Title | Linking South American dust transport and Southern Ocean iron/manganese fertilization |
Description | The Southern Ocean is characterized by a large pool of unused nutrients, primarily because the availability of micronutrients such as iron (Fe) and manganese (Mn) is limited inthe surface waters. Past climate intervals experienced increased input of mineral dust to the Southern Ocean. The partial dissolution of this input reduced the Fe/Mn limitation and promoted primary productivity resulting in a net drawdown of atmospheric CO2 during the ice age intervals. It is known that South America is a major source of mineral dust for the Southern Ocean, but tracing the signal from existing marine records across the land-ocean interface back to the dust source regions is still incomplete thus limiting our understanding of the paleoclimatic mechanisms involved in the Southern Ocean dust-Fe/Mn feedback. |
