Short-term acidification promotes diverse iron acquisition and conservation mechanisms in upwelling-associated phytoplankton
Abstract Coastal upwelling regions are among the most productive marine ecosystems but may be threatened by amplified ocean acidification. Increased acidification is hypothesized to reduce iron bioavailability for phytoplankton thereby expanding iron limitation and impacting primary production. Here...

Abstract Coastal upwelling regions are among the most productive marine ecosystems but may be threatened by amplified ocean acidification.

A combined physiological and multi-omics approach was applied to trace metal clean incubations that introduced 1200 ppm CO2 for up to four days.
