Description :
A time-dependent model is used to investigate the interaction between climate, extent and fluctuations of Patagonian ice sheet between 45° and 48°S during the last glacial maximum (LGM) and its subsequent deglaciation. The sensitivity, coupled with the excellent geomorphic record of past fluctuations of the NPI's eastern outlet lobes, means that the area is ideally located to address some of the significant outstanding issues centred on the past latitudinal migration of the moisture-bearing westerlies and the forcing mechanisms behind regional climate and inter-hemispheric climatic synchronicity.
