Spatially variable basal conditions are thought to govern how ice sheets behave at glacial time scales (>1000 years) and responsible for changes in dynamics between the core and peripheral regions of the Laurentide and Fennoscandian ice sheets. Basal... Read More about The impact of spatially varying ice sheet basal conditions on sliding at glacial time scales.

Anthropogenic contaminants in glacial environments II: Release and downstream consequences (2022)
