The role of inland ice dynamics in controlling the variable maximum extent of the Laurentide Ice Sheet off southeastern Baffin Island

Boreas, EarlyView.
Reconstructions of the maximum extent of the Laurentide Ice Sheet (LIS) and its associated ice flows at the Last Glacial Maximum (LGM) are needed for understanding how marine‐based ice sheets will respond to modern climate change. Here, we provide evidence for the location of the maximal extent of the LIS margin during the LGM in Merchants and ...

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 ...

Complex past ice flow from Norway to the North Sea Plateau during the Quaternary: evidence from Marstein Trough and earlier reconstructions using 3D seismic data sets

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.

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 ...
