Lay Summary (English)

Lead
Lay summary
Our climate model of reduced complexity (Bern3D) will be developed to contain a very basic representation of the atmosphere in the form of an energy balance. Further development concerns the ocean components of the model which will be supplemented by a surface marine ecosystem model and a sediment model. This model will be used to calculate changes in reservoir ages of radiocarbon during abrupt climate change and many other biogeochemical applications. We will complete our greenhouse gas measurements (CO2, CH4, N2O) on ice samples from the European Project of Ice Coring in Antarctica (EPICA) back to 800,000 years including ice samples from the bottom 70 meters. Some time periods will be measured in high resolution. It is planned to complete the gas extraction device for isotopic composition of CO2 in polar ice. In groundwater hydrology we will address the question of stability of anthropogenic tracers with the combined use of 85Kr and 3H/3He ages. Tracer analyses and age determinations will be performed in various aquifers. Our palette of radionuclides offers various ways to constrain the age of a water sample.
