Glacial geomorphology of the northwest Laurentide Ice Sheet on the northern Interior Plains and western Canadian Shield, Canada

open access: yesJournal of Maps, 2023
The majority of the Northwest Territories of mainland Canada was covered by the Laurentide Ice Sheet during the Last Glacial Maximum. The increasing coverage of high resolution remotely sensed data provides new opportunities to map the glacial ...

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

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 Šumava / Bayerischer Wald mountains, Central Europe

open access: yesJournal of Maps, 2019
During Quaternary glacial periods, the Šumava / Bayerischer Wald mountains were subject to mountain glaciations. Recent studies have focussed mainly on the several well-developed cirques.

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.

Weichselian stratigraphy, geomorphology and glacial dynamics in southern Finnish Lapland [PDF]

open access: yesBulletin of the Geological Society of Finland, 2005
Quaternary stratigraphy and geomorphology were investigated by using aerial photo interpretation, digital elevation models and stratigraphical studies in southern Finnish Lapland.

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

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,

Glacial geomorphology of the Brabazon & Butler Downs, Rangitata Valley, South Island, New Zealand

open access: yesJournal of Maps, 2017
The inland valleys of New Zealand’s South Island were heavily glaciated during the last glacial cycle. Subsequent fluvial incision has eroded out glacial deposits from the valleys in many locations, making it difficult to reconstruct glacial dynamics and

Submarine geomorphology of the northeastern Baffin Island fiords and cross-shelf troughs

open access: yesJournal of Maps, 2019
This paper presents a series of 50 geomorphological maps of the seabed of northeastern Baffin Island fiords and cross-shelf troughs, in eastern Arctic Canada. The mapping was produced using swath bathymetry imagery from multiple bathymetry datasets.
