They were analyzed in a temperature-controlled lab on a Guildline 8400B Salinometer (S/N 68572) standardized with IAPSO standard seawater within 2 to 21 days after collection. For details on duplicate analysis see file 2013-001_SAL.pdf. Oxygen samples were analyzed at sea on 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 2013-001_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 IOS Nutrient Methods (1996) Barwell-Clarke and Whitney. For precision and duplicate analysis see file 2013-001_NUT.pdf. Chlorophyll samples were filtered onto 25mm GF/F filters and stored in glass scintillation vials at -20C prior to analysis. Samples were extracted in 90% acetone at -20C for 24 hours and analyzed on a Turner 10AU fluorometer which is calibrated annually with commercially pure chlorophyll a (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 in a controlled temperature lab. 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 2013-001_CHL.pdf. Phaeopigment data are provided for information only and no quality flags are assigned to them. 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 2013-001_DMS_report.pdf and for duplicates see 2013-001_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. DMSP-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. For details on analysis see document 2013-001_DMS_Report.pdf. 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 2013-001_DIC.pdf, 2013-001_ALK.pdf, and 2013-001_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 ~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 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. The Oxygen:Dissolved:CTD calibration was done using the method described in the Sea-Bird Application Note #64-2 (Sea-Bird_64-2_Feb2010.pdf). For details on the processing see processing report: 2013-001-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-- ---12--- 13 --14- 15 --16-- 17 --18- 19 !Samp Bo Bo Pressu Temperat Salinity Sigma-t: Trans Oxygen Oxyge Fluores Salinity Fl Nitra Fl Phosph Fl Silic Fl !le_ tt tt re:CTD ure:CTD :CTD CTD missi :Disso n:Dis cence: :Bottle ag te_pl ag ate: ag ate: ag !Numb ~u ~u vity: lved: solve CTD: ~o ~Nitr ~o Bottle ~o Bottl ~o !er mb en CTD CTD: d:CTD Seapoin tt ite:B tt tt e tt ! er ce Volume :Mass t le ottle le le le !---- -- -- ------ -------- -------- -------- ----- ------ ----- ------- -------- -- ----- -- ------ -- ----- -- *END OF HEADER 307 12 12 10.0 5.4044 32.6307 25.7773 60.6 7.16 311.8 0.537 -99.0000 0 -99.0 0 -99.00 0 -99.0 0 306 11 11 10.1 5.4030 32.6313 25.7780 60.6 7.17 312.0 0.542 32.6313 0 16.7 0 1.46 0 25.3 0 305 10 10 10.3 5.4028 32.6314 25.7781 60.6 7.16 311.6 0.540 -99.0000 0 -99.0 0 -99.00 0 -99.0 0 304 9 9 501.2 3.6675 34.1380 27.1597 65.9 0.63 27.5 0.091 -99.0000 0 -99.0 0 -99.00 0 -99.0 0 303 8 8 500.9 3.6675 34.1380 27.1597 65.9 0.63 27.5 0.091 34.1360 0 44.1 0 3.14 0 116.5 0 302 7 7 500.7 3.6679 34.1378 27.1595 65.9 0.63 27.5 0.093 -99.0000 0 -99.0 0 -99.00 0 -99.0 0 301 6 6 999.3 2.8350 34.3906 27.4392 66.0 0.52 22.5 0.088 -99.0000 0 -99.0 0 -99.00 0 -99.0 0 300 5 5 999.5 2.8340 34.3907 27.4394 66.0 0.52 22.5 0.087 34.3890 0 45.3 0 3.21 0 149.7 0 299 4 4 1000.0 2.8329 34.3911 27.4398 66.0 0.52 22.5 0.088 -99.0000 0 -99.0 0 -99.00 0 -99.0 0 298 3 3 1999.1 1.9136 34.5880 27.6741 66.1 1.33 57.8 0.085 -99.0000 0 -99.0 0 -99.00 0 -99.0 0 297 2 2 1999.3 1.9135 34.5879 27.6740 66.1 1.33 57.7 0.085 34.5866 0 43.6 0 3.05 0 175.0 0 296 1 1 1999.0 1.9137 34.5879 27.6740 66.1 1.33 57.7 0.084 -99.0000 0 -99.0 0 -99.00 0 -99.0 0
