The evolution of glaciers, ice caps, and ice sheets can have a profound impact on the Earth system. For example, during the Quaternary, ice sheet growth and decay resulted in the fluctuation of sea levels, alteration of global air and ocean circulation patterns, sculpting of the landscape, and reorganisation of continental drainage. Landforms and sediments provide important information about the dimensions, distribution, and dynamics of past ice sheets. This record can be used to understand ice dynamics, reconstruct climate, and refine our understanding of the future response of ice masses to variations in climate. The aim of this session is to bring together researchers focused on reconstructing past glaciations at all spatial scales and from all parts of the world. We welcome studies of all relevant aspects, for example (i) glacial landforms and sediments, (ii) glacial reconstructions and chronologies, (iii) glaciologic and climatic interpretations, and (iv) numerical modelling. While the focus of the session will be Quaternary glaciations, studies from any geological period are encouraged to fully address the diversity of the topic.
