An interdisciplinary team of scientists has discovered that, contrary to general scientific belief, iron in nondissolved particle form can stimulate phytoplankton growth, and that the chemical form that particulate iron takes is critical to ocean photosynthesis.

Tiny microbes called phytoplankton are churning away in the oceans, taking in carbon dioxide and producing the oxygen we breathe. Scientists recognize their value, but many questions remain about what will happen to their productivity as the oceans warm, carbon dioxide levels rise, and the nutrients they rely on become scarce. A new study explores those questions using a mix of techniques from genomics and oceanography and a newly created database of millions of phytoplankton RNA strands contributed by scientists from labs around the world.
