Sample Number 186: Bottle Number 22 - leaking; no oxygen sensor data available to check the value of OXY:Bottle. Sample Number 187: OXY:Bottle - very stepped curve, endpoint likely overshot - no oxygen sensor data available to check the value. Analysis methods: ----------------- Salinity samples were collected in glass bottles and analyzed at IOS on a Guildline model 8400B Autosal standardized with IAPSO standard seawater. For details on duplicate analysis see file 2010-014_SAL.pdf. Oxygen samples were analyzed at sea using an automated Winkler titration system with modifications based on Carpenter (1965) and adhering to WOCE protocols (Culberson 1991). The titration system consists of a Brinkmann 665 Dosimat, a UV light source and a UV detector with a 365 nm filter custom built by Scripps Institution of Oceanography. For details on duplicate analysis see file 2010-014_OXY.pdf. Nutrient samples were collected in plastic tubes. Most samples were analyzed frozen at IOS using an Astoria autoanalyzer following methods described in Barwell-Clarke and Whitney (1996). Deep silicate samples (400 dbar and below) were analyzed cool at IOS. For precision and duplicate analysis see file 2010-014_NUT.pdf. Chlorophyll samples were filtered onto 25mm GF/F filters and stored in glass scintillation vials at -20C prior to analysis. Samples were extracted in 90% acetone for 24 hours and analyzed at sea on a Turner 10AU fluorometer which is calibrated annually with commercially pure chlorophyll a (Sigma). Fluorescence readings taken before and after acidification were used to calculate chlorophyll and phaeopigment concentrations (Holm-Hansen et al 1965). Phaeopigment data are provided for information only and no quality flags are assigned to them. For details on duplicates see file 2010-014_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 2010-014_DMS_report.pdf and for duplicates see 2010-014_DMS.pdf. The minimum detectable level for DMSP is 0.10 nM, so “0” values should be interpreted as <0.10. For details on analysis see document 2010-014_DMS_report.pdf. HPLC samples were filtered onto 47mm 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 ~4 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.

The quality of the SBE Dissolved Oxygen data is lower than usual for both sensors because recalibration was based on observations from very few casts, and the fits of bottles against CTD produced significantly different fits for some casts from others. Similar problems were found in sensor #1176 (CTD#0506) on some other 2010 cruises and appear to be associated with CTD communication problems. For Dissolved Oxygen Sensor #1438 there is evidence of hysteresis, so data from below 2200 dbar have been replaced with pad values. In June 2011 it was discovered that the wrong information was used for recalibration of the SBE Dissolved Oxygen sensor. Sensor #1483 was actually used for this cruise, rather than sensor #1438 as originally recorded. The SBE Dissolved Oxygen channel was reprocessed after an initial study determined that the differences were significant. A new recalibration scheme was found by rerunning the bottle comparison. The files were then