Oxygen samples are analyzed on an automated Winkler titration system following the procedures of Carpenter (1965). A Brinkmann model 665 Dosimat and model PC910 Colorimeter is controlled by Visual-Basic program to titrate the oxygen samples. Nutrient samples were analyzed fresh at sea using a Technicon AAII autoanalyzer following methods described in Barwell-Clarke and Whitney (1996). For details on duplicate samples and precision see file 2007-01_NUT.pdf. Chlorophyll samples are collected in calibrated polycarbonate bottles (~330ml), then filtered onto 25mm MFS GF/75 filters at <70mmHg vacuum. The filters are placed in glass scintillation vials and immediately frozen at -20ºC until analysis. The chlorophyll is extracted in 10 ml of 90% acetone for 24h at -20ºC, then brought to room temperature and the extract is decanted and measured using a Turner Designs Model 10 fluorometer, which has been calibrated with solutions of commercially prepared chlorophyll. 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 2007-01_DMS_Report.pdf. See file 2007-01_DMS_duplicates.pdf for duplicates analysis. Dissolved inorganic carbon (DIC) was determined using coulometric analysis. Total alkalinity (Alk) was determined by potentiometric titration. For duplicates and precision of DIC and ALK samples see files 2007-01_DIC.pdf and 2007-01_ALK.pdf respectively. References: 1.

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 !Samp Bo Pressu Temperat Salinity Sigma-t: Trans Oxygen Oxyge Fluores Salinity Fl Nitra Fl Phosph Fl Silic Fl Chloro Fl !le_ tt re:CTD ure:CTD :CTD CTD missi :Disso n:Dis cence: :Bottle ag te_pl ag ate: ag ate: ag phyll: ag !Numb ~u vity: lved: solve CTD ~o ~Nitr ~o Bottle ~o Bottl ~o Extrac ~o !er mb CTD CTD: d:CTD tt ite:B tt tt e tt ted: tt ! er Volume :Mass le ottle le le le Bottle le !---- -- ------ -------- -------- -------- ----- ------ ----- ------- -------- -- ----- -- ------ -- ----- -- ------ -- *END OF HEADER 80 1 4.9 8.4059 32.4178 25.2129 51.4 6.68 290.8 0.733 32.4182 0 8.6 0 1.00 0 9.8 0 0.61 0
