Dependence of sea ice yield-curve shape on ice thickness [PDF]
Journal of Physical Oceanography, 2004 In this note, the authors discuss the contribution that frictional sliding of ice floes (or floe aggregates) past each other and pressure ridging make to the plastic yield curve of sea ice.

Theory of the sea ice thickness distribution [PDF]
Physical Review Letters, 2015 We use concepts from statistical physics to transform the original evolution equation for the sea ice thickness distribution $g(h)$ due to Thorndike et al., (1975) into a Fokker-Planck like conservation law. The steady solution is $g(h) = {\cal N}(q) h^q

Brief communication: Measuring and modelling the ice thickness of the Grigoriev ice cap (Kyrgyzstan) and comparison with global datasets [PDF]
The Cryosphere, 2023 An accurate ice thickness distribution is crucial for correct projections of the future state of an ice mass. However, measuring the ice thickness with an in situ system is time-consuming and not scalable.

Arctic ice cover, ice thickness and tipping points. [PDF]
Ambio, 2012 We summarize the latest results on the rapid changes that are occurring to Arctic sea ice thickness and extent, the reasons for them, and the methods being used to monitor the changing ice thickness. Arctic sea ice extent had been shrinking at a relatively modest rate of 3-4% per decade (annually averaged) but after 1996 this speeded up to 10% per ...

Research on the Improvement Method of OPGW Ground Uneven Icing Calculation Model under Micro-terrain
Zhongguo dianli, 2023 At present, there are many studies on the calculation model of equivalent ice thickness of overhead line under uniform ice cover, but there is a lack of research on OPGW ground ice covering with large cross-section and large unit length weight ...
