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 109.4 x top edge, end 109.4 x 13.9 Much dirt and fragmented diatoms-- difficult counting small, finely striated Nitzschia: I am not sure that these are different, but I split them based on the presence or absence of a visible central nodule-- N. paleacea and N. cf. archibaldii. Both of these would probably have been called N. kuetzingiana by NAR.
