Analysis methods: ----------------- Salinity samples were collected in glass bottles and analyzed on Guildline model 8400B Autosal Salinometers which are standardized with IAPSO standard seawater. Oxygen samples were 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 2007-001_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 -20ºC 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 2007-001_DMS_report.doc. For details on duplicates see file 2007-001_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 2007-001_DIC.pdf and 2007-001_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: 2007-001-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-- 24 !Samp Bo Pressu Temperat Salinity Sigma-t: Trans Oxygen Oxyge Fluores Salinity Fl Oxygen: Fl Nitra Fl Phosph Fl Silic Fl Carbon: Fl Alkali Fl !le_ tt re:CTD ure:CTD :CTD CTD missi :Disso n:Dis cence: :Bottle ag Dissolv ag te_pl ag ate: ag ate: ag Dissolv ag nity: ag !Numb ~u vity: lved: solve CTD: ~o ed: ~o ~Nitr ~o Bottle ~o Bottl ~o ed:Inor ~o Total: ~o !er mb CTD CTD: d:CTD Seapoin tt Bottle: tt ite:B tt tt e tt ganic: tt Bottle tt ! er Volume :Mass t le Volume le ottle le le le Bottle le le !---- -- ------ -------- -------- -------- ----- ------ ----- ------- -------- -- ------- -- ----- -- ------ -- ----- -- ------- -- ------ -- *END OF HEADER 269 24 5.1 5.6550 32.5812 25.7089 52.0 7.11 309.3 0.294 32.5837 0 7.061 0 15.1 0 1.40 0 20.4 0 2038.00 0 -99.0 0 268 23 9.4 5.6581 32.5815 25.7088 52.9 7.10 309.0 0.261 32.5817 0 7.138 0 15.1 0 1.40 0 20.6 0 2043.37 0 2172.6 0 267 22 25.5 5.6594 32.5814 25.7086 52.9 7.09 308.7 0.415 32.5819 0 7.257 0 15.2 0 1.41 0 20.4 0 2051.39 0 2190.6 0 266 21 50.2 5.6583 32.5814 25.7087 53.0 7.08 308.1 0.584 32.5821 0 7.045 0 15.2 0 1.42 0 20.3 0 2050.09 0 2184.7 0 265 20 73.5 5.6594 32.5817 25.7088 53.0 7.06 307.1 0.570 32.5819 0 7.037 0 15.0 0 1.41 0 20.3 0 2051.76 0 2188.7 0 264 19 100.2 5.6607 32.5853 25.7115 53.3 7.00 304.7 0.537 32.5868 0 7.025 0 15.3 0 1.41 0 20.4 0 2048.78 0 2187.3 0 263 18 125.4 5.9941 33.6151 26.4849 54.9 3.26 141.6 0.077 33.5892 0 3.543 0 30.3 0 2.24 0 44.4 0 2194.50 0 2245.3 0 262 17 147.9 5.5612 33.7052 26.6091 54.9 3.62 157.6 0.049 33.7036 0 3.656 0 30.6 0 2.23 0 47.2 0 2196.35 0 2247.1 0 261 16 176.0 5.0808 33.7573 26.7066 55.4 3.61 156.8 0.037 33.7557 0 3.677 0 30.9 6 2.27 6 52.5 6 2208.71 0 2252.4 0 260 15 199.1 4.9213 33.7893 26.7501 55.4 2.97 129.1 0.039 33.7886 0 3.015 0 33.9 0 2.48 0 59.3 0 2234.52 0 2273.1 0 259 14 253.1 4.6667 33.8503 26.8268 55.5 2.06 89.7 0.037 33.8504 0 2.085 0 38.1 0 2.75 0 70.0 0 2263.73 0 2276.6 0 258 13 299.8 4.6827 33.9209 26.8811 55.8 1.31 56.8 0.037 33.9193 0 1.339 0 41.6 0 2.94 0 77.4 0 2289.84 0 2261.1 3 257 12 400.2 4.3335 34.0210 26.9984 56.0 0.84 36.7 0.037 34.0206 0 0.832 0 43.3 0 3.11 0 90.5 0 2314.39 0 2290.2 0 256 11 598.4 3.7197 34.1790 27.1871 56.1 0.54 23.6 0.039 34.1779 0 0.559 0 44.6 0 3.21 0 114.9 0 2344.75 0 2331.9 0 255 10 800.2 3.3344 34.2939 27.3161 56.1 0.38 16.7 0.037 34.2940 0 0.362 0 45.2 0 3.26 0 131.7 0 2366.08 0 2354.0 0 254 9 999.6 2.9634 34.3709 27.4120 56.2 0.37 16.1 0.037 34.3703 0 0.347 0 45.4 0 3.26 0 143.5 0 2381.21 0 2366.9 0 253 8 1251.0 2.6125 34.4459 27.5029 56.2 0.41 17.9 0.037 34.4488 0 0.380 0 45.7 0 3.27 0 156.8 0 2389.90 0 2390.3 0 252 7 1501.7 2.3485 34.5006 27.5691 56.3 0.59 25.8 0.036 34.5007 0 0.552 0 45.2 0 3.25 0 163.8 0 2387.81 0 2392.5 0 251 6 2000.1 1.9502 34.5831 27.6673 56.3 1.32 57.3 0.033 34.5820 0 1.268 0 43.3 0 3.09 0 172.4 0 2379.93 0 2420.2 0 250 5 2503.6 1.7123 34.6300 27.7232 56.3 2.02 87.8 0.030 34.6294 0 1.966 0 41.6 0 2.94 0 173.4 0 2369.47 6 2414.5 36 249 4 3000.9 1.5843 34.6563 27.7539 56.3 2.58 112.0 0.028 34.6561 0 2.494 0 40.1 0 2.83 0 171.6 0 2353.82 0 2421.2 0 248 3 3500.1 1.5171 34.6726 27.7719 56.3 3.01 130.6 0.027 34.6727 0 2.921 0 38.8 0 2.74 0 170.1 0 2340.64 0 2425.4 0 247 2 4002.8 1.5036 34.6820 27.7804 56.2 3.28 142.4 0.026 34.6817 0 3.214 0 38.2 0 2.69 0 170.1 0 2341.81 0 2421.1 0 246 1 4305.3 1.5177 34.6854 27.7821 55.7 3.36 146.0 0.026 34.6846 0 3.414 0 38.1 0 2.68 0 174.5 0 2337.17 0 2425.6 0
