Determination of CTD data at bottle stops: Method of determination reviewed in December 2003 by Sarah Zimmermann. Data are from the downcast Guildline CTD, found by matching the SBE-19 upcast bottle trip pressures to the Guildline after correcting for the SBE-19 surface offset (1 to 2 db depending on station), sensor to bottle center offset (-0.6 db), and an additional offset of +0.2db. [Performed by Julie Bacle and Humfrey Melling] It was determined by looking at the CTD and bottle salinities that no further offset was required to correct for the bottle flushing and fluid dynamics around the package. [Performed by Sarah Zimmermann] The listed pressures are the applied corrections. Note : Some stations (FT1, FT3, BS2, BS3-test, JR1,JR4, JRL4, EI9, CI1) were missing SBE-19 bottle trip pressures. For these stations, the Guildline CTD data were found by taking the records where bottle salinities matched the CTD salinities. The nature of this method already accounts for the pressure offsets, thus no further corrections were required. [Performed by Mary O’Brien] Note : There are still some question Regarding CTD Salinity Calibration : Five stations (87, 88, 89, 91 and 92) show a 0.01 difference between CTD and bottles in the high salinity, deep water. See file report_199924_ctdbottlestopdata.doc for more detail. Temperature and bottle salinities at the bottle trip depths are included : Temperature_ITS68 and Salinity_PSS-78 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=0.07 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 were analyzed by The 'Stable Isotope Laboratory' at the University of Calgary as described in the file : UofC_O18_analysis_description.doc The 18O/16O ratio was determined using the common CO2-H2O equilibration technique (Epstein, 1953; O'Neil et al., 1975) in which millimole quantities of CO2 are equilibrated with water samples under constant temperatures. Subsequently, the CO2 is cryogenically purified and analyzed mass spectrometrically for its 18O/16O ratio. Note that this technique measures the isotopic activity of 18O and not the actual 18O concentration. For dilute waters, differences between isotopic activity and concentration are negligible. For saline waters and brines, however, supplemental water chemistry data and longer equilibration times are needed to obtain true isotopic compositions (Horita, 1993; Sofer, 1972). CFC Measurements (analyst: Nes Sutherland) CFC analysis was carried out on the IOS automated purge and trap system. Separation and detection of the components was achieved using a 60 m, 0.32 mm GasPro Gas separator fused silica column and a Hewlett Packard GC/Electron Capture Detector. Standardization was done using a gas standard (S14) made at Brookhaven National Laboratories and standardized at Scripps Institute of Oceanography according to the SIO1993 scale. Analyses for CFC12, CFC11, CFC113, and CCl4 was carried out. Air samples were taken as a further check on the operation of the system. All concentrations are reported in picomoles/litre. Note : the Methylene_chloride data is not calibrated to reference standards. !-1-- --2--- ---3--- ---4--- ---5--- --6--- !Samp Pressu Salinit Tempera Salinit Oxygen !le_ re y: ture y : !Numb Bottle Isotop !er e:18 !---- ------ ------- ------- ------- ------ *END OF HEADER 95 3.0 25.459 2.071 25.392 -4.59
