Use of Ice Covers for Transportation

Canadian Geotechnical Journal, 1971
Observations are reported on the failure and use of freshwater ice covers for vehicular traffic. The study showed that good quality ice covers can support loads of up to P = 250 h2, where P is the total load in pounds and h is the thickness of the ice in inches. Failures were reported, however, for loadings as low as P = 50 h2. Factors contributing to

Including debris cover effects in a distributed model of glacier ablation [PDF]

, 2012
Distributed glacier melt models generally assume that the glacier surface consists of bare exposed ice and snow. In reality, many glaciers are wholly or partially covered in layers of debris that tend to suppress ablation rates.

Motion of a submerged body in a near-surface water environment

International Journal of Naval Architecture and Ocean Engineering, 2022
This study considered the motion of a submerged body near the free surface of a liquid and a liquid covered with ice cover, both theoretically and experimentally. Mathematically, the body was modelled using the source–sink system.

Giant ice rings in southern Baikal: multi-satellite data help to study ice cover dynamics and eddies under ice [PDF]

The Cryosphere, 2021
Ice cover on lakes is subject to atmospheric forcing from above and the influence of water dynamics and heat flux from below. One characteristic example of these influences in some large lakes, such as Lake Baikal in Russia, are the giant ice rings and ...

Internal waves under an ice cover [PDF]

Doklady Earth Sciences, 2008
A theoretical model for propagation of internal waves under an ice cover is developed. The sea water is considered to be inviscid, non-rotating, and incompressible and the Brunt–Väisälä frequency is supposed to be constant. The ice is considered of uniform thickness, with constant values of Young's modulus, Poisson's ratio, density and compressive ...

Investigating future changes in the volume budget of the Arctic sea ice in a coupled climate model [PDF]

The Cryosphere, 2018
We present a method for analysing changes in the modelled volume budget of the Arctic sea ice as the ice declines during the 21st century. We apply the method to the CMIP5 global coupled model HadGEM2-ES to evaluate how the budget components evolve ...

Geographic muting of changes in the Arctic sea ice cover [PDF]

, 2010
The seasonal cycle in Arctic sea ice extent is asymmetric. Its amplitude has grown in recent decades as the ice has retreated more rapidly in summer than in winter.

The ice regime of Lake Raduńskie Górne (Kashubian Lakeland, northern Poland)

Limnological Review, 2017
The paper presents assessment results of the ice dynamics on Lake Raduńskie Górne (Upper Radunia Lake) based on long-term observations of the course of ice phenomena.

Polar winter climate change: strong local effects from sea ice loss, widespread consequences from warming seas [PDF]

Atmospheric Chemistry and Physics
Decreasing sea ice cover and warming sea surface temperatures (SSTs) impact the climate at both poles in uncertain ways. We aim to reduce the uncertainty by comparing output of 41-year-long simulations from four atmospheric general circulation models ...

Expedition 302 geophysics: integrating past data with new results [PDF]

, 2006
In preparation for IODP Expedition 302, Arctic Coring Expedition (ACEX), a site survey database comprising geophysical and geological data from the Lomonosov Ridge was compiled.
