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--- !Samp Pressu Salinit Oxygen: Tempera Salinit !le_ re y: Dissolv ture y !Numb Bottle ed !er !---- ------ ------- ------- ------- ------- *END OF HEADER 222 5.9 27.421 7.571 4.271 27.213 221 10.7 27.583 7.616 4.679 27.446 220 15.5 27.927 7.621 4.852 27.697 219 20.8 29.943 7.771 4.805 28.600 218 30.9 30.742 7.849 3.250 30.823 217 41.1 31.443 8.076 1.959 31.474
