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 694 24 24 200.3 6.8660 33.9038 26.5994 67.7 2.85 124.0 0.105 693 23 23 200.4 6.8517 33.9039 26.6014 67.8 2.85 124.0 0.102 692 22 22 199.9 6.8593 33.9035 26.6000 67.8 2.85 123.9 0.107 691 21 21 199.9 6.8571 33.9042 26.6009 67.7 2.85 123.9 0.109 690 20 20 600.0 4.3693 34.1650 27.1090 68.3 0.40 17.2 0.114 689 19 19 600.7 4.3694 34.1651 27.1090 68.4 0.40 17.2 0.112 688 18 18 600.4 4.3694 34.1650 27.1089 68.4 0.40 17.2 0.114 687 17 17 600.3 4.3693 34.1651 27.1090 68.4 0.40 17.2 0.114 686 16 16 1000.1 3.4678 34.3936 27.3828 68.3 0.24 10.6 0.120 685 15 15 1000.1 3.4681 34.3933 27.3825 68.3 0.24 10.3 0.118 684 14 14 999.6 3.4675 34.3933 27.3826 68.3 0.24 10.6 0.125 683 13 13 999.9 3.4671 34.3937 27.3830 68.4 0.24 10.6 0.114 682 12 12 1399.6 2.6813 34.5037 27.5431 68.3 0.57 24.8 0.114 681 11 11 1399.7 2.6809 34.5038 27.5433 68.3 0.57 24.6 0.109 680 10 10 1400.3 2.6801 34.5040 27.5435 68.3 0.57 24.9 0.109 679 9 9 1400.3 2.6806 34.5039 27.5434 68.3 0.58 25.0 0.113 678 8 8 1800.1 2.0996 34.5713 27.6460 68.2 1.13 49.0 0.110 677 7 7 1800.1 2.0981 34.5716 27.6464 68.2 1.12 48.6 0.109 676 6 6 1799.8 2.0974 34.5717 27.6465 68.2 1.14 49.3 0.103 675 5 5 1800.1 2.0968 34.5718 27.6466 68.2 1.13 49.2 0.111 674 4 4 2103.5 1.8247 34.6182 27.7052 67.6 1.56 68.0 0.106 673 3 3 2103.2 1.8246 34.6180 27.7050 67.6 1.56 67.9 0.109 672 2 2 2103.4 1.8243 34.6183 27.7053 67.6 1.56 67.9 0.108 671 1 1 2103.9 1.8243 34.6184 27.7054 67.6 1.57 68.0 0.108
