Sample Number 348: SAL:Bottle - duplicates Chauvenet outlier - value 34.6729 rejected as outlier in COMPARE. Sample Number 361: SAL:Bottle - outlier in COMPARE, SAL:CTD data very steady, local gradient low. Sample Number 370: Bottle Number 24 - top valve not closed; SAL:Bottle - salt on cap; looks ok in COMPARE but too shallow to be signficant; OXY:Bottle - bubble on lens but looks ok in comparison to OXY:CTD. Analysis methods: ----------------- Salinity samples were collected in glass bottles and analyzed on Guildline Autosal model 8400B, S/N 68572, at IOS. Salinometers are standardized with IAPSO standard seawater. For details on duplicate analysis see file 2011-026_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 on duplicate analysis see file 2011-026_OXY.pdf. Nutrient samples were collected in plastic tubes. Most samples were stored frozen and later analysed at IOS. Deep Silicate samples (400 dbar and deeper) were analyzed cool at IOS. An Astoria analyzer was used following methods described in Barwell-Clarke and Whitney (1996). For precision and duplicate analysis see file 2011-026_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 calibrated annually with commercially pure chlorophyll a standard (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). Phaeopigment data are provided for information only and no quality flags are assigned to them. For details on duplicates see file 2011-026_CHL.pdf. 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 2011-026_DMS_report.pdf and for duplicates see file 2011-026_DMS.pdf. The minimum detectable level for DMSP-D:Bottle is 0.1 nM, so “0” values should be interpreted as <0.1. The minimum detectable level for DMSP-T:Bottle in this file is 0.1 nM from 0 to 20 dbar, and 1 nM from 20 to 200 dbar, so “0” values should be interpreted as < those values. DMSP data are limited to 2 significant figures. For details on analysis see document 2011-026_DMS_report.pdf. 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 ~2 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.

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 SeaBird Application Note #64-2 (Sea-Bird_64-2_Feb2010.pdf). For details on the processing see processing report: 2011-026-proc.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 $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 Bott Bott Pressu Temperat Salinity Sigma-t: Trans Oxygen Oxyge Fluores Salinity Fl Oxygen: Oxyge Fl Nitra Fl Phosph Fl Silic Fl !le_ le_ le:F 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 Numb ~ng_ vity: lved: solve CTD: ~o ed: ~ed:B ~o ~Nitr ~o Bottle ~o Bottl ~o !er er Sequ CTD CTD: d:CTD Wetlabs tt Bottle: ottle tt ite:B tt tt e tt ! ence Volume :Mass le Volume :Mass le ottle le le le !---- ---- ---- ------ -------- -------- -------- ----- ------ ----- ------- -------- -- ------- ----- -- ----- -- ------ -- ----- -- *END OF HEADER 370 24 24 4.7 9.5493 32.5955 25.1747 58.6 6.76 294.3 0.449 32.6032 3 6.754 294.1 3 6.7 3 0.85 3 12.1 3 369 23 23 9.8 9.5472 32.5954 25.1749 58.6 6.73 293.0 0.611 32.5962 0 6.735 293.3 0 6.7 0 0.88 0 12.0 0 368 22 22 24.6 9.5450 32.5945 25.1746 58.6 6.72 292.6 0.800 32.5975 0 6.735 293.3 0 6.7 0 0.88 0 12.0 0 367 21 21 50.4 7.6074 32.6136 25.4819 60.0 7.03 305.9 1.402 32.6169 0 7.027 305.9 0 7.6 0 0.94 0 12.5 0 366 20 20 75.6 6.9569 32.6535 25.6023 61.1 6.94 302.1 1.358 32.6511 0 6.951 302.6 0 8.8 0 0.99 0 12.9 0 365 19 19 100.9 6.7601 33.1608 26.0280 63.1 5.82 253.4 0.536 33.1612 0 5.855 254.8 6 16.1 0 1.35 0 20.1 0 364 18 18 125.3 6.7035 33.7479 26.4983 64.1 4.61 200.4 0.107 33.7437 0 4.621 201.0 0 23.9 0 1.75 0 33.2 0 363 17 17 150.6 6.2837 33.8130 26.6045 64.1 4.23 183.8 0.067 33.8186 0 4.231 184.0 0 26.7 6 1.94 6 40.7 6 362 16 16 174.8 5.8645 33.8163 26.6600 64.1 3.91 169.9 0.062 33.8185 0 3.932 171.0 0 28.6 0 2.07 0 45.9 0 361 15 15 200.6 5.5935 33.8175 26.6941 64.2 3.62 157.2 0.062 33.8318 3 3.618 157.3 0 30.4 0 2.19 0 50.5 0 360 14 14 249.7 4.9411 33.8444 26.7916 64.1 2.73 118.7 0.055 33.8477 0 2.727 118.6 0 34.9 0 2.50 0 63.1 0 359 13 13 298.2 4.7052 33.8773 26.8440 64.1 2.28 98.9 0.058 33.8771 0 2.276 99.0 0 37.2 0 2.63 0 70.2 0 358 12 12 400.0 4.3806 33.9851 26.9648 64.4 1.38 59.9 0.039 33.9844 0 1.372 59.6 0 40.9 0 2.94 0 85.4 0 357 11 11 600.0 3.8405 34.1566 27.1572 64.4 0.59 25.8 0.046 34.1572 0 0.575 25.0 0 44.4 6 3.14 6 110.2 6 356 10 10 799.4 3.4087 34.2775 27.2960 64.4 0.39 16.9 0.034 34.2799 0 0.352 15.3 0 45.0 0 3.25 0 127.3 0 355 9 9 1001.1 3.0124 34.3701 27.4069 64.4 0.31 13.3 0.041 34.3701 0 0.277 12.0 0 45.6 0 3.21 0 141.8 0 354 8 8 1248.8 2.6642 34.4437 27.4967 64.4 0.35 15.2 0.042 34.4484 0 0.326 14.2 0 45.8 0 3.30 0 153.9 0 353 7 7 1499.3 2.3887 34.4989 27.5643 64.5 0.55 23.8 0.033 34.5096 0 0.499 21.7 0 45.5 0 3.23 0 161.9 0 352 6 6 2000.3 1.9314 34.5899 27.6742 64.5 1.35 58.6 0.031 34.5971 0 1.309 56.9 0 43.3 0 3.02 0 171.8 0 351 5 5 2499.7 1.7283 34.6302 27.7222 64.5 1.94 84.4 0.032 34.6399 0 1.918 83.3 6 41.7 0 2.88 0 173.6 0 350 4 4 2998.8 1.5953 34.6552 27.7522 64.5 2.45 106.4 0.017 34.6611 0 2.440 106.0 0 40.0 0 2.83 0 173.5 0 349 3 3 3501.5 1.5753 34.6659 27.7623 64.2 2.67 115.9 0.022 34.6646 0 2.678 116.3 0 39.4 0 2.79 0 175.2 0 348 2 2 3501.5 1.5755 34.6659 27.7622 64.2 2.67 115.8 0.031 34.6658 2 2.679 116.4 0 39.5 0 2.79 0 175.3 0 347 1 1 3682.0 1.5755 34.6688 27.7646 63.3 2.71 117.9 0.029 34.6884 3 2.717 118.0 0 39.2 0 2.77 0 176.5 0
