Microscopic ocean algae called coccolithophores are providing clues about the impact of climate change both now and many millions of years ago. The study found that their response to environmental change varies between species, in terms of how quickly they grow.

Coccolithophores, a type of plankton, are not only widespread in the modern ocean but…

Rapid turnover and remodelling of lipid membranes could help phytoplankton cope with nutrient scarcity in the open ocean.

A team led by Patrick Martin of the University of Southampton's School of Ocean and Earth Science based at the National Oceanography Centre has shown that a species of planktonic marine alga can rapidly change the chemical…

A study led by Dr Stuart Painter of the National Oceanography Centre helps explain the formation of huge phytoplankton blooms off the southeast coast of South America during the austral summer (December–January). The region supports the highly productive Patagonian Shelf marine ecosystem, which includes a globally important fishery.

Coccolithophores…

Computer simulations performed by researchers at the National Oceanography Centre and the University of Glasgow show how oceanic stirring and mixing influence the formation and dynamics of plankton patches in the upper ocean.

Tiny free-floating marine plants called phytoplankton live in vast numbers in the sunlit upper ocean. Through the process…
