They are out of line with CTD data and look wrong in profiles. All bottle data have been flagged. Samples Number 160, 165: Carbon:Dissolved:Inorganic:Bottle and Alkalinity:Total:Bottle - Bad calibrations; Carbon:Dissolved:Inorganic:Bottle low compared to historical data. Sample Number 161: Oxygen:Dissolved:Bottle - software problem, sample data lost. Samples Number 161, 162: Carbon:Dissolved:Inorganic:Bottle and Alkalinity:Total:Bottle - Bad calibrations. Sample Number 163: Carbon:Dissolved:Inorganic:Bottle and Alkalinity:Total:Bottle - Bad calibrations; Carbon:Dissolved:Inorganic:Bottle low compared to historical data; Alkalinity:Total:Bottle - Large differences between replicates. Samples Number 166, 171, 172, 173: Alkalinity:Total:Bottle - suspect calibration. Analysis methods: ----------------- Salinity samples are collected in glass bottles and analyzed on Guildline model 8400B Autosal Salinometers which are standardized with IAPSO standard seawater. Oxygen samples are 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 2007-01_NUT.pdf. Chlorophyll samples are collected in calibrated polycarbonate bottles (~330ml), then filtered onto 25mm MFS GF/75 filters at <70mmHg vacuum. The filters are placed in glass scintillation vials and immediately frozen at -20ºC until analysis. The chlorophyll is extracted in 10 ml of 90% acetone for 24h at -20ºC, then brought to room temperature and the extract is decanted and measured using a Turner Designs Model 10 fluorometer, which has been calibrated with solutions of commercially prepared chlorophyll. 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 2007-01_DMS_Report.pdf. See file 2007-01_DMS_duplicates.pdf for duplicates analysis. 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 2007-01_DIC.pdf and 2007-01_ALK.pdf respectively. References: 1.

Non-zero values have the following significance: ---------------------------------------------------------------------------- 1 = Sample for this measurement was drawn from water bottle but not analyzed (not normally used). 2 = Acceptable measurement (not normally used). 3 = Questionable measurement (no problem observed in sampling or analysis, but value is not trusted, nonetheless; includes outlyers). 4 = Bad measurement (known problem with sampling or analysis, but not serious enough to completely discard the value). 5 = Not reported (lost sample; unredeemably bad measurement). 6 = Mean of replicate measurements. 7 = Manual chromatographic peak measurement. 8 = Irregular digital chromatographic peak integration. 9 = Sample not drawn for this measurement from this bottle (not normally used). ---------------------------------------------------------------------------- $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 tt Bottle: lu ite:B tt tt e tt ganic: tt Bottle tt ! er Volume :Mass le Volume me ottle le le le Bottle le le !