This proposal focuses on the interactions between paleo-glacier dynamics and mountain erosion in the western European Alps, during the paleoclimatic conditions of the last glacial cycle (100 kyr). The central objective is to develop a deeper understanding of both past climatic conditions and erosion patterns within the Alps and their foreland, using information presently available in the literature to identify the remaining gaps in the records and thus provide a more complete framework from a multi-disciplinary approach. The proposed research follows two complementary directions: (1) reconstructions of high-resolution glacier fluctuations and paleoclimatic conditions in the Alps using innovative methods in earth-surface geochronology; and (2) the quantification of glacial erosion patterns and subglacial sediment transport times from detailed investigation of the geological record in the Alpine foreland. Paleoclimatic and erosion data will then be used as quantitative constraints to calibrate numerical ice models, with the aim to investigate the long-term glacial evolution of the Alps and their foreland. This will ultimately provide a better understanding of the physical processes involved in glacial erosion and sediment transport beneath glaciers.
