We propose a bio-optical inversion model that retrieves the absorption contributions of phytoplankton and colored detrital matter (CDM)
as well as the phytoplankton size classes (PSCs)
from total minus water absorption spectra. The model is based on three-component separation of phytoplankton size structure and a genetic algorithm. The model performance was tested on two independent datasets (the NASA bio-Optical Marine Algorithm Dataset (NOMAD) and the northern South China Sea (NSCS) dataset). The relationships between the estimated and measured values were strongly linear
especially for a CDM (412)
and the Root Mean Square Error (RMSE) of the CDM exponential slope (S CDM) was relatively low. Next
the inversion model was directly applied to in-situ total minus water absorption spectra determined by an underwater meter during a cruise in September 2008
to retrieve the phytoplankton size structure in the seawater. By comparing the measured and retrieved chlorophyll a concentrations
we demonstrated that total and size-specific chlorophyll a concentrations could be retrieved by the model with relatively high accuracy. Finally
we applied the bio-optical inversion model to investigate changes in phytoplankton size structure induced by an anti-cyclonic eddy in the NSCS.
