They were analyzed in a temperature-controlled lab on a Guildline 8400B Salinometer (S/N 68572) standardized with IAPSO standard seawater 22 to 40 days after collection. The duplicate analysis is in file 2013-017_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 2013-017_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 2013-017_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 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 on board ship in June or in July-August at IOS in a controlled temperature lab. A number of samples were analyzed on a different fluorometer (plankton lab) and values seem to be slightly lower than those analyzed on Water Properties fluorometer. These are flagged. 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 2013-017_CHL.pdf Flags and comments apply to chlorophyll values only; phaeopigment data are provided for information only and no quality flags are assigned to them. 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 ~6-8 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. Salinity:CTD was lower than Salinity:Bottle by an average of ~0.0017. For details on how the transmissivity calibration parameters were calculated see the document Transmissivity_Calculation.pdf. The Oxygen:Dissolved:CTD data are considered of lower quality than usual which is likely due to noisy secondary temperature and/or problems in the secondary plumbing. Problems were less severe during bottle stops except for casts 0018 to 0022 from which the Oxygen:Dissolved:CTD channels were removed. WARNING: SeaPoint Fluorometer #2228 malfunctioned during the latter half of 2013. There were large values at great depth that got steadily higher through the year until it was removed from service. The data have been left in the file so researchers can see the shape of the profile. Comparison with extracted chlorophyll is recommended. For details on the processing see the report: 2013-017-proc.doc. $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-- !Samp Bo Bo Pressu Temperat Salinity Sigma-t: Trans Oxygen Oxyge Fluores PAR: !le_ tt tt re:CTD ure:CTD :CTD CTD missi :Disso n:Dis cence: CTD !Numb ~u ~u vity: lved: solve CTD: !er mb en CTD CTD: d:CTD Seapoin ! er ce Volume :Mass t !---- -- -- ------ -------- -------- -------- ----- ------ ----- ------- ------ *END OF HEADER 319 21 19 5.0 10.1293 32.3887 24.9180 53.4 6.69 291.6 1.580 149.6 318 20 18 5.1 10.1294 32.3887 24.9180 53.5 6.70 291.8 1.596 148.0 317 19 17 4.9 10.1294 32.3886 24.9179 53.4 6.69 291.3 1.581 140.7 316 18 16 5.3 10.1294 32.3887 24.9180 53.6 6.70 291.8 1.618 138.7 315 17 15 4.6 10.1294 32.3886 24.9179 53.5 6.70 291.7 1.611 162.2 314 16 14 5.3 10.1295 32.3886 24.9179 53.6 6.70 291.8 1.639 131.2 313 15 10 38.9 8.6969 32.4048 25.1590 57.2 6.90 300.4 2.504 3.5 312 14 9 38.5 8.7076 32.4037 25.1565 57.2 6.91 301.0 2.533 3.6 311 13 8 39.6 8.6674 32.4060 25.1644 57.5 6.90 300.6 2.415 3.2 310 12 7 38.1 8.6931 32.4041 25.1590 57.1 6.90 300.7 2.516 3.9 309 11 6 38.6 8.6976 32.4045 25.1586 56.5 6.89 299.9 2.400 3.6 308 10 5 39.4 8.6446 32.4064 25.1681 55.0 6.90 300.4 2.388 3.2 307 9 4 38.9 8.6662 32.4052 25.1639 57.1 6.89 300.3 2.443 3.4 306 8 3 38.3 8.6830 32.4048 25.1611 57.2 6.92 301.5 2.491 3.7 305 7 2 38.7 8.6942 32.4044 25.1590 57.1 6.90 300.5 2.411 3.6 304 6 13 25.0 10.1274 32.3882 24.9180 53.4 6.69 291.5 2.227 13.2 303 5 12 25.9 10.1291 32.3881 24.9176 53.4 6.70 291.6 2.231 12.0 302 4 11 24.9 10.1288 32.3880 24.9176 53.7 6.70 291.7 2.424 13.1 301 3 22 3.1 10.1300 32.3887 24.9179 52.9 6.70 291.9 1.518 220.3 300 2 21 3.0 10.1299 32.3873 24.9168 53.3 6.70 292.0 1.566 220.0 299 1 1 38.9 8.6690 32.4055 25.1637 57.3 6.90 300.4 2.480 3.5
