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 116 24 17 42.2 8.6527 32.5329 25.2660 61.7 6.12 266.6 0.328 0.533 0.6 115 23 10 126.3 7.8389 33.5058 26.1499 61.8 3.65 158.7 0.335 0.269 0.0 114 22 24 2.2 11.0558 31.7485 24.2610 61.6 6.74 293.6 0.316 0.589 21.9 113 21 23 10.9 11.0425 31.7642 24.2755 62.9 6.75 294.0 0.255 0.571 6.0 112 20 22 10.9 11.0398 31.7648 24.2764 63.2 6.74 293.9 0.271 0.533 6.0 111 19 21 21.7 10.3600 31.8049 24.4243 62.9 6.84 298.3 0.435 0.525 2.5 110 18 20 21.6 10.3587 31.8027 24.4228 62.8 6.85 298.4 0.400 0.525 2.6 109 17 19 31.7 8.9882 32.4015 25.1117 63.9 6.22 270.8 0.299 0.772 1.2 108 16 18 31.4 8.9763 32.4071 25.1179 64.4 6.22 270.9 0.299 0.700 1.2 107 15 16 51.3 8.5598 32.5642 25.3046 64.2 6.19 269.6 0.302 0.512 0.4 106 14 15 51.4 8.5607 32.5647 25.3048 64.4 6.18 269.3 0.209 0.512 0.4 105 13 14 76.3 8.3091 32.7171 25.4619 64.0 5.74 249.8 0.245 0.441 0.1 104 12 13 76.2 8.3096 32.7175 25.4621 63.4 5.74 249.8 0.154 0.377 0.1 103 11 12 100.4 8.1165 33.0948 25.7866 63.3 4.54 197.5 0.171 0.368 0.0 102 10 11 100.3 8.1167 33.0939 25.7859 65.0 4.54 197.7 0.129 0.344 0.0 101 9 9 151.6 7.4553 33.7579 26.4030 65.8 3.33 144.8 0.055 0.181 0.0 100 8 8 151.6 7.4557 33.7577 26.4028 65.6 3.33 144.9 0.052 0.184 0.0 99 7 7 201.9 7.0116 33.8884 26.5674 65.9 2.64 115.0 0.031 0.150 0.0 98 6 6 202.4 7.0143 33.8894 26.5678 65.8 2.64 114.9 0.032 0.161 0.0 97 5 5 301.7 5.8628 34.0051 26.8095 66.0 1.34 58.2 0.033 0.159 0.0 96 4 4 301.3 5.8618 34.0049 26.8094 65.9 1.34 58.2 0.031 0.144 0.0 95 3 3 400.6 5.3566 34.0830 26.9325 66.9 0.78 34.1 0.029 0.147 0.0 94 2 2 501.4 4.9594 34.1516 27.0331 66.9 0.49 21.1 0.027 0.146 0.0 93 1 1 501.1 4.9593 34.1516 27.0331 67.0 0.49 21.1 0.028 0.159 0.0
