Fracture of Antarctic shelf ice
Journal of Geophysical Research: Solid Earth, 2002We have investigated the fracture of Antarctic shelf ice core using two fracture mechanics test methods: the chevron‐notched short‐rod specimen loaded in tension and the chevron‐notched round‐bar specimen loaded in three‐point bending. These tests have been used to measure the fracture initiation toughness, Kinit, at which crack growth starts, on ...

INTRODUCTION Of all Antarctic glacial features, none is as characteristic or as distinctive and none has excited as much interest and as much speculation from explorers, as the areas of shelf ice which occupy protected or partly protected areas about the continent. The best known and largest of these is the Ross Shelf Ice, which extends northward from

Science, 2001
GEOLOGY Several small ice shelves around the Antarctic Peninsula retreated during the late 20th century due to regional climate warming. Did similar retreats occur through natural climate variability during the past 10,000 years. Pudsey and Evans have now addressed this question by studying the history of the Prince Gustav Channel ice shelf.

The spreading of an unconfined ice shelf in two horizontal directions involves the variation of the two horizontal velocity components and the thickness in both directions. Exploiting the slow variation of physical quantities in both horizontal directions compared to vertical variation allows simple solution of the vertical momentum balance and the ...

Modelling ice-shelf/ocean interaction
2023The effect of climate change on the mass balance of ice shelves and bottom water formation is investigated using a terrain-following three-dimensional numerical ocean model. The Regional Ocean Modeling System was modified to simulate the thermodynamic processes beneath ice shelves, including direct basal processes and frazil ice dynamics.

Movement of the Amery Ice Shelf
Polar Record, 1967The Lambert Glacier system, one of the largest in Antarctica, drains from Princess Elizabeth Land into Prydz Bay, terminating in the Amery Ice Shelf, in about long 70° to 75° E.
