Arctic sea ice mass balance in a new coupled ice–ocean model using a brittle rheology framework [PDF]
The Cryosphere, 2023 Sea ice is a key component of the Earth's climate system as it modulates the energy exchanges and associated feedback processes at the air–sea interface in polar regions.

Short-Term Rheology of Polycrystalline Ice [PDF]
Journal of Glaciology, 1978 Abstract Deformation characteristics of polycrystalline ice and their dependence on time, temperature, and stress have been analysed on the basis of a phenomenological relation which describes creep in terms of initial elastic, delayed elastic, and permanent strain.

Improving the spatial distribution of modeled Arctic sea ice thickness [PDF]
, 2005 The spatial distribution of ice thickness/draft in the Arctic Ocean is examined using a sea ice model. A comparison of model predictions with submarine observations of sea ice draft made during cruises between 1987 and 1997 reveals that the model has the

Modelling the influence of marine ice on the dynamics of an idealised ice shelf
Journal of Glaciology, 2023 Understanding the dynamic behaviour of ice shelves, specifically the controls on their ability to buttress the flow of ice into the ocean, is critical for predicting future ice-sheet contributions to sea level rise.

Additive Manufacturing of High‐Performance Polymers for Extreme Environments [PDF]
Advanced scienceAdditive manufacturing of high‐performance polymers for extreme environments is critically reviewed through an integrated chemistry‐processing‐structure‐property‐qualification framework. The review compares fused filament fabrication, selective laser sintering, and direct ink writing, linking rheology and thermal history to crystallization, defect ...

On the influence of model physics on simulations of Arctic and Antarctic sea ice [PDF]
The Cryosphere, 2011 Two hindcast (1983–2007) simulations are performed with the global, ocean-sea ice models NEMO-LIM2 and NEMO-LIM3 driven by atmospheric reanalyses and climatologies.

The anomalous pressure drop behaviour of ice slurries flowing through constrictions [PDF]
, 2008 The effective ‘viscosity’ for ice slurry containing more than say 30 to 40% ice fraction is many orders of magnitude higher than that for water. However, this work suggests that such slurries, when flowing through constrictions, can incur lower pressure ...

Impact of Variable Atmospheric and Oceanic Form Drag on Simulations of Arctic Sea Ice [PDF]
, 2014 Over Arctic sea ice, pressure ridges and floe and melt pond edges all introduce discrete obstructions to the flow of air or water past the ice and are a source of form drag.

Implementation of a Maxwell Elasto-Brittle Rheology in a Sea Ice Model Coupled to an Ocean [PDF]
, 2022 The viscous-plastic (VP) rheology and the Maxwell elasto-brittle (MEB) rheology were compared in a common framework. To this end, the Massachusetts Institute of Technology general circulation model (MITgcm) was complemented by the MEB rheology for sea ...

Cyclic strengthening of lake ice
Journal of Glaciology, 2021 Further to systematic experiments on the flexural strength of laboratory-grown, fresh water ice loaded cyclically, this paper describes results from new experiments of the same kind on lake ice harvested in Svalbard. The experiments were conducted at −12
