COUNTRY : Canada PROJECT : Line P SCIENTIST : Robert M. PLATFORM : John P. Tully *LOCATION GEOGRAPHIC AREA : North-East Pacific STATION : P20 EVENT NUMBER : 43 LATITUDE : 49 33.97000 N !

(deg min) WATER DEPTH : 3945 *INSTRUMENT TYPE : Sea-Bird CTD MODEL : SBE-911plus SERIAL NUMBER : 0550 *COMMENTS Samples Number 230 and 231: DIC:Bottle - large difference from duplicate Niskin. Sample Number 247: SAL:Bottle - differs from SAL:CTD by 0.87 units and looks like it might be from bottle at 125 dbar. 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 at sea on an automated Winkler titration system following the procedures of Carpenter (1965). A Brinkmann model 665 Dosimat and model PC910 Colorimeter was controlled by Visual-Basic program to titrate the oxygen samples. Nutrient samples were analysed fresh at sea using the new Astoria system following methods described in Barwell-Clarke and Whitney (1996). For duplicates and precision see file 2007-013_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 -20°C 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 2007-013_DMS_report.doc. For details on duplicates see file 2007-013_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 2007-013_DIC.pdf and 2007-013_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: 2007-013-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 Alkalin 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 ity: 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 252 24 6.4 8.5250 32.4824 25.2457 51.4 7.10 309.1 0.696 32.4828 0 6.796 0 10.6 0 1.15 0 13.9 0 2019.87 0 2182.02 0 251 23 12.1 8.3192 32.4822 25.2762 51.1 7.12 310.0 0.744 32.4823 0 7.111 0 10.6 0 1.13 0 13.9 0 2023.93 0 2168.78 0 250 22 25.6 8.1628 32.4826 25.2995 50.2 7.14 310.7 1.077 32.4847 0 7.178 0 10.6 0 1.13 0 13.7 0 2023.81 0 2182.05 0 249 21 51.2 6.6105 32.5381 25.5568 53.2 7.22 314.2 1.448 32.5387 0 7.036 0 11.7 0 1.22 0 14.4 0 2032.59 0 2191.58 0 248 20 76.6 6.3777 32.5461 25.5928 59.0 7.12 309.8 0.462 32.5465 0 7.146 0 12.0 0 1.25 0 14.8 0 2034.67 0 2196.62 0 247 19 101.7 6.2274 32.5695 25.6302 60.2 6.99 304.3 0.160 -99.0000 5 7.107 0 12.6 0 1.29 0 15.9 0 2042.22 0 2188.08 0 246 18 125.4 5.7738 33.4595 26.3891 60.8 5.39 234.6 0.049 33.4494 0 5.531 0 22.5 0 1.76 0 32.8 0 2074.94 0 2239.14 0 245 17 151.8 5.7953 33.7474 26.6141 60.8 4.80 208.5 0.037 33.7448 0 4.893 0 25.0 0 1.94 0 40.2 0 2165.09 0 2253.23 0 244 16 176.6 5.5340 33.7963 26.6844 60.6 4.20 182.8 0.038 33.7962 0 4.325 0 27.8 0 2.06 0 47.9 0 2187.81 0 2264.52 0 243 15 200.7 5.1826 33.8071 26.7344 60.6 3.70 161.1 0.038 33.8099 0 3.864 0 30.2 0 2.24 0 55.2 0 2209.25 0 2267.11 0 242 14 251.4 4.7137 33.8445 26.8170 60.7 2.76 119.8 0.040 33.8467 0 2.854 0 34.7 0 2.55 0 67.4 0 2249.93 0 2273.34 0 241 13 301.5 4.5393 33.8929 26.8745 60.9 1.97 85.5 0.042 33.8913 0 2.149 0 38.2 0 2.77 0 76.4 0 2271.24 0 2283.38 0 240 12 401.2 4.1803 34.0034 27.0005 61.3 1.13 49.0 0.043 34.0055 0 1.196 0 42.0 0 3.04 0 94.3 0 2309.96 0 2306.04 0 239 11 601.5 3.7717 34.1626 27.1689 61.3 0.58 25.3 0.043 34.1620 0 0.678 0 44.0 6 3.21 6 114.9 6 2328.98 0 2328.73 0 238 10 801.7 3.3569 34.2907 27.3114 61.3 0.36 15.5 0.043 34.2893 0 0.401 0 44.7 0 3.28 0 132.6 0 2351.89 0 2358.43 0 237 9 999.8 3.0106 34.3706 27.4074 61.3 0.28 12.0 0.043 34.3700 0 0.406 0 45.3 0 3.32 0 145.8 0 2384.31 0 2371.65 0 236 8 1250.4 2.6191 34.4503 27.5059 61.3 0.37 16.0 0.043 34.4501 0 0.389 0 45.3 0 3.31 0 154.9 0 2393.20 0 2388.54 0 235 7 1500.9 2.3292 34.5101 27.5783 61.4 0.60 25.9 0.040 34.5098 0 0.727 0 44.9 0 3.26 0 167.9 0 2398.77 0 2406.88 0 234 6 2000.1 1.9331 34.5884 27.6729 61.5 1.34 58.0 0.038 34.5872 0 1.333 0 42.9 0 3.14 0 175.2 0 2382.63 0 2403.09 0 233 5 2500.7 1.7211 34.6315 27.7238 61.5 1.99 86.5 0.035 34.6308 0 2.020 0 40.9 0 3.01 0 176.2 0 2370.04 0 2417.09 0 232 4 3000.6 1.5778 34.6589 27.7564 61.5 2.60 113.1 0.033 34.6601 0 2.586 0 39.1 0 2.93 0 175.1 0 2351.94 0 2414.41 0 231 3 3500.8 1.5369 34.6720 27.7700 61.4 2.95 128.1 0.032 34.6712 0 2.921 0 38.3 0 2.81 0 175.0 0 2343.02 36 2423.35 6 230 2 3501.1 1.5370 34.6719 27.7699 61.4 2.95 128.1 0.032 34.6719 0 2.950 0 38.3 0 2.81 0 174.8 0 2345.04 3 2423.86 0 229 1 4015.1 1.5410 34.6800 27.7761 60.6 3.16 137.4 0.032 34.6797 0 3.108 0 38.0 0 2.77 0 177.5 0 2346.59 0 2419.10 0
