1 QUALIFIER:

  Qualifier Code: TaxaNote
  Description: Notes taken about the taxa for a count; older data typically includes information such as beginning and end scan coordinates, unusual taxa, etc.
  Comments: Row 1 x101, y7.8; y24.9; Row 2 x100, y7.8; y14.8 Slide is silty and contains many broken diatom pieces. Some diatoms looked as if they had been overdigested. These factors made it difficult to identify diatoms on the slide. Therefore the count was terminated after more than four hours with a count of 405 completed. Navicula veneta looked slightly different in valve shape than usual.
