Advances in understanding subglacial meltwater drainage from past ice sheets
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-04-17)Meltwater drainage beneath ice sheets is a fundamental consideration for understanding ice–bed conditions and bed-modulated ice flow, with potential impacts on terminus behavior and iceshelf mass balance. While contemporary observations reveal the presence of basal water movement in the subglacial environment and inferred styles of drainage, the geological record of former ice sheets, including ... -

Exceptions to bed-controlled ice sheet flow and retreat from glaciated continental margins worldwide
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-01-13)Projections of ice sheet behavior hinge on how ice flow velocity evolves and the extent to which marine-based grounding lines are stable. Ice flow and grounding line retreat are variably governed by the coupling between the ice and underlying terrain. We ask to what degree catchment-scale bed characteristics determine ice flow and retreat, drawing on paleo-ice sheet landform imprints from 99 sites ... -
Subglacial water storage and drainage beneath the Fennoscandian and Barents Sea ice sheets
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-10-17)Subglacial hydrology modulates how ice sheets flow, respond to climate, and deliver meltwater, sediment and nutrients to proglacial and marine environments. Here, we investigate the development of subglacial lakes and drainage networks beneath the Fennoscandian and Barents Sea ice sheets over the Late Weichselian. Utilizing an established coupled climate/ice flow model, we calculate high-resolution, ...
