C11A:
Advances in Our Understanding of Processes at the Beds of Glaciers and Ice Sheets I Posters
Session ID#: 8185
Session Description:
The dynamic behavior of land-based and marine terminating glaciers often rests on processes at the ice-bed interface that are difficult to observe directly. However, these processes are crucial to understanding ice movement and the development of landscapes for both past and future climate.
This session includes contributions that aim to understand glaciological, geomorphic, geochemical, and geobiological phenomena at glacier beds. Processes of interest include ice and bed deformation, basal slip, subglacial hydrology, subglacial erosion and sediment transport, development of subglacial landforms and stratigraphy, and microbial alteration of basal environment, among others. We invite a range of approaches that capture all spatiotemporal scales of these processes, including field and geophysical observations, laboratory experiments, sedimentological and morphometric studies, and modeling efforts. We especially welcome novel, multifaceted studies that more comprehensively characterize this complex interface.
