Time: 1pm Eastern Time / 11am Mountain Time
Liam Carson will be presenting Proglacial Retrogressive Thaw Slumping, Svalbard.
The Arctic is warming rapidly, driving cryospheric changes like glacial retreat and permafrost thaw that transform proglacial landscapes. This study examines ice-cored moraine dynamics in Scott Turnerbreen (STB) and Longyearbreen (LYB) in central Spitsbergen using UAV surveys, satellite imagery, and Ground Penetrating Radar. Since 2018, STB lost 67,350 m³ of material, while LYB lost 115,252 m³, driven by larger Retrogressive Thaw Slumps (RTS). The findings highlight the impacts of ice-cored moraine thaw on geomorphology, sediment release, and hydrology, emphasizing the need for continued monitoring and predictive modelling.
