This study highlights the importance of manganese (Mn) next to iron (Fe) for the growth of specific Southern Ocean phytoplankton groups with important implications for carbon export in the Weddell Sea. A Fe-Mn bottle amendment experiment and an aggregation experiment were performed with a natural ph...
