We describe the morphological characteristics of anastomosing (labyrinthine) bedrock channels to enhance the current understanding of subglacial meltwater dynamics of the Innuitian Ice Sheet. Our work reveals a morphological similarity between labyrinthine channels and other landscapes modified by glacial floods. We argue that the presence of anastomosis, distinct erosional surfaces, and longitudinal profile slope breaks imply formation by short-lived episodes of erosion associated with floods.

We present field measurements collected during the Finnish Antarctic Research Program (FINNARP) 2022 expedition at Aboa station in Dronning Maud Land, Antarctica. Weekly observations were taken at the automatic weather station site and at selected overpass locations of two satellites. The dataset includes continuous meteorological records, snow pit profiles, ground- and drone-based radiation measurements, and snow surface roughness from laser scans.

We study how Arctic rivers respond to rainfall in a warming climate. We show that runoff response can increase more than 5x under wetter conditions, and Active Layer Detachments amplify water and material runoff response to rainfall. Increasing subsurface storage can reduce runoff sensitivity to rainfall. Our results inform the flashiness of rainfall-runoff predictions based on expected weather and erosion conditions.

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.

Short summary
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.

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.
