Effects of Permafrost Degradation on Ecosystems

Acta Ecologica Sinica, 2010
Abstract Permafrost, covering approximately 25% of the land area in the Northern Hemisphere, is one of the key components of terrestrial ecosystem in cold regions. As a product of cold climate, permafrost is extremely sensitive to climate change. Climate warming over past decades has caused degradation in permafrost widely and quickly.

Highway Embankment on Degrading Permafrost

Cold Regions Engineering 2009, 2009
The highway embankment is about 800 km (500 miles) north of Winnipeg, Manitoba, Canada in an area where permafrost is degrading rapidly. Soil sampling and installation of instrumentation (temperatures, settlements, lateral deformations and pore water pressures) was undertaken in October 2008.

Thaw Responses in Degrading Permafrost

Volume 1: Project Management; Design and Construction; Environmental Issues; GIS/Database Development; Innovative Projects and Emerging Issues; Operations and Maintenance; Pipelining in Northern Environments; Standards and Regulations, 2006
The Norman Wells pipeline has operated for over 20 years, transporting crude oil from Norman Wells, Northwest Territories to Zama, Alberta. The pipeline route traverses 869 km of discontinuous permafrost. The stability of the slopes along the route required that rapid thawing of ice-rich permafrost be avoided, lest the high porewater pressures that ...

Highway embankments on degrading and degraded permafrost

2011
Global warming is affecting transportation systems in northern Canada. Thawing permafrost and expanding infrastructure systems require improved designs, construction and maintenance. The paper provides information about sampling, testing, instrumentation, and numerical modelling on two instrumented sections of provincial roads in Northern Manitoba.

Engineering Studies for Degrading Permafrost

Current Practices in Cold Regions Engineering, 2006
Polar mean annual air temperatures have been on the rise for the past few decades and are expected to continue to rise (Hassol, 2004). Because of this, mean annual ground temperatures are rising as well, and civil engineering projects in the circumpolar north are at risk due to the possible thawing of their frozen founding soils.

Permafrost Degradation: Legal Consequences

Ecological Law
This article identifies current problems of permafrost degradation in the context of the emergence of a new sphere of legal regulation, primarily in Russia as a subarctic country. Various legal consequences of this phenomenon, especially those arising outside the sea, on land, are very sensitive to ecosystems and humans. It is proposed to begin solving
