Boreas, Volume 55, Issue 3, Page 670-701, July 2026.Rapid thaw of the Earth's cryosphere in response to anthropogenic warming highlights the need to identify and understand the contrasting signatures of past ice‐sheet stability and collapse. The Kvarken archipelago, western Finland, at the centre of the former Fennoscandian Ice Sheet (FIS), has been designated a UNESCO World Heritage site in recognition

An integrated Structure-from-Motion and time-lapse technique for quantifying ice-margin dynamics
Journal of Glaciology, 2017 Fine resolution topographic data derived from methods such as Structure from Motion (SfM) and Multi-View Stereo (MVS) have the potential to provide detailed observations of geomorphological change, but have thus far been limited by the logistical ...

Climate Warming and Ice Weakening Trigger Alpine Glacier Collapses: The Marmolada Case
Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.Abstract The rapid retreat of temperate mid‐latitude glaciers due to global warming causes dramatic mass loss and increases their instability. Using a synthesis of thermodynamic and mechanical laws, we constructed a three‐dimensional stability model and applied it in the analysis of the collapse of a portion of the Marmolada Glacier in northeastern ...
