Geo-Events and Past Global Change

This interdisciplinary research theme aims at unravelling events in Earth history that involved major changes of environments and climate on a global scale. Sedimentological, stratigraphic and geochemical methods are use to investigate extreme palaeoclimatic and palaeoceanographic events preserved in the geological sediment-archives, e.g. during Quaternary Ice Ages or Oceanic Anoxic Events. Causes and consequences of past global change and their significance for past and today's changing climate are reconstructed. Research is part of large international geoscience science programs such as the UNESCO International Geoscience Program (IGCP), the International Continental Scientific Drilling Program (ICDP) and the Integrated Ocean Drilling Program (IODP).