---- -- ------ -------- -------- -------- ----- ------ ----- ------- -------- -- ------- -- ----- -- ------ -- ----- -- ------- -- ------ -- *END OF HEADER 183 24 6.0 7.0891 32.3984 25.3838 48.2 6.98 303.9 1.082 32.3998 0 6.964 0 10.9 0 1.15 0 12.5 0 2030.90 0 2192.1 0 182 23 10.2 7.0697 32.4096 25.3953 49.8 6.97 303.4 1.093 -99.0000 5 -99.000 5 -99.0 5 -99.00 5 -99.0 5 -99.00 0 -99.0 0 181 22 25.0 7.0374 32.4238 25.4107 50.3 6.95 302.4 1.089 32.4231 0 6.944 0 11.3 0 1.16 0 12.4 0 2070.73 0 2166.7 0 180 21 50.7 6.9834 32.4263 25.4199 52.1 6.91 301.1 0.689 32.4264 0 6.724 0 11.7 0 1.19 0 12.9 0 2029.02 0 2175.0 0 179 20 75.7 6.9420 32.4737 25.4627 54.5 6.73 293.1 0.264 32.4708 0 6.781 0 12.1 0 1.22 0 13.3 0 2049.37 0 2177.3 0 178 19 100.2 6.8604 32.8207 25.7468 55.1 5.71 248.5 0.099 32.7985 0 5.817 0 17.1 0 1.49 0 20.8 0 2079.05 0 2197.1 0 177 18 125.4 6.1900 33.4327 26.3163 55.4 4.51 196.0 0.046 33.4542 0 4.512 0 25.3 0 1.94 0 34.9 0 2159.64 0 2234.8 0 176 17 151.4 5.8460 33.6163 26.5042 55.5 4.26 185.4 0.038 -99.0000 5 -99.000 5 -99.0 5 -99.00 5 -99.0 5 -99.00 5 -99.0 5 175 16 176.4 5.6692 33.7331 26.6181 55.6 3.86 167.7 0.036 33.7336 0 3.882 0 28.9 0 2.13 0 44.7 0 2186.82 0 2248.3 0 174 15 200.6 5.5686 33.7947 26.6790 55.5 3.40 148.1 0.037 33.7890 0 3.504 0 30.7 0 2.25 0 49.5 0 2206.02 0 2256.7 0 173 14 249.2 5.3455 33.8559 26.7540 55.5 2.57 111.5 0.036 33.8545 0 2.611 0 34.6 0 2.51 0 59.5 0 2248.10 0 2274.9 3 172 13 301.8 5.0342 33.9176 26.8390 55.7 1.75 76.0 0.037 33.9159 0 1.803 0 38.6 0 2.77 0 70.5 0 2272.68 0 2294.9 3 171 12 400.5 4.5935 34.0133 26.9642 56.0 1.09 47.2 0.037 34.0125 0 1.069 0 42.1 6 3.02 6 85.9 6 2311.15 0 2301.5 3 170 11 600.8 3.9205 34.1317 27.1293 56.2 0.65 28.4 0.038 -99.0000 5 -99.000 5 -99.0 5 -99.00 5 -99.0 5 -99.00 5 -99.0 5 169 10 800.9 3.4527 34.2739 27.2889 56.2 0.36 15.5 0.038 34.2714 0 0.346 0 45.1 0 3.27 0 128.8 0 2365.87 0 2355.3 0 168 9 1001.3 3.0567 34.3613 27.3958 56.3 0.29 12.6 0.038 34.3606 0 0.291 0 45.6 0 3.30 0 143.2 0 2381.50 0 2371.3 0 167 8 1251.1 2.6854 34.4411 27.4928 56.3 0.35 15.3 0.037 34.4397 0 0.323 0 45.9 0 3.29 0 155.6 0 2400.46 0 2393.3 0 166 7 1500.6 2.3831 34.5008 27.5663 56.3 0.56 24.5 0.036 34.5266 4 0.519 0 45.4 0 3.25 0 164.8 0 2399.00 0 2398.0 3 165 6 2000.6 1.9326 34.5904 27.6745 56.4 1.36 59.2 0.033 34.5886 0 1.311 0 43.2 0 3.09 0 174.5 0 2138.44 4 2425.9 4 164 5 2502.0 1.7303 34.6309 27.7226 56.5 1.97 85.7 0.030 -99.0000 5 -99.000 5 -99.0 5 -99.00 5 -99.0 5 -99.00 5 -99.0 5 163 4 3002.3 1.6010 34.6555 27.7520 56.4 2.51 109.2 0.028 34.6560 0 2.448 0 39.8 0 2.84 0 175.7 0 2234.71 4 2434.6 46 162 3 3002.5 1.6007 34.6554 27.7519 56.3 2.51 109.2 0.028 34.6544 0 2.437 0 39.8 0 2.84 0 175.8 0 2229.19 4 2430.4 4 161 2 3502.7 1.5667 34.6681 27.7647 56.2 2.81 121.9 0.028 34.6668 0 -99.000 5 39.1 0 2.78 0 177.7 0 2319.83 4 2461.8 4 160 1 3684.4 1.5683 34.6708 27.7667 56.0 2.87 124.8 0.028 34.6703 0 2.962 0 39.0 0 2.78 0 179.2 0 2257.91 4 2439.4 4
