Sample Number 103: OXY:Bottle - bubble under stopper; looks ok in comparison of titrated samples and Oxygen:Dissolved:CTD. Sample Number 458: Bottle Number 24 - bad air leak at top of Niskin; OXY:Bottle - looks ok in comparison of titrated samples and Oxygen:Dissolved:CTD but it is hard to judge so close to the surface. Sample Number 475: NUTS:Bottle - broken test tube and bad result. Sample Number 474: NUTS:Bottle - sample thawed and refrozen. Sample Number 477: NUTS:Bottle - sample lost. Sample Number 528: SAL:Bottle - sample was not sealed properly. Insert not fully pushed in. This value looks ok in comparison to Salinity:CTD, but it is hard to judge so near the surface; NUTS:Bottle - sample thawed and refrozen. Sampling Methods are expressed with the following codes ------------------------------------------------------- ROS - Rosette sample collected from approximately 5m depth. USW - Sample drawn from a pumped seawater supply provided to the ship laboratory from a nominal depth of 4.5 metres. Analysis methods: ----------------- Salinity samples were collected in 200 ml type ll glass bottles with reusable silicone inserts supplied by Xiamen Cuten Accessories Industry Limited and screw caps supplied by Ocean Scientific International Limited. They were analyzed in a temperature-controlled lab on a Guildline 8400B Salinometer (S/N 68572) standardized with IAPSO standard seawater within 9-11 days after the end of the cruise. The duplicate analysis is in file 2012-001_SAL.pdf. Oxygen samples were analyzed on an automated Winkler titration system (Brinkmann Dosimat model 765 and a PC950 Colorimeter controlled by AutoOxy software V3.4) with modifications based on Carpenter (1965) and adhering to WOCE protocols (Culberson 1991). All samples were analyzed at sea. For details of the duplicate analysis see file 2012-001_OXY.pdf. Nutrient samples were collected in plastic tubes. One set of samples was collected and immediately quick frozen in aluminum blocks stored in -20 freezer. Another set of samples from 400 dbar and deeper (to be used for silicate analysis) was collected and stored at 4C in the dark. All samples were returned to IOS for analysis using an Astoria analyzer following methods described in IOS Nutrient Methods (1996) Barwell-Clarke and Whitney. For precision and duplicate analysis see file 2012-001_NUT.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. 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 at -20C for 24 hours and analyzed 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). Chlorophyll samples were analyzed on board ship in a controlled temperature lab. When duplicate samples were collected the average of two samples is reported. Variability is assessed as the CV% (std dev / mean*100). For details on duplicate samples see file 2012-001_CHL.pdf. Phaeopigment data are provided for information only and no quality flags are assigned to them. 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.

Data Processing Notes: ---------------------- Transmissivity and PAR data are nominal and unedited except that some records were removed in editing temperature and salinity. For details on how the transmissivity calibration parameters were calculated see the document Transmissivity_Calculation.pdf. The calibration of the Oxygen:Dissolved:CTD channel was done using the method described in the Sea-Bird Application Note #64-2 (Sea-Bird_64-2_Feb2010.pdf). Fluorescence data were recalibrated to correct an error in the scale factor used in the original conversion. The data are still considered nominal and are unedited. For details on the processing see processing report: 2012-001-proc.pdf.

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-- !Eve Station_ Sample Samp Date:UTC Time: Latitud Longitu INS: Pressu Temperat Salinity Transmis Oxygen Oxyge Fluores PAR: Salinity Fl Oxygen: Oxyge Fl Nitrat Fl Phospha Fl Silica Fl Chloro Fl Phaeo- !nt_ Name _ le_ UTC e de LOCATION re:CTD ure:CTD :CTD sivity: :Disso n:Dis cence: CTD :Bottle ag Dissolv n:Dis ag e_plus ag te: ag te: ag phyll: ag Pigmen !Num Method Numb CTD lved: solve CTD: ~o ed: ~ed:B ~o _Nitri ~o Bottle ~o Bottle ~o Extrac ~o t:Extr !ber er CTD: d:CTD Wetlabs tt Bottle: ottle tt te: tt tt tt ted: tt acted: !
