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 41, y 89; y 100; Row 2 x 40, y 100; y 89; Row 3 x 39, y 89; y 100; Row 4 x 38, y 100; y 89; Row 5 x 37; y 89; y 100 Sparse sample. Count of 600 will not be reached at the end of four hours. I already spent close two 3 hours to reach a count of 326. I went over 100 valves because there were about 60 valves in first transect and I hoped there were going to be more in subsequent transects, but number just went down.
