Deciphering the response of Southern Ocean phytoplankton to climate change: Current research projects and future research directions
The Southern Ocean is responsible for 40% of the oceanic uptake and storage of anthropogenic CO2 and the drawdown of CO2 via photosynthesis by Southern Ocean phytoplankton accounts for 10% of this uptake. Phytoplankton forms the basis of the Southern Ocean food web supporting large animal population...
