Stream hydrology controls on ice cliff evolution and survival on debris-covered glaciers [PDF]
Earth Surface DynamicsIce cliffs are melt hot spots that contribute disproportionately to melt on debris-covered glaciers. In this study, we investigate the impact of supraglacial stream hydrology on ice cliffs using in situ and remote sensing observations, streamflow ...

Array processing in cryoseismology: a comparison to network-based approaches at an Antarctic ice stream [PDF]
The Cryosphere, 2023 Seismicity at glaciers, ice sheets, and ice shelves provides observational constraint on a number of glaciological processes. Detecting and locating this seismicity, specifically icequakes, is a necessary first step in studying processes such as basal ...

Analytical solutions for the surface response to small amplitude perturbations in boundary data in the shallow-ice-stream approximation [PDF]
The Cryosphere, 2008 New analytical solutions describing the effects of small-amplitude perturbations in boundary data on flow in the shallow-ice-stream approximation are presented.

Ice stream behaviour and deglaciation of the Scandinavian Ice Sheet in the Kuittijärvi area, Russian Karelia [PDF]
Bulletin of the Geological Society of Finland, 2008 Glacial landforms of the Lake Kuittijärvi area, Russian Karelia, which covers an area of more than 7000 km2 , were studied in detail using aerial photography and satellite imagery methods and on-site field observations.

The BEAMISH hot water drill system and its use on the Rutford Ice Stream, Antarctica
Annals of Glaciology, 2021 During the 2018/19 Antarctic field season, the British Antarctic Survey (BAS) Basal conditions on Rutford Ice Stream: BEd Access, Monitoring and Ice Sheet History’ (BEAMISH) project drilled three holes through the Rutford Ice Stream, West Antarctica.

Insights into ice stream dynamics through modelling their response to tidal forcing [PDF]
The Cryosphere, 2014 The tidal forcing of ice streams at their ocean boundary can serve as a natural experiment to gain an insight into their dynamics and constrain the basal sliding law.

Ice Streams of the Laurentide Ice Sheet [PDF]
Géographie physique et Quaternaire, 2006 Ice streams had a major influence on the configuration and the stability of the Laurentide Ice Sheet. Their identification is crucial for an understanding of ice sheet behaviour and their importance is reflected by the recent increase in paleo-ice stream research.

Advanced Functional Materials, EarlyView.Herein, an RBC membrane‐derived nanoparticle (CMN‐ICG) is engineered to efficiently deliver a sonosensitizing agent, indocyanine green (ICG), for sonotherapy of hepatocellular carcinoma (HCC). CMN‐ICG exhibits excellent cytocompatibility, significantly enhances hepatocyte uptake, and produces excessive reactive oxygen species (ROS) upon ultrasound ...

Ice-sheet surging and ice-stream formation [PDF]
Annals of Glaciology, 1996 A simplified model of ice-sheet behaviour is described. It combines the assumptions of rapid ice flow, high viscous activation energy and realistic sediment-based sliding dynamics to form a non-linear diffusion-type equation which can display relaxation oscillations analogous to those of surging glaciers, and which may be relevant to large-scale surges
