The pressures of the bottles tr are also from the uncorrected upcast data. note : November 18, 1999 - Changes made to chemistry files for casts 80 to 108 : In order to bring this data into line with the rest of the Georgia Strait cruise the uncorrected upcast salinities and temperatures were delieted using the REMOV program and replaced with the downcast salinities and temperatures by using the MERGE program. The remainder of the files for this cruise have uncorrected and uncalibrated temperatures in them as recorded in the .hyd files. 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. An alcohol bath was used to freeze the samples and it was noted that some samples smelled of alcohol. 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 9742nutr.xls for details on the analysis, turbidity corrections and calibration. total of 164 samples were measured; of these, 34 samples were measured in duplicate to estimate variability and the pooled standard deviations are as follows: Nitrate Sp=0.41 uM; Silicate Sp=1.23 uM (Note that Si variability is higher than usual); Phosphate Sp=0.066 uM .
