The salinity, temperature and transmissivity data reported is from the corrected and calibrated downcast ctd data. Dissolved oxygen concentrations were determined using an automated titration system consisting of a Brinkman Dosimat (model 665) and a PC 900 Colorimeter. Nutrients were measured using an Autoanalyzer II, following the procedures outlined in 'Institute of Ocean Sciences Nutrient Methods and Analysis, Barwell-Clarke and Whitney, 1997'. The samples were frozen on board and brought back to IOS for analysis. Nitrate/silicate samples were defrosted for about 24 h before analysis and phosphate samples were rapidly defrosted in moving room temperature air or warm water. See file 9805nutr.xls for details on the analysis, turbidity corrections and calibration. The 0 and 10 m samples for all stations (N/Si and P tubes) were centrifuged at 3500 rpm for 15 min before analysis to eliminate interference from particulates. Turbidity corrections for phosphate were made for samples 27 (NI07 0m 23.5o/oo) and 37 (NI06 0m 24 o\oo), using a previously determined correction for salinity (Georgia Strait Cruise 9725). Neither replicate of sample # 95 was shaken prior to analysis, and therefore the data are considered of very poor quality and have been removed from the archived data. A total of 178 samples were measured; of these, 22 samples were measured in duplicate to estimate variability and the pooled standard deviations are as follows: Nitrate Sp=0.43 uM; Silicate Sp=0.92 uM; Phosphate Sp=0.045 uM. *INSTRUMENT $REMARKS Comments from secondary file: c:\data_D\temp\9805\98050005.dwn -------------------------------------------------------------- Acquisition program : CTD.EXE version 1.45 CTD data type : 2 ! 8755 system binary frame Control String : KP3000TC4 $END !--1--- -2-- ---3---- --4-- ---5--- ---6---- ---7---- --8-- !Pressu Samp Salinity Oxyge Oxygen: Salinity Temperat Trans !re le_ :Bottle n: Dissolv ure missi !
