A Generalized Interpolation Material Point Method for Shallow Ice Shelves. 2: Anisotropic Nonlocal Damage Mechanics and Rift Propagation

open access: yesJournal of Advances in Modeling Earth Systems, 2021
Ice shelf fracture is responsible for roughly half of Antarctic ice mass loss in the form of calving and can weaken buttressing of upstream ice flow.

The lowermost last‐glacial equilibrium line altitude in the Taiwanese Central Mountain Range and its implications for the palaeoclimate and the tropospheric moisture transport in East Asia

open access: yesJournal of Quaternary Science, EarlyView.
Abstract The high mountains of Taiwan provide a unique location for Quaternary palaeoclimate research in East Asia and the north‐western Pacific. This study applies geomorphological field mapping and rock surface exposure dating with paired (10Be/26Al) in situ‐produced terrestrial cosmogenic nuclides to identify and date glacial landforms and boulders ...

Remote Detection of Surge-Related Glacier Terminus Change across High Mountain Asia

open access: yesRemote Sensing, 2021
High Mountain Asia (HMA) hosts the largest glacier concentration outside of polar regions. It is also distinct glaciologically as it forms one of two major surge clusters globally, and many glaciers there contradict the globally observed glacier ...

Contributions to the Glaciology of the Antarctic [PDF]

open access: yesJournal of Glaciology, 1956
AbstractDuring a winter in Terre Adélie in 1951 (Antarctica) certain glaciological studies were made. These were strongly hampered by the extraordinary strength and persistence of the blizzards from the ice cap. Near the coast the wind dominates the distribution of snow completely. The firn limit on the open ice cap is at a height of 450 m. (1500 ft.).

Long‐term hydrologic connectivity on the Australian dryland margins: Evidence from the Willandra Lakes World Heritage Area over the last 60 ky

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT The semi‐arid Australian continental inland is increasingly subject to climatic extremes such as drought and flooding. Combined with the exceptionally low topographic relief characteristic of this region, hydroclimatic extremes can have an enormous impact on the land surface.

Toward Improved Understanding of Changes in Greenland Outlet Glacier Shear Margin Dynamics in a Warming Climate

open access: yesFrontiers in Earth Science, 2018
The Greenland Ice Sheet has experienced accelerated mass loss over the last couple decades, in part due to destabilization of marine-terminating outlet glaciers.

At the far end of everything: A likely Ahrensburgian presence in the far north of the Isle of Skye, Scotland

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT A Late Upper Paleolithic (LUP) site containing Ahrensburgian‐type stone tools has been discovered at South Cuidrach, Isle of Skye, Scotland. Together with a group of intertidal stone circular alignments also recently discovered on the island, this new evidence for the occupation of northern Scotland also represents the most northerly LUP site ...

Estimation of Supraglacial Dust and Debris Geochemical Composition via Satellite Reflectance and Emissivity

open access: yesRemote Sensing, 2012
We demonstrate spectral estimation of supraglacial dust, debris, ash and tephra geochemical composition from glaciers and ice fields in Iceland, Nepal, New Zealand and Switzerland.

Dating the Middle Palaeolithic of Fumane Cave by the combined ESR/U‐series method

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Fumane Cave, located in Northern Italy, is a major prehistoric site for understanding late Neandertal and early modern human behaviours. The cave contains a 12‐m‐thick stratigraphic sequence of Middle and Upper Palaeolithic layers, which have yielded a number of flint artefacts and faunal remains.

Modelling erratic dispersal accounting for shifting ice flow geometries: A new method and explanations of erratic dispersal of the British–Irish Ice Sheet

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Glacial erratics are geologically distinctive rocks transported away from their source area by ice sheets and deposited in lithologically different bedrock areas. They have attracted much scientific curiosity with >24 000 observations across the British Isles.
