Samples Number 85 and 93: Salinity:Bottle - 2 values differed signficantly; no 3rd run. Sample Number 87: Salinity:Bottle - outlier in COMPARE. Analysis methods: ----------------- Chlorophyll samples were analyzed at sea using a Chemistry Turner Designs fluorometer which was calibrated in May 2008 using pure chlorophyll a. 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 !Samp Bo Pressu Temperat Salinity Sigma-t: Trans Oxygen Oxyge Fluores Salinity Fl !le_ tt re:CTD ure:CTD :CTD CTD missi :Disso n:Dis cence: :Bottle ag !Numb ~u vity: lved: solve CTD ~o !er mb CTD CTD: d:CTD tt ! er Volume :Mass le !---- -- ------ -------- -------- -------- ----- ------ ----- ------- -------- -- *END OF HEADER 98 24 5.1 11.2717 31.9793 24.4023 36.7 7.47 325.5 1.897 31.9972 3 97 23 10.3 9.4491 32.0411 24.7575 42.5 7.45 324.5 2.446 32.0581 3 96 22 10.1 9.5071 32.0357 24.7441 42.4 7.43 323.7 2.343 -99.0000 95 21 10.4 9.4729 32.0376 24.7510 42.4 7.44 324.2 2.332 32.0522 3 94 20 10.2 9.5138 32.0353 24.7427 42.6 7.45 324.4 2.356 32.0484 3 93 19 499.8 5.1196 34.1299 26.9975 59.4 0.60 25.9 0.082 34.1281 4 92 18 499.9 5.1196 34.1299 26.9975 59.5 0.60 25.9 0.081 34.1266 3 91 17 499.8 5.1196 34.1299 26.9975 59.3 0.60 25.9 0.084 34.1264 3 90 16 499.8 5.1195 34.1300 26.9975 59.5 0.60 25.9 0.083 34.1263 3 89 15 499.8 5.1194 34.1299 26.9975 59.5 0.60 25.9 0.081 34.1274 3 88 14 499.8 5.1193 34.1299 26.9975 59.5 0.60 25.9 0.081 34.1270 3 87 13 599.7 4.7522 34.1915 27.0881 59.0 0.38 16.7 0.083 34.1269 3 86 12 1000.6 3.6601 34.3849 27.3570 59.0 0.26 11.2 0.084 34.3817 3 85 11 1000.4 3.6599 34.3849 27.3570 59.0 0.26 11.2 0.084 34.3833 4 84 10 1000.8 3.6601 34.3848 27.3569 59.0 0.26 11.2 0.084 34.3825 3 83 9 1000.3 3.6600 34.3849 27.3570 59.0 0.26 11.2 0.082 34.3810 3 82 8 1000.6 3.6601 34.3848 27.3569 59.0 0.26 11.2 0.083 34.3843 3 81 7 1000.1 3.6598 34.3849 27.3571 59.0 0.26 11.2 0.084 34.3842 3 80 6 1322.0 3.0828 34.4617 27.4735 58.6 0.42 18.3 0.088 34.4622 3 79 5 1322.4 3.0826 34.4619 27.4737 58.6 0.42 18.3 0.088 34.4613 3 78 4 1322.1 3.0828 34.4618 27.4736 58.6 0.42 18.3 0.087 34.4621 3 77 3 1322.4 3.0808 34.4621 27.4740 58.5 0.42 18.3 0.086 34.4590 3 76 2 1322.2 3.0789 34.4624 27.4744 58.5 0.42 18.3 0.087 34.4592 3 75 1 1322.2 3.0787 34.4624 27.4745 58.5 0.42 18.3 0.086 34.4603 3
