The influence of the lithological and geotechnical properties of rocks on the morphology of glacial valleys

open access: yes, 2013
The glacial valley cross-profile has traditionally had its development attrituted to the physical properties of the eroding glacier, with the input of the properties of the eroded rock mass to the development of the valley system considered in a purely ...

Assessing the catastrophic break-up of Briksdalsbreen, Norway, associated with rapid climate change

open access: yes, 2011
Recent research has raised concerns about the potential influence of rapid climate change on the stability of major ice sheets. The behaviour of glaciers is determined largely by the processes and conditions operating at their base.

Deep Learning-Based Remote Sensing Monitoring of Rock Glaciers—Preliminary Application in the Hunza River Basin

open access: yesRemote Sensing
Rock glaciers have been recognized as key indicators of geomorphic and climatic processes in high mountain environments. In this study, Sentinel-2 MSI imagery and topographic data were integrated to construct enhanced feature sets for rock glacier ...

Geochronological reconstruction of the Lateglacial deglaciation in the Arve Valley (Northern French Alps)

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT The timing and spatial patterns of glaciers retreat in the Northern French Alps during the Lateglacial (19.0–11.7 ka) remain debated, reflecting discrepancies among available chronological data sets. The complex interactions between major glaciers, such as the Rhône and Arve glaciers to the north and the Isère glacier to the south, represent a

Reconstructing Loch Lomond Stadial Glaciers and Climate in the south-west English Lake District [PDF]

open access: yes, 2009
The most recent glaciation of the English Lake District occurred during the Loch Lomond Stadial (Younger Dryas) when full glacial conditions returned to the British Isles.

Isoetes ×atruensis (Isoetaceae – Lycopodiopsida), a new interspecific sterile hybrid from Rajasthan of Western India

open access: yesNordic Journal of Botany, EarlyView.
Isoetes ×atruensis hyb. nov. is shown to be a triploid (2n = 3× = 33 + 1) sterile interspecific hybrid between diploid (2n = 2× = 22 + 1) I. coromandelina and tetraploid (2n = 4× = 44 + 1) I. rajasthanensis. It has been found in two locations in Rajasthan, India.

Downwasting and supraglacial lake evolution on the debris-covered Ngozumpa Glacier, Khumbu Himal, Nepal

open access: yes, 2015
In recent decades, the downwasting of several debris-covered glaciers in the Himalaya has led to the formation of large and potentially hazardous moraine- dammed lakes.

The hunt for Scabiosa trenta Hacq: how the pursuit of a phantom ignited a passion for botany and mountaineering

open access: yesNordic Journal of Botany, EarlyView.
Scabiosa trenta Hacq. was first described in 1782 by Balthasar Hacquet, with its specific epithet referring to the Trenta Valley in Slovenia. Since then, S. trenta has been the focus of numerous mountaineering and botanical expeditions, particularly by the alpinist Julius Kugy during the Golden Age of Alpinism, a period in the second half of 19th ...

TIFF images of rock glacier surface velocities for Valley Calchaquíes region, Salta Province, Argentina

open access: yes
For the Valles Calchaquíes region, Northwestern Argentina, we derived rock glacier surface velocities (in unit m/a) from multi-temporal aerial and satellite imagery using a feature tracking approch.

Connecting the distribution and diversification of marine plants

open access: yesOikos, EarlyView.
Integration of the evolutionary history with distribution of extant species is necessary to explain present‐day diversity, particularly for ‘foundation' species, such as seagrasses, which create habitats of socioecological relevance. Here, we resolved if varying evolutionary history of seagrass families has imprinted the distribution ranges of extant ...
