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.

“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.
