years. It may be that we are only keeping
up with the amount of pollution we are producing. (Knopman, 1993)
The early biosphere was not pleasant for life because the atmosphere had
low levels of oxygen. Photosynthetic bacteria consumed carbon dioxide and
produced simple sugars and oxygen which created the oxygen abundant atmosphere
in which more advanced life forms could develop. (Brown, 1994) The mystery of
how Earth's oxygen levels rose is very complex. Scientists don't agree when or
how the oxygen on earth got here, but we know we could not live without it.
(Pendick, 1993) Oxygen is crucial for humans to survive. Dissolved oxygen is
also crucial for most fish and aquatic organisms to survive. Dissolved oxygen
is for them what atmospheric oxygen is for humans. If humans have no oxygen to

1992)

pressure or atmospheric oxygen concentration goes up, the
level of dissolved oxygen goes up. (Roskowski & Marshall, 1993) D.H. Farmer
studied the fluctuation of dissolved oxygen content in a body of water before,
during, and after a storm. During the storm, the increased wave activity
increased the dissolved oxygen content. (Farmer and McNeil, 1993)
Turbulent flow in streams has caused most of the biocenogenesis (the
environmentally determined characteristics of an organisms) to be represented by
attached or benthic organisms. For this reason, a method of evaluating the role
of benthic organisms in the total dissolved oxygen balance was created. Benthic
plants play an important ...
