Compressional and EM Wave Velocity Anisotropy in a Temperate Glacier Due to Basal Crevasses, and Implications for Water Content Estimation [PDF]

, 2013
We have conducted a series of experiments designed to investigate elastic and electromagnetic (EM) velocity anisotropy associated with a preferentially aligned fracture system on a temperate valley glacier in south-central Alaska, USA.

Temperature dynamics in crevasse-drainage systems of Antarctic glaciers [PDF]

Journal of the Bulgarian Geographical Society
During the 33rd Bulgarian Antarctic Expedition, field studies were conducted to examine the internal microclimate of crevasse-drainage systems of the three glaciers: Balkan Ice Field, Johnsons and Contell Glaciers.

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 ...

Rift propagation signals the last act of the Thwaites Eastern Ice Shelf despite low basal melt rates

Journal of Glaciology
Rift propagation, rather than basal melt, drives the destabilization and disintegration of the Thwaites Eastern Ice Shelf. Since 2016, rifts have episodically advanced throughout the central ice-shelf area, with rapid propagation events occurring during ...

Theoretical stability of ice shelf basal crevasses with a vertical temperature profile

Journal of Glaciology
Basal crevasses threaten the stability of ice shelves through the potential to form rifts and calve icebergs. Furthermore, it is important to determine the dependence of crevasse stability on temperature due to large vertical temperature variations on ...
