Upon a short period of very extensive
research, one can conclude many things about the
phytoplankton content of the waters surrounding the
continent of Antarctica.First of all, what is
phytoplankton? Phytoplankton is defined as
planktonic plants and other autotrophs which are
the most important primary producers in many marine
ecosystems. (p. 213 Castro-Huber) Many factors
influence the growth of phytoplankton such as
sunlight, water temperature, and water current.
In my specific study of the pytoplankton
present in Antarctic waters, I discovered a most
unusual pattern of growth: only on three occasions
from September 1997 to March 2000 was phytoplankton
present in the waters of Antarctica. Of the three
individual times that phytoplankton was present in
the water, two of these occured in December 1998
and 1999, the other in September 1998. Every other
month from September 1997 until March 2000, the
waters contained a phytoplankton reading of 0
(zero). The only conclusion that can be made
about the numerous occasions in which phytoplankton
was absent from the waters is that massive sheets
of ice cover the water around the continent of
Antarctia making unacceptable conditions for the
