Permafrost Distribution in the Canadian Rockies: Key Variables Influencing Patch‐Scale Variability

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT The spatial distribution of permafrost in mountainous regions is influenced by various factors such as topography, climate, vegetation, and substrate. Despite the existence of comprehensive permafrost maps at national and global levels, they fail to accurately represent the patch‐scale (e.g., < 25 m) permafrost distribution in characteristic ...

The Age and Origin of Block Deposits in the Victorian Alps, Australia

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Large periglacial block deposits are found in the mountains of southeastern Australia. Despite their widespread distribution, their mode of formation and age are poorly understood. These landforms hold considerable potential to shed light on the nature of cooling during glacial periods. In this paper we present a new study of block deposits in

Deciphering Freeze–Thaw Dynamics In Rockwalls: A Novel Approach for High Accuracy Regional‐Scale Modeling

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Using a large and novel array of instruments on five rockwalls in northern Gaspesia, their respective surface energy balances were calculated and their thermal regimes were measured and modeled to depths exceeding the seasonal frost penetration.

Current Status, Problems and Solution Proposals of Small Ruminant Husbandry in Ordu

Turkish Journal of Agriculture: Food Science and Technology, 2016
The Black Sea Region has a convenient structure for small ruminants in livestock activities thanks to its mountainous, rugged terrain, climate and socio-economic structure. Ordu is the third largest city of the Black Sea Region.

Elevation Filters Lizard Species Occurrences and Assemblages in Chitwan Annapurna Landscape, Nepal. [PDF]

Ecol Evol
We investigated lizard species richness,assemblage patterns, and environmental drivers along the elevational gradient in the Chitwan Annapurna Landscape during 2018–2019. We recorded 23 lizard species and found that species richness varied significantly and non‐linearly with elevation, peaking at mid elevation. Species turnover dominated beta diversity,

Capturing the Multi‐Decadal Evolution of Glacier–Permafrost Interactions in a High‐Alpine Environment (Ritord, Western Swiss Alps)

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT This study investigates the multi‐decadal evolution of a glacier forefield under permafrost conditions in the Combins Massif (western Swiss Alps). A multi‐method approach based on historical and recent datasets is used to analyze its landform components.

Practical LAI Estimation with DHP Images in Complex Forest Structure with Rugged Terrain

, 2023
Leaf area index is a key structural parameter for biological and physical processes. Korea is planning to launch CAS500-4 in 2025, so in situ data is needed to validate the leaf area index.

“Cold Tropics”: Permafrost Existence and Thickness on Eastern Nevado Coropuna (Southern Peruvian Andes) Revealed by Ground‐Penetrating Radar and Geoelectrical Soundings

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT The existence of permafrost was explored at tropical latitude on Nevado Coropuna (southern Peruvian Andes) using a combination of ground‐penetrating radar (GPR) and vertical electrical sounding (VES) in order to strengthen the mutual validation of data processing and interpretation.

A Stepwise BRDF-Based Land Surface Reflectance Model Over Rugged Terrain

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
The land surface reflectance is an essential variable of remote sensing, which is significantly affected by topography and atmosphere. Rugged terrain significantly alters the radiative transfer among the solar-terrain-sensor, resulting in large errors in
