Sample Number 217: OXY:Bottle - colourimeter issues due to operator error for one duplicate. Sample Number 218: OXY:Bottle - bubble on lens. Titration a mess. Endpoint ambiguous. Sample Number 220: OXY:Bottle - very gradual change in slopes. Difficult to determine endpoint. 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 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--- 13 --14-- --15- 16 --17- 18 --19-- 20 --21- 22 !Samp Bo Bo Pressu Temperat Salinity Sigma-t: Trans Oxygen Oxyge Fluores Salinity Fl Oxygen Oxyge Fl Nitra Fl Phosph Fl Silic Fl !le_ tt tt re:CTD ure:CTD :CTD CTD missi :Disso n:Dis cence: :Bottle ag :Disso n:Dis ag te_pl ag ate: ag ate: ag !Numb ~u ~u vity: lved: solve CTD: ~o lved:B ~ed:B ~o ~Nitr ~o Bottle ~o Bottl ~o !er mb en CTD CTD: d:CTD Seapoin tt ottle: ottle tt ite:B tt tt e tt ! er ce Volume :Mass t le Volume :Mass le ottle le le le !---- -- -- ------ -------- -------- -------- ----- ------ ----- ------- -------- -- ------ ----- -- ----- -- ------ -- ----- -- *END OF HEADER 232 23 23 4.8 11.0270 32.2152 24.6290 56.2 6.61 288.0 1.062 32.2190 0 6.59 287.2 0 4.7 0 0.78 0 10.3 0 231 22 22 10.4 11.0258 32.2147 24.6288 56.3 6.61 287.8 1.050 -99.0000 0 6.59 287.2 0 4.7 0 0.78 0 10.3 0 230 21 21 24.7 10.3818 32.2742 24.7863 56.6 6.73 293.3 1.263 -99.0000 0 6.71 292.2 0 5.8 0 0.84 0 11.4 0 229 20 20 49.9 7.4384 32.4865 25.4056 61.8 6.65 289.5 0.916 -99.0000 0 6.68 290.9 6 11.6 0 1.17 0 16.9 0 228 19 19 75.5 6.8394 32.7677 25.7078 63.9 6.05 263.4 0.688 -99.0000 0 6.07 264.0 0 17.0 0 1.45 0 22.9 0 227 18 18 100.1 7.0125 33.0282 25.8899 64.0 5.17 225.1 0.645 -99.0000 0 5.18 225.3 0 20.5 6 1.63 6 27.1 6 226 17 17 124.7 7.0227 33.4031 26.1837 64.0 4.25 185.1 0.629 -99.0000 0 4.26 185.1 0 24.8 0 1.86 0 33.2 0 225 16 16 150.2 6.9558 33.6916 26.4200 64.0 3.53 153.4 0.625 -99.0000 0 3.52 153.2 6 28.3 0 2.07 0 39.4 0 224 15 15 175.8 6.7246 33.7950 26.5326 64.1 3.35 145.7 0.623 -99.0000 0 3.33 144.8 0 29.6 0 2.11 0 43.1 0 223 14 14 201.2 6.3136 33.8141 26.6016 64.1 3.82 166.3 0.624 -99.0000 0 3.78 164.3 0 28.8 0 2.03 0 44.3 0 222 13 13 249.1 5.7316 33.9011 26.7434 64.5 2.52 109.5 0.632 -99.0000 0 2.52 109.5 0 34.9 0 2.45 0 59.2 0 221 12 12 299.9 5.2567 33.9174 26.8131 64.7 2.06 89.3 0.637 -99.0000 0 2.11 91.7 0 37.5 0 2.62 0 67.0 0 220 11 11 399.6 4.4924 33.9674 26.9388 65.1 1.64 71.2 0.641 -99.0000 0 1.64 71.5 3 40.5 0 2.83 0 82.6 0 219 10 10 600.2 4.1838 34.1647 27.1284 65.3 0.45 19.6 0.648 -99.0000 0 0.45 19.6 0 44.8 0 3.17 0 104.8 0 218 9 9 800.4 3.6403 34.2859 27.2801 65.2 0.28 12.0 0.649 -99.0000 0 0.29 12.4 4 45.7 0 3.25 0 123.6 0 217 8 8 999.8 3.2127 34.3679 27.3866 65.3 0.25 11.0 0.648 34.3687 6 0.25 10.6 36 46.2 0 3.27 0 137.7 0 216 7 7 1249.6 2.7647 34.4524 27.4948 65.3 0.38 16.4 0.642 -99.0000 5 -99.00 -99.0 5 -99.0 5 -99.00 5 -99.0 5 215 6 6 1501.0 2.3357 34.5165 27.5828 65.4 0.69 29.8 0.624 34.5182 0 0.67 29.2 0 45.5 0 3.17 0 163.5 0 214 5 5 1999.7 1.9209 34.5907 27.6757 65.5 1.39 60.5 0.599 34.5936 0 1.37 59.6 0 43.7 0 3.03 0 172.7 0 213 4 4 2499.6 1.7459 34.6267 27.7180 65.3 1.90 82.7 0.581 34.6269 0 1.88 81.7 0 42.4 6 2.92 6 175.8 0 212 3 3 3000.6 1.6444 34.6479 27.7427 65.3 2.30 99.9 0.570 34.6488 6 2.29 99.3 6 41.4 0 2.84 0 176.1 0 211 2 2 3000.4 1.6443 34.6479 27.7427 65.3 2.30 99.9 0.569 -99.0000 0 2.29 99.6 0 41.4 0 2.84 0 176.3 0 210 1 1 3275.4 1.6656 34.6488 27.7418 65.1 2.32 100.7 0.576 -99.0000 0 2.34 101.7 0 41.3 0 2.83 0 176.7 0
