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. Full details of the duplicate analysis are in file 2012-12_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 2012-12_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 2012-12_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 see file 2012-12_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 2012-12_DMS_Report.pdf and for duplicates see file 2012-12_DMS.pdf. The minimum detectable level for Dimethylsulfoniopropionate_Dissolved:Bottle is 0.1 nM, so “0” values should be interpreted as <0.1. The minimum detectable level for Dimethylsulfoniopropionate_Total: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 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).

Non-zero values have the following significance: -------------------------------------------------------------------------------------- 1 = Sample for this measurement was drawn from water bottle but not analyzed (not normally used). 2 = Acceptable measurement (not normally used). 3 = Questionable measurement (no problem observed in sampling or analysis, but value is not trusted, nonetheless; includes outlyers). 4 = Bad measurement (known problem with sampling or analysis, but not serious enough to completely discard the value). 5 = Not reported (lost sample; unredeemably bad measurement). 6 = Mean of replicate measurements. 7 = Manual chromatographic peak measurement. 8 = Irregular digital chromatographic peak integration. 9 = Sample not drawn for this measurement from this bottle (not normally used). -------------------------------------------------------------------------------------- $END !-1-- 2- 3- --4--- ---5---- ---6---- ---7---- --8-- --9--- --10- ---11-- ---12-- !Samp Bo Bo Pressu Temperat Salinity Sigma-t: Trans Oxygen Oxyge Fluores Fluores !le_ tt tt re:CTD ure:CTD :CTD CTD missi :Disso n:Dis cence: cence: !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 785 22 22 2.4 6.5965 32.6891 25.6777 57.4 7.17 311.9 0.684 1.324 784 21 21 2.7 6.5990 32.6896 25.6777 57.4 7.16 311.8 0.689 1.283 783 20 20 2.2 6.5863 32.6891 25.6790 57.4 7.16 311.5 0.687 1.332 782 19 19 2.3 6.5760 32.6890 25.6802 57.5 7.18 312.3 0.711 1.338 781 18 18 2.3 6.5830 32.6903 25.6803 57.4 7.17 312.2 0.694 1.325 780 17 17 51.8 5.2819 32.7193 25.8615 64.1 7.19 313.0 0.532 0.974 779 16 16 51.5 5.2800 32.7191 25.8615 64.0 7.19 313.0 0.526 1.057 778 15 15 51.8 5.2762 32.7190 25.8619 64.1 7.19 312.9 0.516 1.107 777 14 14 51.7 5.2760 32.7192 25.8621 64.1 7.19 313.0 0.518 1.070 776 13 13 51.6 5.2782 32.7192 25.8618 64.1 7.19 313.0 0.525 1.074 775 12 12 101.3 3.9134 32.8326 26.0965 67.2 7.03 306.0 0.091 0.222 774 11 11 101.6 3.9124 32.8322 26.0963 67.1 7.03 305.9 0.093 0.193 773 10 10 101.5 3.9112 32.8322 26.0964 67.2 7.03 306.0 0.101 0.196 772 9 9 101.1 3.9135 32.8332 26.0970 67.2 7.03 305.9 0.090 0.205 771 8 8 101.5 3.9116 32.8320 26.0962 67.2 7.03 305.7 0.086 0.199 770 7 7 151.6 4.4196 33.6295 26.6782 67.0 4.14 180.1 0.048 0.138 769 6 6 151.7 4.4204 33.6290 26.6777 67.0 4.15 180.3 0.049 0.134 768 5 5 152.1 4.4195 33.6296 26.6783 67.0 4.15 180.5 0.047 0.143 767 4 4 151.6 4.4205 33.6291 26.6778 67.0 4.15 180.4 0.047 0.135 766 3 3 151.4 4.4216 33.6281 26.6769 67.0 4.14 180.1 0.047 0.136 765 2 2 202.0 4.0203 33.7322 26.8014 67.2 2.98 129.6 0.048 0.132 764 1 1 202.2 4.0201 33.7323 26.8015 67.2 2.98 129.5 0.049 0.144
