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-- --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 679 12 12 2.2 6.7506 32.6930 25.6607 58.3 7.11 309.5 0.172 0.354 505.8 678 11 11 6.9 6.7418 32.6938 25.6625 58.2 7.11 309.4 0.248 0.500 247.0 677 10 10 10.9 6.7176 32.6939 25.6657 58.1 7.12 309.9 0.353 0.709 163.8 676 9 9 21.9 6.4545 32.6980 25.7029 56.6 7.18 312.5 0.631 1.247 68.5 675 8 8 31.6 6.1536 32.7023 25.7442 55.4 7.24 315.1 0.994 1.901 32.7 674 7 7 51.3 5.7932 32.7148 25.7981 59.8 7.22 314.1 0.923 1.777 6.4 673 6 6 76.0 5.2057 32.7155 25.8671 64.2 7.20 313.2 0.532 0.997 0.9 672 5 5 100.9 4.7322 32.7506 25.9472 66.5 7.07 307.7 0.114 0.256 0.3 671 4 4 126.7 4.5178 33.2937 26.4011 66.9 5.29 230.3 0.049 0.154 0.1 670 3 3 152.5 4.2580 33.6864 26.7404 67.0 3.61 156.8 0.035 0.128 0.0 669 2 2 201.7 3.9638 33.7573 26.8271 67.2 2.72 118.3 0.037 0.137 0.0 668 1 1 251.1 3.8919 33.8358 26.8968 67.1 2.09 90.7 0.037 0.140 0.0
