Transference of Atmospheric Hydroxyl Radical to the Ocean Surface Induces High Phytoplankton Cell Death
Abstract Hydroxyl radical (OH), the main atmospheric oxidant at the global scale, is believed to play an important role in the dynamics of dissolved organic matter in the sea. Herein, we provide evidence, on the basis of seven experiments performed in contrasting ecosystems (subtropical NE Atlantic...
