Deep maxima of several species of phytoplankton were found to occur in the metalimnion of Lake D. Helvecio, during a period of strong thermal stratification, at depths receiving very low intensities of incident radiation.
The vertical distributions of 14C assimilation and of the photosynthetic pigment, chlorophyll a, were investigated to explain the possible causes for the metalimnetic accumulation of biomass.
