Thermo-erosion gullies (TEGs) are one of the most common forms of abrupt permafrost degradation. While their inception has been examined in several studies, the processes of their stabilization remain poorly documented. For this study, we investigated two TEGs in the Canadian High Arctic. We found that, while the formation of a TEG leaves permanent geomorphological scars in landscapes, in the long term, permafrost can recover to conditions similar to those pre-dating the initial disturbance.

We attempt to enhance the current diagnostic criteria for channels formed under ice sheets by applying mathematical relationships commonly used to describe the correlation between river size and discharge. Our analysis reveals a unique relationship between channel size and drainage area size, which we have interpreted to represent formation under an ice sheet. These relationships can be applied to extremely remote environments to discuss glaciation in locations with accessibility constraints.

Rivers with alternating patterns of shallow and deep flows are commonly observed where a river widens and then narrows, respectively. But what if width changes over time? We use a lab experiment to address this question and find it is possible to decrease and then increase river width at a specific location and observe that flows deepen and then shallow consistent with expectations. Our observations can inform river restoration and climate adaptation programs that emphasize river corridors.

Sediment particles are transported along the bottom of rivers during floods. Descriptions of the transport process are commonly restricted to the strength of the water flow. In our research we use mathematical theory and data from laboratory experiments to explore whether sediment particles colliding with the river bed can help explain our observations of transport. We learn that particle collisions are likely an important component of the transport process and we offer thoughts for future work.

The primary goal of this paper is to present a model of snow surface albedo (brightness) accounting for small-scale surface roughness effects. It can be combined with any volume scattering model. The results indicate that surface roughness may decrease the albedo by about 1–3 % in midwinter and even more than 10 % during the late melting season. The effect is largest for low solar zenith angle values and lower bulk snow albedo values.

Water accumulated at the base of ice sheets is the main driver of glacier acceleration and loss of ice mass in Arctic regions. Previously glaciated landscapes sculpted by this water carry information about how ice sheets collapse and ultimately disappear. The search for these landscapes took us to the high Arctic, to explore channels that formed under kilometers of ice during the last ice age. In this work we describe how subglacial channels look and how they helped to drain an ice sheet.

This paper analyses the timing of topographical changes of a gravel bed ephemeral river channel during consecutive and moderate- and low-magnitude floods by applying a morphodynamic model calibrated with pre- and post-event surveys using RTK-GPS and mobile laser scanning. The channel acted as a braided river during lower flows but as a meandering river during higher flows. The channel changes can be greater during the long-lasting receding phase than during the rising phase of the floods.

Bowl-shaped ice-wedge polygons in permafrost regions can retain snowmelt water and moisture in their center. On Bylot Island (NU, CA), a rapidly developing thermal erosion gully eroded the polygons' ridges, impacting the polygon centers' ground moisture and temperature, plant cover and species. An intact polygon was homogeneous in its center for the aforementioned elements, whereas eroded polygons had a varying response following the breach, with heterogeneity as their new equilibrium state.

Understanding the history and drivers of Greenland Ice Sheet change is important to forecast future ice sheet retreat. We combined geologic mapping and cosmogenic nuclide measurements to investigate how the Greenland Ice Sheet formed the landscape of Inglefield Land, northwest Greenland. We found that Inglefield Land was covered by warm- and cold-based ice during multiple glacial cycles and that much of Inglefield Land is an ancient landscape.

Short summary
Sediment transport in rivers and under glaciers depends on water velocity and channel width. In rivers, water discharge changes affect flow depth, width, and velocity. Under glaciers, pressurized water changes velocity more than shape. Due to these differences, this study shows that sediment transport under glaciers varies widely and peaks before water flow does, creating a complex relationship. Understanding these dynamics helps interpret sediment discharge from glaciers in different climates.

The extent to which Greenland's peripheral glaciers and ice caps current and future ice loss rates are unprecedented within the Holocene is poorly understood. This study connects the maximum ice extent of the Late Holocene with present and future glacier evolution in the Nuussuaq Peninsula (Central-Western Greenland). By > 2070 glacier mass loss may double the rate from the Late Holocene to the present, highlighting significant impacts of anthropogenic climate change.

Glacial erosion is a fundamental process operating on Earth's surface. Two processes of glacial erosion, abrasion and plucking, are poorly understood. We reconstructed rates of abrasion and quarrying in Greenland. We derive a total glacial erosion rate of 0.26 ± 0.16 mm per year. We also learned that erosion via these two processes is about equal. Because the site is similar to many other areas covered by continental ice sheets, these results may be applied to many places on Earth.

Moraine is an awe-inspiring landscape in alpine areas and stores information on past climate. We measured the timing of moraine formation on the Ih Bogd Massif, southern Mongolia. Here, glaciers move synchronously as a response to changing climate; however, our glacier on the northern slope reached its maximum extent 3 millennia after the southern one. We ran a 2D ice surface model and found that the diachronous behavior of glaciers was real. Aspect also controls the mass of alpine glaciers.

Glacier tables are structures frequently encountered on temperate glaciers. They consist of a rock supported by a narrow ice foot which forms through differential melting of the ice. In this article, we investigate their formation by following their dynamics on the Mer de Glace (the Alps, France). We explain this phenomenon by a combination of the effect of turbulent flux, short-wave flux and direct solar radiation that sets a critical size above which a rock will form a glacier table.

Eastern Alpine glaciers have been receding since the Little Ice Age maximum, but until now the majority of glacier margins could be delineated unambiguously. Today the outlines of totally debris-covered glacier ice are fuzzy and raise the discussion if these features are still glaciers. We investigated the fate of glacier remnants with high-resolution elevation models, analyzing also thickness changes in buried ice. In the past 13 years, the 46 glaciers of Silvretta lost one-third of their area.

We use high-resolution satellite imagery and field visits to assess the growth and drainage of a lake on Changri Shar Glacier in the Everest region, and its impact. The lake filled and drained within 3 months, which is a shorter interval than would be detected by standard monitoring protocols, but forced re-routing of major trails in several locations. The water appears to have flowed beneath Changri Shar and Khumbu glaciers in an efficient manner, suggesting pre-existing developed flow paths.

Short summary
This study investigates enigmatic ring forms found on Axel Heiberg Island (Umingmat Nunaat) in Nunavut, Canada. These ring forms comprised a series of ridges and troughs creating individual rings or brain-like patterns. We aim to identify how they form and assess the past climate conditions necessary for their formation. We use surface and subsurface observations and comparisons to other periglacial and glacial ring forms to infer a formation mechanism and propose a glacial origin.
