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-- --14- 15 --16-- 17 --18- 19 --20-- 21 --22-- --23-- 24 --25-- 26 --27-- 28 !Samp Bo Bo Pressu Temperat Salinity Sigma-t: Trans Oxygen Oxyge Fluores Fluores PAR: Nitra Fl Phosph Fl Silic Fl Chloro Fl Phaeo- Dimeth Fl Dimeth Fl Dimeth Fl !le_ tt tt re:CTD ure:CTD :CTD CTD missi :Disso n:Dis cence: cence: CTD te_pl ag ate: ag ate: ag phyll: ag Pigmen yl_ ag ylsulf ag ylsulf ag !Numb ~u ~u vity: lved: solve CTD: CTD: ~Nitr ~o Bottle ~o Bottl ~o Extrac ~o t:Extr Sulphi ~o ~ate_D ~s ~nate_ ~a !er mb en CTD CTD: d:CTD Seapoin Wetlabs ite:B tt tt e tt ted: tt acted: de: tt issolv ol Total: l: ! er ce Volume :Mass t ottle le le le Bottle le Bottle Bottle le ed:Bot ve Bottle Bo !---- -- -- ------ -------- -------- -------- ----- ------ ----- ------- ------- ------ ----- -- ------ -- ----- -- ------ -- ------ ------ -- ------ -- ------ -- *END OF HEADER 369 18 17 6.5 7.9412 32.7148 25.5139 59.7 6.98 303.8 0.141 0.515 167.8 -99.0 0 -99.00 0 -99.0 0 -99.00 0 -99.00 -99.00 0 -99.00 -99.00 368 17 16 6.7 7.9401 32.7147 25.5140 59.5 6.99 304.1 0.229 0.540 164.9 -99.0 0 -99.00 0 -99.0 0 0.31 6 0.07 -99.00 0 -99.00 -99.00 367 16 8 51.0 6.8628 32.7248 25.6710 59.5 7.09 308.7 0.236 2.059 22.8 -99.0 0 -99.00 0 -99.0 0 0.54 6 0.19 -99.00 0 -99.00 -99.00 366 15 6 60.9 6.7223 32.7276 25.6916 59.5 7.03 306.2 0.231 1.402 12.9 -99.0 0 -99.00 0 -99.0 0 0.43 6 0.24 -99.00 0 -99.00 -99.00 365 14 18 2.3 7.9926 32.7149 25.5066 59.5 6.97 303.6 0.237 0.320 285.6 11.3 0 1.16 0 17.2 0 0.31 0 0.07 0.93 0 0.00 0.00 364 13 15 6.4 7.9394 32.7149 25.5142 59.6 6.97 303.6 0.276 0.519 178.0 11.4 0 1.16 0 17.4 0 0.31 0 0.07 0.89 0 0.00 0.00 363 12 14 11.4 7.9400 32.7149 25.5142 59.3 6.98 303.8 0.280 0.532 118.3 11.6 0 1.16 0 17.3 0 0.34 0 0.09 0.83 0 -99.00 -99.00 362 11 13 16.5 7.9354 32.7146 25.5146 59.7 6.98 303.9 0.432 0.593 90.6 11.5 0 1.16 0 17.2 0 0.36 0 0.06 1.05 0 -99.00 -99.00 361 10 12 21.1 7.9173 32.7136 25.5164 59.7 6.98 303.9 0.595 0.559 70.0 11.5 0 1.16 0 17.1 0 0.35 0 0.07 0.97 0 0.00 6 7.91 6 360 9 11 25.8 7.7337 32.7133 25.5424 59.5 7.01 305.4 0.908 0.881 61.7 11.6 0 1.16 0 17.1 0 0.36 0 0.09 0.83 6 -99.00 -99.00 359 8 10 31.0 7.6423 32.7122 25.5545 60.6 7.04 306.5 1.049 1.127 66.6 11.6 0 1.16 0 16.9 0 0.42 0 0.12 0.86 0 -99.00 -99.00 358 7 9 41.8 7.3106 32.7170 25.6044 60.6 7.07 307.8 1.103 1.714 36.7 11.7 0 1.17 0 17.2 0 0.53 0 0.12 0.63 0 -99.00 -99.00 357 6 7 50.8 6.8653 32.7246 25.6705 62.8 7.09 308.5 0.696 2.098 22.9 12.4 0 1.21 0 17.8 0 0.55 0 0.26 0.39 0 -99.00 -99.00 356 5 5 76.2 6.3816 32.7487 25.7522 65.2 6.91 300.9 0.366 0.765 5.9 13.4 6 1.26 6 18.7 6 0.29 0 0.13 0.00 0 -99.00 -99.00 355 4 4 101.9 6.1672 33.0186 25.9922 66.3 6.09 264.8 0.171 0.373 1.8 17.6 0 1.47 0 24.4 0 0.14 0 0.07 0.00 0 0.00 0.00 354 3 3 176.1 5.6923 33.8381 26.6984 66.7 3.40 147.9 0.025 0.128 0.0 31.9 0 2.28 0 53.6 0 -99.00 0 -99.00 0.00 0 0.00 0.00 353 2 2 201.6 5.3026 33.8395 26.7461 66.7 3.06 133.0 0.025 0.139 0.0 34.1 0 2.43 0 60.0 0 -99.00 0 -99.00 0.00 0 0.00 0.00 352 1 1 302.3 4.5930 33.8944 26.8699 66.9 1.95 84.9 0.025 0.140 0.0 39.5 0 2.80 0 76.1 0 -99.00 0 -99.00 0.00 0 -99.00 -99.00
