Sample Number 164: Oxygen:Dissolved:Bottle - titration noisy rendering endpoint slightly ambiguous. Adjusted endpoint with aid of regression analysis. Silicate:Bottle - cool tube broken. Samples Number 165 and 181: Oxygen:Dissolved:Bottle - titration was not flat at end. Regression analysis pointed to an early endpoint. Adjusted endpoint. Sample Number 166: Silicate:Bottle - cool tube broken. Sample Number 167: Oxygen:Dissolved:Bottle - an odd step feature near end of titration. Endpoint difficult to determine accurately. No adjustment to the endpoint. Silicate:Bottle - cool duplicate tube broken. Analysis methods: ----------------- Salinity samples were collected in 200 ml type ll glass bottles with disposable plastic inserts 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 within 2 to 21 days after collection. For details on duplicate analysis see file 2013-01_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 2013-01_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 2013-01_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 2013-01_CHL.pdf. Flags and comments apply to chlorophyll values only. No flags or comments are assigned for Phaeopigment values. 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 2013-01_DMS_Report.pdf and for duplicates see 2013-01_DMS.pdf. References: 1.

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_Jun2012.pdf) with a modification allowing a small offset. For further processing details see the processing report 2013-01-proc.pdf. $REMARKS Flag channels were initialized with zeros. Non-zero values have the following significance: ---------------------------------------------------------------------------------- 1 = Sample for this measurement was collected but not analyzed. Sample lost. 2 = Acceptable measurement. 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 Dissolv n:Dis ag te_pl ag ate: ag ate: ag !Numb ~u ~u vity: lved: solve CTD: ~o ed: ~ed:B ~o ~Nitr ~o Bottle ~o Bottl ~o !er mb en CTD CTD: d:CTD Seapoin tt Bottle: ottle tt ite:B tt tt e tt ! er ce Volume :Mass t le Volume :Mass le ottle le le le !---- -- -- ------ -------- -------- -------- ----- ------ ----- ------- -------- -- ------- ----- -- ----- -- ------ -- ----- -- *END OF HEADER 184 24 24 6.1 7.0932 32.5693 25.5178 60.3 6.92 301.2 0.741 32.5716 0 6.894 300.1 0 12.7 0 1.23 0 19.3 0 183 23 23 10.5 7.0943 32.5693 25.5176 60.4 6.92 301.5 0.733 -99.0000 0 6.894 300.1 0 12.6 0 1.20 0 19.4 0 182 22 22 25.0 7.0860 32.5692 25.5187 60.5 6.91 300.9 0.717 -99.0000 0 6.904 300.6 0 12.7 0 1.22 0 19.4 0 181 21 21 50.9 7.0768 32.5692 25.5199 61.0 6.90 300.4 0.684 -99.0000 0 6.870 299.1 2 12.8 6 1.22 6 19.4 6 180 20 20 75.1 7.0773 32.5692 25.5198 61.2 6.89 299.9 0.657 -99.0000 0 6.883 299.6 6 12.7 0 1.23 0 19.3 0 179 19 19 101.2 6.5864 32.6685 25.6627 63.7 6.70 291.4 0.256 -99.0000 0 6.762 294.3 0 14.2 0 1.30 0 20.7 0 178 18 18 124.6 5.6005 33.0745 26.1055 65.1 6.02 262.0 0.102 -99.0000 0 6.011 261.5 0 20.2 0 1.63 0 29.5 0 177 17 17 149.9 5.9692 33.5767 26.4577 65.1 4.79 208.3 0.089 -99.0000 0 4.895 212.9 0 24.4 0 1.81 0 36.7 0 176 16 16 175.6 5.9754 33.7857 26.6220 65.1 4.08 177.3 0.087 -99.0000 0 4.068 176.9 6 27.8 0 2.00 0 45.6 0 175 15 15 199.5 5.7505 33.8272 26.6827 65.1 3.69 160.7 0.085 -99.0000 0 3.707 161.2 0 29.8 0 2.15 0 50.9 0 174 14 14 250.0 5.0141 33.8558 26.7923 65.2 2.77 120.4 0.087 -99.0000 0 2.770 120.4 0 34.8 0 2.49 0 65.7 0 173 13 13 300.7 4.7161 33.8955 26.8572 65.4 2.22 96.4 0.085 -99.0000 0 2.220 96.5 6 37.5 0 2.67 0 73.9 0 172 12 12 399.0 4.3458 33.9985 26.9792 65.8 1.45 62.9 0.088 -99.0000 0 1.447 62.9 0 40.6 0 2.90 0 89.5 0 171 11 11 600.8 3.8419 34.1591 27.1591 66.0 0.59 25.8 0.085 -99.0000 0 0.593 25.8 0 43.9 0 3.13 0 112.8 0 170 10 10 799.1 3.3936 34.2769 27.2969 66.0 0.38 16.7 0.085 -99.0000 0 0.369 16.0 0 44.9 0 3.21 0 130.3 0 169 9 9 1000.5 3.0215 34.3751 27.4100 66.0 0.28 12.3 0.084 34.3745 6 0.281 12.2 0 45.5 0 3.26 0 145.1 0 168 8 8 1251.0 2.6751 34.4484 27.4995 66.1 0.34 14.6 0.083 34.4492 0 0.313 13.6 0 45.7 0 3.25 0 156.6 0 167 7 7 1501.6 2.3555 34.5081 27.5745 66.1 0.59 25.7 0.083 34.5087 0 0.613 26.6 3 45.0 6 3.20 6 166.0 2 166 6 6 2001.8 1.9135 34.5945 27.6793 66.2 1.40 60.7 0.081 34.5957 6 1.389 60.3 6 43.1 0 3.03 0 -99.0 1 165 5 5 2500.9 1.7370 34.6294 27.7209 66.3 1.93 83.8 0.082 34.6306 0 1.908 82.9 2 41.7 0 2.93 0 177.7 0 164 4 4 3003.2 1.6086 34.6532 27.7496 66.2 2.43 105.4 0.082 34.6536 6 2.427 105.4 3 40.4 0 2.82 0 -99.0 1 163 3 3 3501.7 1.5727 34.6653 27.7620 65.8 2.70 117.3 0.083 34.6657 0 2.693 117.0 0 39.5 0 2.74 0 178.3 0 162 2 2 3502.0 1.5729 34.6652 27.7619 65.8 2.70 117.2 0.083 -99.0000 0 2.698 117.2 0 39.7 0 2.76 0 177.6 0 161 1 1 3679.7 1.5770 34.6672 27.7632 65.7 2.75 119.3 0.083 -99.0000 0 2.734 118.8 3 39.3 0 2.74 0 177.4 0
