Why Glaciology?

    As recently summarized by S. Marshall (EPSL, 2005), glaciers and ice sheets play a dynamic role in Earth’s climate system, influencing regional- and global-scale climate and responding to climate change on time scales from years to millennia. They are also an integral part of Earth’s landscape in alpine and polar regions, where they are an active agent in isostatic, tectonic, and Earth surface processes. [...] Quantitative understanding of glacier dynamics is important to Earth systems models which examine climate evolution over long time scales, as well as shorter-term forecasts of glacier and ice sheet response to climate change in the decades and centuries ahead. In other words, the information that glaciers and ice sheets reposit can not only be regarded as valuable archives of past environmental conditions, but also as indicators of current environmental change. This is why people from various Science disciplines have gathered since a few decades to study the Cryosphere, that is, places on Earth where ice is present.

    In this context, the ULB Glaciology Lab mostly focuses on the physical and chemical characteristics of the basal zone of terrestrial ice bodies. This basal zone comprises what is known as "basal ice", i.e. ice present at the interface between the ice trunk and its substrate. Studying basal ice is crucial in glaciology, because basal characteristics are a major control on the flow behaviour of the entire ice mass. Geochemical and structural analysis of the basal zone of glaciers and ice sheets around the world has actually brought first-order information on how ice reacts to environmental changes materialized by e.g. fluctuations in precipitation rate, in meltwater discharge or in impurity content. In fact, basal ice studies provide, if one can retrieve it, a "frozen picture" of the physical state of the ice body.

    The research program we have recently launched at ULB, ASPI, seeks to investigate subglacial processes and interactions with the ice sheet, through a multidisciplinary approach. This comprises numerical ice-sheet modelling, ice-core analysis, laboratory experiments and field investigations. Such multidisciplinary approach will facilitate the glaciodynamic study of the subglacial interface in its broad sense, such as interactions with subglacial and proglacial lakes, basal hydrology, ice streams, grounding line dynamics, and the imprints (erosional) and remnants (glacial sedimentation) of past basal ice presences on the continental shelves.
