Phytoplankton Do Not Produce Carbon-Rich Organic Matter in High CO2 Oceans
The ocean is a substantial sink for atmospheric carbon dioxide (CO2) released as a result of human activities. Over the coming decades the dissolved inorganic C concentration in the surface ocean is predicted to increase, which is expected to have a direct influence on the efficiency of C utilizatio...
