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.

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 ...

The role of shallow banks and marine ice domes in marine‐based ice‐sheet deglaciation
Boreas, EarlyView.Marine‐based ice sheets are susceptible to collapse and faster retreat than their land‐terminating counterparts. One of the key factors contributing to the relative stability of marine‐terminating ice sheets is the presence of shallow bathymetric banks and islands acting as pinning points for the ice sheet.

Luminescence analysis of a postglacial landscape in northeastern Norway and northern Finland
Boreas, EarlyView.Portable optically stimulated luminescence (pOSL) analysis allows rapid relative dating of sediments that potentially can be calibrated against known OSL ages to provide an age estimate for landforms across a large area. This study uses 186 pOSL measurements and 20 OSL ages to investigate the postglacial landscape evolution inside the Younger Dryas ...

Boreas, EarlyView.Low‐relief dry channels appear out of place across a glaciated karst landscape in northern Ohio. Channels are only a few metres deep cut into limestone and draped with a veneer of till. Several hypotheses are proposed for explaining the channels. Low‐relief dry channels are observed across the Bellevue‐Castalia Karst Plain of north‐central Ohio, USA ...
