摘要

A depth and time resolved primary productivity model is proposed and validated with in-situ and simulated-in-situ incubations using ~(13)C in the western Pacific Ocean. In this model, a vertical distribution of photosynthetically available radiation (PAR) is modeled based on the chlorophyll-a concentration in the surface layer, where the assumption that the surface chlorophyll a concentration determines the light field. A vertical distribution of chlorophyll a concentration is modeled with an empirical equation, in which a chlorophyll maximum is observed along the vertical distribution of PAR. A carbon fixation rate is modeled as a function of PAR and temperature, in contrast to previous studies, a temperature dependent function is significantly improved. With finding an optimum vertical distribution of PAR for various combination of chlorophyll a concentration and diffused attenuation coefficient, our depth and time resolved primary productivity model exhibited a good correlation with in-situ and simulated-in-situ incubation.
