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.

Relative sea‐level trends in southern Norway during the last millennium
Boreas, EarlyView.Relative sea level in southern Norway has been falling since c. 7000 cal. yr BP, but modern tide gauge data show rising relative sea level since at least 1960 CE. In this study, peat cores from a shallow coastal basin were analysed, using a multiproxy approach, to reconstruct relative sea level trends over the last millennium and to identify the onset ...

Boreas, EarlyView.We have mapped a 60 km long, 30 km wide, 120 m deep buried glacially eroded trough on the North Sea Plateau, west of the Norwegian Channel (59°N, 3°E). The trough was carved out by an ice stream that flowed out from western Norway and crossed the Norwegian Channel in a southwestern direction during the penultimate or Saalian glaciation.

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 ...

Boreas, EarlyView.This study presents a detailed investigation of the Velika Vrbica loess‐palaeosol sequence, situated in the Wallachian Basin of northeastern Serbia, with the aim to reconstruct palaeoenvironmental changes spanning Marine Isotope Stages (MIS) 3 to 1. Using optically stimulated luminescence (OSL) dating, low field magnetic susceptibility (χlf), and mass ...
