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 !Samp Bo Bo Pressu Temperat Salinity Sigma-t: Trans Oxygen Oxyge Fluores Fluores Salinity Fl Oxygen: Oxyge Fl Nitra Fl Phosph Fl Silic Fl !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 !Numb ~u ~u vity: lved: solve CTD: CTD: ~o ed: ~ed:B ~o ~Nitr ~o Bottle ~o Bottl ~o !er mb en CTD CTD: d:CTD Seapoin Wetlabs tt Bottle: ottle tt ite:B tt tt e tt ! er ce Volume :Mass t le Volume :Mass le ottle le le le !---- -- -- ------ -------- -------- -------- ----- ------ ----- ------- ------- -------- -- ------- ----- -- ----- -- ------ -- ----- -- *END OF HEADER 627 24 24 6.0 6.3956 32.7084 25.7186 55.9 7.18 312.6 0.773 1.589 32.7121 0 7.236 315.0 2 15.5 0 1.44 0 27.4 0 626 23 23 11.9 6.3790 32.7085 25.7208 55.9 7.19 312.8 0.795 1.608 32.7149 0 7.241 315.2 0 15.7 0 1.44 0 27.3 0 625 22 22 25.7 6.3300 32.7088 25.7272 55.7 7.19 312.9 0.839 1.683 32.7130 0 7.193 313.1 2 15.9 0 1.43 0 27.3 0 624 21 21 51.7 6.0349 32.7127 25.7671 58.1 7.18 312.7 0.954 1.840 32.7179 0 7.205 313.6 0 16.1 0 1.46 0 27.4 0 623 20 20 76.5 5.1779 32.7185 25.8727 64.1 7.19 313.0 0.508 0.970 32.7226 0 7.205 313.6 0 16.9 0 1.53 0 28.8 0 622 19 19 101.3 4.7794 32.7431 25.9362 66.3 7.09 308.5 0.158 0.357 32.7500 0 7.086 308.4 0 17.4 0 1.57 0 28.6 0 621 18 18 126.3 4.0965 32.8476 26.0903 67.0 6.93 301.3 0.080 0.203 32.8525 0 6.922 301.2 6 20.0 0 1.70 0 32.3 0 620 17 17 151.9 4.5036 33.4490 26.5259 67.0 4.86 211.5 0.040 0.148 33.4393 0 4.900 213.1 0 27.9 0 2.13 0 46.7 0 619 16 16 176.2 4.3278 33.6700 26.7201 67.0 3.80 165.2 0.032 0.135 33.6724 0 3.800 165.2 0 32.4 6 2.42 6 58.1 6 618 15 15 201.2 4.0215 33.7467 26.8128 67.2 2.88 125.2 0.030 0.141 33.7459 0 2.894 125.8 0 36.7 0 2.70 0 70.3 0 617 14 14 251.2 3.9272 33.8278 26.8868 67.2 2.20 95.6 0.032 0.139 33.8266 0 2.196 95.5 0 38.9 0 2.86 0 79.8 0 616 13 13 302.1 3.8624 33.8971 26.9485 67.0 1.69 73.4 0.033 0.142 33.8997 0 1.671 72.6 0 41.0 0 2.97 0 88.0 0 615 12 12 402.2 3.8865 34.0361 27.0567 67.4 1.19 51.6 0.034 0.140 34.0363 0 1.172 50.9 0 42.1 0 3.06 0 100.0 0 614 11 11 601.7 3.6296 34.2059 27.2175 67.5 0.66 28.8 0.035 0.152 34.2060 0 0.652 28.3 0 43.4 0 3.17 0 118.2 0 613 10 10 801.3 3.2412 34.3049 27.3337 67.6 0.56 24.3 0.032 0.147 34.3049 0 0.538 23.4 0 43.8 0 3.22 0 132.3 0 612 9 9 1000.8 2.8921 34.3820 27.4272 67.7 0.51 22.3 0.030 0.144 34.3829 0 0.505 21.9 6 44.2 0 3.23 0 143.1 0 611 8 8 1250.9 2.5845 34.4474 27.5065 67.7 0.50 21.9 0.028 0.148 34.4487 0 0.497 21.6 0 44.5 0 3.25 0 154.3 0 610 7 7 1501.2 2.3245 34.5066 27.5758 67.8 0.53 23.0 0.026 0.146 34.5072 0 0.511 22.2 0 45.0 0 3.24 0 162.5 0 609 6 6 2002.3 1.9274 34.5880 27.6730 67.9 1.29 56.2 0.024 0.134 34.5888 0 1.278 55.5 0 43.0 0 3.10 0 171.1 0 608 5 5 2500.8 1.7091 34.6310 27.7243 67.9 1.97 85.6 0.022 0.121 34.6326 0 1.961 85.2 6 41.6 6 2.96 6 172.8 6 607 4 4 3001.2 1.5717 34.6584 27.7565 67.9 2.55 110.8 0.018 0.118 34.6598 0 2.544 110.5 0 39.9 0 2.84 0 172.0 0 606 3 3 3501.9 1.5115 34.6739 27.7734 67.9 2.94 127.7 0.016 0.116 34.6736 0 2.931 127.3 0 38.9 0 2.75 0 171.4 0 605 2 2 4002.3 1.5039 34.6826 27.7809 67.9 3.17 137.6 0.013 0.109 34.6830 6 3.152 136.9 0 38.6 0 2.71 0 171.5 0 604 1 1 4317.0 1.5202 34.6860 27.7824 67.3 3.23 140.4 0.015 0.132 34.6879 0 3.215 139.7 0 38.4 0 2.69 0 173.8 0
