The Arctic Ocean now counts two "spring" blooms. This discovery was documented in a study lead by CEN’s researcher Marcel Babin and his colleagues. The study was selected as one of the top 10 scientific discoveries of 2014 by the magazine Québec Science. The study shows that a second phytoplankton bloom, phenomenon usually observed during the spring period, also occurs in autumn. A substantial reduction of the ice cover seems to explain the autumnal peak in phytoplankton productivity observed using satellite imagery. A bimodal biological productivity is usually observed in temperate areas and its apparition in the arctic could bring important changes to marine ecosystems.
