Climate change impacts on the Alpine ecosystem: an overview with focus on the soil

Journal of Forest Science, 2015
The Alpine ecosystem is very sensitive to climatic changes, which have an influence on glaciers, snow, vegetation and soils. The aim of this review is to illustrate the effects of global change on the Alpine soil ecosystem, which is an optimal marker to ...

Dynamic Boundaries of Antarctic Active Subglacial Lakes Reveal Underestimated Water Volume Change and Overestimated Lakebed Active Area

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract This study revisited 158 documented active subglacial lakes across Antarctica, applying a height‐change anomaly delineation algorithm to CryoSat‐2 and ICESat‐2 satellite altimetry data to assemble a 14.75‐year (2010.5–2025.25) time series of active subglacial lake dynamics.

Hidden Bioavailable Dissolved Organic Matter in the Deep Northwestern Pacific Ocean

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract The deep ocean is widely viewed as a stable reservoir of dissolved organic carbon (DOC) that is highly resistant to microbial degradation. However, this paradigm may be oversimplified. In a cross‐latitude survey conducted in the northwestern Pacific Ocean (155°E, 28.5°N–41.5°N), bulk DOC concentrations were found to be relatively constant ...

Wind‐Driven Coastal Polynya Variability Drives Decadal Ice‐Shelf Melt Variability in the Amundsen Sea

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract The ice shelves in the Amundsen Sea are being melted rapidly by warm Circumpolar Deep Water (CDW), causing sea‐level rise. Ice‐shelf melt variability is controlled by the speed of a shelf‐break undercurrent which transports CDW onto the continental shelf. We study decadal variability of the undercurrent and ice‐shelf melting using new regional

The Evolving Paleobathymetry of the Circum‐Antarctic Southern Ocean Since 34 Ma: A Key to Understanding Past Cryosphere‐Ocean Developments

Geochemistry Geophysics Geosystems, 2020
The Southern Ocean is a key player in the climate, ocean, and atmospheric system. As the only direct connection between all three major oceans since the opening of the Southern Ocean gateways, the development of the Southern Ocean and its relationship ...

Flocculated Silt, Not Clay, Dominates River Suspended Sediment Load

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract River mud builds fertile floodplains, combats land loss due to sea level rise, and buries vast amounts of organic carbon. These processes rely on mud settling velocity, which is set by the grain size, mineralogy, and flocculation state of mud. Here we determined these factors using a suspended sediment data compilation from lowland rivers and ...

Microbial ecology of the cryosphere (glacial and permafrost habitats): current knowledge

Applied Microbiology and Biotechnology, 2019
Microorganisms in cold ecosystems play a key ecological role in their natural habitats. Since these ecosystems are especially sensitive to climate changes, as indicated by the worldwide retreat of glaciers and ice sheets as well as permafrost thawing, an

Thinking Outside the Rocks: Subsurface Water Storage, Topography, and Land Cover Are Key Modulators of Large‐Scale Riverine Dissolved Silicon Dynamics

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Riverine dissolved silicon (DSi) dynamics reflect integrated geologic, hydrologic, climatic, and ecological controls. We compiled annual DSi data for 337 rivers across four continents and trained interpretable machine‐learning models to predict concentrations and yields from 28 watershed variables.

The Zonal Wave‐3 Mode Impacts Antarctic Dense Water Formation

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract At the Antarctic margins, dense water masses form as sea ice develops, driving the Antarctic branch of the global meridional overturning circulation. Previous studies found that large‐scale climate modes such as the Southern Annular Mode and El Niño Southern do not fully account for the interannual variability of dense water formation.

GROWTH OF GAS HYDRATES IN THE WATER/OIL EMULSIONS ACCORDING TO METHOD DIFFERENTIAL THERMAL ANALYSIS

Известия высших учебных заведений: Нефть и газ, 2014
Some experimental aspects of the DTA method for determination of a degree of hydrate formation of water/oil emulsion samples are considered. The growth of hydrate in micron-size droplets of water depending on a number of cycles of freezing – thawing is ...
