Research profile:

Monsoonal Systems are the dominating features controlling the climate in the tropical and subtropical regions of the world. The most striking characteristics of monsoons are seasonally contrasting climatic conditions (wet- and dry-seasons) in combination with a complete reversal of wind-directions. Consequently, monsoonal systems have a large impact on the hydrological cycle in the affected regions. Within my research, I focus on the South American Monsoon, which is mainly controlled by seasonal shifts in the Intertropical Convergence Zone and the South Atlantic Convergence Zone (ITCZ & SACZ) across the continent.

Particularly, my research focusses on the reconstruction of dynamics and variations in the South American Monsoon and accompanying hydrographical changes in the tropical- and subtropical South Atlantic since the late Pleistocene. Additionally, the interplay of low-latitudinal climatic systems (i.e. ITCZ and SACZ) to high latitude climate forcing (e.g. the glacial-interglacial cycle) is another key aspect.

For that purpose, a multiproxy approach on marine sediment archives is used to reconstruct paleoclimatic and hydrographic feedbacks in response to changes in the monsoonal system. These geochemical proxies include:

  • Sea Surface Temperature (SST) reconstructions from planktic foraminiferal Mg/Ca
  • Reconstruction of continental river run-off by foraminiferal Ba/Ca
  • Assessment of paleo salinities by combining δ18O and Mg/Ca derived temperatures from planktonic foraminiferal tests.
  • δ13C to assess paleo-productivity
