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

Boreas, 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.

An inventory of subglacial overdeepenings in southern Germany and Austria

Boreas, EarlyView.
We present an inventory and morphometric characterization of >100 individual overdeepened basins in southern Germany and Austria compiled from heterogeneous sources. Arrangement and dimensions of overdeepenings are compared to those of their western Alpine counterparts, to catchment topographies and bedrock lithologies, and to modelled ice‐flow ...

Mineralogy and composition of Archean Crust, Greenland: A pilot study [PDF]

The Portable Instant Display and Analysis Spectrometer (PIDAS) was taken to southwestern Greenland to investigate in situ the potential application of AVIRIS to estimate the mineralogy and composition of rocks exposed in Archean terranes. The goal was to

The role of shallow banks and marine ice domes in marine‐based ice‐sheet deglaciation

Boreas, 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.
