Sample Number 251: HPLC:Bottle - CV > 10% for TChl-a. 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-- 19 --20-- 21 --22-- 23 --24-- 25 ---26-- ---27-- ---28-- ---29-- ---30-- ---31-- ---32-- ---33-- ---34-- ---35-- ---36-- ---37-- ---38-- ---39-- ---40-- ---41-- ---42-- ---43-- ---44-- ---45-- ---46-- ---47-- ---48-- ---49-- ---50-- 51 !Samp Bo Pressu Temperat Salinity Sigma-t: Trans Oxygen Oxyge Fluores PAR: Nitra Fl Phosph Fl Silic Fl Chloro Fl Dimeth Fl Dimeth Fl Dimeth Fl HPLC: HPLC: HPLC: HPLC: HPLC: HPLC: HPLC: HPLC: HPLC: HPLC: HPLC: HPLC: HPLC: HPLC: HPLC: HPLC: HPLC: HPLC: HPLC: HPLC: HPLC: HPLC: HPLC: HPLC:B- HPLC: Fl !le_ tt re:CTD ure:CTD :CTD CTD missi :Disso n:Dis cence: CTD te_pl ag ate: ag ate: ag phyll: ag yl_ ag ylsulf ag ylsulf ag Chl-c3: Chlide- MgDVP: Chl-c2: Chl-c1: Me- Peri: Pheide- But- Fuco: Neo: Pras: Viola: Hex- Diadino Allo: Diato: Zea: Lut: Chl-b: DVChl- Chl-a: Phe: Car: TChl-a: ag !Numb ~u vity: lved: solve CTD: ~Nitr ~o Bottle ~o Bottl ~o Extrac ~o Sulphi ~o ~_Diss ~o ~nate_ ~o Bottle a: Bottle Bottle Bottle chlide: Bottle a: fuco: Bottle Bottle Bottle Bottle fuco: :Bottle Bottle Bottle Bottle Bottle Bottle a: Bottle Bottle Bottle Bottle : !er mb CTD CTD: d:CTD Seapoin ite:B tt tt e tt ted: tt de: tt olved: tt Total: tt Bottle Bottle Bottle Bottle Bottle Bottle HP !
