Glacial geomorphology of Newfoundland, Canada

Journal of Maps
We present a synthesis of glacial geomorphology comprising Newfoundland and the surrounding continental shelf. During the last glaciation, this region was encompassed by the Newfoundland Ice Cap that coalesced with the Laurentide Ice Sheet and extended ...

Paleoglacial footprint and fluvial terraces of the Shaluli Shan, SE Tibetan Plateau

Journal of Maps, 2021
This study provides mapping of glacial and fluvial geomorphology in the Shaluli Shan region on the eastern margin of the south-eastern Tibetan Plateau. Based on TanDEM-X 12 m elevation data and GoogleEarth imagery, glacial valleys, ice-marginal moraines,

Glacial geomorphology in the Wicklow Mountains, Ireland

Journal of Maps, 2023
We present a detailed 1:50,000-scale glacial geomorphological map covering ∼450 km2 of the Wicklow Mountains, eastern Ireland. The region was glaciated at the Last Glacial Maximum, but little is known about the timing and pattern of deglaciation during ...

Effects of Glacier and Geomorphology on the Mechanism Difference of Glacier-Related Debris Flow on the South and North Banks of Parlung Zangbo River, Southeastern Tibetan Plateau

Advances in Civil Engineering, 2022
Alpine glaciers are vulnerable to climate changes, and their recession due to warming has already induced a large number of geohazards closely related to the glacial motion, such as debris flow. Strong coupling of the geology, geomorphology, climate, and

Sedimentation and geomorphology of the Ruoergai Basin outlet reach at the source of the Yellow River: Response to the late quaternary glacial debris flow damming events

Frontiers in Earth Science, 2023
Fluvial terraces in the source of the Yellow River suggest that Ruoergai Basin was connected with the lower reach after ∼10 ka, much younger than the uplift chronology of the Tibetan Plateau.

Glacial geomorphology between the Gran Campo Nevado and Estrecho de Magallanes, Chile (52–53°S, 73°W)

Journal of Maps, 2023
We present the first extensive high-resolution glacial geomorphic map west of the Andean Cordillera in southernmost Chile (52.8–53.1°S, 73.0–73.9°W). The map extends over 1565 km2 and is based on high-resolution satellite images and aerial photographs ...

The glacial geomorphology of sub-Antarctic Marion Island

Journal of Maps, 2021
Since the discovery of glacial features on sub-Antarctic Marion Island, the character and extent of a historic glacial period have remained an important research focus for earth science investigations.

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

Journal 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

Annals 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

Journal 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 ...
