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: start x=91.0, y=17.0; end x=91.0, y=20.7 Counted only the left half of the last field of view to reach 600. Observed species (= seen while qualitatively scanning the slide but not encountered during the 600 valves count): Gomphonema aff. lagenula Kützing narrow Observations on individual taxa: - In the counts I kept separated the morphotype corresponding to Navicula minima Grunow in Vaan Heurck (Figs 128-142 in Wetzel et al. 2015) from "typical" Sellaphora saugerresii (e.g., Figs 112-127 in Wetzel et al. 2015). In this count: Sellaphora saugerresii "typical" = 2 valves Morphotype Navicula minima = 8
