Thousands of industrial sites were found to be correlated with contaminated sites in the Arctic. Between 13,000 and 20,000 contaminated sites are likely to exist in the permafrost region, 26% of which will be affected by permafrost thaw before 2100.

Ecological and geochemical characteristics of the snow cover in the Yakutsk city (Central Siberia)
For the first time, the geochemistry of snow cover on the territory of the city of Yakutsk, the largest city located in the permafrost zone, is considered on the basis of recent methods of analysis. To study the chemical composition of the snow cover and

Heavy and Light Mineral Association of Late Quaternary Permafrost Deposits in Northeastern Siberia
We studied heavy and light mineral associations from two grain-size fractions (63–125 μm, 125–250 µm) from 18 permafrost sites in the northern Siberian Arctic in order to differentiate local versus regional source areas of permafrost aggradation on the ...

Last October, when Susan Hubbard and her team pulled sleds full of sensitive sensors across the snow near the northernmost point in Alaska, temperatures hovered in the single digits and low teens (e.g., 8–15 °F). Foremost in the researchers’ minds, aside from collecting data on the frozen ground beneath their feet, were two things: keep an eye out for ...

Measurement of Excess Pore-Water Pressure in Frozen Soil at Subfreezing Temperatures Close to 0°C
Response of pore-water pressure has crucial effect on the engineering geological performance of permafrost ground. However, there is a dearth of literature on the measurement of pore-water pressure in frozen soils due to challenges with regard to ...

Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Permafrost, or perennially frozen ground, occurs widely throughout the northern half of Canada. Experience has shown that special design and construction techniques are required for building on permafrost in order to avoid disturbing the delicate thermal balance that preserves the frozen ground.

Relationships between greenhouse gas production and landscape position during short-term permafrost thaw under anaerobic conditions in the Lena Delta [PDF]
Soils in the permafrost region have acted as carbon sinks for thousands of years. As a result of global warming, permafrost soils are thawing and will potentially release greenhouse gases (GHGs) such as methane (CH4) and carbon dioxide (CO2).
