Analysis methods: ----------------- Salinity samples were collected in glass bottles and analyzed on a Guildline model 8400B Autosal or a Guildline Portasal 8410A. Salinometers are standardized with IAPSO standard seawater. See file 2008-001_SAL.pdf for information on precision and duplicates. Oxygen samples were analyzed on an automated Winkler titration system following the procedures of Carpenter (1965). Samples were analyzed at sea using an automated titration system consisting of a Brinkman Dosimat (model 665) and a PC 900 Colorimeter. For details on precision see file 2008-001_OXY.pdf. Nutrient samples were collected in plastic tubes and analyzed fresh at sea using a Technicon AAII autoanalyzer following methods described in Barwell-Clarke and Whitney (1996). For details on nutrient duplicates and precision see file 2008-001_NUT.pdf. Chlorophyll samples were analyzed at sea using a Chemistry Turner Designs fluorometer which was calibrated in May 2007 using pure chlorophyll a. Chlorophyll precision was determined by analyzing replicate samples drawn from one Niskin. For details see file 2008-001_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 2008-001_DMS_report.pdf. For details on duplicates see file 2008-001_DMS.pdf. Dissolved inorganic carbon (DIC) was determined using coulometric analysis. Total alkalinity (Alk) was determined by potentiometric titration. pH on the total hydrogen ion concentration scale was determined photometrically and is reported at 25C and surface pressure. For duplicates and precision of DIC, ALK and pH samples see files 2008-001_DIC.pdf, 2008-001_ALK.pdf, and 2008-001_pH.pdf respectively. HPLC samples were filtered onto 25mm 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 ~2 weeks 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 and Chlide-a. References: 1. Carpenter, J.H. 1965.

Data Processing Notes: ---------------------- WARNING: All samples from Bottles Number 13 to 18 should be treated with care. While the CTD data correspond to the level at which the bottle were fired, in many cases the bottles closed earlier. Notes in the headers of individual files indicate the probable level at which bottles closed, where evidence exists to make that estimate. For details on the processing see processing report: 2008-001-proc.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 !Samp Bo Pressu Temperat Salinity Sigma-t: Trans Oxygen Oxyge Fluores Salinity Fl Oxygen: Fl Nitra Fl Phosph Fl Silic Fl Chloro Fl !le_ tt re:CTD ure:CTD :CTD CTD missi :Disso n:Dis cence: :Bottle ag Dissolv ag te_pl ag ate: ag ate: ag phyll: ag !Numb ~u vity: lved: solve CTD: ~o ed: ~o ~Nitr ~o Bottle ~o Bottl ~o Extrac ~o !er mb CTD CTD: d:CTD Seapoin tt Bottle: tt ite:B tt tt e tt ted: tt ! er Volume :Mass t le Volume le ottle le le le Bottle le !---- -- ------ -------- -------- -------- ----- ------ ----- ------- -------- -- ------- -- ----- -- ------ -- ----- -- ------ -- *END OF HEADER 177 5 5.1 6.1696 32.4811 25.5676 56.5 6.97 303.6 0.773 32.4882 3 -99.000 0 11.9 0 1.22 0 14.9 0 0.43 0 176 4 10.2 6.1735 32.4817 25.5676 57.4 6.96 303.1 0.763 -99.0000 0 6.950 0 11.9 0 1.22 0 14.9 0 0.46 0 175 3 10.9 6.1734 32.4818 25.5677 57.5 6.96 303.1 0.751 -99.0000 0 -99.000 0 -99.0 0 -99.00 0 -99.0 0 -99.00 0 174 2 10.7 6.1736 32.4816 25.5675 57.4 6.96 303.0 0.760 -99.0000 0 -99.000 0 -99.0 0 -99.00 0 -99.0 0 -99.00 0 173 1 10.0 6.1730 32.4816 25.5676 57.4 6.96 303.1 0.771 -99.0000 0 -99.000 0 -99.0 0 -99.00 0 -99.0 0 -99.00 0
