Sanne Veldhuijsen is a PhD Candidate at the Institute for Marine and Atmospheric Research (IMAU) at Utrecht University in the Netherlands. Her research focuses on modelling the current and future Antarctic firn layer, for which she uses the IMAU Firn Densification model (IMAU-FDM) in combination with in-situ measurements and remote sensing data.

In this poster, we study the future evolution of (accessible) firn air content over the Antarctic ice sheet under three different warming scenarios using an updated model. Our results underline the different response of low- and high accumulation ice shelves to atmospheric warming, showing increased near-surface ice slab formation on low accumulation ice shelves, thereby accelerating the depletion of the firn’s meltwater buffering capacity.
