The subglacial hydrological system of Greenland and Antarctica - known unknowns and current modelling approaches

The base of the ice sheets in Greenland and Antarctica is over vast areas wet, which makes ice sheet dynamics a gravity driven lubricated flow problem. The subglacial system is unfortunately nearly inaccessible and only indirect observations can be conducted. These show that lakes exist underneath the Antarctic ice sheet and that the summer melt in Greenland fills lakes at the surface, which drain within hours and deliver massive amounts of water into the subglacial hydrological system. Our attempts to model this system are based on an equivalent layer approach. We will present recent simulations of Greenland and Antarctica and ideas of how to constrain model parameters in the future. 

About Prof. Dr Angelika Humbert

Angelika Humbert is a glaciologist at the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research, and a Professor of Ice Modelling at the University of Bremen’s Faculty of Geosciences. Born in Darmstadt in 1969, she studied Physics at the TU Darmstadt from 1989 to 1996, following parental leave between 1996-2000. She completed her doctorate in 2005 at the TU Darmstadt on ice shelf mechanics. After completing research projects at the TU Darmstadt and the WWU Münster, she took up a professorship at Universität Hamburg’s Cluster of Excellence CliSAP, where she established the Glaciology Research Group. She has been at the Alfred Wegener Institute, where she currently leads a group focusing on ice sheet modelling and remote sensing, since 2012.

The modelling focuses on simulating ice-sheet dynamics in Greenland and the Antarctic, in order to predict future sea level rise due to melting ice sheets. In this regard, she also investigates processes like iceberg calving, slides, and how lakes form on and beneath the ice sheets. She also participates in expeditions to the Arctic and Antarctic. For her research she uses the AWI’s two polar research planes, the data from which offers insights into the internal structure of the glaciers.

Further, Angelika Humbert is developing and employing satellite-based methods for observing glaciers and ice sheets in the polar regions in detail. She is convinced that we will only be able to correctly assess the current and future condition of the ice sheets, and evaluate the risks they pose, when we succeed in combining high-resolution satellite data and ice models. Her passion for glaciers ice goes is so great that Angelika Humbert describes her fascination with it as her personal motivation. For her, ice is a unique material, not just because of its many mechanical properties, which have to be included in models, but above all because its direct ties to the ocean and the atmosphere result in a multitude of interactions.
