Abrasion acts to smooth glacial terrains and leaves behind linear scratch-like features (striations) on bedrock landscapes. Striations are often used as measures of glacier flow directions, but their morphology can provide ...

While analysis of glacial seismicity continues to be a widely-used method for interpreting subglacial processes, the underlying mechanics controlling basal stick-slip seismicity remain speculative. Here, we report on ...

Subglacial till can deform when overriding ice exerts shear traction at the ice-till interface. This deformation leaves a strain signature in the till, aligning grains in the direction of ice flow and producing a range of ...

Glacial landforms provide a valuable record from which to study the history and dynamics of past ice sheets. Eskers record paleo subglacial hydrologic and sediment transport conditions because they are composed of sediment ...

Glacial kettles are surficial depressions that form in formerly glaciated terrain when buried stagnant ice melts within proglacial sediments, often deposited by meltwater streams. Kettles, like other glacial landforms, ...

Fast ice affects many coastlines in high- and mid-latitude regions, shaping the coastal morphology by acting as both a protective barrier from winter storms and as an erosive agent through sediment entrainment and transport. ...
