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 351 20 20 3.0 7.8712 32.7151 25.5242 60.5 6.97 303.4 0.409 0.835 223.1 350 19 19 2.8 7.8711 32.7151 25.5242 60.5 6.97 303.4 0.429 0.847 231.4 349 18 18 3.0 7.8712 32.7150 25.5241 60.6 6.96 303.1 0.429 0.896 226.2 348 17 17 2.8 7.8711 32.7150 25.5242 60.6 6.97 303.2 0.423 0.876 231.3 347 16 16 3.1 7.8709 32.7151 25.5243 60.3 6.97 303.3 0.434 0.859 213.2 346 15 15 3.3 7.8711 32.7151 25.5242 60.5 6.97 303.2 0.418 0.850 217.6 345 14 14 2.8 7.8709 32.7150 25.5242 60.4 6.96 303.0 0.413 0.848 227.5 344 13 13 2.8 7.8708 32.7150 25.5242 60.5 6.97 303.4 0.415 0.851 230.1 343 12 12 2.7 7.8708 32.7151 25.5243 60.1 6.97 303.2 0.407 0.843 241.3 342 11 11 2.9 7.8707 32.7151 25.5243 60.2 6.97 303.2 0.422 0.887 224.3 341 10 10 3.3 7.8706 32.7151 25.5243 59.9 6.96 303.2 0.436 0.902 205.2 340 9 9 10.7 7.8705 32.7152 25.5244 60.3 6.96 303.2 0.481 0.997 94.9 339 8 8 17.4 7.8661 32.7149 25.5248 60.2 6.97 303.6 0.532 1.117 53.2 338 7 7 17.1 7.8625 32.7150 25.5254 60.3 6.97 303.6 0.517 1.077 54.3 337 6 6 26.8 7.6568 32.7128 25.5529 59.9 7.03 305.9 0.761 1.506 27.7 336 5 5 36.6 7.4925 32.7129 25.5761 58.9 7.05 307.0 1.057 2.174 13.7 335 4 4 36.6 7.4871 32.7134 25.5772 58.2 7.05 306.9 1.076 2.126 13.5 334 3 3 44.5 7.0359 32.7207 25.6447 59.7 7.11 309.6 1.128 2.091 7.6 333 2 2 67.2 6.6030 32.7379 25.7153 64.3 6.97 303.1 0.504 1.042 1.5 332 1 1 67.4 6.6031 32.7376 25.7150 64.3 6.96 302.9 0.490 0.952 1.5
