COUNTRY : Canada PROJECT : Line P SCIENTIST : Robert M. PLATFORM : John P. Tully *LOCATION GEOGRAPHIC AREA : North-East Pacific STATION : P16 EVENT NUMBER : 47 LATITUDE : 49 17.02000 N ! (deg min) LONGITUDE : 134 39.98000 W ! (deg min) WATER DEPTH : 3636 *INSTRUMENT TYPE : Sea-Bird CTD MODEL : SBE-911plus SERIAL NUMBER : 0443 *COMMENTS Samples Number 323 to 336, 338: SAL:Bottle - run on Portasal with no standard water available; deep water used instead. Portasal values were recalibrated by subtracting 0.011 to match the Autosal results. Sample Number 335: NIT:Bottle - rerun. Sample Number 337: SAL:Bottle - sample not found. Analysis methods: ----------------- Salinity samples were collected in glass bottles and analyzed at IOS on a Guildline model 8400B Autosal standardized with IAPSO standard seawater. Samples from some casts were analyzed at sea on a Guildline Portasal; there are comments attached to those samples and all were flagged 4. For details on duplicate analysis see file 2009-009_SAL.pdf. Oxygen samples were analyzed at sea using an automated titration system consisting of a Brinkman Dosimat (model 665) and a PC 950 Colorimeter. For information on precision see file 2009-009_OXY.pdf. Nutrient samples were collected in plastic tubes and analyzed fresh at sea using an Astoria autoanalyzer following methods described in Barwell-Clarke and Whitney (1996). For information on duplicates and precision see file 2009-009_NUT.pdf. Chlorophyll samples were analyzed at sea using a Chemistry Turner Designs 10AU fluorometer which was calibrated on May 12, 2009 using pure chlorophyll a. Chlorophyll precision was determined by analyzing replicate samples drawn from one Niskin. For details on duplicates see file 2009-009_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 2009-009_DMS_report.pdf and for duplicates see 2009-009_DMS.pdf. DMSP: All sample data were discarded due to blank contamination problems. For details on analysis see document 2009-009_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 ~6 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. Carpenter, J.H. 1965.

Data Processing Notes: ---------------------- Transmissometer #1005DR was calibrated in March 2008, and drifted significantly but steadily until July 2009; then a sudden shift occurred, so that maximum values between September 2009 and July 2010 were very low, ~25%/m. In August 2010 a study was made of transmissivity that led to a decision to apply post-processing corrections to all cruises between March 2008 and June 2010. Transmissivity data from this cruise were corrected by multiplying the original values by a correction factor, which was based on assumptions that deep offshore transmissivity from a June 2009 cruise should be about 62%/m and that drift was linear with time between March 2008 and July 2009. The corrections produced reasonable results for all cruises in that time period. For details on the transmissometer post-processing see: Transmissometer_1005DR_Corrections.pdf These data should be considered estimates. For details on the processing see processing report: 2009-009-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 !Samp Bo Pressu Temperat Salinity Sigma-t: Trans Oxygen Oxyge Fluores Salinity Fl Nitra Fl Phosph Fl Silic Fl !le_ tt re:CTD ure:CTD :CTD CTD missi :Disso n:Dis cence: :Bottle ag te_pl ag ate: ag ate: ag !Numb ~u vity: lved: solve CTD: ~o ~Nitr ~o Bottle ~o Bottl ~o !er mb CTD CTD: d:CTD Seapoin tt ite:B tt tt e tt ! er Volume :Mass t le ottle le le le !---- -- ------ -------- -------- -------- ----- ------ ----- ------- -------- -- ----- -- ------ -- ----- -- *END OF HEADER 338 16 10.7 11.0262 32.4584 24.8184 -99.0 6.72 292.7 0.760 32.4595 4 -99.0 0 -99.00 0 -99.0 0 337 15 10.7 11.0256 32.4581 24.8182 -99.0 6.72 292.6 0.771 -99.0000 9 -99.0 0 -99.00 0 -99.0 0 336 14 10.5 11.0251 32.4581 24.8183 54.9 6.72 292.8 0.763 32.4590 4 -99.0 0 -99.00 0 -99.0 0 335 13 10.8 11.0243 32.4577 24.8182 -99.0 6.71 292.4 0.759 32.4608 4 7.1 2 0.95 0 12.0 0 334 12 999.8 3.0455 34.3680 27.4022 62.6 0.23 10.1 0.131 34.3695 4 -99.0 0 -99.00 0 -99.0 0 333 11 999.5 3.0461 34.3679 27.4020 62.6 0.23 10.0 0.131 34.3677 4 -99.0 0 -99.00 0 -99.0 0 332 10 1000.2 3.0463 34.3679 27.4020 -99.0 0.23 10.1 0.132 34.3679 4 -99.0 0 -99.00 0 -99.0 0 331 9 1000.7 3.0456 34.3681 27.4022 62.6 0.23 10.1 0.132 34.3684 4 -99.0 0 -99.00 0 -99.0 0 330 8 1000.3 3.0462 34.3680 27.4021 -99.0 0.23 10.1 0.131 34.3675 4 -99.0 0 -99.00 0 -99.0 0 329 7 1000.4 3.0462 34.3679 27.4020 -99.0 0.23 10.2 0.132 34.3677 4 -99.0 0 -99.00 0 -99.0 0 328 6 1000.1 3.0466 34.3678 27.4019 62.6 0.23 10.1 0.132 34.3685 4 -99.0 0 -99.00 0 -99.0 0 327 5 1000.8 3.0457 34.3680 27.4021 -99.0 0.23 10.0 0.132 34.3698 4 -99.0 0 -99.00 0 -99.0 0 326 4 1000.1 3.0462 34.3680 27.4021 -99.0 0.23 10.2 0.130 34.3677 4 -99.0 0 -99.00 0 -99.0 0 325 3 1000.3 3.0462 34.3680 27.4021 -99.0 0.23 10.0 0.129 34.3677 4 -99.0 0 -99.00 0 -99.0 0 324 2 1000.2 3.0458 34.3681 27.4022 -99.0 0.23 10.2 0.132 34.3680 4 -99.0 0 -99.00 0 -99.0 0 323 1 1000.4 3.0460 34.3681 27.4022 62.6 0.23 10.2 0.130 34.3671 4 44.6 0 3.32 0 146.5 0
