Modelling of hydrological response to climate change in glacierized Central Asian catchments [PDF]

open access: yes, 2007
The arid lowlands of Central Asia are highly dependent on the water supplied by the Tien Shan mountains. Snow and ice storage make large contributions to current runoff, particularly in summer.

Multi‐Habitat Landscape Promotes Microbial Diversity: Insights from the Traditional Agricultural Heritage and the Global Trend

open access: yesAdvanced Science, EarlyView.
The 2500‐year‐old Mulberry‐dyke and Fish‐pond agricultural heritage system reveals how interconnected habitats foster microbial diversity. Multi‐habitat landscapes enhance microbial diversity through cross‐habitat dispersal and adaptive trait convergence. Globally, regions with diverse habitats support a greater diversity of soil microbiomes.

Development of Petrov glacial-lake system (Tien Shan) and outburst risk assessment

open access: yesЛëд и снег, 2015
Global climate warming causes an intensive melting and retreat of glaciers in the Tien Shan mountains. Melting water of glaciers causes overfilling of high mountain lakes.

Glacier changes in the Bavarian Alps from 1989/90 to 2006/07 [PDF]

open access: yes, 2008
The five glaciers in Bavaria which today cover a total area of less than one square kilometer were frequently monitored by geodetic methods from the mid of the 20th century. In this paper, the record is extended by new surveys in 1999 and 2006.

Changes of Marukh Glacier from 1945 to 2011

open access: yesЛëд и снег, 2015
Field studies have been carried out in summer 2011 at Marukh Glacier located in western part of the Northern Caucasus. The studies included ground-based radio-echo sounding measurements at a frequency of 20 MHz and glacier surface elevation survey using ...

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

Origin and significance of 'dispersed facies' basal ice: Svínafellsjökull, Iceland [PDF]

open access: yes, 2010
Dispersed facies basal ice - massive (i.e. structureless) ice with dispersed debris aggregates - is present at the margins of many glaciers and, as a product of internal glacial processes, has the potential to provide important information about the ...

Thinned and Welded Silver Nanowires for Intelligent Pressure and Humidity Sensing Enabled by Machine Learning

open access: yesAdvanced Science, EarlyView.
Thinned and welded silver nanowires are prepared by selectively engineering their morphology and structure. The resulting films show enhanced optical, electrical, thermal, and mechanical properties. By incorporating machine learning, the developed pressure and humidity sensors are able to accurately identify finger pressing behaviors, monitor human ...
