Cryosphere is cool! Modelling the Greenland Ice Sheet using a 3D ice sheet model

Ilaria Tabone (Univ. Complutense de Madrid)

The Greenland and the Antarctic Ice Sheets, the largest ice sheets on Earth, are responsible each year for discharging hundreds of gigatons of ice into their surrounding oceans. Investigating their stability is of outstanding importance to predict future sea-level variations, especially in a world, which is currently experiencing a climate change. Remote sensed (e.g. from satellite radar or laser altimeters) and direct (in-situ) observations are fundamental to define the current state of an ice sheet. However, projections of how these polar ice sheets might respond to a changing climate can be made only by coupling these observations with a significant modelling work. Many mathematical models based on the physical laws governing ice motion can be used to describe the evolution of ice. Yet, depending on the size and the dynamics of the frozen region we want to study (e.g. fast-flowing glaciers, ocean-ending glaciers or the whole ice sheet itself), some models are more suitable than others. In this seminar we will focus on the category of ice sheet models that are able to simulate the evolution of large-scale ice sheets, even as big as Greenland or Antarctica. In particular, we will glance at the theory behind a brand new 3D continental ice sheet model and we will see how it can be used to investigate the future (and also past) evolution of the Greenland Ice Sheet as an example. We will see that studying polar ice sheets is also possible from the most remote places on earth!

Gesamtübersicht Kolloquiumsprogramm im Sommersemester 2019

******

Zukünftig werden pro Semester bis zu vier Kolloquiumsvorträge im Hörsaal C (Kochstr. 4, Innenstadt) angeboten.
Zusätzlich finden spezielle, mehr forschungsorientierte Kolloquiumsvorträge in den Seminarräumen im Institut für Geographie (Wetterkreuz 15, Erlangen-Tennenlohe) statt.

Die Teilnahme sowohl an Vorträgen in Tennenlohe als auch im Hörsaal C werden durch Abstempeln im Kolloquiumspass als Leistungsnachweis dokumentiert, dasselbe gilt  weiterhin auch für den Besuch des Geo-Cafés und der FGG-Vorträge.
