Arctic Ice Cover, Ice Thickness and Tipping Points [PDF]

open access: yesAmbio, 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 ...

Wave radiation by a horizontal circular cylinder submerged in deep water with ice-cover

open access: yesJournal of Ocean Engineering and Science, 2019
Using the multipoles method, we formulate the problems of water wave radiation (both heave and surge) by a submerged circular cylinder in water with an ice-cover, the ice-cover being modelled as an elastic plate of very small thickness.

Analyzing links between simulated Laptev Sea sea ice and atmospheric conditions over adjoining landmasses using causal-effect networks [PDF]

open access: yesThe Cryosphere, 2020
We investigate how sea ice interacts with the atmosphere over adjacent landmasses in the Laptev Sea region as a step towards a better understanding of the connection between sea ice and permafrost.

Arctic sea ice cover data from spaceborne synthetic aperture radar by deep learning [PDF]

open access: yesEarth System Science Data, 2021
Widely used sea ice concentration and sea ice cover in polar regions are derived mainly from spaceborne microwave radiometer and scatterometer data, and the typical spatial resolution of these products ranges from several to dozens of kilometers.

The Influence of Snow and Ice Albedo towards Improved Lake Ice Simulations

open access: yesHydrology, 2021
Lake ice models are a vital tool for studying the response of ice-covered lakes to changing climates throughout the world. The Canadian Lake Ice Model (CLIMo) is a one-dimensional freshwater ice cover model that simulates Arctic and sub-Arctic lake ice ...

The fate of lake ice in the North American Arctic [PDF]

open access: yesThe Cryosphere, 2011
Lakes comprise a large portion of the surface cover in northern North America, forming an important part of the cryosphere. The timing of lake ice phenological events (e.g.

Assessment of the impact of dam reservoirs on river ice cover – an example from the Carpathians (central Europe) [PDF]

open access: yesThe Cryosphere
This paper presents a method for determining the impact of dam reservoirs on the ice cover of rivers downstream of their locations based on a long measurement period (1950–2020) and synthetic-aperture radar (SAR) data.

Less winter cloud aids summer 2013 Arctic sea ice return from 2012 minimum

open access: yesEnvironmental Research Letters, 2014
In September 2012, Arctic sea ice cover reached a record minimum for the satellite era. The following winter the sea ice quickly returned, carrying through to the summer when ice extent was 48% greater than the same time in 2012.

Internal waves under an ice cover [PDF]

open access: yesDoklady 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 ...
