Abnormally high chlorophyll values have been observed in the deep layer of the Saguenay Fjord, Québec, Canada. Experiments were conducted to assess the capability of this darkened phytoplankton to photosynthetize upon reillumination. It was found that photosynthetic capacity is well retained by deep phytoplankton of the Saguenay, as shown by relatively high production rates, a low tidal variability of these rates and very high P : B ratios.
