Glacial geomorphology of the central sector of the Cordilleran Ice Sheet, Northern British Columbia, Canada

open access: yesJournal of maps, 2021
Northern British Columbia was repeatedly covered by the Cordilleran Ice Sheet (CIS) during the glacial periods. However, its mountainous terrain and remote location have thus far impeded our understanding of the central sector of the ice sheet.

Glacial erosion: status and outlook

open access: yesAnnals of Glaciology, 2019
Glacier-erosion rates range across orders of magnitude, and much of this variation cannot be attributed to basal sliding rates. Subglacial till acts as lubricating ‘fault gouge’ or ‘sawdust’, and must be removed for rapid subglacial bedrock erosion. Such

Submarginal drumlin formation and late Holocene history of Fláajökull, southeast Iceland

open access: yesAnnals of Glaciology, 2016
Fláajökull is a non-surging outlet glacier draining the south-eastern part of the Vatnajökull, southeast Iceland. Fláajökull was stationary or advanced slightly between 1966 and 1995 and formed a prominent end moraine.

Using bed-roughness signatures to characterise glacial landform assemblages beneath palaeo-ice sheets

open access: yesJournal of Glaciology, 2022
Palaeo-glacial landforms can give insights into bed roughness that currently cannot be captured underneath contemporary-ice streams. A few studies have measured bed roughness of palaeo-ice streams but the bed roughness of specific landform assemblages ...

Glacial geomorphology of the Neutral Hills Uplands, southeast Alberta, Canada: The process-form imprints of dynamic ice streams and surging ice lobes

open access: yes, 2020
The Neutral Hills Uplands of southern Alberta, Canada is an area of complex and varied glacial landforms dominated by glacitectonic compressional structures but also containing expansive areas of hummocky terrain and kame and kettle topography.

Unravelling fluvial versus glacial legacy controls on boulder‐bed river geomorphology for semi‐alluvial rivers in Fennoscandia

open access: yesEarth Surface Processes and Landforms, 2023
River management is founded on predictable self‐organisation between river form and catchment controls in alluvial rivers. However, a substantial proportion of rivers are not fully alluvial.

Glacial evolution of the upper Gallego Valley (Panticosa mountains and Ribera de Biescas, Aragonese Pyrenees, Spain)

open access: yesPirineos: Revista de Ecología de Montaña, 1991
[es] Evolución glaciar del Alto Gallego (Montañas de Panticosa y Ribera de Biescas, Pirineo aragonés). Se reconstruye la evolución glaciar del Alto Gallego a partir del estudio de las formas de erosión y acumulación glaciar. Se describen diez pulsaciones,

The glacial geomorphology of the Mackenzie Mountains region, Canada

open access: yesJournal of Maps, 2023
During the Last Glacial Maximum, the Mackenzie Mountains region was glaciated by three distinct ice sources; the Laurentide Ice Sheet, the Cordilleran Ice Sheet, and independent montane glaciers. Rapid ice sheet thinning of the Laurentide-Cordilleran ice
