High Fraction of Glacial Meltwater Along Two Separate Isopycnals Observed in Summer 2020 Near and Off the Pine Island and Thwaites Ice Shelves, West Antarctica

Journal of Geophysical Research: Oceans, Volume 131, Issue 4, April 2026.
Abstract The spatial distribution and dynamics of glacial meltwater (MW) influence ocean circulation off and basal melt rate below Antarctic ice shelves. While previous studies described the MW distribution in Pine Island Bay off Pine Island Ice Shelf (PIIS), quantitative constraints on the spatial heterogeneity of the spread of MW associated with ...

Effect of topography on subglacial discharge and submarine melting during tidewater glacier retreat. [PDF]

, 2017
-We explored secular variations in subglacial discharge and submarine melting with an idealized model -Subglacial discharge increases as tidewater glaciers retreat along retrograde beds -Submarine melting depends on subglacial discharge and ...

Radioglaciological studies on Hurd Peninsula glaciers, Livingston Island, Antarctica [PDF]

, 2009
We present the results of several radio-echo sounding surveys carried out on Johnsons and Hurd Glaciers, Livingston Island, Antarctica, between the 1999/2000 and 2004/05 austral summer campaigns, which included both radar profiling and common-midpoint ...

Variability in ice motion at a land-terminating Greenlandic outlet glacier: the role of channelized and distributed drainage systems

Journal of Glaciology, 2016
We use a combination of field observations and hydrological modelling to examine the mechanisms through which variability in meltwater input affects ice motion at a land-terminating Greenlandic outlet glacier. We find a close agreement between horizontal

Insights into glacial processes from micromorphology of silt-sized sediment [PDF]

The Cryosphere
Silt-rich meltwater plume deposits (MPDs) analyzed from marine sediment cores have elucidated relationships that are clearly connected, yet difficult to constrain, between subglacial hydrology, ice-marginal landforms, and grounding-zone retreat patterns ...

Influence of subglacial drainage system evolution on glacier surface motion: Haut Glacier d'Arolla, Switzerland [PDF]

, 2002
The relationship between the evolution of subglacial drainage system morphology and spatial patterns of glacier surface velocity was investigated using dye tracing experiments and ground surveying throughout the 1995 melt season at Haut Glacier d'Arolla,

Crack wave resonances within the basal water layer

Annals of Glaciology, 2019
Hydraulic processes within and beneath glacial bodies exert a far-reaching control on ice flow through their influence on basal sliding. Within the subglacial system, rapid changes in these processes may excite resonances whose interpretation requires an

Englacial Pore Water Localizes Shear in Temperate Ice Stream Margins [PDF]

, 2019
The margins of fast‐moving ice streams are characterized by steep velocity gradients. Some of these gradients cannot be explained by a temperature‐dependent viscosity alone.
