De Geer moraine internal architecture based on sedimentological and geophysical investigations and implications for ice‐marginal reconstructions

Boreas, EarlyView.
De Geer moraines may act as valuable ice‐marginal indicators; however, to date, their variable mode of formation has presented challenges for this utility. Here, we present sedimentological and ground penetrating radar data of DGMs located in southwest Finland.

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 ...

Subglacial landscape formation and sediment discharge: relating basal conditions to bedform dimensions and properties at Rutford Ice Stream, West Antarctica

Boreas, EarlyView.
Basal conditions that facilitate fast ice flow are still poorly understood and their parameterization in ice‐flow models results in high uncertainties in ice‐flow and consequent sea‐level rise projections. Direct observations of basal conditions beneath modern ice streams are limited due to the inaccessibility of the bed.

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 ...
