Permafrost trapped natural gas in Svalbard, Norway

open access: yesFrontiers in Earth Science, 2023
Permafrost is widespread in the High Arctic, including the Norwegian archipelago of Svalbard. The uppermost permafrost intervals have been well studied, but the processes at its base and the impacts of the underlying geology have been largely overlooked.

Frozen Soil Hydrological Processes and Their Effects: A Review and Synthesis

open access: yesReviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract Frozen soils, including seasonally frozen ground and permafrost, are rapidly changing under a warming climate, with cascading effects on water, energy, and carbon cycles. We synthesize recent advances in the physics, observation, and modeling of frozen‐soil hydrology, emphasizing freeze–thaw dynamics, infiltration regimes and preferential flow,

Ku-, X- and C-Band Microwave Backscatter Indices from Saline Snow Covers on Arctic First-Year Sea Ice

open access: yesRemote Sensing, 2017
In this study, we inter-compared observed Ku-, X- and C-band microwave backscatter from saline 14 cm, 8 cm, and 4 cm snow covers on smooth first-year sea ice.

Glacier‐Atmosphere Interactions and Feedbacks in High‐Mountain Regions ‐ A Review

open access: yesReviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract Mountain glaciers are among the natural systems most vulnerable to climate change. However, their interactions with the atmosphere are complex and not fully understood. These interactions can trigger rapid adjustments and climate feedbacks that either amplify or attenuate atmospheric signals, influencing both glacier response and large‐scale ...

The effect of “annealing” on the specific crushing energy of the layered frozen ice.

open access: yesЛëд и снег
The paper demonstrates realization of an experimental method of shock destruction of ice in order to study its specific energy of destruction and strength under various annealing conditions. Ice was prepared by layer-by layer freezing of distilled water.

REGULARITIES OF GEOCHEMICAL COMPOSITION FORMATION OFUNDERGROUND ICE AND DEPOSITS ON THE NORTH OF THE GYDAN PENINSULA

open access: yesИзвестия высших учебных заведений: Нефть и газ, 2018
The study of underground ice and frozen soils on the north of the Gydan Peninsula was made in 2016. The article is devoted to the results of the study. The granulometric and geochemical composition of the frozen deposits, the hydrochemical composition of

Climate change, melting cryosphere and frozen pathogens: Should we worry…?

open access: yesEnvironmental Sustainability, 2021
Permanently frozen environments (glaciers, permafrost) are considered as natural reservoirs of huge amounts of microorganisms, mostly dormant, including human pathogens.

Potential Impacts of Climate Interventions on Marine Ecosystems

open access: yesReviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract Rising global temperatures pose significant risks to marine ecosystems, biodiversity, and fisheries. Recent comprehensive assessments suggest that large‐scale mitigation efforts to limit warming are falling short, and all feasible future climate projections, including those that represent optimistic emissions reductions, exceed the Paris ...

GIS and field data-based modelling of snow water equivalent in shrub tundra

open access: yesFennia: International Journal of Geography, 2015
An approach for snow water equivalent (SWE) modelling in tundra environments has been developed for the test area on the Yamal peninsula. Detailed mapping of snow cover is very important for tundra areas under continuous permafrost conditions, because ...

INFLUENCE OF THE TIME STORAGE OF ICE POWDER ON KINETICS OF FORMATION AND GROWTH OF FREON-12 GAS HYDRATE

open access: yesИзвестия высших учебных заведений: Нефть и газ, 2018
The article explores the influence a storage time on the samples of pure ice powder and mod-ified ice powder with polyvinylpyrrolidone on process formation and growth of the gas hydrate by used P-V-T measurements.
