Abstract

Recent advances in ocean remote sensing have made it possible to study various aspects of ocean biogeochemistry from satellite data. This presentation will deal with the applications of remote sensing for understanding the biomass and dynamics of the marine autotrophs, which are responsible for almost half of the annual global carbon fixation, and is fundamental to the global carbon cycle. The presentation will include recent results on developing ocean-colour algorithms, and implementation of data assimilation using biogeochemical models towards accurate estimation of autotrophic biomass stocks, and for better understanding of the autotrophic dynamics on a global scale. Limitations of the current approaches and opportunities for future development will be discussed in the context of minimising uncertainties in satellite-derived estimates, through algorithms and marine ecosystem models.
