Chlorophyll precision was determined by analyzing replicate samples drawn from one Niskin. For details see file 2008-26_CHL.pdf. 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 duplicate analysis see file 2008-26_OXY.pdf. 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 2008-26_SAL.pdf for information on precision, and note the warning given below. 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 2008-26_NUT.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 2008-26_DMS_report.pdf. For duplicates analysis see file 2008-26_DMS.pdf. References: 1. Carpenter, J.H. 1965.

Many duplicate samples were run using an Autosal at IOS and the Portasal. The results showed that the Portasal read much lower than the Autosal for those samples analyzed on the Portasal on June 5th. For other days the Portasal was low by an average of 0.0016 but there was a lot of noise in the comparison with many values within 0.001 of the Autosal, while others looked unstable. Autosal values have been selected for Salinity:Bottle where possible. Where there are no Autosal values, the Portasal values were used, but were all flagged 3, except for those from June 5th which have been flagged 4. ********************************************************************************** Transmissivity, fluorescence and PAR are nominal and unedited except that some records were removed in editing temperature and salinity. The Salinity:Practical:CTD data were recalibrated based on a comparison with samples analyzed at IOS on an Autosal. Other samples run at sea on a Portasal appear unreliable based on a study of duplictes run on the two salinometers. For details on the processing see processing report: 2008-26-proc.pdf $REMARKS Data quality is expressed with the following flags ---------------------------------------------------------------------------- 1 = Sample for this measurement was drawn from water bottle but not analyzed (not normally used). 2 = Acceptable measurement (not normally used). 3 = Questionable measurement (no problem observed in sampling or analysis, but value is not trusted, nonetheless; includes outlyers). 4 = Bad measurement (known problem with sampling or analysis, but not serious enough to completely discard the value). 5 = Not reported (lost sample; unredeemably bad measurement). 6 = Mean of replicate measurements. 7 = Manual chromatographic peak measurement. 8 = Irregular digital chromatographic peak integration. 9 = Sample not drawn for this measurement from this bottle (not normally used). ---------------------------------------------------------------------------- $END !-1-- 2- --3--- ---4---- ---5---- ---6---- --7-- --8--- --9-- ---10-- --11-- --12- 13 --14-- 15 --16- 17 --18-- 19 --20-- 21 !Samp Bo Pressu Temperat Salinity Sigma-t: Trans Oxygen Oxyge Fluores PAR: Nitra Fl Phosph Fl Silic Fl Chloro Fl Dimeth Fl !le_ tt re:CTD ure:CTD :CTD CTD missi :Disso n:Dis cence: CTD te_pl ag ate: ag ate: ag phyll: ag yl_ ag !Numb ~u vity: lved: solve CTD ~Nitr ~o Bottle ~o Bottl ~o Extrac ~o Sulphi ~o !er mb CTD CTD: d:CTD ite:B tt tt e tt ted: tt de: tt ! er Volume :Mass ottle le le le Bottle le Bottle le !---- -- ------ -------- -------- -------- ----- ------ ----- ------- ------ ----- -- ------ -- ----- -- ------ -- ------ -- *END OF HEADER 55 17 2.8 11.5198 31.9841 24.3616 35.6 7.35 320.2 1.322 274.0 -99.0 9 -99.00 9 -99.0 9 1.63 2.50 54 16 5.2 11.4856 31.9852 24.3686 36.1 7.36 320.8 1.468 177.0 -99.0 -99.00 -99.0 -99.00 -99.00 53 15 5.1 11.4717 31.9856 24.3714 35.9 7.37 321.4 1.491 180.6 -99.0 -99.00 -99.0 -99.00 -99.00 52 14 5.2 11.4560 31.9874 24.3757 36.1 7.37 321.2 1.515 179.5 1.0 0.42 5.7 1.54 2.32 51 13 10.4 10.2377 32.0047 24.6005 37.4 7.80 340.0 3.155 76.4 -99.0 -99.00 -99.0 -99.00 -99.00 50 12 10.4 10.2328 32.0028 24.5998 37.6 7.83 341.2 3.166 77.6 0.6 0.39 4.7 2.27 1.90 49 11 15.0 9.4035 32.0975 24.8089 40.2 7.82 340.5 3.052 35.6 1.1 0.44 5.8 2.27 1.59 48 10 20.1 8.9966 32.1385 24.9046 46.4 7.22 314.4 1.659 16.3 3.2 0.59 7.0 1.59 1.30 6 47 9 25.2 8.8778 32.1861 24.9601 45.1 7.34 319.5 2.160 8.4 -99.0 -99.00 -99.0 -99.00 -99.00 46 8 25.1 8.8914 32.1842 24.9566 44.8 7.34 319.6 2.219 8.5 3.2 0.58 6.7 1.76 1.31 45 7 29.7 8.6296 32.2654 25.0600 50.9 7.04 306.7 0.849 4.9 4.7 0.75 7.9 -99.00 9 0.63 44 6 39.7 7.7470 32.4652 25.3457 55.5 7.10 309.1 0.601 2.0 7.3 0.93 10.3 0.34 6 0.37 43 5 49.7 7.3815 32.4883 25.4148 56.6 7.05 307.2 0.417 0.9 8.7 1.00 11.4 0.23 0.33 42 4 75.6 6.9244 32.5943 25.5600 57.9 6.70 291.5 0.211 0.2 12.3 1.15 14.4 0.12 0.25 41 3 99.8 7.1104 32.9897 25.8463 57.9 5.08 221.1 0.111 0.1 20.3 1.60 25.4 0.05 0.20 40 2 175.2 7.0051 33.8821 26.5634 58.8 2.77 120.6 0.074 0.0 32.3 6 2.24 6 44.1 6 -99.00 0.00 39 1 200.6 6.6802 33.9290 26.6442 58.5 2.36 102.6 0.077 0.0 31.8 2.39 50.2 -99.00 0.00
