Glacier and ice cap contribution to future sea level rise (postdoc @ TUDelft) (with S. Lhermitte & B. Wouters)
As a Marie Skłodowska-Curie postdoctoral fellow, I will aim at improving projections of the future sea level contribution from glaciers and ice caps (GICs). The goal is to make use of a variety of state-of-the art remote sensing products to constrain and validate a numerical ice flow model. The adopted strategy will consist of only modelling a subsample of all >200 000 GICs, but which represent a large fraction of the total GIC volume. This will allow us to use more complex methods than those used so far for global glacier and ice cap modelling (typically dimensionless or 1-D approaches).
Alpine glacier modelling (postdoc @ ETH Zürich & WSL Birmensdorf) (with M. Huss & D. Farinotti)
The aim of my first postdoctoral project (2017-2019) was to extend the GLObal Glacier Evolution Model (GloGEM) of Huss & Hock (2015, Frontiers in Earth Science) by incorporating a dynamic ice flow component. The newly developed model, GloGEMflow, was applied to the European Alps in order to project the future evolution of all glaciers under the EURO-CORDEX RCM ensemble. These results were also submitted to the second phase of GlacierMIP and are the starting point for creating a response time inventory of all glaciers in the European Alps (to be presented during the 27th IUGG General Assembly in Montreal).
From December 2012 to February 2013, I had the unique chance to join a Belgian-Japanese meteorite search expedition on the Nansen ice field on the Antarctic plateau (ca. 2900 m elevation), 120 km south of the Belgian Antarctic Station (Princes Elisabeth). During this expedition hundreds of blue ice samples surface samples were collected and these revealed clear climatic signals at the surface. To constrain the age of the ice, the terrestrial age of selected meteorites (i.e. the time since they entered the atmosphere) was determined. By combining this with satellite derived surface velocities and other sources of information, we tried to better constrain the mechanism behind the Nansen blue ice trap.
PhD (Vrije Universiteit Brussel) (supervised by P. Huybrechts)
My PhD (2013-2017) entitled ‘modelling the evolution of glaciers and ice caps in a changing climate’, consisted of modelling the dynamics of a Swiss mountain glacier (Vadret da Morteratsch) and a Greenlandic ice cap (Hans Tausen Iskappe). For this, I used 3-D higher-order ice flow models, which were coupled to surface mass balance models. Additionally, I also developed a visualization toolbox (TopoZeko), and performed a statistical regression analyses on the surface mass balance of the Morteratsch glacier complex.
