They were analyzed in a temperature-controlled lab on a Guildline 8400B Salinometer (S/N 68572) standardized with IAPSO standard seawater within 2 months after collection. The duplicate analysis is in file 2012-012_SAL.pdf. Oxygen samples were analyzed at sea 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). For details of the duplicate analysis see file 2012-012_OXY.pdf. Nutrient samples were collected in plastic tubes and analyzed at sea, except for the repeated P4 inbound samples. The repeated P4 inbound samples were frozen, or in the case of deep Silicate (400 dbar and deeper) stored cool, and analyzed at IOS. All samples were analyzed using an Astoria analyzer following methods described in Barwell-Clarke and Whitney (1996). See file 2012-012_NUT.pdf for duplicates and precision information. 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 2012-012_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 2012-012_DMS_Report.pdf and for duplicates see file 2012-012_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. For details on analysis see document 2012-012_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 ~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: ---------------------- Fluorescence, 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 Oxygen:Dissolved:CTD calibration was done using the method described in the Sea-Bird Application Note #64-2 (Sea-Bird_64-2_Jun2012.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-- !Samp Bo Bo Pressu Temperat Salinity Sigma-t: Trans Oxygen Oxyge Fluores Fluores PAR: !le_ tt tt re:CTD ure:CTD :CTD CTD missi :Disso n:Dis cence: cence: CTD !Numb ~u ~u vity: lved: solve CTD: CTD: !er mb en CTD CTD: d:CTD Seapoin Wetlabs ! er ce Volume :Mass t !---- -- -- ------ -------- -------- -------- ----- ------ ----- ------- ------- ------ *END OF HEADER 667 23 19 6.3 6.3896 32.6989 25.7119 57.8 7.14 311.0 0.708 1.428 37.3 666 22 16 11.6 6.3911 32.7006 25.7130 57.8 7.14 310.9 0.719 1.425 21.9 665 21 1 201.8 4.1950 33.7727 26.8156 57.8 2.93 127.3 0.714 0.133 0.0 664 20 24 3.8 6.3893 32.6986 25.7117 57.8 7.15 311.1 0.707 1.459 56.6 663 19 23 3.7 6.3891 32.6986 25.7117 57.9 7.15 311.2 0.709 1.417 57.3 662 18 22 3.8 6.3894 32.6987 25.7117 57.9 7.16 311.4 0.724 1.448 55.6 661 17 18 9.5 6.3897 32.6989 25.7119 57.8 7.15 311.0 0.703 1.408 26.7 660 16 15 16.9 6.3906 32.6997 25.7124 58.0 7.16 311.4 0.731 1.446 14.6 659 15 11 24.4 6.3922 32.7017 25.7138 57.9 7.15 311.1 0.728 1.423 8.7 658 14 10 33.2 6.3710 32.7042 25.7184 58.1 7.14 310.9 0.730 1.479 4.6 657 13 6 40.8 6.2412 32.7066 25.7367 58.1 7.15 311.2 0.739 1.493 2.7 656 12 5 60.3 5.3926 32.7258 25.8539 58.2 7.21 313.6 0.730 1.300 0.7 655 11 21 3.8 6.3893 32.6987 25.7118 58.3 7.15 311.2 0.722 1.413 54.8 654 10 20 3.5 6.3893 32.6989 25.7119 59.3 7.15 311.2 0.759 1.415 57.0 653 9 17 9.5 6.3891 32.6986 25.7117 58.9 7.15 311.2 0.744 1.396 26.8 652 8 14 16.8 6.3910 32.7003 25.7128 58.9 7.15 311.3 0.741 1.438 15.0 651 7 13 17.1 6.3910 32.7001 25.7126 59.9 7.15 311.1 0.776 1.448 14.4 650 6 12 24.4 6.3921 32.7016 25.7137 59.9 7.15 311.3 0.779 1.431 8.7 649 5 9 33.3 6.3849 32.7031 25.7158 63.2 7.14 310.9 0.713 1.444 4.5 648 4 8 33.1 6.3870 32.7029 25.7154 63.2 7.15 311.0 0.713 1.432 4.6 647 3 7 40.7 6.2447 32.7067 25.7363 63.1 7.15 311.3 0.708 1.548 2.7 646 2 4 60.3 5.3918 32.7257 25.8539 67.0 7.20 313.4 0.038 1.356 0.7 645 24 3 60.2 5.3924 32.7253 25.8536 57.1 7.21 313.6 0.729 1.302 0.7
