3 QUALIFIERS:

  Qualifier Code: fr5_6ct
  Description: combined count code 5 and 6 to 1, same slide, and made count official. Count and taxa notes are on the original, uncombined counts.
  Comments: NRSA data prep

  Qualifier Code: mult_up
  Description: In 2008 official soft algal counts (range NRSA0004-0541, and NRSA0582-0586) that also have a 45 count, multiply up undetermined diatoms live (249999) and undetermined diatoms dead (249998) using formula: Total transect (count 1)/total transect (count 45) x total diatoms; this done prior to any calculations.
  Comments: Diatoms multiplied up per Babs Rinkel request Apr 2010

  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: lugols level ok 300 ncunits reached 19 mm total transect length 235.5 mm Sedgewicke Rafter count Macro material found was degrading. Some dead cells also seen of each species found.
