Distribution and UV protection strategies of zooplankton in clear and glacier-fed alpine lakes

open access: yesScientific Reports, 2017
Zooplankton, a group of aquatic animals important as trophic link in the food web, are exposed to high levels of UV radiation (UVR) in clear alpine lakes, while in turbid glacier-fed lakes they are more protected.

RHEOLOGY OF GLACIER ICE

open access: yesLe Journal de Physique Colloques, 1985
A new method for calculating the stress field in bounded ice shelves is used to compare strain rate and deviatoric stress on the Ross Ice Shelf, Antarctica. The analysis shows that strain rate (per second) increases as the third power of deviatoric stress (in newtons per square meter), with a constant of proportionality equal to 2.3 x 10

Spatiotemporal dynamic characteristics of typical temperate glaciers in China

open access: yesScientific Reports, 2021
China’s temperate glaciers have a relatively warm and humid climate and hydrothermal conditions at low latitudes. Temperate glaciers, however, have larger ablation, higher ice temperatures, relatively fast movement speeds, and a significant sliding ...

Electron microprobe dating of lunar zirconolite

open access: yesJournal of Analytical Science and Technology
Zirconolite is an accessary mineral occurred in the lunar basaltic and granitic rocks and contains relatively high contents of U, Th, and Pb, which is attractive for age dating.

Characterizing vegetation and return periods in avalanche paths using lidar and aerial imagery

open access: yesArctic, Antarctic, and Alpine Research
Snow avalanches are a hazard and ecological disturbance across mountain landscapes worldwide. Understanding how avalanche frequency affects forests and vegetation improves infrastructure planning, risk management, and avalanche forecasting.

Mountain glacier-to-rock glacier transition

open access: yesGlobal and Planetary Change, 2019
Abstract In many of the world's high mountain systems, glacier recession in response to climate change is accompanied by a paraglacial response whereby glaciers are undergoing a transition to rock glaciers. We hypothesise that this transition has important implications for hydrological resources in high mountain systems and the surrounding lowlands ...

Glacier area and the variability of glacier change

open access: yes, 2019
This is the preprint of a letter that is under review in the Journal of Glaciology. The abstract is as follows: Large-scale remote-sensing data on ice loss in the Himalaya and other glacierised regions indicate that the differences in glacier area do not significantly influence the glacier-to-glacier variability of the thinning rate. An analysis of the
