Abstract

Read online

Findings regarding the impacts of ocean acidification (OA) on the growth and N2 fixation of Trichodesmium are conflicted. Here, the authors find that Trichodesmium growth rates decrease under OA primarily due to reduced nitrogenase efficiency and OA under RCP 8.5 could reduce the N2 fixation potential of Trichodesmium by 27%.
