| Outline of Final Research Achievements |
A satellite remote sensing algorithm was developed to estimate the group-specific primary production of marine phytoplankton. A novelty of the algorithm is that it integrates bio-optical modeling with image processing. Analysis of the 10-year long satellite data of the group-specific primary production obtained from the new algorithm showed that 1) the photosynthetic rate is different among the groups and 2) factors affecting variability of the photosynthetic rate also differ among the groups: the photosynthetic rate of diatoms are mainly regulated by their biomass, whereas that of cyanobacteria by photo-physiology. The rate of haptophytes are affected by both their biomass and photo-physiology, depending on season/months in consideration.
