  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 x100, y8; y18.6 Added a new taxa: Navicula sp. 49 NAWQA HAGAN. The diatom looks very similar to Naviculadicta sassiana but it is 3um wide instead of 4.5-5um. Would have added it as a Naviculadicta cf if that genus was used. This slide had a large amount of sediment which made clearly seeing and identifying diatoms correctly. There were broken pieces of diatoms present.
