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 x 108, y 3, y 16. Only 32 valves were counted in 45 minutes of analysis. There are large sediment particles in the sample, but only a few broken valves. Perhaps diatoms are naturally in low abundance at the site. Continued count: Row 2 x 106, y 17, y 2, Row 3 x 105, y 2, y 17, Row 4, x 104, y 17, y 2, Row 5 x 102, y 2, y 17, Row 6 x 101, y 17, y 2. Sparse sample, only 124 valves found after 4 hours of analysis.
