Sample Number 20: Dimethylsulfoniopropionate_Dissolved:Bottle and Dimethylsulfoniopropionate_Total:Bottle - suspect instrument problems. 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 --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 27 14 13 6.3 10.4311 31.7758 24.3896 51.8 6.91 301.2 0.338 0.880 205.8 -99.0 0 -99.00 0 -99.0 0 0.66 6 0.28 -99.00 0 -99.00 0 -99.00 0 26 13 10 16.4 9.2635 32.1336 24.8592 49.8 6.65 289.6 0.465 3.762 40.7 -99.0 0 -99.00 0 -99.0 0 2.52 6 0.74 -99.00 0 -99.00 0 -99.00 0 25 12 6 31.1 8.1280 32.6260 25.4171 49.9 6.14 267.3 0.475 0.991 6.7 -99.0 0 -99.00 0 -99.0 0 0.63 6 0.40 -99.00 0 -99.00 0 -99.00 0 24 11 14 3.0 10.6978 31.7420 24.3179 45.5 6.81 296.9 0.931 0.659 345.3 0.2 0 0.30 0 2.7 0 0.55 0 0.21 2.83 0 0.00 0 127.68 0 23 10 12 6.4 10.4182 31.7770 24.3927 39.5 6.92 301.6 2.168 0.901 197.5 0.2 0 0.30 0 2.6 0 0.56 0 0.22 2.19 0 3.07 0 0.00 0 22 9 11 10.8 9.9367 31.8662 24.5423 39.7 7.08 308.4 2.221 1.679 100.6 0.2 0 0.32 0 2.8 0 1.06 0 0.55 1.60 0 -99.00 0 -99.00 0 21 8 9 16.5 9.2531 32.1374 24.8638 50.1 6.63 288.9 1.490 3.755 39.9 1.8 0 0.56 0 5.5 0 2.61 0 0.56 1.81 0 -99.00 0 -99.00 0 20 7 8 21.3 8.5927 32.4593 25.2174 55.9 6.30 274.6 0.793 2.726 19.2 6.2 0 0.87 0 10.0 0 2.07 0 0.83 0.96 6 7.07 3 51.03 3 19 6 7 26.4 8.2524 32.5917 25.3719 62.0 6.18 268.9 0.561 1.623 10.4 9.0 0 1.03 0 13.0 0 1.06 0 0.53 0.56 0 -99.00 0 -99.00 0 18 5 5 31.1 8.1206 32.6294 25.4208 62.0 6.13 267.1 0.557 0.973 6.7 10.3 0 1.09 0 14.4 0 0.59 0 0.37 0.00 0 -99.00 0 -99.00 0 17 4 4 41.0 7.9021 32.7602 25.5552 64.2 5.78 251.4 0.287 0.603 3.2 13.4 0 1.26 0 17.2 0 0.43 0 0.23 0.43 0 -99.00 0 -99.00 0 16 3 3 51.2 7.8602 32.8964 25.6682 64.9 5.27 229.4 0.130 0.301 1.6 15.8 6 1.40 6 19.8 6 0.19 0 0.22 0.38 0 -99.00 0 -99.00 0 15 2 2 76.8 7.7627 33.3157 26.0115 64.0 3.87 168.3 0.088 0.261 0.4 23.9 0 1.89 0 29.7 0 0.13 0 0.28 0.00 0 -99.00 0 -99.00 0 14 1 1 101.2 7.1333 33.7631 26.4520 57.5 2.25 98.0 0.065 0.228 0.1 31.5 0 2.48 0 47.0 0 0.09 0 0.39 0.00 0 0.00 0 -99.00 5
