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=96.5, y=18.0; end x=96.5, y=15.0 Counted only the left half of the last field of view to reach but not exceed too much the 600 valves target. Observed taxa: Nitzschia amphibia Observations on individual taxa: - Nitzschia palea SHORT SUBCAPITATE = 53 valves Nitzschia palea = 4 (detailed explanation in count note of sample NEON00323) - In the counts I kept separated the morphotype corresponding to Navicula minima Grunow in Van 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" = 12 valves Morphotype Navicula minima = 6 Nomenclatural updates (with respect to the ANSP 2011 list): Gomphonema parvulum: This is a species complex.
