Samples Number 370, 371, 375 to 377, 381, 382: Phosphate:Bottle - rerun. Analysis methods: ----------------- Salinity samples were collected in 200 ml type ll glass bottles with disposable plastic inserts 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 1.6 months after collection. The duplicate analysis is in file 2012-13_SAL.pdf. Oxygen samples were analyzed at sea on an automated Winkler titration system (Brinkmann Dosimat model 665 for titrations, Dosimat model 865 for dispensing standards 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 on duplicate analysis see file 2012-13_OXY.pdf. Nutrient samples were collected in plastic tubes and quick frozen in aluminum blocks stored in -20 freezer. One set of samples from 400 dbar and deeper (to be used for silicate analysis) was collected and stored at 4C in the dark. All samples were returned to IOS for analysis. They were analyzed using an Astoria analyzer following methods described in Barwell-Clarke and Whitney (1996). For precision and duplicate details see file 2012-13_NUT.pdf. 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 -80C 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 2012-13_CHL.pdf. Phaeopigment data are provided for information only and no quality flags are assigned to them. Note: The variability between replicates was higher than usual and the values are lower than they typically are in comparison to HPLC Chlorophyll:Extracted. The minimum detectable level for DMS is 0.10 nM, so “0” values should be interpreted as <0.10. The minimum detectable level for DMSP in this file is 0.1 nM, so “0” values should be interpreted as <0.10. For details on the collection and analysis of the DMS and DMSP data see file 2012-13_DMS_report.pdf and for DMS duplicates see 2012-13_DMS.pdf. References: 1.

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) with a modification allowing a small offset.

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 !Samp Bo Bo Pressu Temperat Salinity Sigma-t: Trans Oxygen Oxyge 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: :Bottle ag Dissolv n:Dis ag te_pl ag ate: ag ate: ag !Numb ~u ~u vity: lved: solve CTD: ~o ed: ~ed:B ~o ~Nitr ~o Bottle ~o Bottl ~o !er mb en CTD CTD: d:CTD Seapoin 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 393 24 24 5.4 13.8228 32.5148 24.3298 53.3 6.25 272.2 1.120 -99.0000 0 6.256 272.7 6 11.6 0 1.15 0 18.4 0 392 23 23 10.3 13.8215 32.5143 24.3297 53.4 6.25 272.2 1.113 -99.0000 0 6.264 273.0 0 11.6 0 1.16 0 18.4 0 391 22 22 25.5 12.6291 32.5175 24.5686 56.4 6.43 280.0 1.241 -99.0000 0 6.458 281.4 0 11.8 0 1.19 0 19.0 0 390 21 21 50.9 7.2087 32.6599 25.5735 59.7 7.25 315.6 1.338 -99.0000 0 7.220 314.3 0 13.6 0 1.15 0 23.3 0 389 20 20 75.6 5.3746 32.7188 25.8505 64.5 7.05 306.8 0.588 -99.0000 0 7.029 305.9 0 16.8 6 1.49 6 26.7 6 388 19 19 101.7 4.6198 32.8100 26.0064 66.3 6.78 295.1 0.238 -99.0000 0 6.749 301.1 6 19.0 0 1.61 0 29.5 0 387 18 18 124.9 5.2059 33.3359 26.3584 66.8 5.11 222.4 0.086 -99.0000 0 5.131 223.2 0 25.0 0 1.91 0 38.9 0 386 17 17 150.8 5.1314 33.7031 26.6579 66.9 3.85 167.4 0.073 -99.0000 0 3.919 170.4 0 30.2 0 2.21 0 51.0 0 385 16 16 175.4 4.7809 33.7650 26.7465 66.9 3.25 141.5 0.060 -99.0000 0 3.249 141.3 0 33.6 0 2.30 0 61.1 0 384 15 15 200.3 4.5144 33.7943 26.7989 67.0 2.83 122.9 0.060 -99.0000 0 2.829 123.0 0 35.7 0 2.57 0 67.5 0 383 14 14 250.5 4.4137 33.8719 26.8714 67.2 2.13 92.6 0.058 -99.0000 0 2.127 92.5 0 38.2 0 2.75 0 76.1 0 382 13 13 299.5 4.3338 33.9311 26.9269 67.2 1.74 75.7 0.060 -99.0000 0 1.728 75.1 0 39.9 0 2.94 3 83.2 0 381 12 12 400.5 4.1767 34.0315 27.0232 67.3 1.27 55.1 0.060 -99.0000 0 1.270 55.2 0 41.3 0 3.05 3 94.2 0 380 11 11 601.6 3.7120 34.1888 27.1957 67.4 0.60 26.2 0.062 -99.0000 0 0.592 25.7 0 43.7 6 3.13 6 116.6 6 379 10 10 800.5 3.2647 34.2996 27.3272 67.6 0.43 18.9 0.063 -99.0000 0 0.422 18.3 0 44.9 0 3.24 0 133.4 0 378 9 9 999.2 2.9317 34.3760 27.4189 67.6 0.36 15.5 0.063 34.3758 6 0.349 15.2 6 45.2 0 3.27 0 145.0 0 377 8 8 1250.7 2.5766 34.4535 27.5121 67.6 0.36 15.6 0.062 34.4539 0 0.355 15.4 0 45.6 0 3.31 3 157.3 0 376 7 7 1500.5 2.3179 34.5055 27.5755 67.8 0.57 24.6 0.064 34.5051 0 0.571 24.8 0 45.6 0 3.35 3 165.1 0 375 6 6 2001.2 1.9189 34.5878 27.6735 67.9 1.31 57.1 0.060 34.5873 0 1.309 56.9 0 43.1 0 3.13 3 172.8 0 374 5 5 2500.3 1.6985 34.6318 27.7257 67.9 1.98 85.9 0.055 34.6311 0 1.962 85.2 0 41.6 6 2.94 6 174.1 6 373 4 4 2999.8 1.5586 34.6584 27.7575 67.9 2.57 111.5 0.052 34.6572 6 2.562 111.3 0 39.8 0 2.81 0 172.6 0 372 3 3 3000.5 1.5587 34.6583 27.7574 67.9 2.56 111.4 0.051 34.6580 0 2.570 111.6 0 39.8 0 2.80 0 173.0 0 371 2 2 3500.5 1.5147 34.6722 27.7718 67.9 2.90 125.9 0.051 34.6716 0 2.888 125.5 6 38.7 0 2.81 3 173.1 0 370 1 1 4025.3 1.5386 34.6781 27.7747 67.2 3.01 130.8 0.051 -99.0000 0 2.990 129.9 2 38.3 0 2.78 3 175.6 0
