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 ...

Palaeoenvironmental changes recorded at the Velika Vrbica loess‐palaeosol sequence, Wallachian Basin, during MIS 3–MIS 1

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 ...

Multiple indicators record human adaptations to climatic change during the Middle Holocene at the Wanbei site in the middle and lower Huai River valley, China

Boreas, EarlyView.
The archaeological sediment sequences analysis from the Wanbei site reveals a predominantly warm and humid climate with a brief cooling phase between 5600 and 5400 a BP, during the Middle Holocene in the middle and lower Huai River valley. Despite the cooling trend, rice remained the dominant crop in mixed farming, while the proportion of millet ...
