Liquid Brine in Ice Shelves [PDF]
Journal of Glaciology, 1975 Holes drilled into thin areas of the Brunt Ice Shelf encounter a layer of liquid brine less than 1 m thick approximately at sea-level. Assuming the brine to be moving horizontally, analysis of its effects on thermal equilibrium gives an estimate of steady-state annual brine flow that is in good agreement with the value deduced from a percolation model.

Comparing calving laws at Greenland's three largest ice shelves [PDF]
The CryosphereThe retreat of Greenlandic glaciers through calving has major implications for the ice sheet's mass balance and future sea-level rise contributions. Despite its importance, the implementation of calving in ice sheet models remains contested, with several

A phase field model for fractures in ice shelves [PDF]
, 2023 Ice shelves are large floating ice masses, that are formed when glaciers are becoming afloat at the margin of ice sheets. One dominating mass loss mechanism of ice shelves is calving, describing the detachment of icebergs at the front.

Evaluation of four calving laws for Antarctic ice shelves [PDF]
The Cryosphere, 2023 Many floating ice shelves in Antarctica buttress the ice streams feeding them, thereby reducing the discharge of icebergs into the ocean. The rate at which ice shelves calve icebergs and how fast they flow determine whether they advance, retreat, or ...

Explicit representation and parametrised impacts of under ice shelf seas in the z∗ coordinate ocean model NEMO 3.6 [PDF]
Geoscientific Model Development, 2017 Ice-shelf–ocean interactions are a major source of freshwater on the Antarctic continental shelf and have a strong impact on ocean properties, ocean circulation and sea ice.

Automatic Extraction of the Calving Front of Pine Island Glacier Based on Neural Network
Remote Sensing, 2023 Calving front location plays a crucial role in studying ice–ocean interaction, mapping glacier area change, and constraining ice dynamic models. However, relying solely on visual interpretation to extract annual changes in the calving front of ice ...

Speed-up, slowdown, and redirection of ice flow on neighbouring ice streams in the Pope, Smith, and Kohler region of West Antarctica [PDF]
The CryosphereThe ice streams feeding the Dotson and Crosson ice shelves are some of the fastest changing in West Antarctica. We use satellite observations to measure the change in ice speed and flow direction on eight ice streams in the Pope, Smith, and Kohler region

How the ocean melts Antarctic ice
Communications Earth & Environment, 2022 The floating ice shelves around Antarctica are key to buttressing land-based ice. Observations, simulations and analyses from around Antarctica now identify mechanisms that lead to basal melting of these vulnerable shelves.
