Ocean products
- For evaluation of
global ocean biomass and primary production
It is very difficult
to detect long-term trends of ocean biomass since it varies widely over
a short time. It is important to produce a long yet accurate time series
of ocean color datasets generated from CZCS, SeaWiFS, OCTS and GLI
sensors. Those retrieval results, along with observations from ships and
buoys, will be used as key input parameters to biogeochemical cycle
models to improve our knowledge of the ocean carbon cycle.
- There are many species of phyotoplankton in the ocean, each
of which plays a different biogeochemical role in the ocean environment.
Carefully allocated ocean color channels of GLI will be useful in
identifying these species of phytoplankton. Ocean color channels also
will be useful in evaluating the biomass around continental shelves
where the optical properties are complicated due to complex
environmental conditions affected by river runoff. Both accurate
estimation of the chlorophyll-a amount and the distribution of land
origin substances, such as suspended matter and dissolved organic
matter, should be possible by analyzing GLI ocean color data
sets.
