Program crashed leading to an abortion of the titration. Severe outlier in comparison of titrated samples and Oxygen:Dissolved:CTD. Sample Number 200: Bottle Number 2 - air valve was open; OXY:Bottle - looks ok in comparison of titrated samples and Oxygen:Dissolved:CTD; SAL:Bottle - one duplicate sample was not sealed properly but duplication ok; looks ok in comparison with Salinity:CTD; PHOS:Bottle - questionable. Sample Number 206: SAL:Bottle - duplicate bottle was empty. It was labeled but not sampled. Sample Number 215: Bottle Number 171 - spigot was open; OXY:Bottle - looks ok in comparison of titrated samples and Oxygen:Dissolved:CTD. Sample Number 217: CHL:Bottle - lost approximately 50 ml. Sample Number 219: CHL:Bottle - dropped filter face down on the bench top after filtering. 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 within 9-11 days after the end of the cruise. The duplicate analysis is in file 2012-001_SAL.pdf. Oxygen samples were analyzed on an automated Winkler titration system (Brinkmann Dosimat model 765 and a PC950 Colorimeter controlled by AutoOxy software V3.4) with modifications based on Carpenter (1965) and adhering to WOCE protocols (Culberson 1991). All samples were analyzed at sea. For details of the duplicate analysis see file 2012-001_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 2012-001_NUT.pdf. NOTE: July 2013: A correction has been applied to Nitrate_plus_Nitrite:Bottle and Phosphate:Bottle data from deep-water cruises analyzed at IOS between 2009 and 2012. For details see the report: Corrections_to_Nitrate_and_Phosphate_Data_2009-2012.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 on board ship 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 duplicate samples see file 2012-001_CHL.pdf. 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 ~4 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 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 calibration of the Oxygen:Dissolved:CTD channel was done using the method described in the Sea-Bird Application Note #64-2 (Sea-Bird_64-2_Feb2010.pdf). Fluorescence data were recalibrated to correct an error in the scale factor used in the original conversion. The data are still considered nominal and are unedited. For details on the processing see processing report: 2012-001-proc.pdf.

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 --23-- 24 --25-- !Samp Bo Bo Pressu Temperat Salinity Sigma-t: Trans Oxygen Oxyge Fluores Salinity Fl Oxygen: Oxyge Fl Nitra Fl Phosph Fl Silic Fl Chloro Fl Phaeo- !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 phyll: ag Pigmen !Numb ~u ~u vity: lved: solve CTD: ~o ed: ~ed:B ~o ~Nitr ~o Bottle ~o Bottl ~o Extrac ~o t:Extr !er mb en CTD CTD: d:CTD Wetlabs tt Bottle: ottle tt ite:B tt tt e tt ted: tt acted: ! er ce Volume :Mass le Volume :Mass le ottle le le le Bottle le Bottle !