Paleo Glacier Dynamics

P6的总体目标是通过研究过去的冰川、冰川变化和冰缘过程，为重建人类占领初期的贝尔山脉晚更新世气候和景观演变作出贡献。在第一阶段，P6的研究重点放在以前冰川的时间和空间范围上，作为确定上游山谷和Sanetti高原上(P1和P2感兴趣的)宜居区的先决条件。根据已确定的冰川年代学，(与P1和P2合作)证明，史前人类的存在与大范围冰川时期相吻合。然而，绘制了地图和确定日期的冰川阶段之间的气候和冰川变化仍然知之甚少。因此，在第二阶段，P6的目标是通过冰川物质平衡和冰流模拟扩大地貌测绘和地表暴露年代测定，以重建连续的冰川变化性，量化山谷中可利用的冰川融水数量(与P1有关)，并(与P3、P5、P7和C2合作)确定上一个冰川周期的温度和降水变化。

The overall aim of P6 is to contribute to the reconstruction of the Late Pleistocene climate and landscape evolution of the Bale Mountains during the early phase of human occupation by studying past glaciations, glacier variations and periglacial processes. In Phase 1, research of P6 focused on the timing and spatial extent of former glaciations as a prerequisite to identify habitable areas (of interest for P1 and P2) in the upper valleys and on the Sanetti Plateau. Based on the established glacial chronology, it was demonstrated (in collaboration with P1 and P2) that the prehistoric presence of humans coincided with a period of extensive glaciation. However, the climate and glacier variations between the mapped and dated moraine stages remain poorly understood. In Phase 2, P6 therefore aims to expand geomorphological mapping and surface exposure dating by glacier mass balance and ice-flow modelling in order to reconstruct the continuous glacier variability, quantify the available amount of glacial meltwater in the valleys (relevant for P1) and determine (in cooperation with P3, P5, P7 and C2) temperature and precipitation changes over the last glacial cycle.
