Imaging the firn of the Antarctic ice sheet with traffic noise
The firn layer in the upper part of the Antarctic ice sheet represents a crucial transitional zone during the transformation from snow to glacial ice, and its structural characteristics play an essential role in evaluating the surface mass balance of the

Rapid Increase in Geogenic CO2 Emissions from Antarctic Permafrost
Abstract Thawing permafrost can amplify climate change by releasing previously stored carbon, but observations of this feedback come mainly from the Arctic. Ice‐free Antarctic terrains are generally regarded as minor CO2 sources, although sub‐permafrost brines and deep carbon reservoirs may support localized geogenic degassing.

Abstract The Mars 2020 mission has explored depositional environments recorded in a fan‐shaped deposit on the western side of Jezero crater. Kodiak butte is an isolated outcrop of sedimentary rock ∼1 km south of the western fan scarp and may be an erosional remnant of said fan.

The Dinaric Mountains are a mountain range stretching NW–SE from the Alps to the Albanides–Hellenides in central Europe. The highest parts were occupied by small ice fields and/or valley glaciers during the Quaternary cold periods, while even today some small glaciers still exist in topoclimatically favourable areas.

Truncated drumlins and their implication for past sea level reconstructions
Coastal erosion of glacigenic sediments, particularly in the form of retreating drumlin bluffs, is a key process in paraglacial landscape evolution during periods of relative sea‐level (RSL) rise. As marine transgression reworks formerly subaerial glacial terrains, drumlins act as discrete sediment sources generating characteristic erosional and ...

Preliminary analysis of life within a former subglacial lake sediment in Antarctica [PDF]
Since the first descriptions of Antarctic subglacial lakes, there has been a growing interest and awareness of the possibility that life will exist and potentially thrive in these unique and little known environments. The unusual combination of selection

Abstract Understanding the coastal zone of the Antarctic Ice Sheet (AIS), where it interacts with the Southern Ocean and warmer air masses, is crucial for predicting Antarctica's influence on the global climate and sea level. This region has multiple tipping mechanisms that could trigger large, rapid, and potentially irreversible changes in the AIS ...
