An inventory of subglacial overdeepenings in southern Germany and Austria

Boreas, EarlyView.
We present an inventory and morphometric characterization of >100 individual overdeepened basins in southern Germany and Austria compiled from heterogeneous sources. Arrangement and dimensions of overdeepenings are compared to those of their western Alpine counterparts, to catchment topographies and bedrock lithologies, and to modelled ice‐flow ...

The impact of the structural framework of the North German Basin on Pleistocene tunnel‐valley formation

Boreas, EarlyView.
This study contains a comprehensive regional analysis of the orientations of tunnel valleys, faults and salt structures in the North German Basin, aiming to identify correlations that might indicate a structural control on tunnel‐valley formation. A structural control on tunnel‐valley formation has been repeatedly postulated and correlations have been ...

Subglacial processes at the fringe of the last Scandinavian Ice Sheet in central Poland derived from macro‐ and micro‐sedimentological proxies

Boreas, EarlyView.
Here we report on the properties of a glacial sediment succession including various till facies and some subglacial meltwater deposits from a site in central Poland close to the outermost extent of the Scandinavian Ice Sheet during the last glaciation.

Automated delineation and morphometry of unclassified subglacial bedforms

Boreas, EarlyView.
We present an automated tool for mapping and analysing subglacial bedforms using volumetric obscurance, without classification. Tested on ArcticDEM data, the method produces bedform outlines with 75% correspondence compared to manually digitized maps.

The morphosedimentary record of glacial to postglacial environmental changes in West Wiyâshâkimî impact crater lake and adjacent areas, northern Québec, Canada

Boreas, EarlyView.
Crater lakes in core regions of former ice sheets have the potential to preserve long‐term sedimentary archives that are otherwise rare in glaciated landscapes due to pervasive glacial erosion. Lake Wiyâshâkimî, an impact crater lake located in the inner core of the Québec‐Labrador Dome of the Laurentide Ice Sheet, provides a rare example of such a ...
