Structural Evolution During Cyclic Glacier Surges: 1. Structural Glaciology of Trapridge Glacier, Yukon, Canada [PDF]
Journal of Geophysical Research F: Earth Surface, 2019 Interpreting the relationships among the internal processes of glaciers and their mesoscale structural products has been a long‐standing challenge for glaciologists. Trapridge Glacier is a small polythermal surge‐type valley glacier that has been studied for 40 years. It offers an opportunity to investigate the structural evolution of a glacier through

The structural glaciology of southwest Antarctic Peninsula Ice Shelves (ca. 2010)
Journal of Maps, 2013 The Antarctic Peninsula has recently seen a rapid breakup of its peripheral ice shelves, attributed to atmospheric and oceanic warming in the region. Previous work has illustrated that the final breakup mechanisms are often controlled by the structural glaciology of the ice shelf, and thus understanding the structure of the remaining ‘stable’ ice ...

The Structural Glaciology of a Temperate Valley Glacier: Haut Glacier d'Arolla, Valais, Switzerland
Arctic, Antarctic, and Alpine Research, 2005 Abstract This paper describes the structural glaciology of Haut Glacier d'Arolla, a small valley glacier fed by two distinct accumulation basins in the Swiss Alps. A considerable body of field data is presented alongside observations from ground and aerial photographs.

Structural evolution during a surge in the Paulabreen glacier system, Svalbard
Journal of Glaciology, 2023 We assess the evolution of glaciological structures during the 2003–05 surge in the Paulabreen glacier system, Svalbard. Glaciological structures on the glacier surface were mapped using aerial photographs captured in the early stages of the surge (2003)

Microstructures in a shear margin: Jarvis Glacier, Alaska
Journal of Glaciology, 2021 Microstructures, including crystallographic fabric, within the margin of streaming ice can exert strong control on flow dynamics. To characterize a natural setting, we retrieved three cores, two of which reached bed, from the flank of Jarvis Glacier ...

Thermal refraction: implications for subglacial heat flux
Journal of Glaciology, 2021 In this study, we explore small-scale (~1 to 20 km) thermal-refractive effects on basal geothermal heat flux (BGHF) at subglacial boundaries resulting from lateral thermal conductivity contrasts associated with subglacial topography and geologic contacts.

Structural glaciology of Austre Brøggerbreen, northwest Svalbard [PDF]
Journal of Maps, 2015 Structural glaciological maps can be used to study the structural evolution and past dynamics of glaciers. The map described here documents the glacier-wide structural characteristics of Austre Brøggerbreen, a c. 12 km2 predominantly cold-based valley glacier in northwest Svalbard.

Journal of Glaciology, 2022 Since the mid-20th century, ice shelves around the Antarctic Peninsula have declined in extent and thickness, and some have shown signs of structural instability.

Journal of Glaciology, 2022 Polycrystalline ice is known to exhibit macroscopic anisotropy in relative permittivity (ɛ) depending on the crystal orientation fabric (COF). Using a new system designed to measure the tensorial components of ɛ, we investigated the dielectric anisotropy

A stratigraphy-based method for reconstructing ice core orientation
Annals of Glaciology, 2021 Ever since the first deep ice cores were drilled, it has been a challenge to determine their original, in-situ orientation. In general, the orientation of an ice core is lost as the drill is free to rotate during transport to the surface. For shallow ice
