Analysis methods: ----------------- Salinity samples were collected in glass bottles and analyzed on a Guildline model 8400B Autosal at IOS or a Guildline Portasal 8410A at sea. Salinometers are standardized with IAPSO standard seawater. See file 2008-027_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 910 Colorimeter. For details on duplicates see file 2008-027_OXY.pdf. Nutrient samples were analyzed from frozen samples using an Astoria system following methods described in Barwell-Clarke and Whitney (1996). For details on nutrient duplicates and precision see file 2008-027_NUT.pdf. Chlorophyll samples were analyzed at sea using a Chemistry Turner 10 AU fluorometer which was calibrated on April 23, 2008 using pure chlorophyll a. Chlorophyll precision was determined by analyzing replicate samples drawn from one Niskin. For details on duplicates see file 2008-027_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 2008-027_DMS_report.pdf and for duplicates see 2008-027_DMS.pdf. DMSP-D and DMSP-T: Contamination in the blanks resulted in all data being discarded. For details on analysis see document 2008-027_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 2008-027_DIC.pdf, 2008-027_ALK.pdf, and 2008-027_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 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, Chlide-a and Me-chlide. References: 1. Carpenter, J.H. 1965.

Data Processing Notes: ---------------------- WARNING: There were problems with both salinometers. Variations in the performance of the Portasal were fairly random from day to day, while the Autosal results were fairly steady for the analysis of samples from the first half of the cruise, but there may have been a shift later and the analyst reported problems with stability near the end. Studying multiple bottles fired at a single stop suggests that the Autosal is good to ±0.005 and the scatter in COMPARE looks similar. For the Portasal the multiple bottle study suggests the data is good to ±0.008, but the larger comparison between bottles and CTD showed more scatter, ~ ±0.015. Duplicate studies suggest that the Portasal was reading lower than the Autosal by ~0.007 with a standard deviation of 0.003, but the wider comparisons of bottles and CTD data suggests the Portasal is lower than the Autosal by ~0.003. Given the uncertainty in the comparisons no attempt was made to make the Autosal and Portasal results match. 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 that had more severe flags attached for other reasons. Post-cruise calibrations show primary CTD salinity is within 0.001. For details on the processing see processing report: 2008-027-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-- ---12--- 13 --14-- 15 --16- 17 --18-- 19 --20- 21 --22-- 23 !Samp Bo Pressu Temperat Salinity Sigma-t: Trans Oxygen Oxyge Fluores PAR: Salinity Fl Oxygen Fl Nitra Fl Phosph Fl Silic Fl Chloro Fl !le_ tt re:CTD ure:CTD :CTD CTD missi :Disso n:Dis cence: CTD :Bottle ag :Disso ag te_pl ag ate: ag ate: ag phyll: ag !Numb ~u vity: lved: solve CTD: ~o lved:B ~o ~Nitr ~o Bottle ~o Bottl ~o Extrac ~o !er mb CTD CTD: d:CTD Seapoin tt ottle: tt ite:B tt tt e tt ted: tt ! er Volume :Mass t le Volume le ottle le le le Bottle le !---- -- ------ -------- -------- -------- ----- ------ ----- ------- ------ -------- -- ------ -- ----- -- ------ -- ----- -- ------ -- *END OF HEADER 666 20 4.8 9.7684 28.9175 22.2694 31.3 4.80 209.8 0.396 0.6 19.2441 3 4.810 0 16.1 0 1.55 0 29.3 0 0.68 0 665 19 9.6 9.3354 30.4388 23.5236 46.8 4.62 201.5 0.304 0.5 -99.0000 0 4.638 0 18.3 0 1.70 0 32.3 0 0.45 0 664 18 19.6 9.6538 31.1364 24.0184 49.2 4.74 206.5 0.274 0.5 -99.0000 0 -99.000 0 -99.0 0 -99.00 0 -99.0 0 -99.00 0 663 17 19.9 9.6562 31.1285 24.0119 49.2 4.73 206.3 0.273 0.5 -99.0000 0 4.775 0 16.0 0 1.59 0 28.3 0 0.34 6 662 16 29.9 9.5136 31.3730 24.2254 50.2 4.76 207.6 0.204 0.5 -99.0000 0 4.795 0 16.9 0 1.66 0 29.0 0 0.24 0 661 15 39.9 9.1438 31.7353 24.5665 51.0 4.53 197.4 0.149 0.5 -99.0000 0 -99.000 0 -99.0 0 -99.00 0 -99.0 0 -99.00 0 660 14 40.2 9.1670 31.7411 24.5674 51.1 4.53 197.5 0.142 0.5 -99.0000 0 4.586 0 18.5 0 1.79 0 30.1 0 0.14 0 659 13 49.8 8.8388 31.8296 24.6871 50.9 4.29 186.9 0.133 0.5 -99.0000 0 4.334 0 19.0 0 1.81 0 31.4 0 0.13 0 658 12 75.1 8.2142 32.0950 24.9880 50.6 3.79 165.1 0.118 0.5 -99.0000 0 -99.000 0 -99.0 0 -99.00 0 -99.0 0 -99.00 0 657 11 74.7 8.2146 32.0937 24.9869 50.5 3.79 165.1 0.116 0.5 -99.0000 0 3.835 0 22.9 0 2.04 0 39.9 0 0.09 0 656 10 99.9 7.3213 32.5758 25.4919 50.5 3.02 131.5 0.099 0.5 -99.0000 0 3.070 0 26.6 0 2.34 0 50.7 0 0.06 0 655 9 124.0 6.8266 33.1026 25.9734 49.6 2.58 112.0 0.092 0.5 -99.0000 0 2.569 0 28.9 0 2.50 0 57.3 0 -99.00 0 654 8 149.9 6.7231 33.1808 26.0487 49.4 2.53 110.1 0.090 0.5 -99.0000 0 -99.000 0 -99.0 0 -99.00 0 -99.0 0 -99.00 0 653 7 149.3 6.7225 33.1810 26.0489 49.5 2.52 109.8 0.087 0.5 -99.0000 0 2.519 0 29.9 0 2.51 0 58.7 0 -99.00 0 652 6 174.5 6.6730 33.2185 26.0850 48.9 2.43 105.9 0.089 0.5 -99.0000 0 2.423 6 30.1 0 2.54 0 60.3 0 -99.00 0 651 5 199.8 6.6488 33.2394 26.1046 48.5 2.41 105.0 0.088 0.5 -99.0000 0 2.416 0 30.4 6 2.57 6 61.2 6 -99.00 0 650 4 249.6 6.6219 33.2630 26.1268 49.0 2.37 103.2 0.088 0.5 33.2675 3 2.355 0 28.4 0 2.46 0 57.4 0 -99.00 0 649 3 299.7 6.5940 33.2896 26.1514 46.0 2.33 101.2 0.089 0.5 -99.0000 0 -99.000 0 -99.0 0 -99.00 0 -99.0 0 -99.00 0 648 2 299.8 6.5940 33.2896 26.1514 46.2 2.33 101.2 0.090 0.5 33.2931 3 2.327 0 30.5 0 2.63 0 64.6 0 -99.00 0 647 1 312.9 6.5947 33.2901 26.1517 46.4 2.34 101.6 0.088 0.5 -99.0000 0 2.447 0 30.4 0 2.61 0 63.9 0 -99.00 0
