Earth Surface Processes and Landforms, Volume 51, Issue 2, February 2026.We provide a geomorphological analysis of Cordillera Vilcanota and use morphostratigraphic principles to reconstruct palaeo icefield extent and palaeoglacier readvances, likely during the Antarctic Cold Reversal and Younger Dryas. We find evidence of temperate and polythermal ice margins, with limited glaciofluvial landform generation.

Permafrost and Periglacial Processes, Volume 37, Issue 1, Page 78-106, January/March 2026.ABSTRACT The aim of this work is to study a variety of glacial, periglacial and paraglacial features found in a small cirque, Fremri‐Grasárdalur, in Tröllaskagi (Northern Iceland). We implement a multidisciplinary approach combining high‐resolution geomorphological mapping, horizontal/vertical boulder displacement (from 1994 to 2019) and surface ...

Estimating the Age and Mechanism of Boulder Transport Related with Extreme Waves Using Lichenometry [PDF]
, 2020 Tsunamis and storms cause considerable coastal flooding, numerous fatalities, destruction of structures, and erosion. The characterization of energy and frequency associated with each wave contribute to the risk assessment in coastal regions.

Rapid mass movements triggered by an atmospheric river in Disko Island, West Greenland
Earth Surface Processes and Landforms, Volume 50, Issue 15, December 2025.In early July 2023, a series of rapid mass movements was triggered by extreme precipitation carried by an atmospheric river in Disko Island, West Greenland. During 18 h total precipitation reached up to 115 mm, causing more than 150 slushflows in different areas of the island and substantial damage to some infrastructure close to the Qeqertarsuaq ...

Rock Glacier Velocity: An Essential Climate Variable Quantity for Permafrost
Reviews of Geophysics, Volume 63, Issue 1, March 2025.Abstract Rock glaciers are distinctive debris landforms found worldwide in cold mountainous regions. They express the long‐term movement of perennially frozen ground. Rock Glacier Velocity (RGV), defined as the time series of the annualized surface velocity of a rock glacier unit or a part of it, has been accepted as an Essential Climate Variable ...

Journal of Flood Risk Management, Volume 17, Issue 3, September 2024.Abstract Extremely rapid rates of rise in level and discharge in a subset of flash floods (‘abrupt wave front floods’, AWF) are separate hazards from peak level. Such flood events are investigated for Pennine catchments in northern England using both gauged and historical information.

Accelerating Glacier Area Loss Across the Andes Since the Little Ice Age
Geophysical Research Letters, Volume 51, Issue 13, 16 July 2024.Abstract Andean glaciers are losing mass rapidly but a centennial‐scale context to those rates is lacking. Here we show the extent of >5,500 glaciers during the Little Ice Age chronozone (LIA; c. 1,400 to c. 1,850) and compute an overall area change of −25% from then to year 2000 at an average rate of −36.5 km2 yr−1 or −0.11% yr−1.

Dating Exposed Rock Surfaces in the Arctic by Lichenometry: The Problem of Thallus Circularity and Its Effect on Measurement Errors [PDF]
, 1985 . Lichenometry represents an extremely useful dating technique in the Arctic. It is most appropriate for exposed rock surfaces, which are abundant in most arctic environments, and on occasion it represents the only suitable technique for estimating the ...

Acceleration of Abramov Glacier (Pamir‐Alay) retreat since the Little Ice Age
Boreas, Volume 53, Issue 3, Page 415-429, July 2024.The Abramov Glacier, situated in the Koksu River valley in the Pamir‐Alay Mountain range, was extensively monitored from 1965 to 1999 and again since 2011, providing valuable climate data. We apply cosmogenic 10Be exposure datings, ground penetrating radar measurements combined with numerical modelling as well as calculation of secular glacier mass ...
