Mass exchange and motion of glacier tongues and subglacial sediments, under present conditions and conditions of ongoing rapid deglaciation

在联合提案中，通过将几个科学学科结合在一起来研究冰川前沿的地形变化。冰川学和地貌学项目研究冰川对冰川流中悬浮物和推移质输运的贡献。重点是融水生产，冰川运动，从集水区和冰下沉积物运输（沉积物级联模型）的沉积物供应的相互作用过程的关系。冰川学和地貌学分项目与其他分项目密切相关，正在进行系统内反馈的基础研究。分离的表面和冰下融化的测量表面消融和总体积变化来自激光扫描是新的。在厚度约为100米的冰舌上进行的高时空分辨率测量以及在温带冰舌上使用振动地震来调查冰的厚度和松动区的特性都是新的。

With the joint proposal the relief changes in the glacier forefield are investigated by bringing several scientific disciplines together. Theproject glaciology and geomorphology deals with the contribution of glaciers to the suspended load and bed load transport within theglacial stream. The focus is on the relationships of the interacting processes of meltwater production, glacier motion, supply of sediment from the catchment and the subglacial sediment transport (sediment cascade model). The subproject glaciology and geomorphology is closely connected to the other subprojects and is conducting fundamental research of intrasystematic feedbacks. The separation of surface and subglacial melting by measurements of the surface ablation and total volume changes derived from laser scans is new. The high temporal and spatial resolution of the measurements at the glacier tongue with a thickness of about 100 meters is new as well as the use of the vibroseismic at the temperate glacier tongue to investigate ice thickness and the properties of the zone of loosening.
