Does Palsa Thaw in Northern Finland Contribute to Remobilisation of Metals Accumulated in Peat Into Surface Waters?

Land Degradation &Development, EarlyView.
ABSTRACT Permafrost is rapidly degrading in the sporadic zone, including palsa mires in Scandinavia. Peatlands in the area have likely accumulated heavy metals from atmospheric deposition of industrial contaminants in the wider region. As the palsa mire chemical composition is not well known, and in other permafrost regions the permafrost thaw may ...

Centring care as part of Indigenous environmental stewardship: Collective learning through cultural plants

People and Nature, EarlyView.
Abstract Stewardship is broadly defined as ‘universal responsibility of humanity to care for the planet, to ensure that it can continue to provide the essential natural resources for life’. Stewardship practices shape ecosystems, create diverse biocultural landscapes, and can enhance the productivity, availability and health of plants used by ...

Recession of glaciers in the Suntar-Khayata Mountains and methodological consideration of its assessment

Лëд и снег, 2015
This study of glacial-cryogenic complexes of Suntar-Khayata Range is a logical continuation of the research started by M.M. Koreysha in 1957–1959. The studied key site is situated in the upstream of the Burgaly River on the northern slope of Mus-Khaya ...

Numerical modeling of two-dimensional temperature dynamics across ice-wedge polygons [PDF]

, 2017
Thesis (M.S.) University of Alaska Fairbanks, 2017The ice wedges on the North Slope of Alaska have been forming for many millennia, when the ground cracked and the cracks were filled with snowmelt water.

Permafrost Distribution in the Canadian Rockies: Key Variables Influencing Patch‐Scale Variability

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT The spatial distribution of permafrost in mountainous regions is influenced by various factors such as topography, climate, vegetation, and substrate. Despite the existence of comprehensive permafrost maps at national and global levels, they fail to accurately represent the patch‐scale (e.g., < 25 m) permafrost distribution in characteristic ...

Brief communication: Testing a portable Bullard-type temperature lance confirms highly spatially heterogeneous sediment temperatures under shallow bodies of water in the Arctic [PDF]

The Cryosphere
The thermal regime in the sediment column below shallow bodies of water in Arctic permafrost controls benthic habitats and permafrost stability. We present a robust, portable device that measures detailed temperature–depth profiles of the near-surface ...

Experimental Investigation of Moisture Movement During Freeze–Thaw Cycles and Its Effect on Physical Rock Weathering in Low‐Porosity Alpine Limestone

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT The progressive weakening of alpine rockwalls through subcritical cracking, driven by repeated low‐magnitude stress processes, plays a key role in alpine rock weathering. Laboratory studies using acoustic emission (AE) monitoring have shown that thermal stresses from freeze–thaw cycling induce crack propagation, with recent work highlighting ...

Policy implications of warming permafrost [PDF]

Permafrost is perennially frozen ground occurring in about 24% of the exposed land surface in the Northern Hemisphere. The distribution of permafrost is controlled by air temperature and, to a lesser extent, by snow depth, vegetation, orientation to ...
