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 2011-001_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. A shift in the Oxygen:CTD standardization parameters occurred between events 0032 and 0044; this was not investigated to determine if the resultant change in Thiosulfate normality was real, or the result of a shift in lab temperature. Checks of the fit of Oxygen:CTD against Oxygen:Bottle suggest that the titrated values from the first part of the cruise are lower than those of the latter part by about 0.02 ml/l. For details on duplicate analysis see file 2011-001_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 2011-001_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 on board ship in a controlled temperature lab and at IOS. 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 2011-001_CHL.pdf. Phaeopigment data are provided for information only and no quality flags are assigned to them. 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 2011-001_DMS_report.pdf and for duplicates see 2011-001_DMS.pdf. The minimum detectable level for DMSP-D:Bottle is 0.10 nmol/l, so “0” values should be interpreted as <0.10 nmol/l. 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 2011-001_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 ~3 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. 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). The Oxygen:Dissolved:CTD channel was corrupted for all or parts of events 0007, 0010, 0015, 0017, 0018, 0019 and 0021. For details on the processing see processing report: 2011-001-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-- !Samp Bott Bott Pressu Temperat Salinity Sigma-t: Trans Oxygen Oxyge Fluores PAR: !le_ le_ le:F re:CTD ure:CTD :CTD CTD missi :Disso n:Dis cence: CTD !Numb Numb ~ng_ vity: lved: solve CTD: !er er Sequ CTD CTD: d:CTD Seapoin ! ence Volume :Mass t !---- ---- ---- ------ -------- -------- -------- ----- ------ ----- ------- ------ *END OF HEADER 266 24 17 39.9 7.4741 32.5836 25.4770 61.5 6.82 297.1 1.021 10.2 265 23 16 39.5 7.4736 32.5837 25.4771 61.5 6.82 297.0 1.026 10.1 264 22 24 2.8 7.4781 32.5834 25.4763 61.4 6.83 297.3 0.733 114.1 263 21 23 10.4 7.4727 32.5834 25.4770 61.3 6.83 297.4 0.943 42.6 262 20 22 10.4 7.4730 32.5834 25.4770 61.3 6.83 297.2 0.917 43.1 261 19 21 19.1 7.4752 32.5834 25.4767 61.3 6.83 297.3 1.019 26.5 260 18 20 19.7 7.4749 32.5835 25.4768 61.3 6.82 297.1 1.044 26.3 259 17 19 29.8 7.4754 32.5834 25.4766 61.5 6.82 297.1 1.016 17.8 258 16 18 30.1 7.4749 32.5834 25.4767 61.5 6.82 297.0 1.019 17.8 257 15 15 49.9 7.4724 32.5835 25.4771 61.5 6.82 296.9 1.038 5.6 256 14 14 49.8 7.4727 32.5835 25.4771 61.5 6.82 296.8 1.040 5.6 255 13 13 75.6 7.4763 32.5840 25.4770 61.6 6.81 296.5 1.040 1.4 254 12 12 76.7 7.4759 32.5841 25.4771 61.5 6.81 296.3 1.048 1.3 253 11 11 100.1 7.0892 32.9210 25.7951 64.1 6.36 276.6 0.117 0.5 252 10 10 100.1 7.0728 32.9329 25.8067 64.1 6.37 277.1 0.115 0.5 251 9 9 150.4 6.7744 33.7607 26.4989 64.4 4.70 204.6 0.015 0.1 250 8 8 151.0 6.7574 33.7729 26.5108 64.4 4.71 204.8 0.014 0.0 249 7 7 198.5 5.8813 33.8142 26.6563 64.2 4.04 175.6 0.013 0.0 248 6 6 199.2 5.8728 33.8140 26.6572 64.2 4.04 175.7 0.016 0.0 247 5 5 299.0 4.6630 33.8562 26.8319 64.3 2.48 108.0 0.018 0.0 246 4 4 298.3 4.6677 33.8545 26.8300 64.3 2.49 108.2 0.017 0.0 245 3 3 401.5 4.1830 33.9643 26.9692 64.4 1.42 61.9 0.022 0.0 244 2 2 498.0 4.0603 34.0767 27.0712 64.4 0.93 40.5 0.023 0.0 243 1 1 498.8 4.0589 34.0779 27.0724 64.4 0.93 40.4 0.024 0.0
