    •  In marine ecosystems, the size structure of phytoplankton is one of the factors that determine the energy transfer efficiency in the food web. Therefore, spatiotemporal monitoring of the wide-range phytoplankton-size structure is important for evaluating changes in the marine ecosystem. Based on previous studies, the light absorption spectrum is known to differ depending on the size and group of phytoplankton. Therefore, we designed a method to estimate the phytoplankton-size structure based on the light absorption spectrum.
