Numerical model of the ice cover evolution in Arctic Seas for the operational forecasting

open access: yesЛëд и снег, 2015
The dynamic-thermodynamic model of the ice cover evolution is used for operational 5‑day ice forecasts in the Russian Arctic seas and to obtain some statistical estimates of the ice cover state. The model is a numerical realization of the heat budget and

Sea-ice cover timing in the Pacific Arctic: The present and projections to mid-century by selected CMIP5 models

open access: yesDeep-sea research. Part II, Topical studies in oceanography, 2017
With the sea-ice cover in the Arctic fast declining, changes to the timing of sea-ice break-up and freeze-up is an urgent economic, social, and scientific concern.

A Bayesian Logistic Regression for Probabilistic Forecasts of the Minimum September Arctic Sea Ice Cover

open access: yesEarth and Space Science, 2020
This study introduces a Bayesian logistic regression framework that is capable of providing skillful probabilistic forecasts of Arctic sea ice cover, along with quantifying the attendant uncertainties.

Sea ice dynamics in the Bransfield Strait, Antarctic Peninsula, during the past 240 years: a multi-proxy intercomparison study [PDF]

open access: yesClimate of the Past, 2020
In the last decades, changing climate conditions have had a severe impact on sea ice at the western Antarctic Peninsula (WAP), an area rapidly transforming under global warming.

Methane oxidation at the water‐ice interface of an ice‐covered lake [PDF]

open access: yesLimnology and Oceanography, 2016
AbstractLakes are important components of the global methane (CH4) cycle. In seasonally ice‐covered lakes, CH4 transported by ebullition (bubbling) from anoxic sediments gets trapped at the water‐ice interface. If not oxidized by methane‐oxidizing bacteria (MOB), this can potentially lead to high episodic CH4 emissions at ice‐melt.

Use of Landsat Satellite Images in the Assessment of the Variability in Ice Cover on Polish Lakes

open access: yesRemote Sensing, 2023
Despite several decades of observations of ice cover in Polish lakes, researchers have not broadly applied satellite images to date. This paper presents a temporal and spatial analysis of the variability in the occurrence of ice cover on lakes in the ...

Interannual variability in phytoplankton biomass and species composition in northern Marguerite Bay (West Antarctic Peninsula) is governed by both winter sea ice cover and summer stratification

open access: yes, 2017
The rapid warming of the West Antarctic Peninsula region has led to reduced sea ice cover and enhanced glacial melt water input. This has potential implications for marine ecosystems, notably phytoplankton growth, biomass, and composition. Fifteen years (

Method for Solving the Problem of Load Movement over the Ice Cover of a Reservoir along a Complex Trajectory

open access: yesAdvanced Engineering Research, 2023
Introduction. The development of the polar regions of the World Ocean contributed to an increased interest in studying wave processes in water bodies with ice cover caused by the action of a mobile load. In most papers of domestic and foreign scientists,
