A thermomechanical model for frost heave and subglacial frozen fringe [PDF]
Journal of Fluid Mechanics, 2021 Ice-infiltrated sediment, or frozen fringe, is responsible for phenomena such as frost heave, ice lenses and metres of debris-rich ice under glaciers. Understanding frozen fringes is important as frost heave is responsible for damaging infrastructure at ...

Geophysical Monograph Series, Page 117-131., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Debris-bed friction during glacier sliding with ice–bed separation
Annals of Glaciology, 2019 Theory and experiments indicate that ice–bed separation during glacier slip over 2-D hard beds causes basal shear stress to reach a maximum at a particular slip velocity and decrease at higher velocities.

Subglacial landforms beneath Rutford Ice Stream, Antarctica: detailed bed topography from ice-penetrating radar [PDF]
Earth System Science Data, 2016 We present a digital elevation model of the bed of Rutford Ice Stream, Antarctica, derived from radio-echo sounding data. The data cover an 18 × 40 km area immediately upstream of the grounding line of the ice stream.

Prospects of obtaining samples of bottom sediments from subglacial lake Vostok
Записки Горного института, 2017 The paper proves the timeliness of obtaining and examining bottom sediments from subglacial Lake Vostok. Predictive geological section of Lake Vostok and information value of bottom sediments have been examined.

The life and death of a subglacial lake in West Antarctica
Geology, 2023 Over the past 50 years, the discovery and initial investigation of subglacial lakes in Antarctica have highlighted the paleoglaciological information that may be recorded in sediments at their beds.

FEMS Microbiology Ecology, 2018 Microbes transported by glacial meltwater streams are thought to be a product of passive dispersal from both supra‐ and subglacial sources, though studies investigating the origins of these assemblages are scarce.

Bed-type variability and till (dis)continuity beneath Thwaites Glacier, West Antarctica
Annals of Glaciology, 2019 Recent seismic measurements from upper Thwaites Glacier indicate that the bed-type variability is closely related to the along-flow basal topography. In high-relief subglacial highlands, stoss sides of topographic highs have a relatively higher acoustic ...

Journal of Glaciology, 2023 We use a mathematical model to investigate the effect of basal topography and ice surface slope on transport and deposition of sediment within a water-filled subglacial channel. In our model, three zones of different behaviour occur. In the zone furthest
