Shore ice forms along beaches in cold climates and during its formation is capable of entraining sediment from the nearshore. Upon breakup, entrained sediment within the ice can be rafted to deeper waters, melt out and ...

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 ...

Deformation of subglacial sediment during basal slip shapes the beds of many fast-flowing glaciers and ice streams. The resultant sediment flux impacts glacier dynamics and rates of subglacial erosion over a range of ...

Glacier slip facilitates fast glacier flow and modulates sea-level rise, but empirical constraints on slip-controlling processes at relevant scales are limited. Modern slip rules often assume debris-free basal ice and ...

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 ...

Proglacial digital elevation models (DEMs) from the Swiss Alps and the Canadian Rockies.

The water level in Lake Michigan began rising in 2013. Historically, erosion of the bluffs along the shoreline increases when water levels rise and remain high, beginning at the toe and propagating upslope, potentially ...

High water levels in the Laurentian Great Lakes are causing widespread erosion of unlithified coastal bluffs and damaging infrastructure. Measurements of bluff recession along Wisconsin’s Lake Michigan coast are mostly ...

Drumlin shape has been hypothesized to correlate with ice flow duration and slip speed, but modern-day analogs and the Coulomb nature of till render the basis of these correlations in question. The evolution of flow-parallel ...

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 ...
