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 ...

Influence of winter sea-ice motion on summer ice cover in the Arctic

open access: yesPolar Research, 2013
Summer sea-ice cover in the Arctic varies largely from year to year owing to several factors. This study examines one such factor, the relationship between interannual difference in winter ice motion and ice area in the following summer.

ANALYSIS OF INTERANNUAL AND SEASONAL VARIABILITY OF ICE COVER IN ANIVA BAY AND LA PEROUSE STRAIT ACCORDING TO EARTH REMOTE SENSING DATA

open access: yesInterCarto. InterGIS, 2017
Based on the data of satellite observations of the ice cover with the use of geoinformation technologies, an analysis of the interannual and seasonal variability of ice cover in Aniva Bay and La Perouse Strait has been made.

The Arctic’s rapidly shrinking sea ice cover: a research synthesis

open access: yesClimatic Change, 2012
The sequence of extreme September sea ice extent minima over the past decade suggests acceleration in the response of the Arctic sea ice cover to external forcing, hastening the ongoing transition towards a seasonally open Arctic Ocean.

Nonlinear winter atmospheric circulation response to Arctic sea ice concentration anomalies for different periods during 1966–2012

open access: yesEnvironmental Research Letters, 2015
The early 21st century was marked by several severe winters over Central Eurasia linked to a blocking anti-cyclone centered south of the Barents Sea. Severe winters in Central Eurasia were frequent in the 1960s when Arctic sea ice cover was anomalously ...

Salinity impact on water flow and lake ice in Lake Vostok, Antarctica [PDF]

open access: yes, 2003
Lake Vostok, isolated from direct exchange with the atmosphere for million years, provides a unique and so far inaccessible habitat. By using a numerical model, and recent lake geometry information, the lake circulation was investigated for different ...

Use of Ice Covers for Transportation

open access: yesCanadian 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