merged with all the other channels from the original processing. The hysteresis noted in the original processing remains, and the quality of the data is still considered of lower quality than usual. For details see the notes at the end of the processing report 2010-014-proc.pdf. For details on the processing see processing report: 2010-014-proc.pdf NOTE: July 2013: A correction has been applied to Nitrate_plus_Nitrite:Bottle and Phosphate:Bottle data from deep-water cruises analyzed at IOS between 2009 and 2012. For details see the report: Corrections_to_Nitrate_and_Phosphate_Data_2009-2012.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 !Samp Bott Bott Pressu Temperat Salinity Sigma-t: Trans Fluores Salinity Fl Oxygen: Fl Nitra Fl Phosph Fl Silic Fl !le_ le_ le:F re:CTD ure:CTD :CTD CTD missi cence: :Bottle ag Dissolv ag te_pl ag ate: ag ate: ag !Numb Numb ~ng_ vity: CTD: ~o ed: ~o ~Nitr ~o Bottle ~o Bottl ~o !er er Sequ CTD Seapoin tt Bottle: tt ite:B tt tt e tt ! ence t le Volume le ottle le le le !---- ---- ---- ------ -------- -------- -------- ----- ------- -------- -- ------- -- ----- -- ------ -- ----- -- *END OF HEADER 187 23 23 5.3 15.2803 31.6873 23.3855 46.1 0.543 31.6683 0 6.062 4 0.2 0 0.41 0 5.4 0 186 22 22 11.3 14.9929 31.6638 23.4292 45.3 1.136 31.6676 0 6.060 4 0.2 0 0.41 0 5.3 0 185 21 21 26.7 14.8708 31.8561 23.6033 48.0 2.077 31.7280 0 6.022 0 0.2 0 0.43 0 5.3 0 184 20 20 48.3 10.6869 32.4995 24.9096 57.4 1.207 32.4679 0 6.517 0 4.5 0 0.84 0 6.6 0 183 19 19 77.7 7.9441 32.5277 25.3666 61.1 0.194 32.5435 0 6.537 6 8.4 6 1.01 6 10.7 6 182 18 18 101.2 7.4771 33.2152 25.9731 61.6 0.104 32.6776 0 6.184 0 11.7 0 1.17 0 14.1 0 181 17 17 126.0 6.9236 33.0404 25.9114 61.7 0.081 33.0347 0 5.752 0 16.4 0 1.37 0 19.8 0 180 16 16 151.8 6.6858 33.4302 26.2502 61.8 0.058 33.4347 0 5.185 0 20.4 0 1.59 0 26.5 0 179 15 15 175.6 6.5804 33.6563 26.4423 61.7 0.057 33.6593 0 4.603 0 24.2 0 1.76 0 33.4 0 178 14 14 200.9 6.3797 33.7725 26.5602 61.7 0.049 33.7724 0 4.125 0 26.5 0 1.93 0 38.9 0 177 13 13 250.8 5.8882 33.8787 26.7064 61.6 0.050 33.8785 0 2.858 0 32.6 0 2.35 0 53.3 0 176 12 12 301.0 5.5148 33.9228 26.7868 61.8 0.059 33.9285 0 1.994 6 36.3 0 2.61 0 63.5 0 175 11 11 400.5 5.0418 34.0052 26.9076 62.0 0.058 34.0124 0 1.125 0 41.0 0 2.86 0 78.4 0 174 10 10 601.8 4.0929 34.1292 27.1096 62.2 0.068 34.1331 0 0.580 0 43.4 0 3.14 0 104.3 0 173 9 9 800.9 3.5817 34.2500 27.2573 62.2 0.073 34.2509 0 0.388 0 44.8 0 3.10 3 122.9 0 172 8 8 1001.2 3.3046 34.3673 27.3775 62.2 0.073 34.3696 0 0.273 0 45.0 0 3.27 0 135.8 0 171 7 7 1251.7 2.8050 34.4439 27.4845 62.2 0.074 34.4456 0 0.355 6 44.7 6 3.24 6 151.2 6 170 6 6 1502.9 2.3979 34.5064 27.5696 62.3 0.073 34.5081 0 0.686 0 45.4 0 3.11 0 162.2 0 169 5 5 2001.2 1.9525 34.5852 27.6688 62.3 0.073 34.5864 0 1.374 0 43.3 0 3.02 0 173.4 0 168 4 4 2500.4 1.7682 34.6218 27.7124 62.2 0.073 34.6230 0 1.864 0 41.1 0 2.92 0 176.0 0 167 3 3 3001.4 1.6636 34.6444 27.7384 62.1 0.012 34.6460 0 2.274 0 40.6 0 2.86 0 176.9 0 166 2 2 3001.0 1.6634 34.6445 27.7385 62.0 0.013 34.6435 6 2.263 0 40.8 0 2.85 0 176.9 0 165 1 1 3052.3 1.6544 34.6464 27.7407 62.0 0.015 34.6471 0 2.310 0 41.0 0 2.88 0 177.5 0
