Thermokarst Lagoons: Distribution, Classification and Dynamics in Permafrost‐to‐Marine Transitions
Permafrost and Periglacial Processes, EarlyView.ABSTRACT The transition of permafrost landscapes to marine environments, driven by climate change, plays a crucial role in the global carbon cycle. Thermokarst lagoons, formed along permafrost coasts when thermokarst lakes get connected to the sea, are key features in this transition.

Remote Sensing, 2019 Marine-terminating glaciers dominate the evolution of the Greenland Ice Sheet (GrIS) and its contribution to sea-level rise. Widespread glacier acceleration has been linked to the warming of ocean waters around the periphery of Greenland but a lack of ...

Impact of the International Glaciological Society on the development of glaciology and its future role [PDF]
Journal of Glaciology, 1987 AbstractAfter the end of World War II glaciology entered a new golden age, which has yet to end. The quality of this golden age is comparable to the classic period of the nineteenth century. The International Glaciological Society has been the major catalyst, through its very active and co-operative international membership and its Journal of ...

Quarterly Journal of the Royal Meteorological Society, EarlyView.This study analyzed the impact of two mesoscale cyclones on the meteorology and glaciology of South Shetland Islands (SSI) glaciers, using in‐situ observations, ERA5 reanalysis data, and high‐resolution weather and glacier mass balance models. Mesoscale cyclones drive temperature drops, heavy snowfall, and strong winds over the SSI, significantly ...

Boreas, EarlyView.Environmental changes on the northern part of Taymyr Peninsula during the last 62 ka were reconstructed based on pollen assemblages throughout a 46‐m‐long sediment core from Lake Levinson‐Lessing (74°27′54″N, 98°39′58″E). Environmental changes on the northern Taymyr Peninsula were reconstructed based on a new pollen record from a 46‐m‐long sediment ...

Weichselian–Holocene glacial history of the Sjuøyane archipelago, northern Svalbard
Boreas, EarlyView.To reconstruct the glacial history of Sjuøyane, we describe coastal sedimentary sections in Quaternary sediments and constrain their chronology by radiocarbon and optically stimulated luminescence ages. The sedimentary sections largely consist of shallow (glacio‐)marine and/or littoral sediments deposited during high relative sea levels.

Boreas, EarlyView.Morphometric values of streamlined subglacial bedforms provide valuable information about the relative speed, direction, and maturity of past ice streams. This paper presents a new tool that utilizes a machine learning approach to automatically identify glacially derived streamlined features.

Geometrical force balance in glaciology [PDF]
Journal of Geophysical Research: Solid Earth, 2003 The analytical force balance traditionally used in glaciology relates gravitational forcing to ice surface slope for sheet flow and to ice basal buoyancy for shelf flow. It is unable to represent stream flow as a transition from sheet flow to shelf flow by having gravitational forcing gradually passing from being driven by surface slope to being driven
