Short summary
Diatoms commonly dominate algal blooms. However, little is known regarding how diatoms overcome CO2 limitation and maintain growth during blooms. Our results show that enrichment of phosphorus enhances diatoms’ photosynthetic pigment, photosynthetic rate, and the capacity for inorganic carbon acquisition. This study indicates the essential role of phosphorus in coping with CO2 limitation for diatoms and sheds light on how bloom-forming algae cope with carbon limitation during blooms.
