Taaliku

Taaliku (plural: taalikud) refers to a zone of unfrozen ground that lies within a permafrost area. It is not frozen year-round, even in regions characterized by continuous or discontinuous permafrost. Taalikud often form under or near water bodies such as rivers, lakes, or the sea, where the water's relatively warm temperature prevents the ground from freezing solid. The presence of a taalik can have significant hydrological and ecological implications in permafrost regions, influencing groundwater flow, vegetation distribution, and the stability of the ground. Specifically, a taalik can provide pathways for subsurface water movement, leading to the discharge of groundwater into surface water bodies. These areas can also act as important habitats for certain plant and animal species. Taalik formation and dynamics are closely linked to climate change, as warming temperatures can lead to the expansion or creation of taalik zones, potentially destabilizing permafrost landscapes and releasing stored organic matter.
