Environmental changes on the northern Taymyr Peninsula (Russian Arctic) during the last 62 ka inferred from the lacustrine pollen record

open access: yesBoreas, EarlyView.
Environmental changes on the northern part of Taymyr Peninsula during the last 62 ka were reconstructed based on pollen assemblages throughout a 46‐m‐long sediment core from Lake Levinson‐Lessing (74°27′54″N, 98°39′58″E). Environmental changes on the northern Taymyr Peninsula were reconstructed based on a new pollen record from a 46‐m‐long sediment ...

Weichselian–Holocene glacial history of the Sjuøyane archipelago, northern Svalbard

open access: yesBoreas, EarlyView.
To reconstruct the glacial history of Sjuøyane, we describe coastal sedimentary sections in Quaternary sediments and constrain their chronology by radiocarbon and optically stimulated luminescence ages. The sedimentary sections largely consist of shallow (glacio‐)marine and/or littoral sediments deposited during high relative sea levels.

Automatic identification of streamlined subglacial bedforms using machine learning: an open‐source Python approach

open access: yesBoreas, EarlyView.
Morphometric values of streamlined subglacial bedforms provide valuable information about the relative speed, direction, and maturity of past ice streams. This paper presents a new tool that utilizes a machine learning approach to automatically identify glacially derived streamlined features.

New insights into one of the oldest glacial deposits in the northern Alpine foreland (Höchsten, SW Germany)

open access: yesBoreas, EarlyView.
Diamictic deposits within a presumed Early Pleistocene overdeepened basin are investigated with a combined sedimentological‐geotechnical approach including analysis via μCT scans. Sedimentary facies, geotechnical properties, and microstructures reflect a transition from glacier‐proximal deposition towards direct ice contact and subglacial deformation ...
