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-- !Samp Bo Pressu Temperat Salinity Sigma-t: Trans Oxygen Oxyge Fluores !le_ tt re:CTD ure:CTD :CTD CTD missi :Disso n:Dis cence: !Numb ~u vity: lved: solve CTD: !er mb CTD CTD: d:CTD Seapoin ! er Volume :Mass t !---- -- ------ -------- -------- -------- ----- ------ ----- ------- *END OF HEADER 215 16 8.6 5.9818 32.5293 25.6287 57.3 6.98 303.8 0.789 214 15 10.6 5.9812 32.5293 25.6288 57.3 6.98 303.8 0.765 213 14 8.7 5.9830 32.5293 25.6286 57.3 6.99 304.0 0.794 212 13 9.6 5.9831 32.5292 25.6285 57.3 6.98 303.9 0.764 211 12 502.2 3.9910 34.0809 27.0817 61.5 0.74 32.1 0.123 210 11 500.0 3.9918 34.0806 27.0814 61.4 0.74 32.1 0.122 209 10 502.2 3.9908 34.0808 27.0817 61.5 0.74 32.1 0.123 208 9 501.1 3.9917 34.0807 27.0815 61.5 0.74 32.1 0.122 207 8 1001.2 3.0119 34.3626 27.4009 61.4 0.30 12.9 0.118 206 7 1000.8 3.0125 34.3625 27.4008 61.4 0.30 12.9 0.119 205 6 1000.8 3.0131 34.3625 27.4007 61.4 0.30 12.9 0.119 204 5 1000.2 3.0133 34.3625 27.4007 61.4 0.30 12.9 0.118 203 4 2000.9 1.9261 34.5886 27.6736 61.6 1.32 57.4 0.111 202 3 2000.9 1.9260 34.5887 27.6737 61.6 1.32 57.4 0.111 201 2 1999.9 1.9259 34.5886 27.6736 61.6 1.32 57.4 0.113 200 1 2001.5 1.9261 34.5887 27.6737 61.6 1.32 57.4 0.113
