growth_limitation_of_diatoms_due_to_solar_irradiance 1 [UUUU] "Irradiance" means the power per unit area (called radiative flux in other standard names), the area being normal to the direction of flow of the radiant energy. Phytoplankton are autotrophic prokaryotic or eukaryotic algae that live near the water surface where there is sufficient light to support photosynthesis. Diatoms are single-celled phytoplankton with an external skeleton made of silica.
