3 QUALIFIERS:

  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: 300 natural units with diatoms counted in 43 fields of view Transect 1x142.5,y24.5,y7.4=17.1 mm Transect 2x142,y7.3,y13.3=6 mm, total 23.1 mm/0.54mm=43 filds of view 300 natural units of soft algae counted in a total 150 fields of view transect 2 cont. x142,y13.3,y24.6=11.3mm Transect 3x141.5,y24.6,y7.5=17.1mm Transect 4x140.4,y7.5,y23.7=16.2 mm Transect 5x139.8,y22.8,y9.6=13.2mm additional 57.8 mmscanned for 107 fields of view (43 +107=150 total fields of view scanned)

  Qualifier Code: was5ct
  Description: changed count code from 5 to 1, and made count official
  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
