Phytoplankton community adaptation to changing light levels in the southern Beaufort Sea, Canadian Arctic
International audience The chlorophyll a specific absorption coefficient of phytoplankton, a(phi)*(lambda) is an important parameter to determine for primary production models and for the estimation of phytoplankton physiological condition. Knowledge of this parameter at high latitudes where nutrien...

International audience The chlorophyll a specific absorption coefficient of phytoplankton, a(phi)*(lambda) is an important parameter to determine for primary production models and for the estimation of phytoplankton physiological condition.
