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 2, y 15. Only 100 valves counted after 45 min of analysis. Most of the diatom material is just fragments and partially dissolved valves. No images were taken. Continued count: Row 2 x 107, y 17, y 2, Row 3 x 106, y 2, y 17, Row 4 x 105, y 17, y 2, Row 5 x 104, y 2, y 17. Sparse sample with lots of fragmented diatoms...difficult to count.
