Image Caption: Trichodesmium plankton bloom Trichodesmium plankton blooms are not as
apparent as the bright blue of the coccolithophor blooms but have
been documented just as often. Extensive filaments of this type of
plankton bloom have been photographed off the Western, Northern and
Eastern coasts of Australia. This phenomena has not been easily
detectable with other sensors such as the color zone coastal scanner
(CZCS) or Advanced Very High Resolution Radiometer (AVHRR). First using
Shuttle photography to detect Trichodesmium erythraeum phytoplankton
blooms, Ajit Subramaniam, Marine Sciences Research Center, State
University of New York Stony Brook, was then able to extract data from
specific areas from the CZCS data to build an algorithm to detect these
plankton blooms in other regions of the world from the CZCS data. Since
plankton use carbon, this type of information adds to the understanding
of the processes and quantity of carbon which the oceans can absorb.
