Ice sheet humming and climate change
The Antarctic and Greenland ice sheets will play a major role for global sea level rise in the decades and centuries to come. Antarctic climate and mass balance have been highlighted by the Intergovernmental Panel on Climate Change (IPCC) as key sources of uncertainty when predicting the future clim...

The Antarctic and Greenland ice sheets will play a major role for global sea level rise in the decades and centuries to come. Antarctic climate and mass balance have been highlighted by the Intergovernmental Panel on Climate Change (IPCC) as key sources of uncertainty when predicting the future climate system and sea level, and that significant challenges remain in understanding and representing the dynamics of the Antarctic ice sheets. At the same time, the ice sheets are a unique archive of the paleo atmosphere. The European project “Beyond EPICA” started to retrieve an ice core going back 1.5 Ma, into the Mid-Pleistocene Transition (MPT). Both aspects, correctly estimating future sea-level contributions and deciphering the paleo-climate archive, rely on decrypting the physical processes that control ice-sheet evolution over time. In this seminar, I will present the USIAS project “Characterising ice-sheet properties and processes with novel seismic monitoring technology”, with which we establish new methodologies to be employed during the “Beyond EPICA” drilling to improve our knowledge of ice-sheet properties and dynamics.
