The sample numbers were changed in this file to 9637 and 9638 to avoid confusion. Analysis methods: ----------------- Salinity samples were collected in 200 ml type ll glass bottles with reusable silicone inserts supplied by Xiamen Cuten Accessories Industry Limited and screw caps supplied by Ocean Scientific International Limited. 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 660 24 24 2.1 8.1253 32.4227 25.2580 63.1 6.68 290.7 0.891 659 23 23 1.8 8.1254 32.4227 25.2580 63.1 6.68 290.8 0.989 658 22 22 19.8 8.1264 32.4228 25.2579 63.1 6.68 290.8 1.071 657 21 21 19.6 8.1261 32.4228 25.2580 63.1 6.68 290.9 1.091 656 20 20 40.3 8.1222 32.4222 25.2581 63.3 6.67 290.4 1.083 655 19 19 40.3 8.1224 32.4223 25.2581 63.3 6.67 290.3 1.084 654 18 18 59.7 8.1179 32.4216 25.2582 63.4 6.66 289.8 1.051 653 17 17 59.8 8.1177 32.4216 25.2582 63.5 6.67 290.4 1.033 652 16 16 79.9 8.1011 32.4202 25.2596 63.7 6.64 289.3 1.053 651 15 15 80.2 8.1017 32.4202 25.2595 63.7 6.64 289.3 0.925 650 14 14 99.9 7.3513 32.5621 25.4770 67.0 6.46 281.2 0.281 649 13 13 99.8 7.3666 32.5580 25.4717 67.0 6.49 282.5 0.282 648 12 12 299.8 5.1036 33.8884 26.8079 67.9 2.35 102.1 0.108 647 11 11 300.3 5.1029 33.8884 26.8080 67.9 2.34 101.9 0.107 646 10 10 300.4 5.1011 33.8888 26.8085 67.9 2.34 101.6 0.108 645 9 9 299.9 5.1035 33.8884 26.8079 67.9 2.32 100.9 0.111 644 8 8 600.4 3.9979 34.1469 27.1335 68.5 0.57 24.7 0.113 643 7 7 600.7 3.9982 34.1467 27.1333 68.4 0.57 24.8 0.115 642 6 6 600.3 3.9981 34.1467 27.1333 68.5 0.57 24.7 0.115 641 5 5 600.5 3.9978 34.1469 27.1335 68.5 0.57 24.7 0.119 640 4 4 999.7 3.2736 34.3753 27.3868 68.4 0.25 10.8 0.121 639 3 3 999.9 3.2742 34.3753 27.3867 68.4 0.25 10.7 0.115 9638 2 2 1000.5 3.2708 34.3758 27.3874 68.4 0.25 10.9 0.108 9637 1 1 999.9 3.2708 34.3757 27.3874 68.3 0.25 10.8 0.116
