Oxygen samples were analyzed at sea on an automated Winkler titration system following the procedures of Carpenter (1965). A Brinkmann model 665 Dosimat and model PC910 Colorimeter was controlled by Visual-Basic program to titrate the oxygen samples. Nutrient samples were analysed fresh at sea using the new Astoria system following methods described in Barwell-Clarke and Whitney (1996). For duplicates and precision see file 2007-013_NUT.pdf. Chlorophyll samples were collected in calibrated polycarbonate bottles (~330ml), then filtered onto 25mm MFS GF/75 filters at <70mmHg vacuum. The filters were placed in glass scintillation vials and immediately frozen at -20°C until analysis. The chlorophyll was extracted in 10 ml of 90% acetone for 24h at -20ºC, then brought to room temperature and the extract was decanted and measured using a Turner Designs Model 10 fluorometer, which had been calibrated with solutions of commercially prepared chlorophyll. Chlorophyll samples were analyzed on board ship. 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 2007-013_DMS_report.doc. For details on duplicates see file 2007-013_DMS.pdf. 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 2007-013_DIC.pdf and 2007-013_ALK.pdf respectively. HPLC samples were filtered onto 25mm GF/F filters and stored at -80C prior to analysis. Samples were extracted in 95% methanol at -20C for 24 hours and analyzed on a WATERS 2695 HPLC separations system as detailed in Nemcek and Pena, 2014. Analysis was performed ~6-24 months after collection. The average of two samples is reported. Variability is assessed as the %CV (std dev/mean*100) for duplicate pairs. All pigments below the limit of detection (LOD) are assigned a zero value. TChl-a is the sum of Chl-a, DVchl-a and Chlide-a. References: 1. Carpenter, J.H. 1965.

Data Processing Notes: ---------------------- For details on the processing see processing report: 2007-013-proc.pdf $REMARKS Quality flags have the following significance: ---------------------------------------------------------------------------------- 0 = Acceptable measurement with no header comment. 1 = Sample for this measurement was collected but not analyzed. Sample lost. 2 = Acceptable measurement with header comment. 3 = Questionable measurement (probably good). 4 = Poor measurement (probably bad). 5 = Measurement not reported (bad). 6 = Mean of replicate measurements. 7 = Manual chromatographic peak measurement. 8 = Irregular digital chromatographic peak integration. 9 = Sample was planned for this measurement from this bottle but was not collected. ----------------------------------------------------------------------------------- $END !-1-- 2- --3--- ---4---- ---5---- ---6---- --7-- --8--- --9-- ---10-- --11-- !Samp Bo Pressu Temperat Salinity Sigma-t: Trans Oxygen Oxyge Fluores PAR: !le_ tt re:CTD ure:CTD :CTD CTD missi :Disso n:Dis cence: CTD !Numb ~u vity: lved: solve CTD: !er mb CTD CTD: d:CTD Seapoin ! er Volume :Mass t !---- -- ------ -------- -------- -------- ----- ------ ----- ------- ------ *END OF HEADER 477 8 32.4 7.3647 32.5394 25.4573 53.7 7.21 314.0 0.818 1.8 476 7 41.3 7.3568 32.5390 25.4581 53.7 7.20 313.5 0.837 1.0 475 6 51.9 7.3097 32.5395 25.4650 54.1 7.21 313.7 0.878 0.5 474 5 60.6 6.0340 32.5944 25.6737 56.9 7.30 318.0 0.701 0.3 473 4 71.5 5.5373 32.6338 25.7643 57.8 7.24 315.3 0.671 0.1 472 3 80.9 5.3970 32.6357 25.7821 58.1 7.19 312.8 0.574 0.1 471 2 91.4 5.1810 32.6241 25.7975 59.0 7.19 312.9 0.372 0.0 470 1 101.7 5.1002 32.6653 25.8392 59.5 7.03 305.8 0.241 0.0
