The state of the Shapshalsky glacierization center (Eastern Altai) in 2015

Лëд и снег, 2021
Catalogues and maps of glaciers (for 2015) of Shapshal Glacier Center, located in the eastern part of the Russian Altai, have been created based on the first field glaciological observations and space images interpretation. In total 123 glaciers with the

Mountain glaciers: on thinning ice

, 2014
Mountain glaciers are key indicators of climate change. Glacier changes are the most visible evidence of global climate change we have. They affect the appearance of the landscape in high mountains and impact regional water supplies, local hazard conditions and global sea levels.

Evaluating Testability of Permafrost Models Through Physical and Thermal Testing in Complex Mountain Terrain, Yukon, Canada

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Due to its subsurface nature, permafrost cannot be directly observed with the naked eye or optical remote sensing. Consequently, accurately describing its distribution and thermal state is challenging. This is especially true in vast, remote environments, where obtaining comprehensive field data is demanding or improbable.

The glacier of the Leonese Cantabrian Mountains

, 2022
[EN] The Montes de León are located in the northwest part of the Iberian Peninsula. They extend approximately 65 km, from the Sil River (Min˜o-Sil Basin) in the west, to the Orbigo River (Douro Basin) to the east. They consist of two main alignments: the northernmost, in a north-northwest to south-south-east direction, is formed by the Aquilanos ...

Repeated Pleistocene Permafrost Episodes in the Western Pannonian Basin

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Concerning the study of past periglacial processes, the Pannonian Basin is a key area as it contains the southernmost frost polygons found in Central Europe. The presence or absence of permafrost is still, however, a matter of debate, and data on the timing of frost action are also scarce.

Internal Permafrost Structure of Geomorphologically Distinct Palsas in Northern Sweden Revealed by Quasi‐3D ERT

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Permafrost in northern peatlands occurs within individual palsas or extensive peat plateaus and controls local carbon storage. These permafrost landforms are complex, and their internal structure remains poorly understood. We used quasi‐3D electrical resistivity tomography (ERT) measurements, supported by UAV‐LiDAR topography, frost probing ...

Depositional and Hydrological Relationships Between Buried Dead Ice and the Active Layer in the McMurdo Dry Valleys, Antarctica: A Study of Sediment Geochemistry and Cation Concentrations

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT The McMurdo Dry Valleys, the largest ice‐free region in Antarctica, are home to a cold‐desert hydrologic system of glaciers, snowbanks, streams, and lakes. Freshwater is also stored as dead glacial ice, which is poorly constrained in terms of ion concentrations and interactions with both in situ and overlying sediments.

Evidence of an active glacier in the Munzur Mountains, eastern Turkey

TURKISH JOURNAL OF EARTH SCIENCES, 2015
The Munzur Mountains were subjected to extensive and repeated glaciations during the Pleistocene. The presence of an active glacier in the region was not verified until this study. Here, we used remote sensing methods to identify and locate the glaciers and verified the activity of the largest glacier in the field.

Using dendroclimatic analysis of exotic deciduous conifers in an arboretum to document tree growth in response to climate change, Northeast Ohio, USA

PLANTS, PEOPLE, PLANET, EarlyView.
Rising temperatures and wetter conditions in the Midcontinent of North America are influencing climate responses in trees. Dendroclimatological analyses of four exotic deciduous conifer species from Secrest Arboretum, Northeast Ohio help identify past, present and future climate‐tree interactions.

TPRoGI: a comprehensive rock glacier inventory for the Tibetan Plateau using deep learning [PDF]

Earth System Science Data
Rock glaciers – periglacial landforms commonly found in high-mountain systems – are of significant scientific value for inferring the presence of permafrost, understanding mountain hydrology, and assessing climate impacts on high-mountain environments ...
