Haemolytic activity of live Phaeocystis pouchetii during mesocosm blooms

Mass sedimentation of Phaeocystis pouchetii in the Barents Sea

Mass sedimentation of gelatinous rolonies of the prymensiophyte Phaeocystis pouchetii were observed In the upper !00 m of Atlantic v> ater in the central Barents Sea. Sedimentation rates of paniculate organic carbon and nitrogen as weCl as pigments were the highest recorded so far from oceanic environments of the North Atlantic or coastal areas of Norway. High relative concentrations of phytopl...

Phaeocystis antarctica blooms strongly influence bacterial community structures in the Amundsen Sea polynya

Rising temperatures and changing winds drive the expansion of the highly productive polynyas (open water areas surrounded by sea ice) abutting the Antarctic continent. Phytoplankton blooms in polynyas are often dominated by the haptophyte Phaeocystis antarctica, and they generate the organic carbon that enters the resident microbial food web. Yet, little is known about how Phaeocystis blooms sh...

Phaeocystis blooms in the global ocean and their controlling mechanisms: a review

Phaeocystis is a genus of marine phytoplankton with a world-wide distribution. It has a polymorphic life cycle alternating free-living cells and colonies but develops massive blooms under the colony form in nutrient (major)-enriched areas (mostly nitrates) of the global ocean. Among the 6 species, only 3 (P. pouchetii, P. antarctica, P. globosa) have been reported as blooming species. However i...
