Interactive Effects of Iron and Temperature on the Growth of Fragilariopsis cylindrus ...
Iron and temperature are important drivers controlling phytoplankton growth in the Southern Ocean. Most studies examining phytoplankton responses to these variables consider them independently, testing responses to changing temperature under constant iron and vice versa. Consequently, we lack a phen...

Iron and temperature are important drivers controlling phytoplankton growth in the Southern Ocean.
