657 26.2454 65.3 2.96 128.9 0.103 157 19 19 102.3 8.0435 33.6695 26.2485 65.3 2.99 129.9 0.109 156 18 18 150.6 7.8399 33.8392 26.4116 65.2 2.47 107.3 0.107 155 17 17 149.4 7.8430 33.8384 26.4105 65.1 2.47 107.4 0.101 154 16 16 148.3 7.8524 33.8365 26.4077 65.1 2.46 106.9 0.094 153 15 15 149.7 7.8458 33.8375 26.4094 65.2 2.47 107.6 0.115 152 14 14 151.0 7.8446 33.8380 26.4100 65.1 2.45 106.7 0.093 151 13 13 151.8 7.8421 33.8383 26.4106 65.4 2.47 107.4 0.102 150 12 12 201.8 7.2469 33.9365 26.5728 66.7 2.20 95.6 0.107 149 11 11 201.6 7.2392 33.9381 26.5751 66.8 2.19 95.2 0.106 148 10 10 204.3 7.2400 33.9371 26.5742 66.8 2.21 95.9 0.106 147 9 9 203.3 7.2333 33.9393 26.5769 67.0 2.21 96.2 0.113 146 8 8 200.3 7.2595 33.9343 26.5693 66.9 2.20 95.8 0.098 145 7 7 199.8 7.2563 33.9351 26.5704 66.8 2.19 95.5 0.108 144 6 6 299.8 6.5339 33.9963 26.7166 66.8 1.61 70.0 0.109 143 5 5 299.4 6.5350 33.9961 26.7163 66.8 1.61 70.0 0.104 142 4 4 298.8 6.5355 33.9962 26.7163 66.8 1.60 69.5 0.109 141 3 3 299.5 6.5394 33.9959 26.7156 66.8 1.60 69.8 0.109 140 2 2 300.5 6.5359 33.9960 26.7161 66.8 1.61 69.9 0.109 139 1 1 300.1 6.5320 33.9966 26.7171 66.8 1.62 70.4 0.109
