Topics
FG Daphne
One major focus of our working group is to better understand the basic mechanisms which control speleothem growth and composition using a combined application of field and laboratory experiments. In particular, the impact of kinetic fractionation processes on the carbon and oxygen isotope signals recorded. The knowledge of these basic mechanisms should deliver high-resolution information about the intensity of past precipitation and temperature on the continents (www.FG-Daphne.de).
Dating and interpretation of marine and continental archives (sediments, speleothems, corals...)
Another aim is to determine the intensity of the magnetic field during the past 350,000 years via the measurement of the concentration of 10Be in marine sediments, and to test its relationship to climate changes in the past.
