My research interests span different temporal and spatial scales. From mass loss of the Greenland ice sheet, to the search of the “oldest ice” in Antarctica, to the ancient water ice deposits on Mars.

Firn properties with wireless sensors

The processes taking place in the snow and firn are extremely important for investigating the mass loss from the polar ice sheets, for understanding satellite measurements and for ice-core studies. This project is a collaboration with Liz Bagshaw from University of Cardiff. Together we are using wireless sensors (developed by Liz and colleagues) that measure and transmit information about pressure, temperature and electrical conductivity. More information about the suite of sensors can be found on the CryoEgg website. We presented our preliminary findings at the European Geosciences’ Union’s General Assembly in 2017 (abstract) and currently have a paper in review.

The search for the Oldest Ice

One of the key goals for past climate studies is to retrieve an ice core containing ice older than 1.5 million years. By obtaining an undisturbed ice core stretching that far back in time, we will get closer to understanding a main switch in climate: The time where ice-age cycles changed from lasting 40,000 years to 100,000 years. During my time at the Alfred Wegener Institute I worked on the “Beyond EPICA – Oldest Ice” project, a large European project aiming to identify potential drill-sites. My work was focussed on the Dome Fuji region in East Antarctica and has been featured in different news media – including the Danish “Ingeniøren“.
