Research Focus and Objectives

Palaeoclimatological Research Focus

Her general scientific interests are in unraveling the late quarter climate history from high definition marine climate archives. At the foreground is a better understanding of fast changing climates on multidecadial timescales which are comparable to anthropogenical climate change through quantitative reconstructions of quarterly climate scenarios that can be used as analogs for future climate changes.

Objectives of particular interest are:

  • The quantifiable reconstruction of marine climatic variables (palaeotemperatures, -salinities, -densities, sea ice cover, -productivity, CO2- pressure in surface water) through geochemical signatures in shells of foraminiferas and micropalaeontological approaches
  • The development of quantifiable “proxies” with stable isotopes, trace metals micropalaeontological approaches. And particularly a better understanding for geochemical signal formation in chalk-shelled microorganisms as basis for a new generation of more precise palaeoenvironmental proxies with an eye on developing new high definition climate archives.
  • The reconstruction of the stability of Atlantic meridional "overturning" circulation (AMOC) during the Holocene and early interglacial period as potential analogs for future global warming scenarios.
  • Global and regional reconstructions of high glacial sea surface data and providing reconstructions for the validation and initialization of climate models.
  • Understanding the palaeoecology and evolution of planktonic foraminifera as the most important carrier of geochemical signals in marine sediments.
  • Better understanding of marine ?18O, ?13C cycles: The role of marine plankton in the global CO2 cycle.
  • Understanding the role of ocean passages for ocean circulation, climate and evolution. Start and progression of the Northern Atlantic thermohaline circulation in the Oligocene/Miocene and the progression during the glaciation of the northern hemisphere.
