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.

The morphosedimentary record of glacial to postglacial environmental changes in West Wiyâshâkimî impact crater lake and adjacent areas, northern Québec, Canada

open access: yesBoreas, 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

open access: yesBoreas, 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.
