Glacially Driven Landscape Evolution: From Subglacial Processes to Downstream Systems
Glacially Driven Landscape Evolution: From Subglacial Processes to Downstream Systems
Session ID#: 282282
Session Description:
Glaciers reshape landscapes through subglacial and ice-marginal erosion, transport, and deposition, and through the release of large volumes of water, leaving imprints that extend far beyond formerly ice-covered regions. As glaciers retreat globally, understanding how ice-driven processes influence landscape evolution, from bedrock erosion to downstream sediment routing, is increasingly urgent.
This session focuses on geomorphic and sedimentary processes driven directly by glacier dynamics. We highlight how glacial signatures are preserved in landscapes and modified across spatial and temporal scales, and how these records inform broader questions of landscape evolution.
We invite contributions using field, remote sensing, laboratory, modeling, and emerging approaches to investigate processes beneath, adjacent to, and downstream of glaciers in past and present systems, and their links to climate and environmental change. We especially encourage interdisciplinary studies that connect processes across scales or regions and offer new insights into the evolving role of ice in shaping landscapes.
