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-- ---23-- ---24-- ---25-- ---26-- ---27-- ---28-- ---29-- ---30-- ---31-- ---32-- ---33-- ---34-- ---35-- ---36-- ---37-- ---38-- ---39-- ---40-- ---41-- ---42-- ---43-- ---44-- ---45-- ---46-- ---47-- 48 !Samp Bott Bott Pressu Temperat Salinity Sigma-t: Trans Oxygen Oxyge Fluores Salinity Fl Nitra Fl Phosph Fl Silic Fl Chloro Fl Phaeo- HPLC: HPLC: HPLC: HPLC: HPLC: HPLC: HPLC: HPLC: HPLC: HPLC: HPLC: HPLC: HPLC: HPLC: HPLC: HPLC: HPLC: HPLC: HPLC: HPLC: HPLC: HPLC: HPLC: HPLC:B- HPLC: Fl !le_ le_ le:F re:CTD ure:CTD :CTD CTD missi :Disso n:Dis cence: :Bottle ag te_pl ag ate: ag ate: ag phyll: ag Pigmen Chl-c3: Chlide- MgDVP: Chl-c2: Chl-c1: Me- Peri: Pheide- But- Fuco: Neo: Pras: Viola: Hex- Diadino Allo: Diato: Zea: Lut: Chl-b: DVChl- Chl-a: Phe: Car: TChl-a: ag !Numb Numb ~ng_ vity: lved: solve CTD: ~o ~Nitr ~o Bottle ~o Bottl ~o Extrac ~o t:Extr Bottle a: Bottle Bottle Bottle chlide: Bottle a: fuco: Bottle Bottle Bottle Bottle fuco: :Bottle Bottle Bottle Bottle Bottle Bottle a: Bottle Bottle Bottle Bottle : !er er Sequ CTD CTD: d:CTD Wetlabs tt ite:B tt tt e tt ted: tt acted: Bottle Bottle Bottle Bottle Bottle Bottle HP ! ence Volume :Mass le ottle le le le Bottle le Bottle LC !---- ---- ---- ------ -------- -------- -------- ----- ------ ----- ------- -------- -- ----- -- ------ -- ----- -- ------ -- ------ ------- ------- ------- ------- ------- ------- ------- ------- ------- ------- ------- ------- ------- ------- ------- ------- ------- ------- ------- ------- ------- ------- ------- ------- ------- -- *END OF HEADER 198 2 2 5.1 10.8909 32.3264 24.7394 54.6 6.61 288.1 0.299 32.3275 0 3.5 0 0.69 0 9.4 0 0.44 0 0.07 0.024 0.000 0.000 0.036 0.000 0.000 0.000 0.000 0.025 0.038 0.002 0.001 0.000 0.115 0.046 0.011 0.017 0.055 0.008 0.043 0.000 0.325 0.000 0.009 0.325 36 197 1 1 54.1 7.5541 32.5216 25.4171 56.5 7.07 307.7 2.404 -99.0000 0 7.5 0 0.93 0 12.5 0 0.55 0 0.13 0.091 0.000 0.002 0.079 0.000 0.000 0.000 0.000 0.065 0.095 0.000 0.000 0.005 0.252 0.012 0.000 0.001 0.011 0.000 0.020 0.000 0.388 0.000 0.002 0.388 6
