An article published in the journal “Limnology and Oceanography” describes a study on the circulation of carbon in the oceans. A team of researchers from Florida State University (FSU) studied the area between 100 and 1,000 meters of depth discovering that very simple organisms belonging to the group called Phaeodarea consume carbon-rich particles that are sinking before they reach the seabed, where they could otherwise be sequestered for millennia. They’re tiny organisms but they could have an impact on the carbon cycle and therefore on climate.
