Satellite observation is a powerful tool for estimating primary
production. However, in situ bio-optical properties, which determine
the ocean-color associated with productivity levels in satellite
images, have been largely unknown in this region. Takao
et al. (2014) evaluated for the first time the bio-optical properties
of chlorophyll a concentration, the light absorption coefficients of
phytoplankton, non-arboreal pollen, and colored dissolved organic
matter (CDOM), as well as the spectral diffuse attenuation coefficient
and remote sensing reflectance in the Sea of Okhotsk. They
report that in this region, optical absorption is generally dominated
by CDOM or phytoplankton absorption at all wavelengths, and
they reveal that CDOM-rich waters originating from the Amur
River significantly affect the performance of operational global
algorithms for determining chlorophyll a concentration in the
Sea of Okhotsk.
