Abstract The Southern Ocean is an important regulator of global CO2 levels and likely had a
key role in lowering atmospheric CO2 levels during the Last Glacial Maximum (LGM) and …

Proxy records from across the Southern Hemisphere show significant local to regional scale
variability in climatic and environmental conditions during late Marine Isotope Stage 3 and …

Natural iron fertilization of the Southern Ocean by windblown dust has been suggested to
enhance biological productivity and modulate the climate,–. Yet, this process has never …

While several processes have been identified to explain the decrease in atmospheric CO 2
during glaciations, a better quantification of the contribution of each of these processes is …

Antarctic ice core records suggest that atmospheric CO2 increased by 15–20 ppm during
Heinrich stadials (HS). These periods of abrupt CO2 increase are associated with a …

The role of atmospheric iron deposition in influencing primary productivity in the iron-limited
Southern Ocean has been a subject of longstanding interest. This thesis provides a …
