Phytoplankton Observations
Challenge and Treated
1. A very diverse population was observed containing the 17 species already noted.
2. The dominant species was the diatom
Skeletonema
with long chains of 14-16 cells.
3.
Prorocentrum
, the dominant dinoflagellate, caused a brown coloration in the water.
Treated (post-filter)
1. Numbers were noticeably reduced in the treated samples.
2. Although the majority of the larger species were removed, many in the 30 µm range were
noted in the treated sample.
