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: Row 1 x 38.5, y 88; y 102; Row 2 x 37.5, y 102; y 86; Row 3 x 36, y 86; y 102. Sample very sparse. Only about 30-40 valves per transect (1/2h per transect). Thus, it would require more than 4 h to reach a count of 600 valves. No additional species found.
