Paper Abstract

We have investigated the effects of a phytoplankton model of an area in the Barents Sea subject to different ways of specifying the light field. Three different schemes is used to calculate the light available for photosynthesis, (1) non-spectral attenuation of light in the water column, (2) spectral attenuation, and (3) calculating the photosynthetic usable radiation from the spectral scheme. This study also investigates the effects of changes in the spectral distribution under a cloudy sky with an increase in the shortwave radiation and a decrease in radiation at longer wavelengths.
