Chlorophyll precision was determined by analyzing replicate samples drawn from one Niskin. For details see file 2008-01_CHL.pdf Oxygen samples were analyzed on an automated Winkler titration system following the procedures of Carpenter (1965). Samples were analyzed at sea using an automated titration system consisting of a Brinkman Dosimat (model 665) and a PC 900 Colorimeter. For details on precision see file 2008-01_OXY.pdf. Salinity samples were collected in glass bottles and analyzed on a Guildline model 8400B Autosal or a Guildline Portasal 8410A. Salinometers are standardized with IAPSO standard seawater. See file 2008-01_SAL.pdf for information on precision. Nutrient samples were collected in plastic tubes and analyzed fresh at sea using a Technicon AAII autoanalyzer following methods described in Barwell-Clarke and Whitney (1996). For details on nutrient duplicates and precision see file 2008-01_NUT.pdf. 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 2008-01_DMS_report.pdf. For details on duplicates see file 2008-01_DMS.pdf. Dissolved inorganic carbon (DIC) was determined using coulometric analysis. Total alkalinity (Alk) was determined by potentiometric titration. pH on the total hydrogen ion concentration scale was determined photometrically and is reported at 25C and surface pressure. For duplicates and precision of DIC, ALK and pH samples see files 2008-01_DIC.pdf, 2008-01_ALK.pdf, and 2008-01_pH.pdf respectively. References: 1. Carpenter, J.H. 1965.

While the CTD data corresponds to the level at which the bottle was fired, in many cases the bottle closed earlier. Notes in the headers of individual files indicate the probable level at which bottles closed, where evidence exists to make that estimate. ********************************************************************************** For details on the processing see processing report: 2008-01-proc.pdf $REMARKS Data quality is expressed with the following flags ---------------------------------------------------------------------------- 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 !Samp Bo Pressu Temperat Salinity Sigma-t: Trans Oxygen Oxyge Fluores PAR: Nitra Fl Phosph Fl Silic Fl Chloro Fl Dimeth Fl !le_ tt re:CTD ure:CTD : CTD missi :Disso n:Dis cence: CTD te_pl ag ate: ag ate: ag phyll: ag yl_ ag !Numb ~u Practica vity: lved: solve CTD: ~Nitr ~o Bottle ~o Bottl ~o Extrac ~o Sulphi ~o !er mb l:CTD CTD CTD: d:CTD Seapoin ite:B tt tt e tt ted: tt de: tt ! er Volume :Mass t ottle le le le Bottle le Bottle le !---- -- ------ -------- -------- -------- ----- ------ ----- ------- ------ ----- -- ------ -- ----- -- ------ -- ------ -- *END OF HEADER 44 18 1.9 7.8121 32.4336 25.3116 50.5 6.86 298.7 0.809 0.7 -99.0 -99.00 -99.0 0.75 0.63 43 17 5.6 7.8103 32.4337 25.3120 51.6 6.86 298.7 0.813 0.1 -99.0 -99.00 -99.0 -99.00 -99.00 42 16 6.1 7.8101 32.4336 25.3119 55.0 6.86 298.7 0.827 0.1 -99.0 -99.00 -99.0 -99.00 -99.00 41 15 5.4 7.8109 32.4336 25.3118 53.8 6.86 298.8 0.811 0.1 -99.0 -99.00 -99.0 0.83 0.54 40 14 11.3 7.8077 32.4337 25.3123 55.6 6.86 298.6 0.808 0.0 -99.0 -99.00 -99.0 0.79 0.52 39 13 16.9 7.8127 32.4337 25.3116 55.5 6.86 298.7 0.810 0.0 10.0 6 1.11 6 12.8 6 0.78 6 0.62 38 12 21.5 7.8161 32.4336 25.3111 55.5 6.85 298.4 0.830 0.0 10.0 1.10 13.0 0.79 0.43 6 37 11 26.4 7.8165 32.4337 25.3111 55.6 6.85 298.3 0.816 0.0 10.1 1.10 12.9 0.73 0.49 36 10 30.5 7.8164 32.4337 25.3111 55.5 6.85 298.3 0.820 0.0 10.0 1.10 13.1 0.74 0.56 35 9 41.0 7.8185 32.4346 25.3115 55.6 6.84 297.7 0.814 0.0 10.0 1.09 12.9 0.68 0.38 34 8 50.8 7.8216 32.4353 25.3116 55.7 6.81 296.7 0.809 0.0 10.0 1.09 12.9 0.72 0.95 33 7 74.2 8.0522 33.1772 25.8607 59.2 4.36 189.6 0.168 0.0 21.9 1.79 26.6 0.05 0.00 32 6 99.4 7.8556 33.5313 26.1675 59.3 3.34 145.5 0.131 0.0 27.2 2.09 34.0 0.02 0.00 31 5 151.8 7.5801 33.8324 26.4438 59.4 2.44 106.2 0.122 0.0 -99.0 -99.00 -99.0 -99.00 -99.00 30 4 175.6 7.3578 33.8779 26.5111 59.6 2.36 102.4 0.122 0.0 31.9 2.38 44.4 -99.00 -99.00 29 3 200.2 7.1510 33.9249 26.5770 60.2 2.17 94.5 0.122 0.0 32.8 2.43 47.4 -99.00 0.00 28 2 250.3 6.7514 33.9658 26.6637 59.6 1.80 78.1 0.124 0.0 -99.0 -99.00 -99.0 -99.00 -99.00 27 1 302.6 6.3410 34.0102 26.7528 60.1 1.45 63.2 0.124 0.0 37.0 2.72 61.4 -99.00 -99.00
