Emptied some sample to mix. 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 1.6 months after collection. The duplicate analysis is in file 2012-013_SAL.pdf. Oxygen samples were analyzed at sea on an automated Winkler titration system (Brinkmann Dosimat model 665 for titrations, Dosimat model 865 for dispensing standards and a PC950 Colorimeter controlled by AutoOxy software V3.4) with modifications based on Carpenter (1965) and adhering to WOCE protocols (Culberson 1991). For details on duplicate analysis see file 2012-013_OXY.pdf. Nutrient samples were collected in plastic tubes and quick frozen in aluminum blocks stored in -20 freezer. One 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. They were analyzed using an Astoria analyzer following methods described in Barwell-Clarke and Whitney (1996). For precision and duplicate details see file 2012-013_NUT.pdf. NOTE: July 2013: A correction has been applied to NIT:Bottle and PHOS: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 -80C 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 see file 2012-013_CHL.pdf. Phaeopigment data are provided for information only and no quality flags are assigned to them. Note: The variability between replicates was higher than usual and the values are lower than they typically are in comparison to HPLC Chlorophyll:Extracted. 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 2012-013_DMS_report.pdf and for duplicates see 2012-013_DMS.pdf. The minimum detectable level for DMSP in this file is 0.1 nmol/l, so “0” values should be interpreted as <0.10 nmol/l. For details on analysis see document 2012-013_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 ~6-7 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: ---------------------- Fluorescence, 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 Oxygen:Dissolved:CTD calibration was done using the method described in the Sea-Bird Application Note #64-2 (Sea-Bird_64-2_Jun2012.pdf) with a modification allowing a small offset. For further processing details see the processing report 2012-013-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 !Samp Bo Bo Pressu Temperat Salinity Sigma-t: Trans Oxygen Oxyge Fluores Salinity Fl !le_ tt tt re:CTD ure:CTD :CTD CTD missi :Disso n:Dis cence: :Bottle ag !Numb ~u ~u vity: lved: solve CTD: ~o !er mb en CTD CTD: d:CTD Seapoin tt ! er ce Volume :Mass t le !---- -- -- ------ -------- -------- -------- ----- ------ ----- ------- -------- -- *END OF HEADER 618 19 18 299.5 3.8365 33.8915 26.9466 67.1 1.57 68.5 0.071 -99.0000 0 617 18 17 399.9 3.8394 34.0195 27.0482 67.2 1.07 46.7 0.072 -99.0000 0 616 17 16 600.3 3.6363 34.1923 27.2060 67.4 0.64 27.8 0.072 -99.0000 0 615 16 15 799.9 3.2216 34.3082 27.3381 67.4 0.55 23.9 0.072 -99.0000 0 614 15 14 1000.7 2.8997 34.3781 27.4234 67.5 0.52 22.6 0.072 -99.0000 0 613 14 13 1250.3 2.5567 34.4503 27.5112 67.6 0.51 22.1 0.072 -99.0000 0 612 13 12 1499.6 2.3116 34.5066 27.5769 67.6 0.53 23.2 0.072 -99.0000 0 611 12 11 2000.0 1.9579 34.5801 27.6643 67.7 1.22 52.9 0.066 -99.0000 0 610 11 10 2498.8 1.7226 34.6266 27.7197 67.7 1.91 83.1 0.063 -99.0000 0 609 10 8 2999.4 1.5799 34.6549 27.7531 67.8 2.50 108.8 0.061 -99.0000 0 608 4 7 3500.1 1.5115 34.6716 27.7715 67.9 2.92 126.9 0.061 -99.0000 0 607 8 5 4001.2 1.5025 34.6805 27.7793 67.8 3.16 137.3 0.061 -99.0000 0 606 7 3 4300.9 1.5183 34.6837 27.7807 67.0 3.22 139.7 0.061 -99.0000 0 605 5 9 2999.4 1.5799 34.6549 27.7531 67.8 2.50 108.7 0.061 34.6584 3 604 9 6 3699.2 1.5033 34.6757 27.7754 67.9 3.03 131.7 0.061 34.6783 3 603 3 4 4001.1 1.5024 34.6804 27.7792 67.8 3.16 137.3 0.061 34.6823 3 602 2 2 4300.7 1.5184 34.6838 27.7808 67.0 3.22 139.7 0.061 34.6847 3 601 1 1 4300.8 1.5185 34.6837 27.7807 67.0 3.21 139.6 0.061 34.6844 3
