  Notes: na = Geotraces number or Event # was not assigned to this sample;  
   All samples except Event 16 involved a rinse of the funnel/bucket using DI water and subsequent collection of that rinse.  
   This was either because of low (or no) sample volume, or in a couple of cases, to help melt snow that had accumulated in the funnel.  
   DIW rinse volume used was always 100ml. Total volume is approximate and based on measurement of sample/rinse volume from the other bucket.
