  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 x103, y8; y14.1 This slide had a lot of sediment and very few diatoms. This made finding and determining the specific taxon of diatoms difficult. In general, though the condition of the diatom frustules was good and there were no broken valves present. A count of 100 valves took over four hours therefore the count was suspended at this point.
