Automated X‐ray computed tomography‐based analysis of clast fabric in drill‐cores of glacial diamicts using deep learning models

Boreas, EarlyView.
Clast‐fabric analysis is a widely used method for investigating depositional and deformation processes in glacial sediments. However, traditional field‐based approaches lack standardization, are time consuming and introduce sampling bias. This study aimed to develop a novel approach to automate clast‐fabric analysis using machine learning‐based image ...

Shoreline and deglaciation chronology in southeast Norway

Boreas, EarlyView.
The postglacial relative sea level history is reconstructed in four areas of mid‐ and inner Oslofjorden in southeast Norway. The reconstructions are based on radiocarbon‐dated raised shoreline levels from 42 sites, mainly isolation basins, and limiting ages from four lakes above the marine limit.

Use of LiDAR to derive a new model of glacial hydro‐dynamic events shaping southern Ontario landscapes, Canada

Boreas, EarlyView.
High‐resolution LiDAR data with field validation of inferred southern Ontario ice stream terrains indicate that steady‐state ice streaming is difficult to reconcile with our observations. Rather, these new observations show strong evidence of significant fluvial scouring across the area in which meltwater sheet flow overtopped the landscape.

Morphology and sedimentology of murtooized terrain on the southern Fraser Plateau, British Columbia, Canada

Boreas, EarlyView.
Recent public releases of Light Detection and Ranging (LiDAR) data in south central British Columbia (BC), Canada have revealed several landforms resembling ‘murtoos’, previously identified across portions of Scandinavia. In this study, we investigate the morphology and sedimentology of these landforms, the first report of their kind associated with ...
