Soil wetting and drying processes influence stone artefact distribution in clay‐rich soils: A case study from Middle Gidley Island in Murujuga, northwest Western Australia

open access: yesArchaeometry, EarlyView.
Abstract Soils that contain swelling clay minerals (e.g., montmorillonite) expand and contract during wetting and drying, causing movement within the soil profile. This process, known as argilliturbation, can alter artefact distributions, destroy stratigraphy and complicate the interpretation of archaeological deposits.

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 ...
