Salinometers are standardized with IAPSO standard seawater. See file 2008-026_SAL.pdf for information on duplicates and note the warning below. 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 duplicates see file 2008-026_OXY.pdf. 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 2008-026_NUT.pdf. Chlorophyll samples were analyzed at sea using a Chemistry Turner Designs fluorometer which was calibrated in May 2007 using pure chlorophyll a. Chlorophyll precision was determined by analyzing replicate samples drawn from one Niskin. For details on duplicates see file 2008-026_CHL.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 2008-026_DMS_report.pdf and for duplicates see 2008-026_DMS.pdf. DMSP-D and DMSP-T: Contamination in the blanks resulted in all data being discarded. For details on analysis see document 2008-026_DMS_report.pdf. Dissolved inorganic carbon (DIC) was determined using coulometric analysis. Total alkalinity (Alk) was determined by potentiometric titration. pH on the total hydrogren 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 2008-026_DIC.pdf, 2008-026_ALK.pdf, and 2008-026_pH.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 ~2 weeks 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, Chlide-a and Me-chlide. References: 1. Carpenter, J.H. 1965.

Data Processing Notes: ---------------------- The salinity analyses done on a Portasal salinometer at sea are considered unreliable. Many duplicate samples were run using an Autosal at IOS and the Portasal. The results showed that the Portasal read much lower than the Autosal for those samples analyzed on the Portasal on June 5th. For other days the Portasal was low by an average of 0.0016 but there was a lot of noise in the comparison with many values within 0.001 of the Autosal, while others looked unstable. Autosal values have been selected for Salinity:Bottle where possible. Where there are no Autosal values, the Portasal values were used, but were all flagged "3", except for those from June 5th which have been flagged "4". For details on the processing see processing report: 2008-026-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-- !Samp Bo Pressu Temperat Salinity Sigma-t: Trans Oxygen Oxyge Fluores !le_ tt re:CTD ure:CTD :CTD CTD missi :Disso n:Dis cence: !Numb ~u vity: lved: solve CTD: !er mb CTD CTD: d:CTD Seapoin ! er Volume :Mass t !---- -- ------ -------- -------- -------- ----- ------ ----- ------- *END OF HEADER 329 24 5.2 8.2236 32.5179 25.3183 54.1 7.18 312.6 0.438 328 23 5.2 8.2218 32.5183 25.3189 53.9 7.18 312.4 0.415 327 22 5.3 8.2232 32.5181 25.3185 54.3 7.18 312.8 0.419 326 21 5.2 8.2233 32.5183 25.3186 54.2 7.18 312.8 0.411 325 20 5.2 8.2222 32.5184 25.3189 54.3 7.18 312.4 0.395 324 19 6.9 8.2210 32.5188 25.3194 54.0 7.16 311.9 0.415 323 18 7.1 8.2200 32.5188 25.3195 54.3 7.17 312.1 0.415 322 17 6.8 8.2219 32.5186 25.3191 54.4 7.17 312.1 0.406 321 16 6.8 8.2242 32.5185 25.3187 54.1 7.17 312.3 0.404 320 15 6.7 8.2220 32.5185 25.3190 54.1 7.17 312.4 0.408 319 14 6.4 8.2206 32.5189 25.3195 54.3 7.16 311.9 0.411 318 13 5.9 8.2174 32.5187 25.3198 54.5 7.16 311.7 0.392 317 12 44.6 7.5872 32.5647 25.4463 52.0 7.28 316.9 1.248 316 11 44.6 7.5811 32.5649 25.4474 52.2 7.28 316.9 1.361 315 10 44.1 7.5979 32.5649 25.4450 52.2 7.28 316.7 1.242 314 9 44.0 7.6011 32.5649 25.4446 52.3 7.27 316.5 1.208 313 8 44.1 7.5922 32.5646 25.4456 52.3 7.26 316.3 1.191 312 7 44.0 7.5912 32.5645 25.4456 52.2 7.27 316.5 1.253 311 6 44.3 7.5865 32.5643 25.4461 52.2 7.26 316.3 1.257 310 5 44.4 7.5848 32.5642 25.4463 52.1 7.27 316.4 1.240 309 4 44.4 7.5847 32.5640 25.4461 52.2 7.26 316.2 1.232 308 3 45.2 7.5781 32.5640 25.4471 52.3 7.26 316.2 1.195 307 2 44.6 7.5879 32.5638 25.4455 52.2 7.26 316.1 1.193 306 1 44.7 7.5868 32.5636 25.4455 51.8 7.26 316.2 1.217
