Southern Ocean phytoplankton physiology in a changing climate
© 2016 Elsevier GmbH The Southern Ocean (SO) is a major sink for anthropogenic atmospheric carbon dioxide (CO2), potentially harbouring even greater potential for additional sequestration of CO2 through enhanced phytoplankton productivity. In the SO, primary productivity is primarily driven by botto...
