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-- !Samp Bo Pressu Temperat Salinity Sigma-t: Trans Oxygen Oxyge Fluores !le_ tt re:CTD ure:CTD : CTD missi :Disso n:Dis cence: !Numb ~u Practica vity: lved: solve CTD: !er mb l:CTD CTD CTD: d:CTD Seapoin ! er Volume :Mass t !---- -- ------ -------- -------- -------- ----- ------ ----- ------- *END OF HEADER 60 16 11.7 7.7557 32.4159 25.3057 55.3 6.85 298.3 0.831 59 15 11.0 7.7558 32.4158 25.3056 55.2 6.85 298.4 0.840 58 14 11.6 7.7554 32.4159 25.3058 55.2 6.86 298.5 0.831 57 13 11.4 7.7560 32.4159 25.3057 55.2 6.85 298.3 0.831 56 12 503.9 5.1310 34.1147 26.9841 60.6 0.67 29.0 0.124 55 11 502.4 5.1317 34.1143 26.9837 60.6 0.67 29.0 0.124 54 10 503.5 5.1294 34.1148 26.9843 60.6 0.67 29.0 0.125 53 9 502.6 5.1307 34.1146 26.9840 60.6 0.67 29.0 0.126 52 8 1003.1 3.5521 34.3881 27.3702 60.5 0.29 12.5 0.121 51 7 1001.9 3.5530 34.3879 27.3700 60.5 0.29 12.5 0.122 50 6 1001.0 3.5534 34.3878 27.3699 60.5 0.29 12.5 0.122 49 5 1003.9 3.5522 34.3881 27.3702 60.5 0.29 12.5 0.121 48 4 1308.8 2.9702 34.4689 27.4896 60.1 0.49 21.1 0.120 47 3 1308.6 2.9708 34.4687 27.4894 60.1 0.49 21.1 0.123 46 2 1308.8 2.9702 34.4688 27.4895 60.1 0.49 21.1 0.121 45 1 1308.3 2.9691 34.4689 27.4897 60.1 0.49 21.1 0.122
