Analysis methods: ----------------- Salinity samples were collected in glass bottles and analyzed on a Guildline model 8400B Autosal or a Guildline Portasal 8410A. 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-- ---11--- 12 --13-- 14 --15- 16 --17-- 18 --19- 20 ---21-- 22 --23-- 24 ---25--- 26 !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 pH: Fl !le_ tt re:CTD ure:CTD :CTD CTD missi :Disso n:Dis cence: :Bottle ag :Disso ag te_pl ag ate: ag ate: ag Dissolv ag nity: ag Bottle ag !Numb ~u vity: lved: solve CTD: ~o lved:B ~o ~Nitr ~o Bottle ~o Bottl ~o ed:Inor ~o Total: ~o ~o !er mb CTD CTD: d:CTD Seapoin tt ottle: tt ite:B tt tt e tt ganic: tt Bottle tt tt ! er Volume :Mass t le Volume le ottle le le le Bottle le le le !---- -- ------ -------- -------- -------- ----- ------ ----- ------- -------- -- ------ -- ----- -- ------ -- ----- -- ------- -- ------ -- -------- -- *END OF HEADER 266 24 4.4 8.2116 32.5228 25.3239 54.8 7.12 310.2 0.170 32.5266 0 6.938 0 11.1 0 1.10 0 12.3 0 2025.92 0 2180.1 0 7.7954 0 265 23 10.7 8.1846 32.5235 25.3284 54.9 7.12 310.1 0.201 32.5261 0 6.929 0 11.0 0 1.11 0 12.4 0 2028.05 0 2184.2 0 7.7960 6 264 22 23.8 7.7921 32.5489 25.4050 53.4 7.20 313.3 0.642 32.5471 0 6.997 0 11.0 0 1.10 0 12.1 0 2029.35 0 2192.3 0 7.7978 0 263 21 49.7 7.4376 32.5614 25.4646 52.9 7.21 313.7 1.190 32.5649 0 7.045 0 11.6 0 1.13 0 12.6 0 2030.77 0 2217.4 3 7.7897 6 262 20 74.9 6.1613 32.5847 25.6504 58.2 7.19 313.0 0.416 32.5847 0 7.138 6 13.3 0 1.24 0 15.1 0 2046.19 0 2194.5 0 7.7575 36 261 19 100.4 5.9375 32.7627 25.8185 59.0 6.48 281.8 0.147 32.7476 0 6.460 0 17.0 0 1.42 0 20.1 0 2076.18 0 2219.2 0 7.7076 0 260 18 124.3 6.0942 33.5378 26.4113 59.0 4.30 187.1 0.081 33.5328 0 4.266 0 26.3 0 1.92 0 37.4 0 2166.91 0 2265.6 0 -99.0000 0 259 17 150.1 5.9423 33.7796 26.6213 58.9 3.70 161.1 0.074 33.7788 0 4.046 0 29.9 0 2.08 0 45.0 0 2196.10 0 2271.1 0 7.5112 0 258 16 174.4 5.6230 33.8287 26.6994 58.9 3.28 142.7 0.077 33.8323 0 3.328 0 32.1 0 2.24 0 51.8 0 2213.12 0 2281.4 0 -99.0000 0 257 15 200.7 5.3691 33.8479 26.7449 59.0 2.91 126.4 0.073 33.8473 0 3.189 0 33.9 0 2.37 0 57.1 0 2231.10 0 2280.5 0 7.4459 6 256 14 250.0 5.0287 33.8715 26.8031 59.0 2.45 106.6 0.073 33.8730 0 2.672 0 36.2 0 2.53 0 64.4 0 2251.91 0 2282.6 0 -99.0000 0 255 13 300.5 4.7802 33.9183 26.8682 59.2 1.78 77.4 0.075 33.9231 0 2.069 0 39.2 0 2.72 0 73.8 0 2277.01 0 2294.7 0 7.3539 0 254 12 399.2 4.3935 34.0236 26.9940 59.5 1.00 43.4 0.077 34.0230 0 1.015 0 42.4 0 2.97 0 88.9 0 2309.23 0 2310.4 0 -99.0000 0 253 11 600.7 3.7956 34.1636 27.1673 59.7 0.54 23.3 0.077 34.1643 0 0.571 0 44.7 6 3.12 6 111.9 6 2341.43 0 2354.7 3 7.2839 0 252 10 799.9 3.3601 34.2928 27.3128 59.7 0.37 16.2 0.077 34.2927 0 0.391 0 45.7 0 3.18 0 129.6 0 2357.11 3 2367.1 3 7.2911 3 251 9 1000.8 3.0087 34.3721 27.4088 59.7 0.27 11.8 0.076 34.3744 0 0.265 0 46.5 0 3.22 0 142.6 0 2378.76 3 2384.6 3 7.2929 3 250 8 1250.5 2.6177 34.4530 27.5081 59.7 0.35 15.2 0.076 34.4532 0 0.362 0 46.5 0 3.20 0 155.9 0 2389.04 0 2400.4 0 -99.0000 0 249 7 1500.4 2.3333 34.5091 27.5771 59.7 0.57 24.9 0.073 34.5092 0 0.575 0 46.0 0 3.16 0 164.7 0 2393.19 0 2424.8 3 7.3263 0 248 6 1999.8 1.9600 34.5854 27.6684 59.8 1.25 54.5 0.070 34.5856 0 1.457 0 44.2 0 3.02 0 172.4 0 2382.81 0 2422.5 0 7.3916 0 247 5 2498.7 1.7084 34.6344 27.7270 59.9 1.99 86.6 0.067 34.6353 6 1.988 0 42.4 0 2.88 0 174.5 0 2374.84 0 2432.9 0 -99.0000 0 246 4 2498.7 1.7084 34.6343 27.7270 59.9 2.00 86.7 0.067 34.6342 0 2.200 0 42.2 0 2.88 0 174.3 0 2375.22 6 2432.9 0 -99.0000 0 245 3 2999.9 1.5926 34.6566 27.7535 59.9 2.48 107.9 0.065 34.6569 0 2.565 0 40.8 0 2.77 0 174.3 0 2359.30 0 2445.1 3 7.5050 0 244 2 3498.9 1.5509 34.6698 27.7672 59.7 2.80 121.5 0.063 34.6703 0 2.756 0 39.9 0 2.71 0 176.2 0 2353.76 0 2454.8 3 7.5291 6 243 1 3685.8 1.5605 34.6714 27.7678 59.3 2.84 123.5 0.065 34.6749 0 2.788 0 40.2 0 2.70 0 176.9 0 2352.63 0 2443.3 0 -99.0000 0
