Dissolved Oxygen : Analyzed onboard the CCGS Sir wilfrid Laurier by Mary O'Brien using an automated version of the Micro-Winkler Technique as described in : "Carpenter, J. H., 1965. The Chesapeake Bay Institute technique for the " "Winkler dissolved oxygen method, Limnol. Oceanogr., 10, 141-3. " The titration is done using a Metrohn Dosimat 665 and the end point is detected using a Brinkmann probe colorimeter PC900. The methodology is described by an internal OSAP document (Dissolved Oxygen Determination Methods and Procedures by Bernard Minkley and George Chase). Standard pooled deviation for 26 duplicates for the oxygen analysis is 0.034 mL/L. Range for all data is 5.2 to 10.3 mL/L "note - only the first of the duplicates is included in the archived data ie, no averaged data for dissolved oxygen is included in the archive. Bottle salinities : Samples were brought back to IOS and analyzed using a Portasal (model 8410; Serial number 59724) which was standardized using IAPSO standard seawater (batch P134). Analysis done by Doug Sieberg. No duplicate samples were taken. "Nutrients : (silicate, nitrate plus nitrite and orthophosphate)" Samples were analyzed onboard by Janet Barwell-clarke. Nutrients were analyzed using Technicon Autoanalyzer II components. Reactive silicate and nitrate plus nitrite were determined according to " Technicon Industrial Methods No. 186-71 W and 158-71 W respectively, and" soluble orthophosphate was determined using a modified Technicon method "as described in : Brynjolfson, S.J., 1973. A modification of the Technicon" "methodology for the determination of orthophosphate in seawater, " "Paper presented at Water Resources Services, Vancouver, B.C." "The method is also described in an internal document : ""Institute of Ocean " "Sciences Nutrient Methods and Analysis"" by J. Barwell-Clarke and F Whitney " 1996. Most of the samples were analyzed in duplicate and pooled standard deviations were calculated as follows : Silicate: 69 samples were analyzed in duplicate "Pooled standard deviation for 699 pairs : Sp=0.203 umol/L, n=69 " (range for all data is 2.1 to 46.0 umol/L) Archived data is the average of the duplicates. Orthophosphate: 36 samples were analyzed in duplicate "Pooled standard deviation for 36 pairs : Sp=0.034 umol/L, n=36 " (range for all data is 0.0 to 1.9 umol/L) Archived data is the average of the duplicates. Nitrate plus Nitrite: 69 samples were analyzed in duplicate "Pooled standard deviation for 69 pairs: Sp=0.0.07 umol/L, n=69 " (range for all data is 0.0 to 17.0 umol/L) Archived data is the average of the duplicates. Oxygen isotopes : samples taken and analyzed but not available - contact Fiona McLaughlin Samples were analyzed by The 'Stable Isotope Laboratory' at the University of Calgary using the CO2-H2) equilibration technique as described in the file : o18 analysis description.doc Temperature and bottle salinities at the bottle trip depths are included : Temperature_ITS68 and Salinity_PSS-78 CFC data analyzed but not avalable - contact Fiona McLaughlin for information. Barium samples were taken - contact Fiona McLaughlin for information. !-1-- --2--- ---3--- ---4--- --5-- --6-- --7--- ---8--- ---9--- !Samp Pressu Salinit Oxygen: Nitra Silic Phosph Tempera Salinit !le_ re y: Dissolv te_ ate ate ture y !Numb Bottle ed plus_ !er Nitri ! te !---- ------ ------- ------- ----- ----- ------ ------- ------- *END OF HEADER 243 5.5 30.396 7.459 0.0 4.4 0.54 5.188 30.374 242 10.5 30.446 7.524 0.0 4.5 0.58 5.161 30.384 241 50.4 32.517 7.231 8.8 18.4 1.31 -1.323 32.539 240 100.3 32.874 6.296 13.2 28.2 1.59 -1.435 32.872 239 125.5 33.046 6.121 14.6 30.1 1.63 -1.413 33.056 238 175.5 33.556 5.744 16.2 32.8 1.64 -1.149 33.563 237 400.2 34.731 5.492 15.6 24.6 1.08 0.181 34.727 236 450.3 34.734 5.563 15.4 24.2 1.06 0.207 34.744 235 500.0 34.739 5.640 15.4 23.7 1.05 0.221 34.751 234 550.1 34.751 5.651 15.2 23.8 1.03 0.234 34.759 233 600.2 34.744 5.677 15.2 24.0 1.03 0.239 34.761 232 640.7 -99.000 -99.000 -99.0 -99.0 -99.00 0.244 34.763
