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 x33.5, y85.4; y94.3 row 2 x34; y91.6. Difficult taxonomy on this slide. Many looked similar to the A. exilis from other slides in this study unit. However, some look closer to A. thermalis. Some of the Gomphonema gracile specimens had pinched apices -- maybe a different designation is appropriate. Interesting slide.
