The Quaternary is defined by the cyclical growth and decay of continental ice sheets. These ice sheets had a huge impact on the Earth system, causing large fluctuations in sea level, altering air and ocean circulation patterns, and shaping the landscape. Insights from past ice sheets can improve our understanding of ice dynamics and past climate, which in turn, can help us to better forecast the future response of ice sheets to projected climate change. The aim of this session is to bring together researchers focused on reconstructing past ice sheets across all intervals of the Quaternary and understanding ice sheet processes at all spatial scales and from both the northern and southern hemispheres. We welcome studies on a variety of topics, including (i) glacial landforms and sediments, (ii) ice sheet reconstructions, (iii) ice sheet chronologies, (iv) marine and terrestrial archives, (v) glacio-isostatic adjustment and (vi) numerical ice sheet modelling.
