Project

Distribution, Thickness and Evolution of Permafrost in Central Europe in Late Quaternary (GA21-23196S)

permafrost changes in non-alpine Central Europe. We intend to answer still-discussed and largely unresolved problems of what were the glacier–permafrost interactions around the southern limit of the Scandinavian ice sheet, how ...

Dynamics of the periglacial environment in the Antarctic Peninsula region under ongoing climate change (GM22-28659M)

The active layer and permafrost are the building elements of the periglacial environment in polar regions. Their parameters like temperature, moisture, or active layer and permafrost temperature belongs to principal questions of An...

Determining the influence of frost heave and thaw settlement on the thermal regime of frozen ground and its implementation in freeze-thaw models (GA25-18272S)

Vertical ground deformations due to frost heave and thaw settlement are important features in regions of permafrost and seasonally frozen ground, often causing physical modelling experiments simulating permafrost and seasonally froz...

Microbiomes of Selected Extreme Biotopes – Their Phylogenetic Diversity and Functional Potential (LTAUSA19028)

The objective of the proposed project is to characterize microbial populations in extreme biotopes – chronosequence of permafrost (permafrost of differing age) from central Alaska and soils from salt marshes and moffettes of the Soo...

CRYOVULCAN - Vulnerability of carbon in Cryosols – substrate-microorganisms-aggregate interactions (GC20-21259J)

Thawing of the permafrost may result in two contrasting scenarios of the active layer: wetter or drier soil. The main objective of the project is to comparatively investigate OM decomposition and stabilization under these two scenarios. Our ...

Multiphase flow, transport, and structural changes related to water freezing and thawing in the subsurface (GA21-09093S)

The on-going climate changes observed during last decades cause release of methane and other gases from thawing permafrost in arctic regions. Understanding the fundamental processes of freezing or thawing of a porous medium containing fluid,...

Long-term Carbon Storage in Cryoturbeated Arctic Soils (7E10073)

The total organic carbon pool of soils (SOC) of the circum-arctic permafrost zone has been estimated to contain ~400 Gt C in the upper 1m and as much as 747 Gt C in the upper 3m, excluding peatlands and carbon in deep loess sediment reservoi...
