Differences in behavior and distribution of permafrost-related lakes in Central Yakutia and their response to climatic drivers [PDF]
The Central Yakutian permafrost landscape is rapidly being modified by land use and global warming, but small-scale thermokarst process variability and hydrological conditions are poorly understood.

Effects of Hillslope Thermokarst in Northern Alaska [PDF]
Permafrost thawing is increasing in the Arctic and sub‐Arctic [Osterkamp and Romanovsky, 1996; Osterkamp, 2007] in response to climate warming [Hassol, 2004]. One consequence of thawing permafrost is the development of thermokarst (physical depression of ground surface) because of reduced support of overlying soil [Jorgenson et al., 2006].

This study examines the distribution and morphology of lakes under the Laurentide Ice Sheet (LIS) to investigate relationships with ice flow velocity, bedrock and basal thermal regime. Palaeo‐ice streams and lobes were important components of the LIS, and properties of lakes in those regions are quantified at high resolution.

Holocene thermokarst and pingo development in the Kolyma Lowland (NE Siberia) [PDF]
Ground ice and sedimentary records of a pingo exposure reveal insights into Holocene permafrost, landscape and climate dynamics. Early to mid‐Holocene thermokarst lake deposits contain rich floral and faunal paleoassemblages, which indicate lake ...

Projected radiative forcing from a thermokarst bog in Boreal Alaska depends on methane emission transport pathway dominance, with aerenchyma‐ and diffusion‐dominant causing net warming and ebullition‐dominant causing net cooling. Predicted methane shows a transient response as air temperature increases in future projections causing soil drying and ...

Remote Sensing Risk Assessment of Valdez Glacier Lake [PDF]
Can remote sensing techniques be used to determine the probability of an outburst from the Valdez Glacier Lake, and to detect downstream areas affected by a possible glacier lake outburst ...

Abstract Glacier‐fed streams (GFSs) make ideal systems for studying climate‐related changes. Some of the best‐studied GFSs are found in the McMurdo Dry Valleys (MDVs) of Antarctica, one of the Earth's coldest and driest deserts. Despite their harsh and isolated nature, MDV GFSs represent an oasis of life in a landscape visually devoid of it, with ...

Issues Related to Incorporating Northern Peatlands into Global Climate Models [PDF]
Northern peatlands cover ~3–4 million km2 (~10% of the land north of 45°N) and contain ~200–400 Pg carbon (~10–20% of total global soil carbon), almost entirely as peat (organic soil).

Landsat-Based Trend Analysis of Lake Dynamics across Northern Permafrost Regions [PDF]
Lakes are a ubiquitous landscape feature in northern permafrost regions. They have a strong impact on carbon, energy and water fluxes and can be quite responsive to climate change.