---- -- -- ------ -------- -------- -------- ----- ------ ----- ------- -------- -- ------- ----- -- ----- -- ------ -- ----- -- ------ -- ------ *END OF HEADER 221 23 23 4.9 7.8850 32.6581 25.4775 63.6 6.72 292.6 0.479 32.6601 0 6.708 291.9 6 9.1 0 1.01 0 14.5 0 0.29 0 0.08 220 22 22 10.6 7.8732 32.6572 25.4785 63.6 6.72 292.6 0.788 -99.0000 0 6.707 291.9 0 9.1 0 0.97 0 14.4 0 0.28 6 0.08 219 21 21 25.1 7.8658 32.6559 25.4785 63.5 6.72 292.4 0.988 -99.0000 0 6.709 291.9 0 9.2 0 0.99 0 14.5 0 0.29 3 0.09 218 20 20 49.6 7.9229 32.6688 25.4804 64.4 6.69 291.2 0.921 -99.0000 0 6.681 290.7 0 9.1 0 0.99 0 14.2 0 0.28 0 0.09 217 19 19 75.5 7.9095 32.6666 25.4806 64.6 6.68 290.9 0.896 -99.0000 0 6.678 290.6 0 9.1 0 0.99 0 14.3 0 0.28 4 0.09 216 18 18 98.9 7.8369 32.8047 25.5995 66.4 6.35 276.5 0.438 -99.0000 0 6.416 279.1 0 10.6 0 1.06 0 15.0 0 0.12 0 0.05 215 17 17 124.6 7.3820 33.6526 26.3305 67.4 4.74 206.4 0.150 -99.0000 0 4.748 206.4 2 21.7 0 1.55 0 26.0 0 -99.00 0 -99.00 214 16 16 153.2 7.3189 33.8260 26.4757 67.4 4.46 193.9 0.129 -99.0000 0 4.476 194.6 0 23.7 6 1.65 6 30.6 6 -99.00 0 -99.00 213 15 15 173.3 7.1057 33.8647 26.5358 67.5 4.27 185.8 0.125 -99.0000 0 4.299 186.9 6 25.1 0 1.76 0 34.2 0 -99.00 0 -99.00 212 14 14 200.6 6.7644 33.8721 26.5881 67.4 4.05 176.1 0.129 -99.0000 0 4.074 177.1 0 26.7 0 1.86 0 38.7 0 -99.00 0 -99.00 211 13 13 250.4 6.1872 33.8769 26.6673 67.3 3.19 138.9 0.125 -99.0000 0 3.201 139.1 0 31.5 0 2.18 0 48.9 0 -99.00 0 -99.00 210 12 12 300.4 5.7176 33.9039 26.7473 67.4 2.44 106.1 0.125 -99.0000 0 2.449 106.5 0 35.4 0 2.48 0 58.2 0 -99.00 0 -99.00 209 11 11 400.9 5.0524 34.0060 26.9070 67.6 1.19 51.9 0.121 -99.0000 0 1.195 51.9 0 41.5 0 2.91 0 76.8 0 -99.00 0 -99.00 208 10 10 599.7 4.4069 34.1782 27.1154 67.8 0.36 15.8 0.117 -99.0000 0 0.359 15.6 0 45.2 0 3.21 0 99.6 0 -99.00 0 -99.00 207 9 9 799.1 3.7190 34.2945 27.2792 67.9 0.24 10.6 0.117 34.2940 0 0.235 10.2 0 46.5 0 3.19 0 120.4 0 -99.00 0 -99.00 206 8 8 999.8 3.2118 34.3824 27.3983 67.9 0.26 11.2 0.113 34.3819 2 0.247 10.7 0 46.6 0 3.17 0 136.0 0 -99.00 0 -99.00 205 7 7 1249.3 2.8092 34.4489 27.4881 67.9 0.37 16.0 0.113 -99.0000 0 0.365 15.9 0 46.6 0 3.18 0 148.4 0 -99.00 0 -99.00 204 6 6 1499.8 2.4147 34.5079 27.5694 68.0 0.64 28.0 0.108 -99.0000 0 0.634 27.5 6 46.1 0 3.08 0 158.6 0 -99.00 0 -99.00 203 5 5 2002.9 1.9561 34.5863 27.6694 68.0 1.36 59.0 0.100 34.5857 0 1.348 58.6 0 44.1 6 3.04 6 169.9 6 -99.00 0 -99.00 202 4 4 2500.4 1.7537 34.6265 27.7173 67.9 1.88 81.4 0.108 -99.0000 0 1.880 81.7 0 42.9 0 2.84 0 174.4 0 -99.00 0 -99.00 201 3 3 3000.4 1.6555 34.6471 27.7412 67.9 2.26 98.0 0.100 -99.0000 0 2.263 98.3 0 41.8 0 2.87 0 172.9 0 -99.00 0 -99.00 200 2 2 2997.8 1.6553 34.6471 27.7412 67.9 2.26 98.0 0.104 34.6476 26 2.263 98.3 2 41.8 0 2.78 3 173.7 0 -99.00 0 -99.00 199 1 1 3274.7 1.6735 34.6484 27.7409 67.6 2.28 98.9 0.100 -99.0000 0 -99.000 -99.0 5 41.9 6 2.92 6 173.6 6 -99.00 0 -99.00
