Analysis methods: ----------------- Salinity samples were collected in 200 ml type ll glass bottles with disposable plastic inserts 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 2 to 21 days after collection. For details on duplicate analysis see file 2013-01_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 2013-01_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 2013-01_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 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 at IOS 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 duplicates see file 2013-01_CHL.pdf. Flags and comments apply to chlorophyll values only. No flags or comments are assigned for Phaeopigment values. 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 2013-01_DMS_Report.pdf and for duplicates see 2013-01_DMS.pdf. References: 1.

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 2013-01-proc.pdf. $REMARKS Flag channels were initialized with zeros. Non-zero values have the following significance: ---------------------------------------------------------------------------------- 1 = Sample for this measurement was collected but not analyzed. Sample lost. 2 = Acceptable measurement. 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 !Samp Bo Bo Pressu Temperat Salinity Sigma-t: Trans Oxygen Oxyge Fluores Salinity Fl Oxygen: Oxyge Fl !le_ tt tt re:CTD ure:CTD :CTD CTD missi :Disso n:Dis cence: :Bottle ag Dissolv n:Dis ag !Numb ~u ~u vity: lved: solve CTD: ~o ed: ~ed:B ~o !er mb en CTD CTD: d:CTD Seapoin tt Bottle: ottle tt ! er ce Volume :Mass t le Volume :Mass le !---- -- -- ------ -------- -------- -------- ----- ------ ----- ------- -------- -- ------- ----- -- *END OF HEADER 312 2 2 2.8 5.4011 32.6178 25.7675 60.7 7.18 312.6 0.560 32.6191 0 7.153 311.3 6 311 1 1 4.6 5.4007 32.6186 25.7682 60.8 7.18 312.3 0.570 32.6201 0 7.170 312.1 36
