Figure 4. 12% salinity column
Figure 5. All columns from 0% (left) to 12% (right). The column on the left has cyanobacteria growing even on the plastic wrap. Condensation obscures the view, but there is some floating matter on the other columns.

Week of October 8th
This week, the most notable change to the Winogradsky columns was the dramatic growth of the cyanobacteria in the 0% salinity column. The other columns have had little change, but the 4% column is beginning to show clearer signs of stratification. Because the first column has had such dramatic growth of cyanobacteria, it might actually obscure other layers, preventing us from counting them in the future. Hopefully other layers will grow enough to be clearly visible.
