Analysis methods: ----------------- Salinity samples were collected in 200 ml type ll glass bottles with reusable silicone inserts supplied by Xiamen Cuten Accessories Industry Limited and screw caps supplied by Ocean Scientific International Limited. 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-- !Samp Bo Bo Pressu Temperat Salinity Sigma-t: Trans Oxygen Oxyge Fluores Fluores Salinity Fl Oxygen: Oxyge Fl Nitra Fl Phosph Fl Silic Fl Chloro Fl Phaeo- !le_ tt tt re:CTD ure:CTD :CTD CTD missi :Disso n:Dis cence: cence: :Bottle ag Dissolv n:Dis ag te_pl ag ate: ag ate: ag phyll: ag Pigmen !Numb ~u ~u vity: lved: solve CTD: CTD: ~o ed: ~ed:B ~o ~Nitr ~o Bottle ~o Bottl ~o Extrac ~o t:Extr !er mb en CTD CTD: d:CTD Seapoin Wetlabs tt Bottle: ottle tt ite:B tt tt e tt ted: tt acted: ! er ce Volume :Mass t le Volume :Mass le ottle le le le Bottle le Bottle !---- -- -- ------ -------- -------- -------- ----- ------ ----- ------- ------- -------- -- ------- ----- -- ----- -- ------ -- ----- -- ------ -- ------ *END OF HEADER 207 22 22 6.8 10.5339 31.9881 24.5376 55.4 6.74 293.7 0.823 1.452 -99.0000 0 -99.000 -99.0 0 -99.0 0 -99.00 0 -99.0 0 0.55 6 0.16 206 21 19 21.8 9.8072 32.5248 25.0775 55.4 6.81 296.6 0.835 1.395 -99.0000 0 -99.000 -99.0 0 -99.0 0 -99.00 0 -99.0 0 0.37 6 0.08 205 20 17 50.6 7.3079 32.6657 25.5645 55.1 6.92 301.2 0.827 1.651 -99.0000 0 -99.000 -99.0 0 -99.0 0 -99.00 0 -99.0 0 0.35 6 0.16 204 19 21 7.1 10.5354 31.9884 24.5375 59.2 6.73 293.3 0.885 1.318 31.9919 0 6.734 293.4 0 1.3 0 0.50 0 7.1 0 0.57 0 0.14 203 18 20 11.1 10.5336 31.9891 24.5384 60.3 6.74 293.8 1.104 1.349 -99.0000 0 6.743 293.8 0 1.4 0 0.50 0 7.1 0 0.57 0 0.15 202 17 18 28.0 9.2111 32.6323 25.2574 63.1 6.95 302.6 1.012 1.751 -99.0000 0 6.922 301.4 0 6.1 0 0.85 0 11.5 0 0.16 3 0.05 201 16 16 50.6 7.3162 32.6656 25.5632 63.1 6.92 301.4 1.003 1.643 -99.0000 0 6.902 300.5 0 10.0 0 1.08 0 15.7 0 0.34 0 0.17 200 15 15 76.2 6.9155 32.7099 25.6522 65.5 6.72 292.3 0.336 0.621 -99.0000 0 6.706 291.9 6 11.3 0 1.17 0 16.6 0 0.23 0 0.14 199 14 14 101.4 7.3425 33.2752 26.0391 66.3 4.96 215.9 0.099 0.241 -99.0000 0 5.170 225.0 0 18.7 0 1.53 0 23.5 0 0.09 0 0.07 198 13 13 127.3 7.4216 33.6524 26.3247 66.6 3.82 166.2 0.045 0.165 -99.0000 0 3.828 166.5 0 25.5 6 1.92 6 31.7 6 -99.00 0 -99.00 197 12 12 151.7 7.2136 33.7973 26.4678 66.7 3.46 150.5 0.030 0.145 -99.0000 0 3.489 151.8 0 27.7 0 2.04 0 36.2 0 -99.00 0 -99.00 196 11 11 176.4 6.9360 33.8662 26.5602 66.8 3.11 135.1 0.027 0.157 -99.0000 0 3.120 135.7 0 30.0 0 2.18 0 41.2 0 -99.00 0 -99.00 195 10 10 201.9 6.7443 33.8839 26.6001 66.9 3.03 131.9 0.026 0.148 -99.0000 0 3.036 132.0 0 30.8 0 2.23 0 43.8 0 -99.00 0 -99.00 194 9 9 252.0 6.0859 33.9095 26.7060 66.7 2.51 109.3 0.024 0.139 -99.0000 0 2.538 110.4 0 33.9 0 2.46 0 53.3 0 -99.00 0 -99.00 193 8 8 300.9 5.6807 33.9531 26.7908 66.7 1.78 77.5 0.023 0.144 -99.0000 0 1.816 79.0 0 37.8 0 2.73 0 63.3 0 -99.00 0 -99.00 192 7 7 402.2 5.1359 34.0190 26.9077 67.3 1.13 49.2 0.023 0.142 -99.0000 0 1.151 50.0 0 41.2 0 2.98 0 76.7 0 -99.00 0 -99.00 191 6 6 601.8 4.4675 34.1920 27.1198 67.4 0.35 15.3 0.024 0.149 -99.0000 0 0.355 15.4 0 44.6 0 3.28 0 101.3 0 -99.00 0 -99.00 190 5 5 801.1 3.8101 34.2981 27.2729 67.6 0.23 10.2 0.026 0.145 34.2988 0 0.234 10.2 0 46.1 0 3.35 0 121.6 0 -99.00 0 -99.00 189 4 4 1001.2 3.4026 34.3866 27.3835 67.6 0.25 10.7 0.024 0.147 34.3878 6 0.257 11.2 6 46.2 0 3.37 0 135.7 0 -99.00 0 -99.00 188 3 3 1251.8 2.9252 34.4697 27.4943 67.6 0.42 18.3 0.025 0.152 34.4711 0 0.460 20.0 0 45.9 6 3.34 6 151.1 6 -99.00 0 -99.00 187 2 2 1500.7 2.4678 34.5127 27.5687 67.6 0.66 28.6 0.024 0.143 -99.0000 0 0.693 30.1 0 45.4 0 3.27 0 165.0 0 -99.00 0 -99.00 186 1 1 2002.3 1.9172 34.5957 27.6800 67.9 1.43 61.9 0.021 0.129 34.5973 6 1.462 63.5 6 43.2 0 3.09 0 178.0 0 -99.00 0 -99.00
